PPE kits-
Coveralls are commonly made from high-density polyethylene (HDPE) formed into a nonwoven fabric that allows heat and sweat to leave the suit while preventing liquids and aerosols from entering it. The sewing of coveralls can be the most difficult part to get right. Seams are closed by putting tape on them to strengthen them and keep them from leaking. However, places where multiple seams join (such as the armpit) can be difficult to seal properly, often making suit construction a trade secret. Lastly, the interfaces on the suit, including the zipper, cuffs, and the edge of the hood or collar, are made liquid-tight to prevent leakage. Depending on the application, cuffs and hood/collar interfaces can be elastic or liquid-tight seals. Zippers can have fabric flaps that cover them or be specially made as liquid-tight zipper assemblies.What happens when they are disposed in bins?
Never put any PPE (i.e. gloves, masks, wipes, cloths) in your recycling bin/bag under any circumstances. They are not suitable for recycling.

Any PPE that has not been in contact with an infection source can be disposed of as general waste. In a situation where PPE waste is exposed to possible cases, the following is to be done:-
1. PPE must be put in a plastic waste bag and tied when full.
2. This plastic bag should then be placed in a second bin bag and tied.
3. It should then be stored in a safe and secure place for 72 hours or until the individualâ€™s test results are known.

PPE waste should be stored safely and kept away from children. You should not put your PPE waste in communal waste areas or on the street for collection. Please wait with this until negative test results are known or the waste has been stored for at least 72 hours.
->If the individual tests negative, PPE waste can be put in with the general waste. It is not necessary to double bag your PPE waste if it has not been exposed to the virus. All of the general waste we collect is sent to SELCHP for safe destruction by default
->If the individual tests positive, then store it for at least 72 hours and put it in with the general wasteFace masks, gloves, and wipes are made from multiple plastic fibers, primarily polypropylene, that will remain in the environment for decades, possibly centuries, fragmenting into smaller and smaller microplastics and nanoplastics. A single face mask can release as many as 173,000 microfibers per day into the seas, according to a study in Environmental Advances.

PPE waste should be stored safely and kept away from children. You should not put your PPE waste in communal waste areas or on the street for collection. Please wait with this until negative test results are known or the waste has been stored for at least 72 hours.
->If the individual tests negative, PPE waste can be put in with the general waste. It is not necessary to double bag your PPE waste if it has not been exposed to the virus. All of the general waste we collect is sent to SELCHP for safe destruction by default.

The pandemic has also seen increased production of disposable packaging, as consumers have bought more takeout food, and as bans of single-use plastics, including shopping bags, were suspended because of fears that reusables would spread the virus. At the same time, in part due to cuts in cash-strapped municipal budgets, a third of the recycling companies in the United States have been partially or completely shuttered.Suggest ways (based on your pre work)
REUSE-  dispose of masks after their 1st time in use.
REVIVE- Social distracting
REDUCE- Physical contact
RECYCLE- Recycle only the things which can be, items such as PPE kits are not designed or meant for recycling
RECOVER-
Step 1 - Self Isolate. As soon as you have tested positive for the Coronavirus, you must self-isolate as soon as possible. ...
Step 2 - Regular monitoring.
Step 3 - Medications.
Step 4 - Seek medical attention.
Step 5 - Stay calm.

<hr color="yellow" size="4"width="100%"align="left">
Most face shields are made out of fabrics like <a href="https://www.bing.com/search?q=polyester%20meaning&pc=0AGL&ptag=C15N1AA57877ED9B&form=CONBNT&conlogo=CT3210127">polyester</a> and <a href="https://en.wikipedia.org/wiki/Polycarbonate">polycarbonate</a>. Though these masks help keep bacteria at bay, but these shields are also plastic-based. This material makes the shield liquid-resistant. PPE kits are made of polypropylene. Polypropylene is a polymer plastic that is a member of the <a href="https://www.bing.com/search?q=polyolefin+meaning&qs=n&form=QBRE&sp=-1&pq=polyolefin+meaning&sc=1-18&sk=&cvid=86DA214F1F6C45EAB0E78CFFD7745F6A">‘polyolefin’</a> family. Hence, with plastic comes the issue of disposal as plastic remains as it is. Nowadays due to the pandemic the manufacture of these materials have increased due to the increased needs of the <a href="https://th.bing.com/th/id/OIP.GJ84mzI3ma2K3gtz93R9YgHaHa?pid=ImgDet&rs=1">faceshields</a>, and <a href="https://th.bing.com/th/id/R.db67845563d55c63f8140c5b2cdbab29?rik=OVu8XGBo0dmKMQ&riu=http%3a%2f%2fwww.unifabindia.in%2fwp-content%2fuploads%2f2020%2f05%2fIMG-20200509-WA0005.jpg&ehk=bkbEpAtD2u4VdWPvoIzeJ4WcCN4FPr8wD%2b5ao2dBvaA%3d&risl=&pid=ImgRaw&r=0">PPE kits</a>. Such activities results in more manufacture of plastic, that is harmfull for the environment.

