In a world increasingly concerned with questions of energy production and raw material shortages, this video demonstrates an innovative and sustainable solution to material production; a microbially induced casting procedure, which presents the bacterium bacillus pasterurii as a method of cementing sand using minerals as binding agents.
The process forms mineral composites at biological temperatures. The biomaterial is structurally comparable to concrete, yet the production of the biomaterial produces no greenhouse gases. Concrete is responsible for 5 % of the worlds manmade C02 emissions. This process illustrates the sustainable potential of an alternative means to production.
