Household waste CO2 footprint API

Compute landfill CO2e (largely methane) from municipal waste streams using EPA-derived factors (kg CO2e/kg): food 2.53, paper 1.04, textile 1.1, yard 0.58, mixed 0.7, plastic 0.04, glass/metal 0.02. Annualized from a weekly or yearly period. Returns a per-stream breakdown, total and annual kg/tonnes CO2e and tree equivalents. Answers 'CO2 of my weekly trash','landfill emissions from food waste','annual waste footprint','methane from household garbage'.
