Utilization of Apple Pruning Residues as a Source of Biomass Energy: A Case Study in Isparta Province

Abstract

The prefeasibility study of a biomass fuelled CHP based on a steam Rankine cycle employing back-pressure process proposed to utilize apple pruning residues as biomass sources to obtain bioenergy in Isparta Province was carried out. Since Eǧirdir has the highest apple production among the districts of Isparta province, it is reasonable to build biomass fuelled CHP plant in Eǧirdir district. Therefore, economical analysis was conducted for the catchment area with the radius of 59 km taking Eǧirdir district as the central point. Both equations and data used to calculate the capital and operating cost of biomass CHP plants were obtained from the available literature. The production of electrical and heat energy, and revenues were evaluated. The economic viability of 7.8 MW e CHP plant was evaluated based on the net present value (NPV), benefit-to-cost ratio (B/C ratio), internal rate of return (IRR), and payback period (PBP) considering electricity purchase prices of 0.066 euro cent/kWh and heat sale price of 0.0225 euro cent/kWh. It has been concluded that certain financial mechanisms have to be put into effect, such as increasing market price of electricity produced from CHP plants to give an incentive to producers, as well as fundraising to support construction of CHP plants, and offering both long-term credits and tax breaks for investors.

Elementary, Chemical and Energy Characterization of “Dendê” (Elaeis guineensis Jacq.) Waste in the State of Pará

“…It was observed that the mean moisture content of palm oil residues is low (7.97%) compared to other results found for apple pruning (37.66%) and coffee beans and bark residues (15.66%) (Vale et al, 2007;Ekinci, 2011). According to Luk et al (2013), when it comes to samples for the generation of energy, high value for this parameter is not interesting, thus confirming an advantage of palm oil residues for energy use, being also considered an essential factor in the coal vegetable production.…”

Determination of Energy Use Efficiency and Greenhouse Gas Emission (GHG) of Cotton Cultivation in Batman Province: A Case Study from Beşiri District

“…Efficiency usage of energy source is important to decrease operating cost and decrease emissions of air contaminants and greenhouse gases (Demirbas and Urkmez 2006;Mujeebu et al 2009a;2009b;Ekinci 2011). Taking the recommendations proposed by this study into consideration can contribute to better energy use efficiency in the future.…”

De-Oiled Rice Bran as a Source of Bioethanol

“…It is used for medicines, cosmetics, and industrial materials and production is increasing every year (Sanchez and Cardona, 2008). With increasing oil prices and global environmental concerns, bioethanol production has recently become a focus of attention (Bai et al, 2008;Mussatto et al, 2010;Ekinci, 2011). Ethanol is the main liquid energy carrier produced biologically from two types of biomass-starch/ sucrose containing energy crops such as sugarcane and corn (1st generation bioethanol technology) and lignocellulosic residues/wastes (2nd generation bioethanol technology) (Karakashev et al, 2007).…”
