Schmack Biogas wins contract in Bulgaria

A 500 kW biogas plant is being constructed in collaboration with Balkanika Energy PLC

Schwandorf, 1. Novembre 2015. Balkanika Energy PLC and Schmack Biogas GmbH, which is part of the Viessmann Group, are jointly implementing a biogas project in Velkovtski Village, Gabrovo municipality, Bulgaria. The plant, with an electrical output of 500 kilowatts, is being constructed in a mountain region in the central part of Bulgaria. Liquid cow manure, fodder rest, straw, maize silage and whey from a cheese dairy will be used as substrate.

As project developer, Balkanika Energy PLC is also responsible for the general project management and coordination, and plant construction, which will start in November. Schmack Biogas designed the plant and is supplying all the technical components for its operation. Experts from Schmack are also responsible for construction supervision of installation and commissioning.

The project stands out not only due to its production of energy from a difficult substrate (whey), but also because there is great potential for production process optimization. The customer owns a cow farm and a dairy production. The heat and part of the biogas will be used in the production process instead of diesel fuel. Biogas plants for animal farm waste are the only option to avoid the upcoming sanctions to be imposed from 1.01.2016 in connection with EU legislation for methane emissions reduction and responsibility for climate change. On completion, the plant will also be able to meet the annual electricity requirements of approx. 1.150 3-person-households with renewable electricity.
