Ulsan, South Korea
In November 2007, Scandinavian Biogas was awarded a contract with the city of Ulsan, South Korea to improve the biogas production and increase the treatment of food waste at the Youngyun wastewater treatment plant. Scandinavian Biogas will significantly improve the digestion in the existing biogas reactors by re-designing the biogas process. The treatment of food waste will increase from 40 metric ton per day to 180 ton per day. This is both profitable for the city as well as highly beneficial for the environment.
Scandinavian Biogas is investing in a pre-treatment facility for the food waste, re-designing and re-building the biogas process, adding ultrasound treatment and gas cleaning equipment. We will sell the green gas to a local buyer. Our contract is for 15 years and the production will start in the second half of 2009.

Varberg, Sweden
In January, 2008, Scandinavian Biogas was a awarded a contract with the municipality of Varberg in western Sweden to increase the biogas production at the local wastewater plant from 0.4M Nm3 of gas per year to 3.5M Nm3 of gas per year. Scandinavian Biogas will upgrade the gas to natural gas quality and inject it into the local gas grid.
Scandinavian Biogas will re-design the biogas process, install ultrasound treatment and cryogenic gas cleaning equipment. We will take a long-term responsibility for the process under a 15-year profit-sharing contract with the plant owner. The production will start in 2009.

Overview of the wastewater treatment plant in Varberg
Loudden, Stockholm, Sweden
In December 2008, Scandinavian Biogas entered a unique co-operation with Stockholm Water to produce biogas from agricultural by-products and leftover food. Loudden is a former waste water treatment plant which operation was halted five years ago. The existing facilities will partly be utilized for the new purpose together with complementing equipment. Scandinavian Biogas is now redesigning and rebuilding the plant so that it can produce biogas for transport use.
The biogas is to be produced from damaged crops and leftover produce from the cleaning of mills at the first stage and later also from restaurant waste and other leftover food. The biogas plant is expected to have a 1 100 m3 digester and an annual production of about 750 000 Nm3 biogas for transport use (equivalent to about 800 000 litres of petrol). The yearly benefit in terms of reduced greenhouse gas emissions is close to two million kilos of fossil carbon dioxide. The inauguration of the facility is expected to take place in the spring of 2010.
