3.2. Changes in TOC
Organic matter is the basic requisite for microbial survival and
reproduction during composting, and the changes in the organic
matter, to some extent, reflect the composting process. The TOC
profiles of the different reactors during the composting process
are shown in Fig. 3. The TOC of the ordinary, greenhouse, and solar
reactors decreased by 20.1%, 20.5%, and 31.3%, respectively
