Abstract

The aim of this study was to investigate the recycling of organic matter in the food waste by degrading aerobically and evaluation of the CO2 emissions. With this aim, food waste with the content of 5-7-10 % TS was degraded aerobically. The pH in all the reactors was observed within the range of 6.5-7. The highest CO2 production rate was obtained from 5 % TS. Removal was achieved at the rates of 5 % TS and 57 % in COD and TOC. CO2 production rate was calculated as 38.53 g CO2/h/kg TOCw. Moreover, CO2 production potential of the food waste was identified. A batch, single-stage reactor was used to determine the food waste pre-treatment. Finally, food waste in landfill areas was recycled and evaluated by without taking.
