2. SOLIDWASTE
Solid waste is the unwanted or useless solid materials
generated from human activities in residential, industrial or
commercial areas.
It may be categorized in three ways. According to its:
Origin: domestic, industrial, commercial, construction, institutional.

•Food Scraps
•News Paper etc.
Industrial Waste
•Metals

•Sludge
•Chemical Solvents
•Paint
•Industrial by-
products etc.
Hazardous Waste
•Automotive Waste
•Pesticides
•Electronics
•Gasoline
•Cleaning Agents
•Radio active wastes
•Batteries etc.
Hazardous waste : Ignitability, Reactivity, Corrosivity, Toxicity.
Different state : solid, liquid, gaseous

8. NEED FOR SOLID & HAZARDOUS WASTE MANAGEMENT
Disposing solid waste is not really a fairly easy job. There are a lot of things that should
be taken into consideration like public health, transportation, proper storage, proper
collection, etc. Failure to abide by rules and protocols might lead to accidents or risk
the health of people in the region.
Recover materials you could still recycle like glass, plastic, and metal.
Minimizes the space essential for landfills. A waste separation plantlessens the level of
garbage that will be disposed to landfills.
To realize about the 3R concept.

9. Keeps the environment clean and fresh.
Protects the health of humans and animals.
Reduces pollution and helps preserve energy.
When hazardous wastes like pesticides, cleaning solvents are mixed up with paper and
other scraps are burned they produce gasses. Thesetoxic gases have a potential of
causing various diseases including cancer.
