Autoclaved Aerated Concrete is made of naturally occurring material that are found in abundance (lime, sand, water and aerating agent). Furthermore the production of AAC demands relatively small amount of raw material per m3 of product up to a fifth of other traditional building material. Its high resource efficiency results into a low environmental impact in all phases of its life cycle.
During the production no raw material are wasted and all production off cuts are fed back into the production circuit. The manufacture of AAC require less energy that all other masonry products, thereby reducing use of fuels and associated emissions of carbon dioxide (CO2). Industrial water is used and neither water nor steams are released into the environment. Not toxic gases are created in the production process.
Throughout the life cycle of AAC, potential waste is reused or recycled wherever possible to minimise final disposal in landfill. Where AAC waste is sent to landfill, its environment impact is minor since it contains no toxic substances.
