TREATMENT PLANTS AND SITES • Plastics, metal parts, sludge etc. AGRICULTURE • Spoiled food, pesticide containers and other hazardous materials. BIOMEDICAL • Syringes, bandages, used gloves, drugs, paper, plastics, food wastes and chemicals.
- 7. SOLID WASTE MANAGEMENT The process of collection, transfer, recovery and safe disposal of solid wastes is called solid waste management.
- 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 plant lessens 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. These toxic gases have a potential of causing various diseases including cancer.
