Aeterra is a sustainability project transforming ash and charcoal waste from public barbeque pits into eco-friendly building materials. By repurposing these by-products, Aeterra reduces waste and promotes sustainability in the BBQ experience. The process enables individuals to create concrete bricks from waste, which can be used to build community features such as gardens, planters, and upgraded BBQ pits. This initiative encourages community participation in the circular economy, fostering environmental responsibility and collaboration. Aeterra aims to create sustainable, accessible spaces and drive greener change within local communities.
