2 Table of contents Terms Introduction Purpose of the study Methods Results Summary and recommendations

3 Terms Biogas – gaseous fuel, derived from anaerobic fermentation, consists per cent of methane (CH 4 ), per cent of carbon dioxide (CO 2 ) and other components (N 2, O 2, NH 4, H 2 S). Biomethane – technically purified biogas, comprises more than 97 per cent of methane (CH4)

4 Introduction The current report “Commercial possibilities of Aardlapalu landfill gasses” has been created within the Baltic Sea Region Programme project Baltic Biogas Bus. The report includes different alternative scenarios for the commercial usage possibilities of Aardlapalu landfill gasses.

5 Purposes of the study 1) To obtain information about the possibilities of using Aardlapalu landfill gasses for motor fuel. 2) To determine the production cost of motor-fuel-fit biogas (cost price of 1m 3 and 1 kg of product) 3) To seek alternative commercial usage possibilities of biogas 4) To evaluate the economical feasibility of different commercial usage possibilities of landfill gasses. 5) To study the technological solutions and costs for commercial usage of landfill gas (including transport of biogas to the city of Tartu).

6 1. Biomethane input to (and construction of) the gas pipeline from Aardlapalu landfill to the nearest natural gas grid conjunction point of Eesti Gaas AS (5 km away). 2. The construction and installation of biomethane pipeline from Aardlapalu landfill up to Tartu Veevärk AS (Tähe 118) region, including the building of CNG station and the addition of compressors. 3. The transport of biomethane with CNG cylinders from Aardlapalu landfill to Tartu Veevärk AS (Tähe 118), and the transport of biomethane with CNG cylinders to the nearest exit point of Eesti Gaas AS natural gas grid (5 km). 4. The cost of equipment, needed to purify the landfill gas to consist of per cent of methane (prerequisite of the grid manager) 5. The construction cost of the CNG fuelling station and compressors near the region of Tartu Veevärk AS (Tähe 118). 6. What is the estimated buying-in price for biomethane (appropriate by the natural gas standards) to be channelled into the EG natural gas grid within the next 10 years, and on which input conditions? Price inquiries sent to enterprises

25 Summary and recommendations 1)There is a need for clarification of the landfill gas amount to be produced in Aardlapalu landfill and/or for the harmonisation of the different estimation methods. 2)To obtain the calculated amounts of landfill gas, requires the construction of a modern purification system. 3)All costs are without possible reparations to the private land owners. 4)In the future, it should be considered, whether it would be useful to attach the biogas production system to the Tartu Veevärk sewage mud fermentation system. 5)Commercially, the most feasible venture would be the heat and power production plant scenario, where the electricity would be sold to the network and heat would be lost. The least profitable enterprise is to use biogas as motor fuel. 6)As an alternative, the construction of a gas station near Aardlapalu landfill should be considered. 7)Using biogas as motor fuel should be considered because of social (public health), environmental and of imagological benefits for the city.
