1. List and briefly describe at least three (3) types of MSW composting (e.g., household and/or "industrial" types) and distinguish among them (e.g., based on their efficiency, cost-effectiveness, safety, etc.).
2. While MSW composting is generally considered to be very safe for the environment and industrial composting workers, list and briefly describe at least three (3) scenarios in which composting could cause problems for the environment and/or workers exposed to them (hazards and associated risks).
3. Perform your own basic "cost-benefit analysis" for composting, listing and describing at least three (3) benefits and three (3) drawbacks to composting. Overall, do you feel that composting is worth the cost and effort? Please clearly justify your decision (there is no "right" answer, as long as you clearly justify your perspective).
