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
