3. In 2008, Americans generated 250 million tons of nonhazardous municipal solid waste. Of that waste, • 54.2 percent was discarded
• 33.2 percent was recovered
• 12.6 percent was burned with energy recovery at 590 kWh of electricity per ton
Fill in the table to answer the following:
• How many tons were discarded, and what is the method by which solid waste is discarded?
• How many tons were recovered, and what are the methods of recovery?
• How many tons were burned, what was the method for producing electricity, and how much electricity was generated?
Discuss the positive and negative environmental impacts of eliminating one of the three endpoints.
