These risks turn many workers away from the industry.

Expensive or Inadequate Services

In order for a city to have an effective recycling system, adequate services (like separate bins and safe recycling centers) are needed.

Some cities just don’t have these resources or the government support to have adequate recycling services.

Low Market Demand for Recycled Materials

For businesses, buying recycled materials is like buying second-hand at full. Especially during the COVID-induced decrease in oil prices, the price of “virgin” plastics is much lower than the price of post-consumer plastics.

However, the industry is seeing a rebound in the value for recycled content in produciton and packaging.  With supply chain shortages, virgin materials are harder and more costly to acquire.  Multiple global economic factors are supporting a rise in demand for recycled feed stock, leading to a larger need to capture quality materails and put them back into the circular economy.

The problem with these solutions, though, are that they heavily rely on the person to do what they want, and some people have certain habits or beliefs that they were taught whilst growing up, which may make it harder to tackle this problem.

What is homework?

Homework is basically a set of tasks given to students by teachers which should be done out of the classroom.Homework can be a great way to enhance learning and play an important role in achieving better academic results.

Source: https://inspiredtogetherteachers.com/10-reasons-why-students-dont-do-homework/

Reasons why students forgot to do their homework (I picked 5 that are more common) :

1)Students does not understand/does not know how to do the assignment

2)Students are overwhelmed as they have many homeworks to do

3)Students do not have the time to do the homework

4)Students do not understand the purpose of the assignment

5)Students lack the suitable environment to do the work

Advantages of doing homework:

 Source:https://www.emergingedtech.com/2018/03/homework-higher-academic-achievement-but-not-too-much/

1)It improves the student's memory and thinking skills.

2)Doing homework helps the students to learn how to manage time.

3)It helps the students to take more responsibility.

4)Homework helps the students to seek extra knowledge about the subject.

5)Homework leads a student towards independence over studying.

Disadvantages of not doing homework:

Homework is an important indicator used to measure students' ability to apply whatever they have learned in class. Doing away with them would deprive teachers of the means to assess their students' progress. Homework reinforces materials learned in class and enables students to memorize important concepts and theories.

**Does homework really help with a student's academical performance?

Source:https://onlinedegrees.sandiego.edu/education-inequity-and-homework/

School work assigned and completed outside of school hours is not without its benefits. Numerous studies have shown that regular homework has a hand in improving student performance and connecting students to their learning. When reviewing these studies, take them with a grain of salt; there are strong arguments for both sides, and only you will know which solution is best for your students or school. 

** From the research, doing homework does improve students academic performance.

Even with the history of debate over the merits of homework, there are significant gaps in the research record regarding its benefit to students. The focus of this study is on the association between time spent on homework and academic performance in science and math by assessing survey and transcript data from two nationally representative samples of high school students collected in 1990 and 2002. Using multiple linear regressions and controlling for students' background, motivation, and prior achievement, we investigated how much variance in science and math course grades and achievement test scores could be explained by time spent on homework in those classes. The results indicate that there is no consistent significant relationship between time spent on homework and grades, but a consistently positive significant relationship between homework and performance on standardized exams.

#1 problem:Students forgetting about their homework that is due soon.As a result,they will get scolded by their teachers

More research below :) 

______________________________________________________________

Targeted Audience: Secondary school students up to university students

Why the chosen targeted audience?:When students step into secondary school until their journey to university,they will have many subjects to take on which can result them in forgetting their homework.

Supported evidence:

A survey of 2,000 secondary school students has found that they would rather make up excuses – such as not knowing the deadline – than admit they are unsure about the topic.The study suggests that one in three (31 per cent) students regularly make excuses about homework and that as many as one in four pieces of homework are handed in late every day. Taking into account all UK schools, this would add up to one million late pieces of homework a day across the country.An average secondary school student gets six pieces of homework a week and spends an hour on homework every night according to the research. However, more than a third of the students do not believe that the homework they are set adds to their learning experience. The study also reveals that age 13 is the worst age for submitting homework on time, coinciding with a dip in attitudes towards homework.This comes after students tend to hit a “homework peak” at age 12 and before age 14 when punctuality begins to increase once again ahead of GCSEs. The survey found that students aged 13, in years 8 or 9, are:

Least likely to complete their homework on time (67 per cent).

Most likely to get parents or guardians to complete homework for them (23 per cent).

Most likely to think homework shouldn’t be given to them (54 per cent categorically say no).

Least likely to think homework adds to their overall learning experience (45 per cent think it doesn’t)

Current methods of reminding students:

1)Student organizer/handbook/diary

2)Online platforms such as google classroom

Nowadays technological development are used and can be found everywhere

As a student,I can see the applications of technology in the present education system such as: Providing students with PLDs(Personal Learning Device),uses online platforms for online lessons such as zoom making lessons more engaging like using Kahoot or Blooklet and creating platforms to spread around announcements such as Google classroom or WhatsApp Groups.

