Understanding Waste Management

What are the main types of waste?

• Municipal solid waste, hazardous waste, industrial waste, biomedical waste, electronic waste

• Construction waste

• Organic waste

• Food waste

Name one example of hazardous waste.

• Used motor oil

• Food waste

• Plastic bottles

• Paper towels

What is the purpose of waste management?

• The purpose of waste management is to protect human health and the environment by managing waste effectively.

• To increase waste production for economic growth.

• To encourage littering in public spaces.

• To promote the use of non-biodegradable materials.

List two waste management techniques.

• Hazardous waste disposal, E-waste recycling

• Landfilling, Incineration

• Recycling, Composting

• Open burning, Ocean dumping

What is composting?

• Composting involves burying organic waste underground.

• Composting is a method of burning waste materials.

• Composting is the natural process of recycling organic matter, such as food and yard waste, into a valuable fertilizer.

• Composting is the process of creating synthetic fertilizers.

How does recycling help the environment?

• Recycling has no impact on resource conservation.

• Recycling helps the environment by conserving resources, reducing pollution, and minimizing waste.

• Recycling increases waste production.

• Recycling contributes to higher pollution levels.

What materials can be recycled?

• Paper, cardboard, glass, metals, plastics, electronics

• Food waste

• Batteries

• Textiles

Describe the recycling process for paper.

• Burying the paper in landfills

• The recycling process for paper involves collection, sorting, shredding, pulping, cleaning, de-inking, drying, and re-manufacturing into new paper products.

• Burning the paper waste to generate energy

• Mixing paper with plastic for disposal

What is the difference between biodegradable and non-biodegradable waste?

• Biodegradable waste decomposes naturally; non-biodegradable waste does not.

• Biodegradable waste is made from plastic; non-biodegradable waste is organic.

• Biodegradable waste is always toxic; non-biodegradable waste is safe.

• Both types of waste can decompose in landfills.

Give an example of a biodegradable material.

• Styrofoam

• Polylactic acid (PLA)

• Polyethylene

• Glass
