Base Zero’s materials database search engine and listing site introduces and compares alternative materials on an industry-by-industry basis, material by material. Each traditionally used standard material is compared with a more sustainable alternative in terms of standard material properties, strengths, stresses, capabilities, limitations, and embedded energy. For example it may be possible for a manufacturer to use a plant-based or recycled/waste-sourced plastic or metal for an application instead of a straight-from-petroleum PVC or PET, or raw aluminium.