<ul>
<li>Never forget to dispose of your masks, gloves, tissues and empty bottles of sanitisers only in bins with a lid.</li>

<li>Try to use reusable masks over disposable masks to avoid excess disposable waste. N95 masks are a must only for those coming in contact with COVID-19 patients. Also try to use the same sanitiser bottles. </li>
<li>Have proper disposal bins with lids.</li>
<li>Do not discard used safety gears in open or in public spaces.</li>
<li>Have separate boxes/containers for disposal.</li>

<li>Do not use masks and other safety gears made of polypropylene as these are difficult to dispose.</li>

<li>Please click<a href="https://youtu.be/KJxlouevTMI"> here</a> to watch a video regarding guidelines on disposing masks and PPE kits.</li>

2)What happens when they are disposed in bins? And are they contributing to pollution?
Yes,they do contribute to pollution annd their disposal has become a challenge. Used PPE Kits are required to store separately for a minimum 72 hours for disposal along with solid waste after cutting or shredding. They also create problems in this matter like any other plastics. Most surgical masks and face shields are generally non-biodegradable but options are available in the market......People often do use reusable masks which ca be washed,Some types of face shields may be cleaned, disinfected, and reused (depending on the manufacturer's instructions).

3) Research on ways, guidelines, remedies made / to be made to take care of this new normal demand and disposal

Every day, nearly 3 lakh kits are produced in India. With disposal of PPE kits increasingly becoming a challenge, a particular type of biodegradable material was proposed by a Bengaluru college at a recent innovation challenge on Covid-19: The use of polymer-based coveralls.This Mission is a work in progress,but will be a great improvement for the planet.The best solution right now is to first disinfect the used materials and then send them for recycling. Other than that, a remedie is to use home-made PPE kits help and guidelines for this can be found on the net.

4)Suggest ways:
One of the most common and simplest suggestion is to use reusable face masks after washing, making PPE Kits at home using waste materials like plastic from old folders for face shields etc. (many tips based on the making of face shield at home is also available online) and reducing the demand for these by following simple precautions before and after travel or avoiding uneccessary travel during peak crisis of COVID at all.Reforestation,or simple planting a tree is an underrated solution to all the problems directly and directly. All this is a small step towards a big change for the betterment of the planet and future.

THANK YOU

School Holiday Homework

During the 2020/21 we were required to wear masks/pp kits/Face Sheilds and santize our hands before and after doing something to protect ourselves. I noticed that alot of people were wearing masks/ face sheilds, etc. However upon arrival I noticed that many people were discarding their masks etc and that the bins were overflowing with them. This in my eyes is a problem that needs to be solved. Before I move on to proposing a solution, let me first tell you how these masks, face sheilds. etc are made!

Would you like to change the border?

There are 4 steps in making a mask:

1. Raw materials used are polypropylene polymers Those polymers require a
â€“ Special grade
â€“ High Melt Flow Index (MFI)

2. The middle layer in a medical mask is made with a nonwoven meltblown process featuring electrostatic charging
â€“The two outer layers are made with the nonwoven spunbond process.

3. The 3 nonwovens layers are then calendered and together form the filter media.

4. The filter media is pleated and seamed in a converting line that delivers the medical face mask.

Personal protective equipment is made of plastic and isn't recyclable.
Now itâ€™s being found everywhere on earth, including the oceans.
The solution isnâ€™t complicated: Throw them away.

The problems created by PPE litter have arrived at a complicated time in the effort to curb plastic waste. The amount of plastic waste accumulating in the oceans is forecast to triple in the next 20 years, with no real solution on the horizon. If every corporate pledge to use more recycled plastics were kept, the shift would reduce that projected tripling by just 7 percent.

Itâ€™s been over six months since COVID-19 swept across and ravaged the world, and in an effort to contain this unprecedented outbreak, face masks have become a necessity. However, an increase in the use of disposable surgical face masks is also creating unwanted impacts on our environment, evidenced by piles of discarded face masks found near the coasts of Hong Kong, the United States, France, Mainland China, and Taiwan. Undoubtedly, face masks are now an environmental, as well as social, phenomenon. Source- GreanPeace.org

The World Health Organisation (WHO) recommends discarding them in the "correct" rubbish bin immediately after use and not reusing them. What is the "correct" bin? Masks and other disposable material that are used to contain the pandemic, such as gloves, must not be disposed of in the recycling bin with packaging, cans, etc. or with organic waste. Do not throw them away with your general household rubbish.

