Özet
This paper presents a regional techno-economic and environmental screening of electricity production from biomass in Yalova, Türkiye, based on a secondary biomass inventory, logistics and conversion assumptions, an auditable MATLAB/Octave feedstock allocation model, a consistent tariff-feedstock-CAPEX-O&M test, and emissions screening. The source inventory indicates 610,498 tons/year of biomass that translates into 55,040 ton-of-equivalent-oil/year of biomass. The optimization is not presented as a new mathematical algorithm; its contribution is to convert the regional inventory into an operational procurement decision under explicit availability, delivered-cost, yield, and throughput constraints. Annual throughput at 220,000 t leads to the minimum cost scenario of 140,573 t/year of chicken litter with 79,427 t/year of forest residues to generate 40.37 GWh/year (net equivalent of 5.42 MW @ 85% capacity factor) at a delivered feedstock cost of 286.8 USD/MWh. Using the same tariff as 2788.4 TRY/MWh and an exchange rate of 35 TRY/USD consistently to the optimized scenario, the resulting tariff is 79.67 USD/MWh, while electricity income is estimated at USD 3.22 million/year, whereas total feedstock expenditure is approximately USD 11.58 million/year before fixed O&M costs. The result of consistency of 25 years for electricity-only economics therefore cannot show any economic viability in electricity production based on the above assumptions. Environmental impacts are presented as screening results but not the carbon benefit through the life cycle: The grid factor of the grid for ‘other renewable’ projects in Turkey for 2023 (0.5350 tCO2/MWh) shows a grid displacement of about 21.6 ktCO2/year, and direct biogenic CO2 and non-CO2/air pollutant emissions need to be reported separately based on feedstock sourcing and combustion controls and alternative waste disposal. The results support adaptive feedstock planning, but they do not constitute a final investment or life-cycle assessment.
