Rotational molding is a globally-used technique for making large plastic objects. Over 3.6 billion pounds of plastic are rotationally molded each year. Unfortunately, the process is energy intensive and uses non-renewable energy sources like natural gas and kerosene. Over 18.4 trillion BTU of fossil fuel is consumed by the rotational molding process, generating over 2.15 billion pounds of greenhouse gasses annually. Rotational molding is an excellent way to make large, life-improving products like water and septic tanks, boats, docks, toys, and much more. Solar Rotational Molding helps this global process cheaper to operate and much more sustainable.