Why do I have to complete a CAPTCHA?

Completing the CAPTCHA proves you are a human and gives you temporary access to the web property.

What can I do to prevent this in the future?

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.

Another way to prevent getting this page in the future is to use Privacy Pass. Check out the browser extension in the Chrome Web Store.

Reduce:- Purchase products that require less packaging or to limit the waste you are producing. .

Reuse:-Use a travel mug or reusable water bottle and avoid single-use bags.

Recycle:- Paper, plastic, glass, magazines, electronics, and more can be processed into new products while using fewer natural resources and less energy. This is the 3 Râ€™s mantra.

b) Represent symbolically the practices that you and your family wish to achieve this year to help the environment.
They are:-
-Using Reusable cotton bags and washable bags

-Use ecological laundry detergents with natural, biodegradable ingredients.

-Buying products with little packaging and more

______________________________________________________________________________________________________________________
Because of the pandemic, the usage of the masks, PPE kits, and face shields have increased in a great extent. While we use these, we also have to know how they are made, by which material they are made of and how they are disposed. So letâ€™s know about it! How are masks, PP kits and face shields made? How are masks made?
-The middle layer in a medical mask is made with a nonwoven meltblown process featuring electrostatic charging. The two outer layers are made with the nonwoven spunbond process. The 3 nonwovens layers are then calendered and together form the filter media.

-the material most commonly used to make them is polypropylene, either 20 or 25 grams per square meter (gsm) in density. Masks can also be made of polystyrene, polycarbonate, polyethylene, or polyester.
How are PPE (Personal Protective Equipment) Kits made?
-PPE kits are made from 65% polyester and 35% cotton

-The most common materials in disposable in these gowns are Polypropylene Spunbond and Polypropylene Spunbond-Meltblown-Spunbond (SMS), which are 3 layers of non-woven fabrics, are the most common materials in disposable isolation gowns.
How are face shields made?
-Faceshields cut from extrusion sheets provide better impact resistance than injection molded faceshields because extrusion sheets are made of high molecular weight plastic pellets while injection molding must use lower molecular weight plastic pellets
Is the disposal of these items contributing to pollution? Yes, it is contributing to pollution
-The system boundary of the study is from cradle to grave comprising raw material extraction and processing, production, packaging, distribution, use, and disposal as well as transport and waste management along the supply chain. Eleven environmental impacts have been estimated. The results suggest that the global warming potential of a disposable medical mask is 0.02 g CO2-eq.

In total, 52 billion disposable medical masks used worldwide consumes 22 TJ of energy in 2020. The global warming potential of disposable medical masks supplied in a year of the COVID-19 pandemic is 1.1 Mt CO2 eq.
The ways guidelines, remedies made / to be made to take care of this new normal demand and disposal *How to wear a mask :-
-It should be noted that your mouth nose chin should be covered with the mask the coloured side facing outside

-Only remove the used mask holding the ear loops or the elastics of the mask

- Fold the mask and wrap it into a tissue paper or keep it in a plastic cover and throw it in the dustbin *NOTE THAT NEVER THROW A MASK IN THE RECYCLE BIN*

-Then wash your hands again thoroughly using soap and water

*Experts said reusable cloth face masks are a more sustainable option than single-use disposable masks, and some companies further incorporate recycled fabric into their masks, as well as organic materials. By using cloth masks the mask usage will reduce and we can wash it and reuse it again!
THE WAYS TO RECYCLE REUSE AND REDUCE AND REFUSE IS:- -Use cloth masks, we can wash them and use it again. This reduces the the mask pollution in the environment
-Make sure that you dispose the make and other PPE items carefully

-We can use the organic masks that are made from the bark of the trees and more
Here is the end of this project based on the three Rs.
Hope you had a good time going through it!

Have a great day ahead!~ :)

Coveralls

Gloves

Masks

Face Shields

COVERALLS

Coveralls are commonly made from high-density polyethylene (HDPE) formed into a nonwoven fabric that allows heat and sweat to leave the suit while preventing liquids and aerosols from entering it. The sewing of coveralls can be the most difficult part to get right. Seams are closed by putting tape on them to strengthen them and keep them from leaking. However, places, where multiple seams join (such as the armpit), can be difficult to seal properly, often making suit construction a trade secret. Lastly, the interfaces on the suit, including the zipper, cuffs, and the edge of the hood or collar, are made liquid-tight to prevent leakage. Depending on the application, cuffs, and hood/collar interfaces can be elastic or liquid-tight seals. Zippers can have fabric flaps that cover them or be specially made as liquid-tight zipper assemblies.

