7.3.2 Waste Management

• What is the primary purpose of waste management?

  Reduce environmental impact
• Incineration of waste can recover energy but produces air pollution


  True
• Match the waste management method with its description:

  Landfill ↔️ Burying waste in designated sites

  Incineration ↔️ Burning waste to reduce volume

  Recycling ↔️ Reprocessing waste into new products

  Composting ↔️ Decomposing organic waste
• Landfills are effective at preventing soil and groundwater pollution

  False
• Order the following sources of waste from most common to least common in terms of volume:

  1️⃣ Domestic

  2️⃣ Industrial

  3️⃣ Commercial

  4️⃣ Agricultural
• Burning waste to reduce its volume is called incineration
• Why is recycling an important waste management method?

  Reduces pollution and conserves resources
• Landfills can lead to soil and groundwater pollution if not managed properly


  True
• Incineration of waste can recover energy but produces air pollution and toxic ash.


  True
• What type of waste is typically composted?

  Organic waste
• Recycling reduces the reliance on extracting raw materials
• Recycling helps reduce environmental pollution by diverting waste from landfills and incinerators.


  True
• Composting organic waste prevents the release of methane, a potent greenhouse gas
• Match the waste management method with its environmental impact:

  Landfill ↔️ Can lead to pollution

  Incineration ↔️ Produces air pollution

  Recycling ↔️ Reprocesses materials

  Composting ↔️ Decomposes organic waste
• Effective waste management conserves natural resources by recycling and reusing materials.


  True
• What is one example of industrial waste?

  Chemical waste
• Recycling involves reprocessing waste materials into new products.

  True
• Recycling reduces the amount of waste sent to landfills.


  True
• What is an integrated waste management approach?

  Using multiple waste methods
• Recycling reduces environmental pollution by diverting waste from landfills and incinerators
• Compost improves soil fertility and structure.


  True
• Match the waste management method with its description:

  Landfill ↔️ Buries waste, can lead to pollution

  Incineration ↔️ Reduces volume but produces air pollution

  Recycling ↔️ Reprocesses materials into new products

  Composting ↔️ Decomposes organic waste into nutrient-rich soil
• Decomposing waste in landfills releases methane, a potent greenhouse gas.


  True
• Order the steps in effective landfill management:

  1️⃣ Lining the landfill with impermeable materials

  2️⃣ Collecting leachate
• Landfills are effective for large waste volumes but can cause soil pollution.


  True
• What is the primary goal of an integrated waste management strategy?

  Protecting ecosystems
• Burying waste in designated sites is called landfill
• What does recycling involve in waste management?

  Reprocessing waste into new products
• Effective waste management reduces pollution and environmental damage
• What type of waste is commonly used in composting?

  Organic waste
• What is an example of domestic waste?

  Household garbage
• Recycling conserves natural resources


  True
• What is the end product of composting organic waste?

  Fertilizer
• Effective waste management helps conserve natural resources
• What is the main drawback of using landfills for waste disposal?

  Soil and groundwater pollution
• Recycling conserves natural resources
• An integrated waste management approach often involves using multiple methods to reduce environmental impact.


  True
• What is one benefit of recycling in terms of natural resources?

  Conserves finite resources
• Steps involved in the composting process:

  1️⃣ Collect organic waste

  2️⃣ Decompose waste into compost

  3️⃣ Use compost as soil amendment
• What is the end product of composting organic waste?

  Compost
