Answer:
BACKGROUND: Compared with creating an aluminum can from raw materials, recycling one soda can results in 85% less air pollution and 97% less water pollution and uses 90% less energy.
New York State, like several other states, has a bottle deposit law. The bottle bill gives people an incentive to keep litter off the streets and bottles and cans out of the landfill. For each deposit container you bring to the store you receive 5 cents and the container usually is recycled by the company. In other states, cans may be taken to recycling centers which pay by the pound. The following exercise takes place in such a recycling center.
PROCEDURE: Discuss the advantages of recycling aluminum, and have the students complete the problems on the following page.
Answers:
1. 24 cans/lb x 15,000 lb/trailer = 360,000 cans/trailer
2. Answer will depend on your price per can or per pound. For example, if price is 60 cents per pound: $0.60/lb x 15,000 lb = $9,000
3. 15,000 lbs/trailer / 30 lbs/collector = 500 can collectors/trailer
4. 15,000 lbs/trailer / 800 lbs/bale = 18 complete bales (and 3/4 of another bale)/trailer
5. 24 cans/lb x 800 lb/bale = 19,200 cans / bale
6. 100 bales/boxcar x 800 lbs/bale = 80,000 lb. cans / boxcar
7. 100 bales/boxcar x 19,200 cans/bale = 1,920,000 cans / boxcar
8. Answer will depend on your price per can or per pound. For example, if price is 60 cents per pound: $0.60/lb x 80,000 lb/boxcar = $48,000/boxcar
