Lesson 9 Solid waste management and disposal

Final

Define “waste”

Waste is any material that is unwanted, used up, or discarded.

How is lifestyle related to the quantity of municipal solid waste generated?

Lifestyle affects municipal solid waste because people who consume more, use more packaged and disposable items, or replace goods frequently produce more waste.

Describe examples of source reduction.

• Source reduction means reducing waste before it is made. Examples: using reusable bags and bottles, buying products with less packaging, repairing items instead of replacing them, and choosing long-lasting goods.

Describe the importance of recycling household solid wastes.

Recycling household waste is important because it reduces landfill use, conserves resources, saves energy, lowers pollution, and decreases greenhouse gas emissions.

Describe the various types of composting and the role of composting in solid waste management.

Types of composting:

• Backyard composting – small-scale at home using kitchen and yard waste

• Vermicomposting – using worms to decompose organic waste

• Industrial/large-scale composting – for large amounts of organic waste
  Role: Composting turns organic waste into nutrient-rich soil, reduces landfill waste, and lowers methane emissions.

Describe why electronic waste is becoming a major problem.

Electronic waste (e-waste) is a growing problem because devices are replaced quickly, contain toxic materials like lead and mercury, are hard to recycle, and improper disposal harms the environment and human health.
