Composting Poultry Offal. The objective of this project was to develop a successful composting process of poultry offal to produce finished compost that is environmentally sound, economically feasible, and returns nutrients to the farm. Compost was made with materials produced on Lopez Island and was compared to compost made from traditional composting materials that were imported to the island. Efficacy of composting as well as costs were compared.
