Assignment

Instructions: This assignment will allow you to understand the volume of non-hazardous waste that is generated by small businesses and residential homes. A portion will go to the landfill, and a portion will go into recycling programs for reuse or for repurposing. Being able to calculate these are is important for estimating the size of facilities handling this wastes and of the equipment and personnel required to collect and transport these wastes from point of generation to final disposition.

The specified word count is given for each question. At a minimum, you must use your textbook as a resource for these questions. Other sources may be used as needed. All material from outside sources (including your textbook) must be cited and referenced in APA format. Include a reference list after each question.

1) A front loader garbage truck of 40 cu. yd. collects municipal solid waste each week from dumpster bins of apartment complexes located throughout the city. The waste in the truck is compacted to 750 pounds/cu. yd. The uncompacted waste in the dumpster bin is 175 pounds / cu. yd. (For all parts of this question, be sure to show all of your work.)

a) How many full dumpster bins with a 3 cu. yd. capacity can be placed into the garbage truck?

b) If the apartment complex has a mandatory recycling program and each person places only 4 pounds/day of trash into the dumpster bin, how many people can the garbage truck serve before it is full?

c) If the apartment complex has a mandatory recycling program and each person places only 3.5 pounds/day of trash into the dumpster bin, how many more people can the garbage truck serve before it is full?

2) A municipal government has hired you to help them with its recycle program. Using the information in Table 2--13 on page p. 65 of the textbook, propose three key areas where you would focus the municipal program and give your reasons for your proposals. In your answer, be sure to discuss how this program would affect the population of the municipality. (Your total response for all parts of this question should be at least 200 words.)

3) A mobile phone is comprised of 15.5% of copper, and nickel and silver comprise 2.5% as broken down on pg.p. 66, Fig, 2--15. These three metals represent 83% of the potential toxicity that the components of the phone can exert on the environment. Describe how copper is toxic to the environment, and how this can affect the residents of an area. (Your total response for all parts of this question should be at least 200 words.)

4) Describe the elements of the Integrated Solid Waste Management program. Give a detailed discussion and explanation as to which element has the greatest potential to impact affect the success of the program. What science and engineering principles are involved in this program? (Your total response for all parts of this question should be at least 300 words.)
