Location: Argentina
Funder(s): Climate and Clean Air Coalition (CCAC), Global Methane Hub (GMH)
Co-funded by the Climate and Clean Air Coalition (CCAC) and the Global Methane Hub (GMH), Delterra worked with the Buenos Aires city government to redesign one organic waste collection route serving large food businesses, paired with a behavior change campaign and digital tracking tools.
Results included a 45% increase in organics recovered, a 25% reduction in cost per ton, and improved sorting quality from 68% to nearly 100% in just 12 weeks. Buenos Aires plans to scale to 10 routes by 2027, with potential to recover 6,000+ tons of organics per year and prevent an estimated 1.7 million tons of CO2e emissions by 2050.