GLOVES

Medical gloves can be made of several different types of rubber, from latex to natural rubber to nitrile. Rubber gloves are made by dipping clean ceramic or aluminum molds shaped like hands into calcium nitrate, a coagulant, and calcium carbonate, which helps the gloves slide off the forms. The forms then are dipped into liquid rubber, with the glove thickness determined by how long theyâ€™re in the tank. Latex gloves are dipped in hot water and chlorine to reduce potential latex allergy symptoms in wearers, and then theyâ€™re vulcanized to make them more elastic and tear-resistant. Gloves are rinsed a second time and the cuffs are rolled, then theyâ€™re dipped into corn starch and dried. Either air jets or workers then remove the gloves, and theyâ€™re tumbled with hot air to get rid of excess powder. Finally, gloves are tested by filling them with air and water to make sure theyâ€™re free of defects. Depending on the level of testing, higher-performing batches are designated as medical gloves, while lower performance batches that still pass minimum qualifications become industrial gloves.

MASKS

Surgical masks are made using specialized machinery, then sterilized. Nonwoven polypropylene and textile material is fed from bobbins into machinery that cuts and ultrasonically welds it together. Surgical masks typically have one layer of textile material surrounded by other layers of nonwoven material on both sides, making for 3-4 layers total depending on the mask. The machine attaches other parts like ear loops or metal strips before the masks are sterilized and packaged.

FACE SHIELDS

Face shields are simple PPE that consist of a visor, a lightweight plastic or metal frame, and a suspension system that attaches the shield to the wearerâ€™s head. Theyâ€™re generally worn over other PPE such as masks and goggles. Visors can be made up of plastics such as polycarbonate, propionate, acetate, polyvinyl chloride, and polyethylene terephthalate glycol (also known as PETG). The plastic is often given anti-glare, anti-fog, anti-static, or other coatings. The attached suspension systems can include elastic straps, Velcro, headbands, glasses-type temple bars, pin-lock, or ratchet systems.

Q2. What happens when they are disposed in bins?

A. If they are disposed of in bins, they will have to go to a dump yard. First, chemicals contained in the masks are a potential threat to our environment. In addition to non-woven fabric and activated carbon, medical face masks also contain large amounts of polypropylene (PP), which is a type of commodity plastic that takes a long time to degrade and releases a lot of toxic substances during the process

Secondly, the Discarded face masks can become floating marine debris and impact the marine ecosystems. If left unaddressed, those face masks might be mistaken by some marine animals for food. Moreover, plastic particles released from the degradation of those face masks will also remain in the oceans and build up in the food chain for years to come, eventually becoming a detriment to human health.

Rivers and mountainous areas may become dumping grounds, which not only could hinder our pandemic response efforts to properly dispose of single-use masks, but also wreak havoc on wildlife. From a social risk perspective, a spike in the amount of disposed waste might lead to an increase in the demand for incinerator capacity. In the past, there have been instances of residents protesting against the waste incinerator. If we are facing the need of building new incinerators, whether it is for general or medical waste, they will not be welcomed by any neighborhood.

Q3. Is it contributing to pollution?

A. Yes it is contributing to pollution due to reasons mentioned above.

Q4. Ways to reduce this waste by reusing or the proper disposal of masks.

Cloth Masks are not to be disposed and can be reused by washing and drying in the sun atleast once in a week.

Surgical masks should be removed carefully touching only the strings, and folding half inwards, such that droplets from the mouth and nose are not exposed. Then, fold the mask into another half, until it looks like a roll. The mask can also be wrapped with its ear loops so that it will not unravel. Then wrap the mask in a tissue paper or polythene bag and immediately discard it in the yellow waste bag. This will prevent the spreading of the virus. If itâ€™s dry and the layers and shape are intact, put it in a zip lock pouch with a desiccated gel. The gel absorbs moisture and keeps the mask dry. If the mask is intact and not torn, it can be reused for 3 days.

N95 respirators are not very safe to be reused and should be disposed until and unless you are not ill. Now, gently remove the mask so as not to disseminate contaminants on the mask. Place the mask in a plastic bag or zip-lock bag. You can also store them in a breathable container such as a paper bag between uses. Secure the bag tightly. Place the plastic bag into a garbage can or biomedical waste disposal unit.

