Normandeau is committed to environmental stewardship in our business practices. We have lowered our consumption footprint by increasing energy efficiency in buildings, purchasing cleaner-running engines for our vessels, implementing reuse and recycling programs, using products made from recycled materials, and reducing our waste stream.
