FAC.219-Successful Operation of a Large-Scale Composting Facility with Restrictive Air Permits-AC22.USCC

The Napa aerated static pile facility began operations in early 2020 with a hard-won air permit to accept 315 tons/day of food and yard waste, and other residuals.  The primary goal of the 10,700-word air permit was to keep the VOC emission factor below 1.8 lbs/ton of feedstock out of concerns for public health.  Starting… Continue reading FAC.219-Successful Operation of a Large-Scale Composting Facility with Restrictive Air Permits-AC22.USCC

FAC.218-Hybrid Approach to Composting-AC22.USCC

The presentation covers a design and operational approach for compost facilities that accept food and yard waste.  Technologies to be covered include aerated static pile (ASP) systems; equipment to mix feedstocks; compost turners; dump trucks and conveyors for material handling; and, star and trommel screens.  An ASP system can be combined with open windrow technology… Continue reading FAC.218-Hybrid Approach to Composting-AC22.USCC

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