Biogaasi tootmise ja kasutamise pilootuuring Lääne-Virumaal Jäätmed mootorikütuseks

The report investigates the feasibility of producing biomethane from waste in Lääne-Viru County, Estonia. It identifies a total biomethane production potential of up to 24.4 million m3/a by 2020, with energy crops as the largest resource. The study proposes a pilot plant in Rakvere using wet digestion technology and amine scrubbing for purification. While combined heat and power (CHP) is more profitable for a private operator due to feed-in tariffs, the report concludes that using biomethane as motor fuel provides higher social and environmental benefits for society as a whole.

• The total biomethane production potential in Lääne-Viru County for 2020 is estimated at up to 24.4 million m3/a. Energy crops represent the largest share at approximately 66%, followed by industrial bio-waste (ca 13%), sewage sludge (11.5%), liquid manure (9%), and bio-waste in municipal waste (0.6%).
• The report proposes a pilot biogas plant in the outskirts of Rakvere, specifically near the wastewater treatment plant, to be close to the county's largest waste producers: AS Rakvere Lihakombinaat, Estonian Spirit Ltd, and AS Rakvere Vesi. The recommended technology is wet digestion with a vertical digester of approximately 3,000 m3 and a pasteurizer to handle potential pathogens from industrial substrates.
• For the purification of biogas into biomethane (over 99% CH4), the report selects the amine scrubbing method due to its high efficiency and very low methane losses (less than 0.1%).
• Comparing two usage scenarios for the Rakvere plant: Scenario B1 (combined heat and power - CHP) and Scenario B2 (motor fuel). While B1 is more profitable for the operator due to feed-in tariffs and lower investment costs, B2 (biomethane for transport) is found to be more socially profitable and provides a greater overall improvement in environmental conditions.
• The analysis of food waste prevention in Lääne-Viru County suggests that by 2020, depending on the success of prevention measures, greenhouse gas emissions could be reduced by 5,000 to 17,000 tCO2eq and costs could be saved by 5 to 17 million EUR.
