520 |a The carbon conversion efficiency of composting with food, yard, and cotton waste is analyzed herein. We demonstrate the ability of air-aerated and oxygen-aerated composting reactors to achieve carbon conversion efficiencies between 23 and 60 % and cotton mass degradation between 37 and 99 %. This carbon conversion efficiency is equivalent to removing 0.32 - 0.97 tonnes of CO2 per tonne of dry biomass waste processed, which compares favorably to the carbon removal potential of anaerobic digestion (0.04 - 0.40 t-CO2/t-biomass) and hydrothermal liquefaction (0.49 - 0.62 t-CO2/t-biomass), two BiCRS technologies renowned for their ability to process wet feedstocks. 12 million tonnes of textile waste are landfilled annually, and through composting 10.8 million tonnes of that waste (over 8 % of annual municipal solid waste in the U.S.) could be converted into gaseous CO2 for capture and soil amendment. Samples containing cotton in the initial feedstock had on average a 1.2 % higher carbon conversion efficiency than those without cotton. Air-aerated reactors consistently generated CO2 concentrations above 18 % while oxygen-aerated reactors generated CO2 concentrations above 80 %, which can reduce the minimum work of CO2 capture by 70 and 93 % relative to atmospheric CO2 capture, respectively. Microbial diversity decreased throughout the composting process, but samples with cotton and without cotton had virtually the same number of amplicon sequence variants after a thirty-day composting trial