Surgical masks, once simply a strip of cloth tied around the face of a doctor or nurse, are today manufactured using non-woven fabrics made from plastics like polypropylene to filter and protect. They are also available in many different styles and grades depending on the level of protection the user requires.

Masks are made of three layers of fabric â€“ Inner layer of absorbent material such as cotton, middle layer of non-woven non-absorbent material such as polypropylene and outer layer of non-absorbent material such as polyester or polyester blend. PPE kits are also made using polypropylene. Face shields are made using polycarbonate because of its optical clarity and impact resistance. All the three items are made using a type of plastic which is hazardous to environment on a long run.

All of these when thrown directly into a dust bin would still carry germs on it and can spread the infection. They need to be discarded safely. There is also a possibility of animals taking it for food and swallowing it. Ever increasing use of the above is leading to increased land fill and medical waste. The material they are made up of, is causing plastic or microplastic pollution to the environment.

To combat the high surge in demand for masks, PPE kits and face shields, directive was launched to educate people on which kind of mask has to be worn by whom. Steps were taken to educate on how these masks need to be disposed post usage. Urge to use re-usable masks and face shields was also advocated.

My family and I have tried to avoid the usage of plastic by lessening the use of plastic water bottles,
using the four golden R's, carrying reusable bags, by asking for plastic-free Packaging etc.

~ QUESTION A
My family and I have used these R's in many ways.
-> REDUCE : by buying products with less packaging.
-> REUSE : reusing polythene bags for shopping.
-> RECYCLE : recycling old books and papers.
-> REFUSE : refusing the wastage of resources by buying what we only need.
-> RESIST : resisting to buy products that we already have.
-> RESTORE : restoring the nature by conserving plants, cleanups in community etc.
-> REFOREST : reforesting plants by planting saplings etc.
-> REGROWING : regrowing plants to use natural processes to your advantage.

~ QUESTION B
My family and I are trying to make the Earth a greener and a better place.
In order to achieve this, we are trying to save electricty by limiting time for the A.C
-> resisting the usage of plastic bags and using jute / cloth bags.
-> by wearing reusable masks instead throwing them away.
-> walking instead of the usage of vehicles.
-> carpooling when going to school.
~ QUESTION C
We can protect our environment by :-
-> using a fewer chemicals, this way both the soil and the water will be
free of pollution.
-> educating other family members and community about the importance of our world
and how we can save it.
-> by practicing afforestation and planting trees.
However we cannot achieve this now because there are a lot of people in the world
who do not follow the rules and cooperate in such events. They throw non biodegradable
waste on soil, waste water and electricity etc. The population too will grow soon
and we will require more resources to satisfy our needs which can lead to depletion
of them and there will be very few people who will follow the rules. However it isnt
too late to save our planet, we can still save it by playing a part in events like
swachh bharat and do our bit by limiting ourselves.

~ EXTRA QUESTION 1
-> masks : masks have four layers of silk and mixtures of fabrics to make breathable face
masks. The inner layer is absorbent layer like cotton, the middle layer is a non
woven material whereas the outer layer of the non absorbent matieral is like polyester.
These are then woven into masks
PPE kits consist of gloves, gowns, eye protection, mask and shoe cover.
-> gloves : the material used commonly for making gloves is latex which is a form of rubber.
-> gowns : gowns are made of cotton or polyester or cotton fabrics.
-> eye protection : eye protection is usually achieved by wearing eye glasses.
Eyeglasses frames are typically made of either metal or a type of plastic called
cellulose-acetate
-> shoe cover : shoe covers in PP kits are usually non woven and are high ankled.
It is made up of durable polypropylene coated fabric that meets the safety standards.
masks : masks have four layers of silk and mixtures of fabrics to make breathable
face masks. The inner layer is absorbent layer like cotton, the middle layer is a
non woven material whereas the outer layer of the non absorbent matieral is like
polyester. These are then woven into masks
-> Face shields : face shields are made of quality thermoplastics. They are usually made to
withstand heat, impact, chemicals. This is to prevent the spread of communicable diseases.
Polycarbonate and Polyester Film are two common plastic materials used in the development
of surgical face shields.

~ EXTRA QUESTION 2
Due to covid, the plastic waste is increasing and there is a huge increase in of pollution
because the people throw masks, PPE kits and other biomedical waste on the roads, soil etc.

~ EXTRA QUESTION 3
There is a huge increase in the pollution as gloves and masks are being thrown on the road
PPE suits lying in the hospitals, sanitizers and shields are being thrown as house waste.
however notwithstanding the unprecedented health and environment crisis, the experts said
there are ways to minimise the damage.

