It is Keymark's policy and responsibility to be environmentally friendly to the communities where we manufacture as well as the areas in which our extrusions are installed and maintained. We are continually focused on improving our aluminum extrusion manufacturing operations to reduce waste and maximize efficiency. The following are areas in which we demonstrate our dedication and efforts to eliminate those wastes, control pollution, and focus on recycling/recovery.
Keymark Corporation extrudes over eighty-percent of its weekly production lbs. from prime aluminum billet produced internally at our secondary casting facility. Over 38% of the aluminum billet is composed from recycled internal or outside purchased aluminum scrap. Documentation may be provided to help ensure the requirements of the U.S. Green Building Council.
Dross, which is a waste by-product of the casting process (40,000/lbs. weekly), is sent to an aluminum smelter for continuous recycled use.
Due to the recent upgrade to the regenerative burners in the melting unit, this upgrade resulted in a reduction of 171.8 million cubic feet annually of natural gas savings. Also as a result of this upgrade, Keymark reduced 2.83 tons of carbon monoxide emissions annually.