 Supported evidence:

Introducing social media in the classroom helps improve cognitive abilities such as memory, critical thinking, comprehension, creative thinking, and problem-solving skills.

From the above,I can infer that students benefit from using technological innovations in their education.Moreover,I feel that students get reminded best from using online platforms (from my current experience as a student).However from my experience,I noticed that teachers send in the reminder for the completion of the assignment very late minute such as the night before the due date.Therefore students who forgot about the homework would eventually remember it but will realize that it is too late to complete the assign.Therefore resulting them in failing to do the assignment. :(

What is air pollution? Air pollution refers to the contamination of our air with harmful gases and particulates. Globally, 9 out of 10 people breathe polluted air but many people are unaware of the potential health and environmental impacts of poor air quality.

What causes air pollution? Air pollution is caused when harmful gases and chemicals are released into the air. These pollutants include Particulate Matter (very small particles that get into our respiratory system), nitrogen oxide and sulphur dioxide. The majority of these pollutants are emitted through human activities like burning fossil fuels, vehicle exhaust fumes and emissions from agriculture and industry.


When?
When does air pollution happen?

Air pollution occurs when the air contains gases, dust, smoke from fires, or fumes in harmful amounts. Tiny atmospheric particles - aerosols - are a subset of air pollution that are suspended in our atmosphere. https://www.ucsusa.org/resources/does-air-pollution-affect-global-warming#:~:text=Air%20pollution%20occurs%20when%20the,be%20both%20solid%20and%20liquid.

Where?
Where does pollution occur? Mobile sources – such as cars, buses, planes, trucks, and trains. Stationery sources – such as power plants, oil refineries, industrial facilities, and factories. Area sources – such as agricultural areas, cities, and wood burning fireplaces. Natural sources – such as wind-blown dust, wildfires, and volcanoes. https://www.nps.gov/subjects/air/sources.htm#:~:text=mobile%20sources%20%E2%80%93%20such%20as%20cars,blown%20dust%2C%20wildfires%2C%20and%20volcanoes


Who?
Who is being affected?

Populations most at risk of health problems related to air pollution:

Why?
Why has no one addressed this issue? In the future, the world will face many new environmental problems, yet the scientific and policy research community will not necessarily recognize these problems as they come up. Which agendas environmental scientists and policymakers advance depends on many factors, including media attention and socioeconomic and historical dynamics. The identity and the values of the agenda-setters influence which issues are emphasized and which are neglected—purposely or unintentionally. Prioritizing environmental information is made even more difficult since the state of the environment is constantly changing and new scientific findings are constantly coming to light. The issues that do gain recognition may often be informed by outdated or incorrect data, even when more up to date environmental information may exist. A team led by Jari Lyytimaki at the Finnish Environment Institute examined how and why potentially important environmental topics may be left out of assessments, debates, and decisions by using light pollution as a case study. Their goal was to better understand what factors cause an issue to fail to receive attention and the implications of not prioritizing certain types of environmental information. Lyytimaki's team used pollution caused by lights as an example of a neglected environmental issue. Even though light emissions have increased rapidly and their effects can be measured by anyone—even without scientific equipment—light pollution has not been prioritized in assessment, management, and planning. Light energy emissions have grown rapidly since the 1950s, impacting rural and natural areas hundreds of kilometers away from urban light sources. Scientists have published many studies measuring the safety benefits of lighting, but research and assessments examining the biologically disturbing impacts are less common. The studies on light pollution that do exist document negative ecological, biological, medical, astronomic, and economic impacts of lighting. Lyytimaki's team believes light pollution is an emerging environmental problem still garnering interest that could potentially become a serious future challenge. The team identifies four dynamic and ever-changing forms of non-recognition or unawareness that may explain why light pollution is largely ignored, as well as potential solutions:

Recognized unawareness: a person suspects that light pollution may have negative effects, but thinks there is not enough information to determine how important light pollution may be. Similarly, the actor may not have the resources to use information that is available or may think the available information is imperfect. This can be addressed by improving access to accurate and timely information.

False awareness: a person believes that all the information is accessible and that he has it, even when the information that he has may be insufficient, outdated, or misunderstood. In the case of lighting, a person may think he knows all there is to know about lighting because it is a common aspect of his life—not something that he would question. Many people have not experienced true darkness and perceive artificial lighting to be the norm. The team speculates that because artificial lights have become ubiquitous, scientists have not researched their negative impacts at the same rate as their benefits, even though research on their negative impacts indicate potentially serious problems. One possible solution to this problem is disproving people's inclinations to think of lighting as harmless with numerical estimates, such as the International Energy Agency's estimate that global carbon dioxide emissions from lighting are two-thirds that of motor vehicles.

