| Reduction of Combustible Waste |
All Toyota
plants and housing works have continued to maintain zero landfill
waste,* a goal first achieved in December 2000. With regard to
the
initiatives started in FY2001 to reduce combustible waste, in addition
to the central promotion of recycling through measures to ensure
thorough
sorting and reduce generation at the source, Toyota also carried
out measures to reduce sludge, reuse waste oil, extend the life
of coolant
used in the cutting process, and carefully sort combustible waste
paper, etc. This has resulted in a reduction of combustible waste
to 18,200 tons, thus reaching Toyota's goal. Furthermore, with
the
advancement of recycling, the reclamation rate has increased to 97.7%.

the 1995 level |

| Environmental Impact Evaluation of
Recycling |
| In
addition to water and fuel, sludge generated during the painting
process and general wastewater treatment process is comprised
of materials that can be used as raw material for cement. This
recyclable resource can be reused by cement companies. However,
because cement companies are located a long distance from the
plants generating the material, substantial energy is needed
to transport the material. Given this situation, Toyota simulated
the amount of CO2 generated across the entire process from sludge
generation to completion of recycling, including transportation
of the raw material, and evaluated which method of recycling,
thermal recycling or recycling as a resource was most appropriate.
It was consequently determined that thermal recycling was the
most appropriate method, and the sludge is now used as a supplementary
fuel. |
