GREGOIRE put into force an environment policy as follows : 

Water

Reject "0" ensured through daily controls of water consumption.

Rejects

None. No waste water station, therefore no paper mud.

Air

The steamgenerators at GREGOIRE run with natural gas to minimize the rejects in the atmosphere.

Noise

Two tests yearly, to control if the allowed limits are respected

Ground and
underground

All chemicals are stored on retention in order to avoid any spillage