Deliberate unawareness: People do not find an environmental topic to be important, and thus do not seek out more information on the problem. Even when the problem starts to become a topic of interest, people purposefully set aside the facts.  As light pollution starts to become a topic of interest, people may find that changes to address light pollution are too radical and stressful to address. Scientists and practitioners can potentially address this kind of unawareness by framing their arguments in ethical and emotional terms.

Concealed awareness: An actor purposefully omits information and is unable or unwilling to share it with others. This kind of awareness may be motivated by financial issues or a benevolent attempt to secure the public good. Actors may be unable to share information because of a lack of resources or opportunities. For scientists studying lighting, the light-positive paradigm may inhibit scientists from sharing their concerns about light pollution. A critical, open-minded campaign can encourage people to share factual information. Solving problems associated with light pollution can also address other problems, such as carbon emissions. Yet, Lyttimaki's team says that breaking the paradigm that light is always good—essentially changing how people perceive light and darkness—may be a necessary step to bringing light pollution into the public eye. Depictions of light as symbols of progress, modernity, goodness, and godliness are embedded across cultures and time. To effectively understand how to advance environmental information, decision makers and scientists should be aware that people have different reasons for unawareness and non-recognition of environmental problems. Decision-makers can use this as a starting point to develop techniques to solve information problems. https://environment-review.yale.edu/how-and-why-environmental-issues-are-neglected-0


How?

How does air pollution affect our health? Air pollution has a huge impact on our health, reducing quality of live and cutting lives short. In fact, it’s the world’s largest single environmental health risk. It aggravates breathing conditions and increases the risk of asthma attacks leading to more hospital admissions. Prolonged exposure can cause serious medical conditions, such as cancer, heart attacks and strokes. In fact, one in three deaths from strokes, lung cancer and chronic respiratory disease globally are caused by air pollution?

How does air pollution affect the environment?

A great number of air pollution sources are also those of greenhouse gas (GHG) emissions. Greenhouse gases cause the Earth’s heat to be trapped in the atmosphere, which leads to warmer temperatures, exacerbating climate change.

Air pollution can also impact the quality of soil and water, impacting ecosystems and wildlife. 

How can we reduce air pollution?

We need policies and laws in place that protect people’s health and support the shift to cleaner alternatives. At ClientEarth, we’ve taken legal action to combat pollution and fight for clean air in 11 countries across Europe. We’re calling on the UK government to introduce stronger clean air laws to better protect people’s health. We’re also working to design more stringent EU laws that will have an impact in all EU Member States.

When your motorcycle is unattended or not moving, turn off the engine.  Keeping your bike’s engine running when stationary is the quickest route to achieving zero miles per gallon and uses up fuel for nothing. Riding your motorcycle within the legal speed limits not only increases rider safety, but also decreases CO2 emissions and fuel consumption at the same time.  Riding at a speed of 70mph can typically use up to 9% more petrol than travelling at 60mph, increasing to 15% more when compared to a speed of 50mph. https://www.motorcyclescotland.com/reduce-your-motorcycling-carbon-emissions/#:~:text=Fuel%20Management&text=Keeping%20your%20bike's%20engine%20running,consumption%20at%20the%20same%20time.

With children carrying heavier devices (such as laptops and iPads) and books to school, a large number of children suffer from growing deformities that cannot even be corrected, caused as a result of carrying a heavy weight on their backs or rather heavy school bags. Back pain and spinal abnormalities are extremely common in children as young as 10 years. Some of the common issues children face these days are excessive fatigue, muscle and back pain, poor body posture, lumbar pains, neck and shoulder pain, an abnormal curve of the spine etc.

In some cases, children often carry their bag on one shoulder leading to leaning on one side with all the weight. This particularly causes back pain and severe strain to the neck and shoulder. The straps of the backpacks also cause injury by interfering with the nerves and blood circulation.

These issues can cause long-term damage for children growing up. A child’s body is constantly growing and developing, their skeleton gets deformed because of the weight of the backpack and this can cause severe lasting damage. Backpacks cause long-term back problems with poor posture, spine deformity etc. that makes it difficult for the child to function. Identification of the problem is extremely important at an early stage. Heavy backpacks cause back, neck and shoulder pain and this pain becomes worse if kids have sedentary lifestyles.

