Biogaasi tootmise ja kasutamise pilootuuring Harjumaal Jäätmed mootorikütuseks

The report investigates the feasibility of producing biomethane from organic waste and energy crops in Harju County, Estonia. It compares two primary scenarios for the Hinnu pig farm: using biogas for combined heat and power (CHP) or upgrading it to biomethane for transport fuel. The analysis concludes that while CHP may offer higher immediate business profitability due to feed-in tariffs, upgrading to biomethane provides greater overall social and environmental benefits, particularly when considering the EU Emissions Trading System.

• The total biomethane production potential for Harju County (excluding Tallinn) by 2020 is estimated at approximately 17.3 million m3/a, with energy crops contributing the largest share at about 75%.
• The Hinnu pig farm pilot project, utilizing pig slurry, slaughterhouse waste, and energy crops, is estimated to produce 1.31 million m3 of biomethane annually.
• Under scenario B1, the Hinnu farm's biogas would be used for combined heat and power, producing up to 4.96 GWh of electricity and 5.27 GWh of heat per year.
• Water scrubbing technology is identified as the optimal purification method for the Hinnu farm due to its productivity level and the availability of treated wastewater from the nearby Kuusalu regional wastewater treatment plant.
• Food waste prevention measures in Harju County (including Tallinn) could reduce emissions by 30,000 to 127,000 tCO2eq and save between 29 and 122 million EUR by 2020, depending on the scenario.
• From a social perspective, producing biomethane for transport fuel is unconditionally more profitable than using it for heat and power, whereas the social profitability of the CHP option depends on the ability to sell both electricity and heat.
• The environmental impact of biogas use depends on the electricity grid structure; replacing Estonian average electricity (87% oil shale) yields higher emission savings per kWh than using it as motor fuel, but the opposite is true when replacing marginal gas-fired electricity.
