75% of Rwandans live on dirt floors. Along with negative health effects, dirt floors are a blow to a family’s sense of pride and accomplishment. Customary concrete flooring is prohibitively expensive, but luckily there is an alternative: EarthEnable. This scaling social venture provides earthen flooring at ⅓ the cost of traditional concrete, but these earthen floors are difficult to construct.
That’s where the sand.trifuge comes in. By adapting “the paperfuge” — a novel take on centrifugation — we have created a scientific test that can ensure the quality of EarthEnable’s most variable input, sand. In a low-cost and time-efficient manner, our device guarantees this novel business the delivery of a transformative product.
