Composting can support green building in several ways. First, composting can reduce the amount of construction and demolition waste that ends up in landfills. By diverting organic materials such as wood, paper, cardboard, and food scraps from the waste stream, composting can save space, money, and resources. Second, composting can provide a valuable resource for landscaping and gardening. Compost can improve the soil quality, water retention, and plant growth of green roofs, walls, and gardens. Compost can also help prevent soil erosion and runoff, which can protect the water quality and biodiversity of the surrounding environment. Third, composting can create a positive social impact. Composting can educate and engage the building occupants and the community about the benefits of organic waste management. Composting can also foster a sense of responsibility, stewardship, and connection with nature.