~ EXTRA QUESTION 4 & 5
DISPOSAL OF BIOMEDICAL WASTE We can dispose ppe kits in many ways such as on-site incineration.
this method of decentralized incineration will reduce multiple contact points who handle
the infected PPE kits. The medical waste can also be buried into a pit or a facility for
sharp compression. Once the pit is full it should be it should be completely sealed
to finish the process of burial. the WHO reccommends discaring masks and gloves in the correct
rubbish bin immediately after use Masks and other disposable materials like gloves that
are used to contain in the pandemic must not be disposed of in the recycling bin with cans,
packaging etc. the materials should be placed into two small plastic bags - one inside each other.
tie the bags firmly and throw them away with your general domestic waste.

â”€â”€ My family and I want to help the environment and make it a better place for all.
ãƒ»Various resouces like electricity, water, soil etc. are being used leisurely by us presently but if we all take up small acts to conserve these, it will benefit us greatly. ï¿« We will restrict the use of ACs, Fans and Lights when not needed.
ï¿« We will use cloth and resuable masks instead of disposibles.
ï¿« We will walk to nearby destinations instead of using vehicles.
ï¿« We will use compost instead of fertilizers for the betterment of soil.

â”€â”€ We can protect and preserve our emvironment by :
ï¿« Limited number of children to conserve resources and betterment of all.
ï¿« Switch to renewable energy such as wind energy to conserve energy.
ï¿« Using energy efficient light bulbs to reduce greenhouse gas emissions.
â”€â”€ Why we cannot achieve them currently:
ï¿« The people of our world take our resources for granted and forget about the well-being of the future generations. They pollute the soil by throwing non-biodegrable waste on the streets, the water with the industrial waste, air with factory smoke etc. and the world is slowly degrading. No matter the rules set by goverments and the fines imposed for these the people do not cooperate. However its not too late for our community to change and help the earth to become a better, greener and safer place.
â”€â”€ Information on items used to control the spread of infectious diseases(Covid19):
ï¿« MASKS : The inner layer is made of an absorbent layer like cotton, the middle of a non-woven material like polypropylene and outer layer of non-absorbent material like polyester. These non-woven layers are then woven into a breathable and efficent face mask for medical purposes and prevention of the spread of infectious diseases.
ï¿«PP KITS : PP Kits are a combination of gloves, a gown, eye-protection, shoe-cover and a face mask. Gloves are usually made of latex, a form of rubber, Gowns can be made of cotton fabric or polyester. Eye protection is achieved by wearing eyewear with frames made of either metal or a plastic called cellulose-acetate.
ï¿«FACE SHIELDS :Face shields are made of quality thermoplastics can be made to withstand heat,chemicals, to prevent the spread of infectious disease etc. Polycarbonate and Polyester Film are two common plastic materials used in the development of surgical face shields. Both materials are transparent, lightweight and can be easily processed into almost any shape to meet our needs.
â”€â”€ Disposal of medical waste :
Used face masks are â€œunrecyclableâ€ due to the fact that they may be contaminated and could potentially lead to indirect infection and viral transmission if they enter the recycle system so Fabric/Cloth masks are generally washed and reused whereas disposables are to be discarded carefully whereas Used PP Kits (including all its contestants)are generally labelled as infectious or offensive, which means disposal needs to prevent the transmission of disease to the wider population.The most effective way to do that is to burn it as high temperatures destroy viruses.
â”€â”€ Pollution because of untreated medical waste :
The crisis of plastic and biomedical waste is deepening with each Covid case as millions of people use and throw face shields, surgical masks, gloves and PPE suits, once used primarily in hospitals and now an indispensable part of everyday life. The outcome of the pandemic can be seen everywhere - PPE suits lying discarded behind hospitals, surgical masks and shields being thrown as part of household waste and, sanitiser bottles and gloves found in street corner garbage dumps. With waste disposal mechanisms less than perfect in India and the 'plastic footprint' becoming larger by the day, concerns on plastic waste choking the planet and worries about safety are mounting. These past 2 years have greatly increased the amount of pollution on our streets not only because of the medical waste but also the normal littering of the people.
â”€â”€ Ways, Guidelines and remedies :

Keep separate color coded bins/bags/containers in wards and homes to maintain proper segregation of waste. As precaution double layered bags should be used for collection of waste so as to ensure adequate strength and no-leaks.Dedicated sanitation workers are hired separately for biomedical waste and general solid waste so that waste can be collected and transferred timely to temporary waste storage area.Collect used PPEs such as goggles, face-shield, Plastic Coverall, Hazmet suit,nitrile gloves into Red bags/Covid-19 labeled bags.The medical waste can also be buried into a pit or a facility for sharp compression. Once the pit is full it should be it should be completely sealed to finish the process.

