Germany-based Wirtgen Group is introducing onsite-recycling technology into China that is designed to cut the waste and carbon emissions associated with demolition sites.
The technology, which has been developed by Wirtgen’s Kleemann GmbH subsidiary, will be showcased in China at Bauma China in Shanghai in November 2010.
Kleemann GmbH recycling plants take demolition waste, demolished concrete, and spoil and convert into high-quality aggregate for the construction industry. By recycling demolition waste onsite the process can dramatically reduce the amount of energy and CO2 emissions required in hauling material away from a demolition site. And instead of demolition waste ending up in land-fill or being used as low grade hardcore it can be used as aggregate for the next building project on that site: thus reducing material costs and the need to extract fresh aggregate by quarrying.
And example of this technology in action is Europe’s largest recycling plant which is located in the vicinity of Amsterdam’s Schiphol Airport. The turnkey plant was designed and built by Kleemann for processing demolition waste, demolished concrete and asphalt into high-quality aggregate for the construction industry. It includes, among other units, Kleemann’s largest impact crusher model SHB 20/160. The recycling plant has a feed capacity of up to 700 tons of material per hour. One year of planning, construction and assembly was needed before the new recycling plant was put into operation. To protect the environment from dust and noise, the entire plant was enclosed with a trapezoidal panel construction.
The recycled product is upgraded with natural sand and cement to a hydraulically bound base layer, and is presently used for soil stabilization at Schiphol Airport.
