High Efficiency Waste Powered Generation System in Cooperation with the Local Community
Winner
Toyota Motor Corporation |
This is a high efficiency waste powered cogeneration system
utilizing solid refuse derived fuel (RDF) made from waste collected
from Toyota's own offices and factories as well as local governments
and businesses.
Recycled use of incinerated ash for the automobile manufacture,
and production and utilization of RDF was highly evaluated. |

Features of Equipment, Systems and Facilities
Reduction of environmental impact by cooperating with
local community
Toyota Motor Corporation uses RDF for fuel of their own
power generation plant. The RDF was produced by waste collected
by neighboring local governments and businesses. Toyota
purchases the RDF at a certain rate.
Highly efficient use of energy
The maximum power output of the generation system is 16,000
kW. As the exhaust steam can be used as a heating source
in the plant, the total heat efficiency achieved 85%. This
is the largest thermal recycle system in Japan. Annually,
about 50,000 t of RDF production is available from industrial
waste and general waste, which is equivalent to a saving
of 18,000 kl of kerosene.
Reduction of environmental load material discharge
Toyota makes their utmost effort to reduce environmental
load material including dioxin, NOx, and SOx. Also, Toyota
has developed a technology to effectively utilize incineration
ash as resin filler at their automobile factory.
