FAC.222-Addressing Odors Using Intelligent Emissions Monitoring-AC22.USCC

Odor concerns continue to challenge the composting industry, with complaints from neighbouring communities being frequent while solutions are few. This study presents a novel solution to address odors from composting facilities using continuous, intelligent emissions monitoring of problematic compounds. The system uses one high-end instrument to measure concentrations of hydrogen sulfide (H_2S) in air samples… Continue reading FAC.222-Addressing Odors Using Intelligent Emissions Monitoring-AC22.USCC

FAC.221-Challenging Odor Issues at a Large Industrial Composter-AC22.USCC

This presentation is going to take a closer look at one of the biggest, but most underestimated, risks to industrial composters: odor. We will take a deep dive into the various components of composting sites and how/why they can contribute to odor issues. We will discuss the science of odor as well as the complexity… Continue reading FAC.221-Challenging Odor Issues at a Large Industrial Composter-AC22.USCC

FAC.220-Compost Aeration and Heat Recovery at Country Oaks Landscape Supply-AC22.USCC

Country Oaks Landscape Supply in Burton, MI has been increasing its scale of compost production.  In February 2020 a Compost Aeration and Heat Recovery (CAHR) system was installed by Agrilab Technologies Inc. (AGT).  Over 30,000 cubic yards (CY) of mixed feedstocks are composted annually on an 8-zone working pad.  This has enabled Country Oaks to… Continue reading FAC.220-Compost Aeration and Heat Recovery at Country Oaks Landscape Supply-AC22.USCC

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
