VIS.211-Drawdown Georgia, A Case Study On Composting As A Mechanism to Address Global Warming-AC22.USCC

Project Drawdown has done a pragmatic assessment of transformational changes that will be necessary to curtail global warming. When we analyze these projects, we find many of them can be clustered into a broader narrative of Organic Circularity. Researchers in Georgia have adopted the Project Drawdown methodology and created a hierarchy of initiatives to achieve… Continue reading VIS.211-Drawdown Georgia, A Case Study On Composting As A Mechanism to Address Global Warming-AC22.USCC

VIS.210-A Circular Economy to Scale Carbon Farming and Compost Infrastructure-AC22.USCC

Zero Foodprint is a 501.c3 leading public private collaborations with governments in CA, CO to scale carbon farming. We generate funds from businesses and citizens and depoly grants in conjunction with trusted conservation networks like the Conservation Districts and Cooperative Extensions. We are scaling this circular economy with a long term vision of enabling direct… Continue reading VIS.210-A Circular Economy to Scale Carbon Farming and Compost Infrastructure-AC22.USCC

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.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.311-The Application of Laboratory Aeration Demand Testing to Facility Design-AC22.CREF

The efficiency with which aerobic bacteria consume oxygen and convert organic matter (OM) to CO2 is the primary measure of composting stabilization rates and a determining factor in air emissions.  Process conditions (primarily temperature and oxygen) and feedstock characteristics determine the efficiency of this process.  Researchers, such as McCartney, Sundberg, and others, have used highly… Continue reading FAC.311-The Application of Laboratory Aeration Demand Testing to Facility Design-AC22.CREF
