Abstract

Otpad je jedan od najvećih problema zaštite okoliša u današnje vrijeme. Rastom ljudskog stanovništva planeta Zemlje, proporcinalno raste i količina nastalog otpada. Biološkom obradom smanjuje se količina biorazgradivog otpada koji se zbrinjava odlaganjem. Kompostiranjem se biootpad pomoću mikroorganizama prevodi u stabilan produkt kompost, prilikom čega nastaju CO2, NH3, H2O i toplina. Iz biorazgradivog otpada, u odlagalištu i tijekom procesa kompostiranja, nastaje procjedna voda kao rezultat biokemijskih procesa i okolišnih uvjeta koja zahtijeva obradu prije ispuštanja u okoliš. U ovom radu istraživan je utjecaj sastava supstrata na proces biorazgradnje. Biorazgradnja procjedne vode iz biootpada i proces kompostiranja provedeni su u šaržnim uvjetima pri čemu su provedene fizikalno-kemijska i mikrobiološka analiza procjedne vode i biootpada. Učinkovitost procesa biorazgradnje procjedne vode i kompostiranja biootpada iznosila je 91 i 46 %.

Abstract (english)

Waste is one of the biggest environmental problems in today's time. With the growth of the human population of the planet Earth, the quantity of waste generated proportionally increases. The amount of biodegradable waste which is disposed can be reduced with biological treatment. By composting, biowaste is converted by microorganisms into the stable product compost, CO2, NH3, H2O and heat. From biodegradable waste, in landfill and during the composting process, the leachate is generated as the result of biochemical processes and environmental conditions. Prior to its discharge into the environment, the generated leachate requires treatment. In this work the influence of substrate composition on the biodegradation process was investigated. The biodegradation of biowaste leachate and composting process were conducted in batch conditions where physico-chemical and microbiological analyses of the leachate and biowaste were carried out. The efficiency of the biodegradation process of leachate and biowaste composting were 91 and 46 %.
