Environmental Conservation in Japan
We are making further efforts toward zero emission and toward reducing CO2 emission
To secure a workplace with less environmental burden, we are aggressively working on waste reduction, recycling, pollution prevention, resource conservation, CO2 emission reduction, etc.
Soil and Water Contamination Prevention
Alpine has carefully implemented comprehensive risk control to prevent soil and water contamination. Oil-retention walls around heavy oil tanks prevent the outflow of oil onto the ground. Yearly employee training programs provide for contingencies to minimize risk.
For prevention of water contamination, we are implementing, on a daily basis, strict checking of water purification tanks and improving their functions. Also we have introduced a system to constantly monitor discharged water quality.
In 2006, we conducted renovation works to further improve treatment capacity of the water purification tanks.
