Biogaasi tootmise ja kasutamise pilootuuring Harjumaal Jäätmed mootorikütuseks

This report, produced as part of the "From Waste to Traffic Fuel" (W-Fuel) project, analyzes the potential for biogas production and its use as motor fuel in Harju County, Estonia. It evaluates biomass resources, proposes a pilot biogas plant at the Hinnu pig farm, and compares the environmental and economic impacts of using biogas for combined heat and power (CHP) versus upgrading it to biomethane for transport fuel.

• The total biomethane production potential for Harju County (excluding Tallinn) by 2020 is estimated at approximately 17.3 million m3/a. Energy crops represent the largest share of this potential at about 75%, followed by agricultural manure (ca 12%), sewage sludge (5.6%), and municipal and industrial bio-waste (4.4% and 3% respectively).
• The report proposes a pilot biogas plant at the Hinnu pig farm in Allika village, Kuusalu parish. Using a mix of pig slurry, slaughterhouse waste, sewage sludge, and energy crops, the plant could produce approximately 1.31 million m3 of biomethane annually.
• Two primary utilization scenarios for the Hinnu plant were analyzed: Variant B1, using biogas for combined heat and power (CHP) to produce up to 5 GWh of electricity and 5.2 GWh of heat; and Variant B2, upgrading biogas to biomethane for use as motor fuel.
• For the Hinnu plant, water scrubbing technology is recommended for biogas upgrading because it is the most common technology and the plant can utilize treated wastewater from the nearby Kuusalu regional wastewater treatment plant as process water.
• The energy output from the Hinnu plant under the biomethane scenario (approx. 12 million kWh/year) could support roughly 1,200 cars or 135 heavy-duty trucks.
• Environmental impact analysis indicates that using biogas as motor fuel (Variant B2) provides a greater overall improvement in environmental status than using it for electricity, particularly when considering the EU Emissions Trading System (EU ETS).
• For an individual operator, a CHP plant may be more financially attractive due to lower investment costs and existing feed-in tariffs for renewable electricity, provided a market for the heat exists.
• The report estimates that avoiding food waste in Harju County (including Tallinn) by 2020 could reduce emissions by 30,000 to 127,000 tCO2eq and save between 29 and 122 million EUR, depending on the success of the avoidance measures.
