Alonso, Marcos, 2010. Investeringsalternativ för gårdsbaserad bioanläggning vid SLU. First cycle, G2E. Uppsala: SLU, Dept. of Economics



A Biogas plant in SLU’s (Swedish University of Agricultural Sciences) management sustains to behave in con-nection with the new animal stables at Lövsta. There will primarily manure from stables that rot to biogas. The biogas plant will also have the capacity that rot others substrates that can arise in the farm operation. The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.

This study has implemented multiple cases study of different investment scenarios. The central aim is to assess investment economic consequences in investing in farm based in the co-generation (also combined heat and power, CHP) biogas production. A current issue is how profitability and environmentally good stem a biogas plant will be evaluated in relation to an investment. The value is paid from an assessment of the goods for the environment counted in monetary value with regard for the reduction of climate gases. In order to reply on the question if profitability must everyone substrate that is feed in the biogas reactor be identified, is quantified and be evaluated.

The study is based on those resources and conditions that today are for this project. This means that the analysis takes into consideration substrates that are available today around SLU’ s stables (Kungsängsgården Uppsala) in the form of rot from stable and feed spills. Here comes also to be formed yet another alternative with the central thought to analyze others possible vegetables substrates, such as banks, corns, cereals, feed root fruits (carrots, potato, etc.) and cereal crusher.

The calculation model is based on Net present value (NPV) where all payment powers from respective module be discounted. The study takes also considerations to the environment consequences based on the Cost Benefit Analysis (CBA). The basis investment's costs are set to 12,3 and 18,3 millions SEK (Swedish crown) and in-vestment alternative with regard for the different interest rates (r) 4 % and 6 % for each alternative. All invest-ment alternatives that use cogeneration are in next table.
