Lesson 6: Waste Reduction and Recycling
Objective: To describe general recycling and reductior topics including its history and the arguments for and against it.
Goals:
Introduction
Terminology:
Reduction - reduction in generation
Reuse - no transformation
Recycle - Use of the material as a source raw material, involves
physical transformation
Recovery - Proess to recover useful material from mixed waste (energy is
an example)
Recyclable materials include - construction wastes, tires, aluminum cans, metals, furnishings and clothing, plastics, yard wastes, glass, animal wastes, paper products

Obstacles to Recycling
Supply and Demand
Price of recovered materials is cyclical, international commodity that responds to international market factors, demand & supply is major factor.
Ingredients for a successful recycling program:
Note: Recycling Will Cost: most programs are subsidized and could not support themselves. But, the $ benefit associated with prolonged landfill life is generally not applied to the balance sheet. Some feel that only recycling cost effective materials can be justified. If it were cost effective, industry would already be doing it.

Paper U.S.
reached a 50.3 percent paper recovery rate in 2003. This shows progress in the recycling sector, as the recovery
goal for 2012 was 55%. Although
the U.S. recovered 50 million tons of paper, allowing 37 percent of all paper
products to be created from recycled paper, the recovery market still faces
major obstacles. Contamination
issues due to single stream collection systems and increasing demand overseas
are just two of the issues paper recovery is facing as o
It has been
recently reported that the recovery rates for aluminum cans has dropped to 44% in
2003 (lowest since 1980). More
than one trillion cans have been thrown in the trash since 1972 o Plastic bottle recycling has dropped to 35.6% o Glass bottle recycling has dropped to 19.1%. Page
