With the increasing need for energy, energy studies to be obtained from waste gain importance. In this study, it has been tried to determine the amount of biogas energy that can be obtained from olive pomace (pirina), which is produced by processing oil olives. Numerical maps of pirina amounts and potential biogas energy values and location maps of the proposed pirina processing plant were created. The necessary calculations were made by comparing the obtained results with the relevant literature information. In the study, the current potential biogas energy amount was calculated, maps were created and the electricity and gasoline energy equivalent levels of this energy were tried to be calculated using the 2015-2019 data of the Mediterranean, Aegean and Marmara Regions. The total potential amount of pirina in the research area is 1853375.7 tons and the potential biogas energy amount that can be obtained is 33360762.4 MJ. Pirina, which is the production waste after pressing the olives for oil, can be used for energy production. By using pirina to obtain biogas energy, both the utilization of pirina and the development of the regions will be provided.

We conducted the Life Cycle Analysis (LCA) of energy production from biogas for maize and three types of wetland biomass: reed Phragmites australis, sedges Carex elata, and Carex gracilis, and “grassy vegetation” of wet meadows (WM). Biogas energy produced from maize reached over 90 GJ ha−1, which was more than four times higher than that gained from wetland biomass. However, an estimation of energy efficiency (EE) calculated as a ratio of energy input to the energy produced in a biogas plant showed that the wet fermentation (WF) of maize was similar to the values obtained for dry fermentation (DF) of sedge biomass (~0.30 GJ GJ−1). The greenhouse gases (GHG) emissions released during preparation of the feedstock and operation of the biogas plant were 150 g CO2 eq. kWhel.−1 for DF of sedges and 262 g CO2 eq. kWhel.−1 for WF of Phragmites. Compared to the prevailing coal-based power generation in Central Europe, anaerobic digestion (AD) of wetland biomass could contribute to a reduction in GHG emissions by 74% to 85%. However, calculations covering the GHG emissions during the entire process “from field to field” seem to disqualify AD of conservation biomass as valid low-GHG energy supply technology. Estimated emissions ranged between 795 g CO2 eq. kWhel.−1 for DF of Phragmites and 2738 g CO2 eq. kWhel.−1 for the WM and, in most cases, exceeded those related to fossil fuel technologies.

Se evalúa la factibilidad técnica y económica del uso de un ciclo binario del tipo ORC para la generación de electricidad, a partir del aprovechamiento del recurso geotérmico de baja temperatura disponible en varios campos de petróleo en Colombia. Las temperaturas del agua obtenida como subproducto durante la extracción de crudo son 118 ºC en boca de pozo y 82 ºC en etapas de disposición, con caudales de hasta 2,38 m3/s. Para incrementar la eficiencia del ciclo convencional, fueron evaluadas alternativas de calentamiento de la corriente del lado de alta temperatura y de enfriamiento del lado de baja temperatura. Se encontró que un equipo comercial ORC de 280 kW  produciría en uno de los campos 1.165,1 MWh anuales  con un costo de generación de 0,102 U$/KWh. Los resultados de este estudio no permiten la implementación de equipos ORC porque se requieren mayores temperaturas que garanticen la factibilidad técnica.Abstract: These paper analyze the technical and economic feasibility of generating electricity from low temperature geothermal resources available in oil oilfields in Colombia using binary ORC technology. The water obtained as a byproduct during oil extraction has 118°C temperatures at wellhead and 80ºC on average in disposal stages; the water flow rates reach values of 2.38 m3/s. Were studied to improve the efficiency, technical options for additional heating and cooling of hot and cold streams.  According to the results found, 1.165,1 MWh energy production by year and 0,102 U$/KWh in unitary generation cost is for the 280 kW commercial ORC machine. According to the experience developed in this study results do not permit ORC immediate implementation because are necessary higher temperatures to guarantee technical feasibility.Sumário: A viabilidade técnica e econômica da utilização de um ciclo ORC binário para geração de eletricidade a partir da utilização de recursos geotérmicos de baixa temperatura disponíveis em vários campos de petróleo na Colômbia é avaliada. As temperaturas da água obtida como um subproduto durante a extração de petróleo cru são 118 ºC na boca de poço e 82 ºC em fases de distribuição, com vazões de até 2,38 m3/s. Para aumentar a eficiência do ciclo convencional, foram avaliadas (várias) opções de aquecimento da corrente de alta temperatura e de esfriamento do lado de baixa temperatura. Verificou-se que um equipamento comercial ORC de 280 kW poderia gerar em um dos campos 1165,1 MWh anuais a um custo de 0,102 U$/kWh. Estes resultados não permitem a implementação de equipamentos ORC porque precisam-se temperaturas mais altas para assegurar a viabilidade técnica.
