Title: Ch. 19.2: Reducing Solid Waste


1
Ch. 19.2 Reducing Solid Waste
2
A. Reduce
  • If we produce less waste, we will reduce the
    expense and difficulty of collecting and
    disposing of it.
  • Mostly common sense techniques

3
A. Reduce
  • Buying Less
  • Products with less packaging
  • Not using unnecessary store bags

4
B. Reuse
  • Buying products that last longer
  • Dish towels instead of paper towels
  • The old coke glass bottles that were returned to
    the store, washed, and reused.

5
C. Recycle
  • Also saves energy and resources
  • Ex. 95 less energy is needed to produce aluminum
    from recycled cans than from ore.
  • Ex. 70 less energy for paper

6
C. Recycle
  • A series of steps
  • 1) Items must be collected and sorted
  • 2) Transport to separate facilities
  • 3) Cleaning
  • 4) Breakdown and remade
  • 5) Sold as new products

7
C. Recycle
  • Composting
  • Yard and kitchen waste make up 15 of a
    communitys solid waste
  • All biodegradable
  • After breaking down, compost can be used as
    fertilizer

8
C. Recycle
  • Degradable Plastics
  • Photodegradable plastic made so that when it is
    left in the sun for many weeks, it becomes
    brittle and breaks into pieces.

9
C. Recycle
  • Degradable Plastics
  • Green plastic Made by blending plant sugars
    with a special chemical agent.
  • Requires 20-50 less fossil fuels
  • Degrades within 45 days of being thrown away
    (bacteria break it down)

10
C. Recycle
  • Degradable Plastics
  • Problems These only break down into smaller
    pieces, but these pieces can still remain as long
    as regular plastics.
