While recycling trash is preferable – its quite common to simply chuck refuse into the dump that
creates tons of by-products that end up making their way to the landfill. Fortunately, Professors Rahul Ralegaonkar and Sachin Mandavgane of the Visvesvaraya National Institute of Technology in India (VNIT) have developed a way to create paper bricks from recycled waste. Made from 90% recycled paper mill waste (RPMW) and 10% cement, the mixture is mechanically mixed and pressed into molds and then cured in the sun. This brilliant recycled building material is a low-cost means of eking more efficiency out of an already good practice.
