Abstract

The paper presents research results obtained in the process of processing biodegradable wastes, resulting from agricultural production as well as municipal waste. Aerobic fermenter EWA (stationed within the Institute for Forage Crops Globoder- Kruševac) was using for this purpose, during the one month testing. Biodegradable material with different ratios of components was used for filling aerobic digester. EWA fermenter is certified device that is used to stabilize and hygienic disposal of biodegradable waste, including sewage sludge and animal products produced in accordance with European Union regulations. Fermenter is intended to be used for combustion in boilers for solid fuels with humidity of biomaterials below 30%.

Highlights

By increasing the number of population in the world, industrialization, urbanization and economic prosperity, the amount of waste, both in developed countries and in developing countries
There is a need of finding a suitable way of processing biodegradable waste
Anaerobic digestion is a process in which biodegradable material decomposes without the presence of oxygen

Summary

Introduction

By increasing the number of population in the world, industrialization, urbanization and economic prosperity, the amount of waste, both in developed countries and in developing countries. The industrially developed country, with a low percentage of the rural population, with a large production of goods and produce large amounts of waste, much higher than developing countries. Biodegradable waste is waste that is suitable for anaerobic or aerobic decomposition, such as products from agricultural and forestry production, food, garden waste, paper and cardboard. According to the morphological composition of municipal waste in the Republic of Serbia, the largest part of the waste is biodegradable waste (31.0%), garden waste (11.9%), cardboard (7.5%) and paper (7.3%) which makes total of 54.7% of the waste that can be decompose (Statistical Office of the Republic of Serbia 2012)
