Abstract:
The environmental aspects of biogas production based on pre-treated slurry have been investigated in a life cycle perspective. The pre-treatment consists of concentrating the slurry using a separation technology. Significant environmental benefits, compared to the status quo slurry management, can be obtained for slurry, especially regarding reductions of the contributions to global warming, but the results depend to a large extent on the efficiency of the separation technology. Adding separation after the biogas plant can contribute to a more efficient management of the phosphorus.

Abstract in Danish:
Miljømæssige aspekter af biogasproduktion baseret på separeret gylle er undersøgt ved en livscyklusvurdering (LCA). Der kan opnås betydelige miljømæssige fordele sammenlignet med "normal" håndtering af gylle, særligt med hensyn til at reducere bidrag til global opvarmning. Resultaterne afhænger i høj grad af effektiviteten af separationsteknologien før biogasanlægget. Separation efter biogasanlægget kan tilføjes, hvilket kan bidrage til en mere effektiv udnyttelse af fosfor.
