FAC.120-Targeted Strategies to Remove Contaminants from the Compos…-AC26.USCC
This session presents San Diego’s pilot program at The Greenery to address increased contamination in residential organics following the city’s mandatory green bin rollout. Strategies include front-end handpicking, route-level analysis, targeted outreach, lid-flip inspections, and a citywide marketing campaign. Attendees will learn how operational changes, data-driven evaluation, and community engagement can reduce contamination, control costs,… Continue reading FAC.120-Targeted Strategies to Remove Contaminants from the Compos…-AC26.USCC
PRO.239-A scalable model for odor free biosolids composting at a r…-AC26.USCC
This session highlights Jacobs Solutions’ successful odor mitigation at the Southbridge, MA WWTP biosolids composting facility. By optimizing pile structure, increasing quality-controlled wood amendments, monitoring free air space, temperature, and oxygen, Jacobs eliminated odor complaints. The case demonstrates a scalable approach combining physical matrix management, aeration control, and monitoring to control odors in biosolids composting… Continue reading PRO.239-A scalable model for odor free biosolids composting at a r…-AC26.USCC
PRO.238-Contamination Control from the Ground Up – Practical Strat…-AC26.USCC
This session highlights how Green Mountain Compost, Vermont’s largest food scrap facility, reduced contamination following the 2020 Universal Recycling Law. Strategies include clear material acceptance messaging, a formal contamination policy with load checks and reporting, in-house hauling, and equipment upgrades. Attendees will learn practical lessons from incremental implementation, resulting in cleaner compost, better hauler communication,… Continue reading PRO.238-Contamination Control from the Ground Up – Practical Strat…-AC26.USCC

USE.325-Compost Without Compromise: Maintaining Crop-Available Nit…-AC26.CREF
This study examined co-application of compost and urine-recovered ammonium sulfate in short-season vegetable systems. Compost alone caused nitrogen immobilization, but combining it with medium or high fertilizer rates provided net plant-available nitrogen while doubling soil carbon storage in high compost treatments. Results suggest that pairing compost with recycled fertilizer can enhance nitrogen availability and sequester… Continue reading USE.325-Compost Without Compromise: Maintaining Crop-Available Nit…-AC26.CREF
DIV.242-Scaling Composting Access Through Smart Tech and Strategic…-AC26.USCC
This session highlights Washington, D.C.’s successful expansion of food waste drop-off through smart, app-secured bins and community partnerships. From early farmers market programs to a citywide rollout, the initiative diverted over 80 tons of food waste in four months. Attendees will learn lessons in strategic site selection, program design, and community engagement, offering a replicable… Continue reading DIV.242-Scaling Composting Access Through Smart Tech and Strategic…-AC26.USCC

USE.242-Compost Biochar and Combined Applications Improve Soil Mo…-AC26.CREF
This study in Maine wild blueberry fields found that compost and compost-plus-biochar applications improved soil nutrient levels (boron, calcium, magnesium, potassium) and increased soil moisture by up to 12 percentage points during dry periods. Foliar nutrient levels also increased, though no yield changes were observed in 2024. The results suggest that compost and biochar enhance… Continue reading USE.242-Compost Biochar and Combined Applications Improve Soil Mo…-AC26.CREF
SCI.213-The Gold Beneath – Compost Amendments for Carbon Storage a…-AC26.CREF
This three-year study in California’s Central Valley found that combining annual compost applications with cover crops in nut orchards significantly improved soil health and carbon sequestration. Results included increased labile carbon, doubled microbial biomass, improved nitrogen retention, stronger soil structure, and nearly doubled total soil organic carbon in the upper 30 cm. The findings demonstrate that… Continue reading SCI.213-The Gold Beneath – Compost Amendments for Carbon Storage a…-AC26.CREF
