The idea of Plastic Waste Pyramid came from Teguh Ostenrik, who was the pioneer of the established of Wisnu Foundation on 1993. Yes, plastic may be recycled into brick, however, some points need to be criticised:
In its first 6 years, Wisnu worked on various environment activities, from awareness to the application of environment management, especially waste. Environment is a living space while the community is its owner. Wisnu then decided to focus its activities on Community Resource Management (SDK), on its way to becoming Desa Hebat (Great Village)!!!
