Change:WATER Labs is developing a low-cost, compact and waterless toilet for non-sewered households and communities. Globally, 2.6 billion people lack safe toilet access, and 1 billion defecate openly. Chronic under-investment into sanitation infrastructure means people in many poor and vulnerable communities live with their sewage. With no toilets or pipes, there is no way to flush. The company won Cleantech’s agriculture, water and waste prize. Recently, the company was selected as a finalist in the Cartier Global Businesswomen’s Competition, giving them a chance to win $100,000.
CoolComposites created an additive called CoolFlux for building materials that reduces fire hazard from building insulation. CoolFlux automatically regulates indoor temperature to keep you comfortable. When it gets warm outside CoolFlux traps heat that would otherwise enter your building. At night, it automatically releases that heat and recharges for the next day. The U.S. alone spends more than $20 billion annually on electricity to cool buildings. Globally, more than 500 million tons of carbon dioxide is emitted every year for this purpose. CoolComposites aims to deliver thermal comfort at low cost with its proprietary, MIT-developed inorganic phase change material additive. The company won Cleantech’s Advanced Materials Award.
