LANDFILL UNIT 2

What are the two fundamental objectives of solid waste management?

• To minimize waste and to recycle materials.

• To minimize waste and to manage the waste still produced.

• To incinerate waste and to reduce landfill use.

• To manage hazardous waste and to promote composting.

What are the main components of the 3R approach in solid waste management?

• Reduce, Reuse, Recycle

• Reduce, Refuse, Recycle

• Reuse, Recycle, Recover

• Reduce, Reuse, Recover

What are the emerging limitations in solid waste management?

• Constraints in energy and raw materials, impacting waste processing and disposal.

• Increased recycling rates leading to less waste.

• Advancements in waste-to-energy technologies.

• Government regulations promoting waste reduction.

What are some methods of waste transformation?

• Shredding, size separation, volume reduction through thermal treatment, and encapsulation to reduce toxicity.

• Composting, recycling, incineration, and landfilling.

• Bioremediation, phytoremediation, anaerobic digestion, and chemical treatment.

• Sorting, washing, drying, and packaging.

What historical methods were commonly used for solid waste disposal at the turn of the century?

• Dumping on land

• Incineration

• Composting

• Feeding to chickens

What is Solid Waste Management (SWM)?

• SWM is a system for the disposal of liquid waste only.

• SWM is a system associated with the control of generation, storage, collection, transfer, transport, processing, and disposal of solid wastes in a manner that adheres to public health, economic, engineering, conservation, aesthetic, and environmental considerations.

• SWM refers to the recycling of electronic waste exclusively.

• SWM is a method for managing hazardous waste in industrial settings.

What is the impact of plastics on solid waste generation?

• Plastics reduce food waste at home but increase waste at agricultural processing plants.

• Plastics have no impact on solid waste generation.

• Plastics completely eliminate solid waste generation.

• Plastics only increase food waste at home.

What are the steps involved in the transfer and transport of solid wastes?

• 1. Transfer waste from smaller collection vehicles to larger transport equipment. 2. Transport the wastes to processing or disposal sites.

• 1. Collect waste from households and businesses. 2. Sort waste into recyclable and non-recyclable materials.

• 1. Incinerate waste on-site. 2. Bury waste in landfills without processing.

• 1. Store waste in temporary containers. 2. Leave waste unattended until collection day.

What is the significance of the industrial revolution in waste generation?

• It led to a decrease in waste generation due to better recycling methods.

• It marked the beginning of a technological society, leading to increased waste generation alongside the benefits of technology.

• It had no impact on waste generation as society remained agrarian.

• It resulted in the complete elimination of waste through advanced technologies.

What is the role of resource recovery in solid waste management?

• Resource recovery involves incinerating waste to reduce its volume.

• Resource recovery involves reclaiming materials from waste for reuse, recycling, or energy recovery, thus minimizing the amount of waste that needs to be disposed of.

• Resource recovery is the process of burying waste in landfills to prevent pollution.

• Resource recovery focuses on the transportation of waste to different locations.
