Recycling can play a significant role in promoting environmental health, building health and building biology. Building biology is a science that examines the way our built environments impact our health and how we can design healthy buildings 1. Recycling can help reduce waste and conserve natural resources by reusing materials that would otherwise end up in landfills 2. This can help reduce the environmental impact of building construction and promote a healthier indoor environment for building occupants. Recycling can also help reduce energy consumption and greenhouse gas emissions associated with the production of new materials
