O2Compost served as a compost sub-consultant for the re-design of an existing biosolids compost facility located at the Port Angeles Landfill. This project included a thorough waste stream analysis for 5, 10, and 30-year term horizons. It also included technical assistance in designing a below-grade aeration system, equipment selection, construction review meetings, and personnel training. The aeration control system for this project was provided by Engineered Compost Systems (ECS) of Seattle, Washington.
