GradeBuddy is best used as a supplement to your own notes, not as a substitute.Current LectureI. Solid Waste- Amount determined by our lifestyle- The disposable decades – throwaway life-style- Considered a right by many- Considered a duty by others- 50’s and 60’s were the disposable decadesII. United States- Near 200 million tons of municipal solid waste (garbage) every year- 1.9 (1.5) kilograms or 4.2 (3.3) pounds per person per day- 80% increase since 1960- U.S. has 4.6% of the world population but creates 33% of the wasteIII. The Problem- Too much garbage and not enough places to put itIV. The Old Sites- Full- Filling- Environmentally unacceptable – River, Wetland, Ocean- “Out-of-Town”V. Methods of Disposal- Dump it – Landfills- Burn it – Incineration- Convert it – Recycle- Don’t make as much in the first place – source reductionVI. Incineration- Air Pollution- Disposal of Ash- Cost and Siting- Doesn’t encourage reductionVII. Mass Burn- Waste to Power – generates electricity- Definition for incinerationVIII. Landfills- Groundwater contamination- Methane production- Citizen concerns- NIMBY – Not in My Back Yard- Political concerns – NIMEY – Not in My Election Year- Economic – over 1 million per hectare for new dumpIX. Recycling- 30 % in North America now – was 10% in 95- Our goal was 25% by 2000- Canada 50% by 2000- Japan was 45% in 1995 X. Problem- Technology- Economics – Supply from recyclers and demand from consumers- New products developed- It is an individual thingXI. Paper or Plastic- Using your own bag is more efficient XII. Source Reduction- Reduce volume of packaging- Reduce weight of packaging- Concentrates- Economic issueXIII. 3 R’s- Reduce (highest priority)- Reuse- Recycle- In this
