Abstract
The production of fossil fuel hydrocarbon for mechanized farming and agricultural machinery accounts as one of the contributor to fossil energy input in Agricultural sector in Finland. However, renewable natural gas for large diesel engines such as tractors can be produced through biowaste waste treatment i.e waste-to-energy WTE system. This could reduce agricultural production dependence on fossil fuels by contributing to the reduction of GHG emissions. The goal of this project is to carry out a both ALCA and CLCA of biomethane production from biogenic waste feedstock using the EASETECH software. The research compares several upgrading gas-to-liquid technologies, CO2 Capturing and Storage CCS technologies and on-site combined heat and power (CHP) technology, with the view of WTE environmental benefits replacing fossil-based products, direct and indirect land use change, mass flow, energy consumption and the net greenhouse gas emissions in Finland. In this study, seven scenarios will be studied and evaluated. The main gap of the previous scientific study is the lack of comprehensive ALCA and CLCA analyses of environmental sustainability in utilizing biogas for the production of biomethane rather than for electricity and heat. This study is proposing to show that using biogenic waste feedstock in biofuel production substantially can lower the carbon footprint as well as influencing the market demand and supply of sustainable biomethane with a possible subtitutionability of this product by developing a model that represent Finnish energy, agriculture, and transport sectors.
