Büscher builds a brand new house out of 75% recycled concrete and demolition waste
Published 12/9, 2023 at 09:56The German company Büscher is said to be the first company in the world to have built a complete house out of 75% recycled construction and demolition waste, with the load bearing and non-load-bearing interior wall elements being made of 100% recycled aggregates. Appropriately, the sustainable house was built using sustainable production equipment.
The Büscher site is also equipped with solar panels delivering up to 323kW/h of renewable electricity which is used to power concrete production as well as the Keestrack R3e ‘Zero’ impact crusher and the K4e Zero screen. Both Keestrack machines are fully electrically powered by renewable energy and do not have a combustion engine onboard. As the electric motors drive most of the mobile crushing and screening equipment and power some necessary hydraulics systems, both Keestrack machines run with zero CO2 emissions.
When plugged in to the grid, like at the Büscher recycling site, where they use renewable energy using photovoltaic solar panels, the R3 and K4 are producing zero carbon emissions. The energy cost will be approximately 152kWh. Operational and maintenance costs are said to also decrease drastically as there is no engine on board to maintain.
