Abstract [en]

In BRC EP3 focus has been on new industries. The goal has been to find some new industries where biogas production is a resource‐efficient way to take advantage of material flows that are not used today. From this goal seven activities were formulated and are in short: (A1) Present biogas solutions, (A2) Overview of new industrial sectors in Sweden regarding biogas production, (A3) Possibilities and impossibilities process‐wise, (A4) Energy and environmental impacts, (A5) Societal aspects, (A6) Selection of case studies, and (A7) Case study design. These activities needed different angles of approach and therefore a variety of methods were used in the project, e.g. literature studies, calculations, measurements, interviews and workshops. The results from the activities are presented in short below.

A1: International comparison of biogas production at industrial sites, for example, is impossible to carry out as different classifications are used in different countries. In A1 a way to categorize biogas plants is proposed and discussed.

A2: By screening and geographically pin‐pointing the food industry, eight clusters were chosen for deeper studies. A mapping of biogas potential was thereafter carried out in these clusters. The activity shows great potentials for some of the clusters regarding biogas production.

A3: Process‐related feasibility for opportunities for the clusters studied in A2 is targeted. The general conclusion is that there are no severe aspects that imply that one should not continue working with a specific cluster or a specific substrate found in those clusters, regarding biogas production.

A4: Each cluster found in A2 is assessed in terms of environmental aspects (climate, acidification and eutrophication), energy balance and economy, which were found being the most important assessment criteria when it comes to efficient biogas solutions. The results show, for example, that even though some of the clusters hold a large potential for biogas production some of these clusters do not imply profitable solutions or environmental advantages compared to the present situation of using the substrates. Moreover, the study shows that the end use of the biogas (electricity, heat and vehicle fuel) has significant influence on the results. It is shown that each cluster has a unique combination of substrates and unique alternatives for use of both substrates and produced biogas, implying different beneficial solutions. Sometimes the beneficial solutions differ dependent on what assessment criterion used.

A5: Societal aspects were explored for each cluster found in A2. It is shown that there are differences between the clusters regarding institutional and organizational prerequisites. Important areas have been identified on both a national level (e.g. taxes) and regional level (e.g. cooperation between public and private sectors).

A6: When selecting case studies it is found that the following aspects needs to be considered: (1) biogas potential, (2) character of substrates and other materials, (3) environmental aspects (climate, acidification and eutrophication), (4) influence on energy balances (5) economy, (6) use of biogas, and (7) societal aspects.

A7: When designing case studies the same aspects as for A6 applies. However, when designing the case study it is also vital to consider where to put the system border and also consider the localization of the production unit (e.g. internal at a company or detached).

Moreover, integration of biogas solutions with other types of material or energy flows has to be considered.

All the stated parts in “Motivation and aim” are addressed in the project. Consequently, the target of the project is achieved.
