Instructions: Municipalities make every effort to best use resources and technologies in their management of non-hazardous wastes. It can take
5 five to 10 ten years to construct and to permit a new landfill site. It is to everyone advantage to use the space in a manner that the right types of waste are disposed of and that compaction levels of the waste are high. This is accomplished when easily degradable wastes are composted, when particle sizes are uniform and every opportunity is made to remove recyclable content. The technologies in this chapter are examples of the available tools that engineers use to accomplish these objectives, and this assignment will allow you to further explore this topic.

1) Consider the residential waste components (1st column in Table 2-6 on
page p. 53 in the textbook) and answer the following questions: (Your total response for all parts of this question should be at least 300 words.)
a. What components of mixed municipal solid waste (MSW) are rejected in storage and sent via truck to the landfill?
b. What components pass through the trommel screen? What components are screened out through the trommel screen?
c. What components that passed through the trommel screen are captured in the magnetic separator? What components are sent to the flattener?
d. What components are removed in the sorting step? See Figure 5-38 (on p.
age 225) for additional details.
e. What materials pass through the sorting step and go into the Hammermill shredding operation?
f. What materials are separated in the air classifier operation?
g. How do these processes demonstrate best practices of solid waste management?
