Executive Summary
Zoos and aquariums generate substantial amounts of organic waste, including animal excreta, plant trimmings, food scraps such as cafeteria waste and uneaten animal feed, and animal bedding materials. Composting these materials not only reduces landfill waste but also produces nutrient-rich soil amendments that can support local agriculture and horticulture. This white paper explores the importance of composting organic waste at zoos and aquariums, with a focus on reaching optimal temperatures for decomposing primate and carnivore waste.