Question and Answers

Q.How have you thought of reducing the use of plastic in your family?
Ans.We are using paper or jute bags instead of plastic bags for shopping.

a) Represent symbolically the practices you and your family have started for this with these Rs.

Ans: We are reducing the use of plastic and refusing it as much as we can.
We are recycling plastic to make plant containers instead of buying it.

b) Represent symbolically the practices what you and your family wishes to achieve this year to help the environment.

Ans:By walking to School or taking a cycle, avoid taking cars or Carpool when possible.

c) Represent symbolically the practices that you feel are important to protect the environment and why you cannot achieve them now.

Ans: Plastic bags pollute not only our water but also our land.Plastic bags pollute not only our water but also our land.Plastic bags pollute not only our water but also our land. Plastic bags pollute not only our water but also our land.We cannot achieve to ban plastic right now because people are used to using it so it will be possible to ban plastic in future.

Ponder....

3. How are masks, PP kits and face shields made?

Ans: Gowns can be made of cotton or polyester/cotton fabric and used with aprons. Woven fabrics can be used for making masks as long as a suitable middle layer for filtration is available, for example interlinings. These masks, however, should not be used by front line health care personnel Coveralls, double gloves, or head covers (hood) that cover the head and neck used in the context of filovirus disease outbreaks (e.g. Ebola virus) are not required when managing COVID-19 patients.

4. What happens when they are disposed in bins?

Ans: After completing a task, for example a ward round, all single-use PPE is discarded using standard infection control precautions.

5. Is it contributing to pollution?

Ans: Coronavirus waste has become a new form of pollution as single-use personal protective equipment (PPE) floods our ocean.

1. Masks, PP kits and Face-shields are made with none other than plastic. We waste these by throwing them away. They are harmful for the enviroment.

2. When these disposed in bins the are thrown away into landfills and as you know plastics don't dicompose into the soil and they harm the soil making in infertile.

3. Is it contributing to pollution?-Yes it is, it pollutes the soil as it does not decompose and causesthe soil to become infertile.

4. Ways in which we can help this situation-

We could keep separate bins for these masks, PP kits and Face-sheilds in public places.

These Masks, PP kits and Face-sheilds will be disinfected and recycled

To top it of a sign on top of the bin saying that- ALL MASKES, PP KITS OR FACE-SHEILDS MUST BE DISPOSED OF IN THIS BIN.

Also people could use cloth masks, which are reuseable instead of use and throw masks.

5. How I and My Family are reducing the use of plastic-

1. Three practices me and my family have started for this with these R's

Reuse- we reuse cloth/plastc bags and plastic bottles instead of throwing them away.

Reduse- we do not use plastic bags or plastic bottles unless needed.

Refuse- we refuse to buy platic bags at stores

2. Three practices what me and my family wish to achieve this year to help the environment

We will try to buy less plastic bags/bottle.

We will try to give the plastic items to recycling.

We will not use use and throw maskes and throw them away.

3. Few practices that I feel are important to protect the envirment

We must not throw trash on the roads, we must throw them in a dustbin.
-Awarness must be spread about this and those who litter must be charged with a fine.

Trash must be cleaned of the roads, The municipal cooperation must take this resposibility.
-These plastic items are eaten by animals which have a lot of health problems.

Ways we save the environment:-

||PPE gowns are used by medical personnel like doctors and nurses.Any item of PPE imposes a barrier between the wearer/user and the working environment. This can create additional strains on the wearer, impair their ability to carry out their work and create significant levels of discomfort.||

||The middle layer in a medical mask is made with a nonwoven meltblown process featuring electrostatic charging. The two outer layers are made with the nonwoven spunbond process. The 3 nonwovens layers are then calendered and together form the filter media.||

||When masks and PPE kits are disposed in dustbins most of them overflow and when they are taken away they burn them with can release extremely harful gases and causes global warming. PPE kits and masks must not be disposed in that way.||
Here's how you should dispose PPE kits and masks:-
||A PPE kit must always be removed under the guidance of a trained professional. A separate area, ideally a sanitised environment, must be identified. Separate containers should be available to store reusable items, when disposing off a PPE kit, all biomedical waste, including masks, gloves and PPE kits should be disposed in a yellow bag. Upon disposal, the area should also be sanitised with sodium chloride.||

Thank You!!

Question and Answers
1. How have you thought of reducing the use of plastic in your family?
Ans). We are using paper or jute bags instead of plastic bags for shopping.

