It is the clear responsibility of all research workers to ensure the safe and correct disposal of all wastes produced in the course of their work. Improper and irresponsible disposal of chemical wastes down drains, to the Local Authority refuse collection, or into the atmosphere is forbidden by law. All waste suitable for the Local Authority refuse collection, except recyclable paper and glass, is termed 'controlled waste'. Items in this category which includes dirty paper, plastic, rubber and wood, should generally be placed in the waste bins available in each laboratory and will be collected by the cleaners. However, each laboratory must also have a container for certain items which are not allowed to be put in the normal waste bins. In this special controlled waste container should be put:- all broken laboratory glassware, any sharp objects of metal or glass, all fine powders (preferably inside a bottle or jar) and dirty sample tubes or other items lightly contaminated with chemicals (but not any syringes or needles).

hazardous lab waste is any solid liquid or gaseous material that has a hazardous symbol on it or is named as hazardous waste.

rules to manage waste:
look for ways to minimise waste produced
only use appropriate containers for the waste
keep waste containers closed
label all contents and what the hazard is

There are three main types of waste that you need to know about so you can put the right kind in the right bin for our collection teams:

Food and garden waste (green service)

Mixed dry recycling (blue service)

Non-recyclable waste (black service

Hazardous chemicals;
Chemical wastes go to the chemical waste procedure
Clinical wastes go to the clinical waste procedure
Radioactive wastes go to the radioactive waste procedure

If the substance is unknown they must segregate it from other waste

Some waste such as; packaging for lab consumables, paper, hand towels, pipette tip boxes, cardboard, others dry non-hazardous laboratory wastes are all recyclable

Proper waste disposal is critical due to the fact that certain types of wastes can be hazardous and can contaminate the environment if not handled properly. These types of waste also have the potential to cause disease or get into water supplies
Some waste will eventually rot, but not all, and in the process it may smell or generate methane gas, which is explosive and contributes to the greenhouse effect.
Incinerating waste also causes problems, because plastics tend to produce toxic substances, such as dioxins, when they are burnt. Gases from incineration may cause air pollution and contribute to acid rain, while the ash from incinerators may contain heavy metals and other toxins.

Wash down drains with excess water:
Concentrated and dilute acids and alkalis
Harmless soluble inorganic salts (including all drying agents such as CaCl2, MgSO4, Na2SO4, P2O5)
Alcohols containing salts (e.g. from destroying sodium)
Hypochlorite solutions from destroying cyanids, phosphines, etc.
Fine (tlc grade) silica and alumina

- wash down drains with excess water.
- incinerate materials that can be burned without causing damage.
- controlled laboratory waste bins. like tattoo shops they have sharp bins.
- waste has special collection, different from house hold waste.
- the same happens to glass.

Incineration (Solvent Waste collection)

all organic solvents including water miscible ones

soluble organic waste including most organic solids

paraffin and mineral oil (from oil baths and pumps)

All labs must have a bin for glass recycling.

Bio-hazard/Sharps Disposal - Syringes and Needles
"Sharps" contaminated with biologically hazardous materials must be collected in special containers to be sent for incineration. It is also required, at the request of Fife Council, that all syringes and needles of any type should be disposed of by the same route. No syringes or needles must ever by put in a laboratory waste bin or controlled waste container.

Packaging, labeling, storage are the three requirements for disposing chemical waste.

For packaging, chemical liquid waste containers should only be filled up to 75% capacity to allow for vapor and to reduce potential spills which could occur from moving overfilled containers.

Label all containers with the group name from the chemical waste category and an itemized list of the contents.

When storing chemical wastes, the containers must be in good condition and should remain closed unless waste is being added.

Waste management to reduce its environmental impact: pollution prevention and source reduction; reuse or redistribution of unwanted, surplus materials; treatment, reclamation, and recycling of materials within the waste; and disposal through incineration, treatment, or land burial.

Each service needs to have policies and procedures to help them guide the actions of all individuals involved in the service. They ensure and endorse the well-being of all families, children, staff, volunteers and everyone who is connected to the service.

It is irresponsible to dispose waste down the drains as they could be toxic chemicals. Drains should be washed down at all time with water  and that materials on  the red list  should not be tipped down thew drains as they could be toxic .

There needs to be a controlled waste bin as not  all waste the can  go in the general waste bin.

Not all glass can go in the waste  only clean glass can go in glass recycling as they have not come in to contact with chemicals.

The work surface must be cleaned along with your hands if their are any spills on them and to ensure that any powder chemicals are put into proper storage areas or waste bins.

Also, For each chemical waste produced, instruct students to appropriately dispose of the chemicals including the disposal of a substance in a disposable container ( if a solid; magnesium sulfate)or down a drain (If a liquid; sulfur oxide)
To dispose of laboratory liquids chemical  waste  the correct procedure must be followed. For acid you must do this:

1. Obtain a container that will not deteriorate when the acid is added to it.

2. Place the empty container into an ice bucket.

3. Dilute the acid with water.

4. Test the pH of the acid with pH paper or litmus paper.

5. Make a neutralizing solution.

6. Neutralize the dilute acid.

7. Test the pH frequently.

This Procedure has to be done so there are no accidents during the cleaning process and it should be communicated with any lab partner so that both people can follow the procedure.
These have to be done for the safety of the person performing the experiment doesn't receive a serious injury, or the people around them don't receive a dangerous injury and that the equipment isn't broken and so it can be used again for further experiments.
Then to dispose of Solid Chemicals you should put it into a storage container or the waste bin specifically made for chemicals substances only.

Most procedures are written in the Aldrich Handbook.
To dispose of most acids and alkalis you need to rinse it down the sink with excess water.
Organic waste needs to be incinerated.
Most places have waste bins that are for controlled waste.
Most hazardous chemicals like poisons need to be put into a separate container and are then most likely to be picked up and taken away.
For sharp objects and needles there needs to be a bin that no one can but their hand into for safety and are then collected by a company to dispose of them properly.
Glass should always have a separate box so that it can be disposed of properly.

All of the waste disposal procedures needs to be followed to insure everyones safety and to make sure that there is as little impact as possible on the environment. Some hazardous chemicals (if wrongly disposed of) can have a serious impact on the environment.
