India: Goa Waste Management Corporation (GWMC) has obtained a 20-year patent for its Laterite-Based Concrete Block. The company produces the block using up to 100% construction and demolition materials. Norway-based research organisation SINTEF was technical partner for the development. GWMC plans to licence the technology to producers.
GWMC said "This invention will lead to a significantly cleaner local environment, as construction and demolition materials are a major waste stream in Goa. The groundwater resources in Goa will also have a higher protection against unwanted leaching."
