This master thesis depicts process of composting of food waste using an electric composter. Electric composters are eligible solution for waste management of catering facilities, that are in accordance with current legislation. The problematics of the food waste is being described using the literature review. The main goal of this thesis is quality evaluation of the final product of the composting process. The main focus is on evaluation of enzymatic activity of compost named arylsulfatase, which corelate with sulphur cycle. The enzymatic activity itself is being measured by spectrophotometer UV/VIS Lambda 25 (Perkin-Elmer, Shelton, CT, USA) using 5 mMp -Nitrophenyl sulfate as a substrate. Thesis also studies pH values of compost and phototoxicity (by Phytotoxkit test), that demonstrate an effect of final product of composting on white mustard seeds (Sinapis alba L.).