The health concerns caused due to heavy backpacks can definitely be prevented by early identification of the problem. Parents need to identify signs at an early stage. If the child complaints of back, neck or shoulder pain, leg pain, severe fatigue, or is straining forward when carrying a backpack, get checked with a specialist in order to understand the cause. The overall weight of your child’s back pack should not be more than 10% of your child’s overall weight.

Ferrock has been proven to be five times stronger than traditional concrete. It also has a much higher compression strength and much more flexibility as well.

Excels in Saltwater

When exposed to saltwater, concrete gradually erodes as the sulfates attack the concrete and cause expansions. The presence of chlorides in the seawater then causes the swelling of the concrete to retard, and this leads to erosion.

Ferrock, however, has shown to excel in saltwater environments and become even stronger! This makes Ferrock a perfect alternative to concrete when building

marine-based structures.

Sustainable

Not only is Ferrock CO2 negative and made from 95% recycled materials, but the process in which it’s developed also doesn’t cause any damage to the environment either.

Concrete, however, results in 2.8 billions tonnes of carbon dioxide and is responsible for a tenth of the world’s industrial water usage. A recent study claims there’s more concrete by weight than there is plant matter on Earth today.

Ferrock is currently cheaper, as it is sourced from waste materials.

The leaves of many trees have large surface areas that can act as a natural filter to absorb air pollution and remove heavy metal pollution and other airborne contaminants. https://iopscience.iop.org/article/10.1088/1755-1315/1006/1/012007/pdf#:~:text=Chlorophyll%20is%20a%20natural%20green,various%20environmental%20conditions%20and%20ecosystems.

Air and Soil Pollutants – Trees work nonstop to filter ammonia, sulfur dioxide, nitrogen dioxide, and carbon monoxide from the air and soil.

Without trees, these pollutants would find their way into what crops are left and into the feed of what animals are left, not to mention the air we breathe.

Evapotranspiration – Without trees, the process of evapotranspiration would stop. This is the process of moistening the air which produces more clouds. Evapotranspiration is responsible for maintaining the delicate balance between fertile land and dry desolate desert.

Fewer clouds mean less rain. With less rainfall, fertile land would dry up, fresh water sources would run out or stagnate, and agriculture will begin to fail on a global scale.

Acid Rain – Without trees to remove pollutants, what little rainfall remains would be mostly acidic. All remaining plant life would be crippled.

Global Warming – As the earth’s temperatures rise, the polar ice-caps would melt at an accelerated rate, causing ocean levels to rise and inundate coastal lands and freshwater sources.

As witnessed primarily in the south pole, the ice caps are already receding at an alarming pace, and if this melting isn’t slowed or stopped, it could threaten the survival of all wildlife within that ecosystem.

As the ice melts and causes desalinization in the oceans, weather patterns are subject to erratic change. Off-season snow storms, tsunamis, typhoons, hurricanes, and even blistering summers can all be driven by our raising global thermostat.

Labored Breathing – With CO2 levels on the rise and oxygen levels depleted, people with respiratory and blood problems would be the first to die along with animals unable to cope with the atmospheric changes.

Extinction – Small animals which once depended on trees for food and shelter would be the first to perish. Within a short period, the natural food chain would begin to lose its structure, leaving carnivorous scavengers to likely last the longest.

As temperatures continue to rise, the oxygen levels in the atmosphere decrease, and food sources become even more scarce, the food chain – in its entirety – would eventually break down, leaving every living creature on the planet on a collision coarse with extinction. Including mankind.

Zero-permeability, moisture-resistant, non-combustible cellular glass can withstand a high amount of compression and wide temperature variations.

The manufacturing of partially closed-cell cellular glass transforms melted glass into rigid foam used as pipe insulation.

Manufacturers make cost-effective, thermal, fire, and moisture-resistant open-cell fiberglass insulation material from minute strands of glass in blow-in, loose-fill, rolls, and pre-cut batts. For solidarity, they often use binders or oils.

Closed-cell elastomeric insulation contains elastomers, giving it high elasticity and flexibility.

Phenolic foam offers closed-cell insulation with a high R-value and low thermal conductivity. When paired with a quality vapor barrier, closed-cell phenolic insulation, like Polyguard PolyPhen® phenolic insulation, creates a permeability rating of nearly 0.0, to provide excellent protection against chilled water pipe condensation.

Manufacturing makes fire-resistant phenolic foam in large buns by mixing a surface-acting compound with phenolic resin and solids, resulting in a network of microscopic bubbles that cures into foam insulation for chilled water systems. They ship the insulation to the job site after gluing the vapor barrier jackets to the phenolic insulation sections. During application, the contractor will seal the longitudinal seams of the insulation with mastic, then seal the vapor barrier with self-sealing double-coated tape. 

Thanks for the idea Jacqueline
