Week 5, Assignment 2, Chapter Questions 5. List some benefits and drawbacks of recycling wastes. What are the major types of materials recycled from municipal waste, and how are they used? The benefits of recycling waste are limitless. Household products alone are a great contributor. Water, paper, plastics, glass, newspapers, milk cartons, cereal boxes, toothpaste boxes, toilet paper and paper towel rolls, etc. all can be recycled into new materials. In addition to basic household items, clothes can be recycled, books, electronic equipment. This does not mean that all items have to go to a facility to be recycled. Clothes, electronics, and anything else can be refurbished, and bought and sold from consumers. In my opinion, there are no drawbacks other than people who do not want to commit to a recycling program. 6. What is e-waste? How is most of it disposed of, and what are some strategies for improving recycling rates? As mentioned in question 5 above without using the proper term, E-waste is an informal name for electronic products that cannot be re-cycled. Computers, televisions, VCR’s, stereos, office equipment, etc. are all common products that can be used, refurbished, or recycled. Most E-waste can be recycled as listed above or by contributing it to different organizations, etc. When the e-waste has hit the end of the road, and is truly waste, the best option would be to have it disposed at a local, credible e-waste facility. Most companies that provide volunteers to collect e-waste are most likely not disposing of it properly. Researching the facility is a good idea

and although there may be a cost or fee, you will know it will be disposed of properly (WiseGeek, n.d.). 10. What are bioremediation and phytoremediation? What are the advantages of these methods? Bioremediation means biological (plant and bacterial) agents are used, phytoremediation uses plants (Phyto = plants.) Both of these methods are used to reduce/clean pollutants. Oil spill, mine discharges, and sewage are a few examples. The advantages of these agents are they are cheaper and use less manpower to produce. Most importantly, they do not release chemicals into the environment. The plants and bacteria use the natural process to break down the pollutants into less harmful compounds. Discussion Questions: 1 and 2. 1. A toxic waste disposal site has been proposed for the Pine Ridge Indian Reservation in South Dakota. Many tribal members oppose this plan, but some favor it because of the jobs and income it will bring to an area with 70 percent unemployment. If local people choose immediate over long-term health, should we object or intervene? I think that we have a right to intervene. Research has shown that in the late 1800s, the U.S. government signed treaties with the Sioux Nation that was an agreement for the federal government to fund medical care on Indian reservations. Although these facilities are under-funded, one has to take into consideration the Casino’s and other privately
