Abstract

The development of the global economy and booming population growth have resulted in the increased consumption of energy and the growing need for alternative energy sources. This paper presents the use of yield methods for assessing the economic justification of investments in biogas plants, as well as a review of the economic results of biomass energy production, with the aim of determining the present value of future benefits from the electrical and heat energy generated in such plants for fruit drying and processing purposes. The purpose of this paper is to determine the economic viability of investments in renewable energy sources such as biogas plants that can be used effectively in the production and storage of dried fruit. The yield-method results obtained indicate that the production of electrical and heat energy from waste biomass in biogas plants can produce positive financial results.

Highlights

The growing population in the world and the global increase of economic activities lead to an increasing need for the production and consumption of energy
The revenues from biomass heat energy production, which can be used for fruit drying and processing, were included in the calculation of the total revenues
The planned revenues from the delivered electrical energy accounted for 82 % of the total revenues, whereas the planned revenues from the heat energy produced accounted for 18 % of the total revenues

Summary

Introduction

The growing population in the world and the global increase of economic activities lead to an increasing need for the production and consumption of energy. Fossil fuels such as oil, coal and natural gas (made from fossils of plants and animals) are non-renewable sources of energy which are continuously depleting. Environmental pollution issues have been receiving increased attention as they pose significant challenges to the global economic growth. Natural resources and the environment itself are becoming the limiting factors for human economic activities. Serbia has a relatively high growth rate of energy consumption (6-7 % annually) and primary energy reserves six times lower than the world average. The use and management of energy sources in Serbia must be very rational, exploiting all available sources such as waste fuel (Zekić et al, 2010)
