Abstract

The amount of effective recovery of waste plastic in Japan was 6,110,000t in 2004. The recycling rate has been increasing from 26% in 1990 to 60% in 2004 . In this research, we have evaluated the recycling techniques from the view points of environmental impact such as CO₂ emissions and amount of oil fuel reduction. For reducing the consumption of plastics and oils and reducing CO₂ emission, material recycle (reproduction), energy recovery (fuel substitution and electric power generation) and chemical modification (fuel substitution and electric power generation) are compared as plastic recycles including cascade processes of utilization. As a result, material recycle is the most effective recycling in the three materials flows, because the material recycle may have few CO₂ emissions while it consumes less crude oil.
