Saitama Plant manufactures
recycled materials
from incineration ash.
As a factory of the prefecture’s
“resource recycling model facility”,
we are aiming for carbon neutrality.

Saitama Plant receives 100,000 tons of
incineration ash annually, the largest
scale in the Japan, detoxifies it, and
recycles it as arc sand (artificial sand).
We also recycle non-ferrous metals and
manufacture and sell civil
engineering
materials and aggregates such as
crushed stone and gravel. In addition,
“carbon neutral gas” is used
for natural
gas used in the plant. We are working to
reduce environmental impact and build
a recycling-oriented
society.
