FAC.216-Minimizing Energy Inputs for Compost Manufacturing-AC22.USCC

The cost of energy inputs in the form or diesel and electricity are significant factors in the overall cost of operating a composting facility.   Finding strategies that minimize those inputs will reduce operating expenses as well as emissions of CO2 equivalents.  The primary areas of energy use once the feedstocks are delivered to the facility are: * Preprocessing and grinding * Material handling to place on the compost pad * Method of aeration (either forced aeration, windrow turning or static pile) * Energy use for odor control and leachate management * Curing and screening The presenter will provide typical energy use for each of these steps using manufacturers specifications and operational data.  The presenter will review three operational scenarios for estimated energy consumption: * Windrow vs ASP for energy inputs for forced aeration vs turning * Processing in a building with biofiltration vs outside with biocover and leachate collection and treatment * Using a course grind which uses less fuel and provides a more porous mix which in turn requires less energy to aerate but yields less product   The intent of the presentation is to bring more awareness to the equipment selection and facility design to minimize energy use and CO2e emissions.  The target audience are facility operators and system designers and regulators concerned with GHG and air pollution emissions from composting operations.