A) Represent symbolically the practices you and your family have started for this with these Rs?
Ans) We are reducing the use of plastic and refusing it as much as we can.We are recycling plastic to make plant containers instead of buying it.

B) Represent symbolically the practices you and your family wish to achieve this year to help the environment?
Ans) By walking to school or taking a cycle, avoid taking cars or carpooling when possible.

C) Represent symbolically the practices that you feel are important to protect the environment and why you cannot archive them now?
Ans) Plastic bags pollute not only our water but also our land. The total amount of energy required to drive a car for one kilometer or 0.5 miles is the equivalent energy required to produce nine plastic bags. In truth, petroleum-based plastic bags never degrade. Instead of the plastic degrading, It is broken down into smaller pieces that are swept down and end up in the oceans, which are then consumed by wildlife. We cannot achieve banning plastic right now because people are used to using it so it will be possible to ban plastic in the future.

Q3)How are masks, PP kits, and face shields made?
A. Gowns can be made of cotton or polyester/cotton fabric and used with aprons. Woven fabrics can be used to make masks as long as a suitable middle layer for filtration is available, such as interlining.

Q4) What happens when they are disposed in bins?
A. All the disposed PPE kits are dicarded using standard infection control protocals.
Q5) Is it contributing to pollution?
A. Coronavirus waste has become a new form of pollition as single-use PPE (Personal Protective Equipment)flood our ocean.

ANSWER

Practices that I feel are important to prptect the environment are : do not pollute water and air ,do not cut trees down and do not throw plastic waste into the water bodies . I cannot achieve them now because huge factories and industries are polluting our environment.

Let’s Spread the good Word!!

How are masks, PP kits and face shields made?

ANSWER

Masks are made with cloth to protect us from the virus from entering our nose . PP kits contain suit , face shield , masks , gloves , cap and gown . Face shields are made of Polycarbonate because of its optical clarity and impact resistance . Where the goal is mainly to protect the face and eyes against contact with bodily fluids .

What happens when they are disposed in bins?

ANSWER

After they are disposed in bins they are taken to the dumpyard and the respective authorities will take them to sterilise

Is it contributing to pollution?

ANSWER

If they are made of plastic they are contributing towards the pollution and if they are made of cloth or paper they are not contributing .

Research on ways, guidelines, remedies made / to be made to take care of this new normal demand and disposal

ANSWER

Since 2 years whole world is facing this pandemic situation because of covid-19 in order to protect ourself from this infection we have adapted ourselfs with few new changes such as wearing mask / face shields / frequent sanitisation of hands / avoiding crowded places / sterilising the things brought from outside / isolating ourselfs if there are any covid symptons and onsulting the doctor . Disposing the masks in separate bins (yellow bin) .

How are masks, PP Kits and face shields made?

â€¢ Masks require raw materials such as polypropylene polymer for production. The middle layer in a medical mask is made with a nonwoven meltblown process featuring electrostatic charging. The two outer layers are made with the nonwoven spunbond process. The 3 nonwovens layers are then calendered and together form the filter media. Personal protective equipment or PPE is crucial to keep healthcare workers on the COVID-19 pandemic's frontline safe. PPE works as a barrier between an individual"s skin, mouth, nose, or eyes and viral and bacterial infections. PPE consists of garments placed to protect health care workers or any other persons from getting infected. These usually consist of standard precautions: gloves, mask, gown. Face shields are made up of polycarbonate and sheets of acetate and plastic the plastic is burnt to bend the sides. The straps are made of cloth.

What happens when they are disposed in bins?

â€¢ When these items are disposed most of them are burnt, so that the virus also dies along with the pp kits / masks. Sometimes the masks and pp kits are not disposed correctly and they become floating marine debris. This might imapact the marine ecosystems such as fishes, dolphins.

Is it contributing to pollution?

â€¢ Yes, masks, ppe kits, and face shields are contributing to pollution. As masks and pp kits are not recyclable because it might be contaminated and might be a threat to the recycle system,there is nothing we can do about it.

Ways to take care of it:-

â€¢ It is recommended to discard them in the "correct" rubbish bin immediately after use and not reusing them. What is the "correct" bin? Masks and other disposable material that are used to contain the pandemic, such as gloves, must not be disposed of in the recycling bin with packaging, cans, etc. or with organic waste. The materials should be placed into two small plastic bags - one inside the other. Tie the bags firmly and throw them away with your general domestic waste. It is recommended to write RISK OF CONTAMINATION on the waste if it has been in contact with a person affected by the virus.

Ways based on prework:-

REUSE:- We can reuse cloth masks by washing them. The masks should be washed by the person wearing them only.
