WHAT IS WASTE ?
Waste are undesirable or unusable materials.
It is any material which is disposed off after essential utilize and ( it means that waste is any material which we throw away after we have used it ).
Examples : –
- Municipal Solid Waste ( from houses and its nearby areas )
- Wastewater ( such as sewage )
- Surface overflow
- Radioactive waste
- E-waste and so on.
TYPES OF WASTE
The types of solid waste are : –
On the basis of source :
1. Municipal Solid Waste ( It includes household waste , commercial waste ) .
2. Hazardous Waste or Dangerous Waste ( includes various mechanical waste ).
3. Biomedical Waste ( It includes waste from medical sources )
4. Special Waste ( This covers radioactive waste and E-waste ).
INFLUENCE OF WASTE ON ENVIRONMENT
The harmful effects of improper waste management systems is observed :
- Water Contamination
- Human Damage
- Soil Contamination
- Climate Contamination
- Air Contamination
- Disturbance in animal and marine life
1. This comes from sources like Landfills, back streets , open sewers etc .
These are the places from where : –
- Waste collects and strengthens and
- Leaves us with headaches .
2. Things are made worse with rainfall (acid rain ) which mixes up to generate toxic liquid substances which saturates the water channel and ends up in the nearby water bodies.
Consider the majority of human population for whom we do not see any scientific waste management system.
Near the landfills , the place is highly contaminated due to excess of waste products collected out there .
So the people who are at great risk from these waste materials are :
- Youngsters and individuals who live near such houses.
- Waste transfer laborers.
- Employees who come in contact with such waste materials.
- Plastic bottles in the end breakdown to discharge DEHA ( diethyl hydroxlamine ) , DIETHYL AMINE , a cancer causing agent which harms our reproductive capabilities , causes liver problems and weight reduction issues.
- This is because these chemicals get mixed with plants nutrients through soil and affects us when we consume them.
- DEHA saturates the surrounding areas of the soil , water bodies and humans , and harms the animal and plant life dependent on it.
- The ink from the paper is not originally reused by the Earth as it contaminates the soil.
#TYPES OF WASTE MATERIALS
- Biodegradable Waste
- Non-Biodegradable Waste
Non -Biodegradable Waste usually cause much more impact than Biodegradable waste.
This is because it takes a very long time to degrade the substances.
WHAT ARE THE HEALTH ISSUES ?
- Respiratory Problems
- Visibility Problems
- Skin Irritation
- Blood Infections ( when we stay nearby to these areas from where the waste gets segregated ).
- Therefore bleach , oil or acid are given special attention.
- On the occasions, papers and plastics are burned at landfill, which causes Air Pollution and contributes for Ozone layer depletion.
- Methane gas adds to it as well.
- Chemicals such as DIOXIN out there, air has been proven to have harmful effects on us.
HARM TOWARDS ANIMAL AND MARINE LIFE
Despite of certain strict rules , we keep doing dumping of garbage, raw and untreated garbage.
Any animal or plant life coming in contact gets impacted in a very harmful way.
The unavoidable development of Algal Bloom chokes out marine life such as fish.
HOW DOES IT FUNCTION ?
Waste is dumped into the ground and absorbed by the soil and ground water.
It contaminates the ground water on which we grow food and used by us and animals too.
The waste in marine life kills Fish.
Diseases carrying mosquito now spread sickness among the living population.
WHAT IS SOLID WASTE ?
Solid waste are any discarded or disposed off materials.
- Waste tires
- Scrap Metal
- Furniture and Toys
- Appliances and Vehicles
- Oil and anti – freeze
- Empty aerosol cans , paint cans
- Construction and demolition debris , Asbestos
TYPES OF SOLID WASTE
There are many types of solid waste depending on their source :
2. INDUSTRIAL WASTE ( Generally classified as hazardous waste or dangerous waste )
3. BIOMEDICAL WASTE ( Generally classified as Hospital waste or Infectious waste ).
Municipal solid waste consists of household waste , construction and waste from streets.
With urbanization and change in lifestyle and food habits , the amount of Municipal solid waste has been increasing rapidly.
In India , some municipal areas have banned the use of plastics and they got success.
Many large cities , shops have started using Reusable and Biodegradable bags.
Industrial waste and hospital waste are considered hazardous as they consists of toxic substances.
Hazardous waste are very dangerous to humans , animals and plants.
Examples :- Gases
Household waste expressed as hazardous waste includes many waste materials and some of them include old batteries , shoe polish , paint tins , old medicines and medicine bottles and so on.
Hospital waste is the waste disturbed by chemicals and is considered hazardous.
Some of the chemicals are :-
- Formaldehyde and
Mercury which is used in thermometers.
WAYS TO DEPLOY WASTE
Now you know about What is solid waste ?.
Methods of solid waste disposal and management are :-
- Open Burning ( Not an ideal method in the present day context )
- Dumping into the sea ( Not environment friendly )
- Sanitary Landfills ( Simple , Cheap and effective )
- Incineration ( Suited in crowded cities where sites for land filling are not available )
- Composting ( Ideal for Biodegradable waste from kitchens , hotels etc. )
