Key resources include ILSR’s Composting and Climate Action Plans Guide, a state… Continue reading POL.240-Policy Tools for Localized Compost Solutions-AC25.USCC
DIV.230-Compost on Every Acre – Aligning Climate Science Policy a…-AC25.USCC
This presentation explores the latest science, policy, and implementation efforts surrounding compost and carbon sequestration, particularly in California and beyond. While regulations like CA’s SB1383 and WA’s HB1799 focus on waste diversion, they lack mechanisms to ensure high-quality compost use. Key discussion points include updates to climate modeling tools (DNDC, DayCent), USDA-backed on-farm compost trials,… Continue reading DIV.230-Compost on Every Acre – Aligning Climate Science Policy a…-AC25.USCC
BUS.245-Operational Turnaround Through Performance Analysis-AC25.USCC
Convertus Group’s acquisition of its first U.S. facility in Manassas, Virginia, marks a major expansion into the U.S. market. The site, previously facing operational inefficiencies, compliance violations, and equipment failures, required a comprehensive transformation strategy. Convertus prioritized process optimization, regulatory compliance, and workforce development without personnel changes. The facility, now processing 90,000 tonnes of organic… Continue reading BUS.245-Operational Turnaround Through Performance Analysis-AC25.USCC
DIV.229-Integrating Compostables into Campus Programs-AC25.USCC
This case study explores Princeton University’s efforts to expand organics recycling from pre-consumer to post-consumer waste, supporting institutional sustainability goals. Through a state DEP grant, university teams collaborated with researchers and industry partners to conduct food waste audits, launch a collection campaign, and test composted materials in an in-vessel composting system. As a result, Princeton… Continue reading DIV.229-Integrating Compostables into Campus Programs-AC25.USCC
PRO.231-Chilling Challenges – ASP Composting in Cold Weather-AC25.USCC
This paper examines the challenges of aerated static pile (ASP) composting at Claystone Waste in Canada’s cold climate, where temperatures fluctuate by over 70°C annually. It explores the effects of cold weather on microbial activity, equipment performance, and moisture management, as well as the need for tailored feedstock strategies. Through field studies and operational analysis,… Continue reading PRO.231-Chilling Challenges – ASP Composting in Cold Weather-AC25.USCC
PRO.230-Navigating Neighbor Site Complaints in Brazil-AC25.USCC
A composting facility in Pereiras, São Paulo, successfully implemented a technology framework to improve odor control and efficiency. By using real-time monitoring of compost parameters and weather data, the facility reduced odor issues, prevented anaerobic conditions, and enhanced compost quality. This case study highlights the importance of technology in optimizing composting operations and serves as… Continue reading PRO.230-Navigating Neighbor Site Complaints in Brazil-AC25.USCC
USE.236-Soil Growth & Water Impacts from Compost And Biochar-AC25.CREF
This study explores the use of biochar to regulate compost amendments and mitigate nutrient runoff, reducing the risk of eutrophication. Large-scale experiments simulated roadside embankments with different compost-biochar soil mixtures. Results showed that compost enhanced plant growth but increased nitrogen and phosphorus runoff, while biochar reduced nutrient export and improved moisture retention. Combining compost and… Continue reading USE.236-Soil Growth & Water Impacts from Compost And Biochar-AC25.CREF
