Environmental sustainability of aerobic treatment of biowaste
Sažetak
Waste is one of the biggest environmental problems in today's time. With the growth of the human population on the planet Earth, the quantity of waste generated proportionally increases. Under the domain of waste management, great importance is placed on the reduction of waste disposal in landfills. A considerable amount of municipal solid waste is biowaste which can cause greenhouse gas and leachate emissions leading to environmental problems. The production of biowaste across the supply chain is inevitable and it is desirable to reclaim value from this waste stream. Through composting process organic biodegradable fractions from biowaste are biochemically decomposed to stable end products. Generated leachate can be treated by aerobic biodegradation process. Biological treatment is cost effective and environmentally acceptable approach for biowaste and leachate management. In this work the influence of substrate composition on the biodegradation process was investigated. The biodegradation of organic matter in the leachate from biowaste and the composting process were conducted in batch conditions where physico- chemical and microbiological analyses of the leachate and biowaste were carried out. The efficiency of biodegradation of organic matter from leachate and composting of biowaste was 91 % and 46 %, respectively.
