Recycling CO2 impact calculator API

Compute CO2e avoided by recycling vs landfill per material using EPA WARM factors (kg CO2e avoided/kg): aluminum 9.13, steel 1.79, glass 0.31, paper 0.46, cardboard 0.36, plastic 1.02, PET 1.13. Returns a per-material breakdown, total kg/tonnes CO2e avoided and tree equivalents. Answers 'CO2 saved by recycling aluminum','impact of recycling 5kg of cans','emissions avoided vs landfill','which material saves most by recycling'.
