What are the three main waste management techniques?

• Collection, Transportation, Disposal

• Sorting, Processing, Treatment

• Incineration, Landfilling, Composting

• Reduction, Reuse, Recycling

Describe the process of aerobic composting.

• Aerobic composting involves burning organic waste to produce energy.

• Aerobic composting requires the use of chemical fertilizers to enhance decomposition.

• Aerobic composting is the process of decomposing organic matter with the help of oxygen, using microorganisms to break down materials into compost.

• Aerobic composting is the process of freezing organic matter to preserve it.

What is the purpose of a leachate collection system in landfills?

• To provide a habitat for local wildlife.

• To collect and manage leachate to prevent environmental contamination.

• To increase the volume of waste in the landfill.

• To enhance the aesthetic appeal of the landfill.

List two advantages of using anaerobic composting.

• Requires more water for the process.

• Increases the volume of waste produced.

• 1. Reduces odors and greenhouse gas emissions. 2. Faster breakdown of organic materials.

• Slower decomposition of materials.

What factors should be considered in landfill site selection?

• Proximity to major highways

• Historical significance of the land

• Aesthetic appeal of the landscape

• Factors to consider in landfill site selection include proximity to populations, geological stability, hydrology, soil characteristics, land use compatibility, environmental impact, accessibility, and community acceptance.

Explain the concept of waste-to-energy in waste management.

• Waste-to-energy is the process of incinerating waste without energy recovery.

• Waste-to-energy is a process that converts waste materials into usable energy, reducing landfill use and generating electricity or heat.

• Waste-to-energy is a method of recycling plastics into new products.

• Waste-to-energy involves composting organic waste to enrich soil.

What materials are typically suitable for composting?

• Plastic waste

• Meat and dairy products

• Chemical fertilizers

• Suitable materials for composting include fruit and vegetable scraps, coffee grounds, grass clippings, dry leaves, straw, and cardboard.

How does a landfill gas collection system work?

• It relies on natural gas to power the landfill operations.

• A landfill gas collection system captures methane and carbon dioxide from decomposing waste using wells and pipes.

• It incinerates waste to produce electricity.

• It uses solar panels to convert waste into energy.

What is the role of cover material in landfill management?

• Cover material is primarily for aesthetic purposes.

• Cover material helps control odors, pests, and fires, stabilizes waste, and promotes decomposition.

• Cover material is used to increase landfill size.

• Cover material prevents all types of waste from decomposing.

Describe the importance of public education in waste management practices.

• Public education only benefits government agencies.

• Public education is essential for promoting awareness, encouraging sustainable behaviors, and improving participation in waste management practices.

• Public education is not necessary for waste management.

• Public education can lead to increased waste generation.
