Summary of the environmental and social initiatives implemented at the Saitama Plant.

1. Environmental Initiatives

Organic waste processing machine
Organic waste processing machine
Briquetting Machine for Grinding Swarf Reduces Waste
Grinding swarf make up the largest proportion of waste produced by the Saitama Plant. All grinding swarf were previously recycled for use in cement, but the plant has deployed a briquetting machine that compacts and solidifies grinding swarf, enabling the plant to collect and reuse grinding liquid. This change reduced the amount of waste produced and also improved the recyclability of grinding swarf for use as a raw material for steel.
Reduction of Cafeteria Organic Waste and CO2 Emissions
The plant cafeteria produces organic waste, which generates CO2 through incineration. The Saitama Plant has installed a processing machine that uses microbiological action to turn organic waste into fertilizer, enabling the plant to divert more than 10 tonnes of waste from incineration and reduce CO2 emissions.
