The Center for Regenerative Design & Collaboration (CRDC) in Costa Rica has started making construction blocks from a combination of recycled plastic and limestone.
The Ecoblock is made from shredded waste that has been shredded after being collected from local rivers in Costa Rica. The finished product is a resin-limestone hybrid which are 2.5.-5 per cent plastic waste and 7-16 per cent waste plastic by volume. The CRDC can produce four million blocks per month which can be used in low-cost housing.
Cement producers have already shown interest in Ecoblock. " The goal of the project is to take a zero waste approach to the resin market," said Don Thomson, CRDC's CEO.
