Abstract
Kompostiranje je tehnološki proces gospodarenja otpadom kojim se pomoću mikroorganizama u aerobnim uvjetima obrađuje i stabilizira biološki razgradivi otpad te prevodi u kompost. Stoga je prepoznat kao ekološki prihvatljiv način zbrinjavanja biootpada. U ovom radu praćen je proces kompostiranja biootpada u rotacijskom komposteru valjkastog oblika (zatvoreni sustav) i otvorenoj posudi (otvoreni sustav). Biootpad je prikupljen u studentskoj menzi Kampus u okviru Studentskog centra Sveučilišta u Splitu. Tijekom kompostiranja u oba sustava su praćeni parametri: temperatura, sadržaj suhe i hlapive tvari, sadržaj vlage, ugljika, dušika, pH, električna vodljivost te C/N omjer. Uspoređene su vrijednosti mjerenih parametara u otvorenom i zatvorenom sustavu. Rezultati promjene sadržaja organske tvari su obrađeni prema kinetičkom modelu prvog reda. Dobivena su dobra slaganja eksperimentalnih rezultata s modelom, a brzina razgradnje organske tvari je veća pri kompostiranju u otvorenoj posudi, u odnosu na rotacijski komposter.
Abstract (english)
Composting is a technological process of waste management which use microorganisms under aerobic conditions to treat and stabilize biodegradable waste and translate it to compost. Therefore, it is recognized as an environmentally friendly way of biowaste management. In this paper, the process of biowaste composting in a cylindrical rotary composter (closed system) and an open container (open system) was monitored. Biowaste was collected in the Campus student canteen within the Student Center of the University of Split. During composting in both systems, the following parameters were monitored: temperature, dry and volatile matter content, moisture content, carbon and nitrogen content, pH, electrical conductivity and C/N ratio. The values of measured parameters in the open and closed system were compared. The experimental results of organic matter content during composting process were tested according to the first order kinetic model. Good agreement of the experimental results with the model was obtained. The rate of organic matter decomposition was higher when composting in an open vessel, compared to a rotary composter.
