I visited Warm Heart Worldwide in Phrao (Chiang Mai) yesterday with some friends. Here is a picture of Founder Dr Michael Schafer talking about the making of, and benefits of lightweight recycled styrofoam bricks mixed with concrete. The foundation also educates and helps farmers with smokeless recycling of agricultural waste to biochar, among many other charitable activities and micro enterprises. Find out more the organisation here. I/ArtSpeak hopes to go back to do some painting with the children living there.
