Abstract: Vadsbo biogasanläggning ska producera biogas i huvudsak från gödsel, samt uppgradera och distribuera den till slutkund. Konceptet bygger på att biogasproduktionen från gödseln ska optimeras samtidigt som driftskostnaden minskas genom pumpning av gödsel och alternativ uppvärmning med flispanna. Tillsammans utgör de tillämpade teknikerna en förebild för hur en modern biogasanläggning med lantbrukssubstrat kan byggas för att vara resurseffektiv och driftsäker, varför anläggningen har ett stort demonstrationsvärde. Abstract: The biogas plant, referred to as Vadsbo biogas plant, will produce, upgrade, and distribute
biogas to end customers or third parties. Triventus AB has chosen to focus on several areas
that have been assesses to have technical potential for both development and competitiveness
to manage the available resources optimally.
Vadsbo biogas plant is biogas production with focus on agricultural needs. This means that
agricultural residues, mostly liquid manure that are approved by KRAV’s regulations are
used. The concept is based on optimized biogas production from manure while the operating
cost is reduced by pumping of manure and alternative heating with a wood chip furnace. It is
therefore desirable to automatically control and regulate the process in order to get a safe and
efficient operation, while gas production is optimized according to selected organic loading
rate. The biogas is upgraded to vehicle fuel for distribution to end customers or third parties.
The project is expected to contribute to increased production, distribution and use of at least
20.8 GWh of vehicle fuel. The concepts total indirect and direct impact is a reduction in CO2
equivalents and NO3 equivalents by approximately 270 tons and 23 tons respectively.
The total investment for Vadsbo biogas plant is considered to be approximately 63.5 million
SEK. The biggest cost is for buildings, technology, upgrading unit, ground works and a
sanitation unit. The difference between conventional biogas production and Vadsbo biogas
plant is considered to be the extra costs. This extra cost is 13 540 000 SEK.
