21. The potential of industrial hemp (Cannabis sativa L.) for biogas production
Sammanfattning : Biofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. LÄS MER
22. The role of biogas in a more sustainable energy system in Sweden
Sammanfattning : There are numerous problems in the world that need to be dealt with in order to achieve sustainable development. The energy system has significant negative impacts on many of these problems, and there is a need for a transition towards more sustainable energy. LÄS MER
23. Intensification of the biogas process by improved process monitoring and biomass retention
Sammanfattning : The utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. LÄS MER
24. How do biogas solutions influence the sustainability of bio-based industrial systems?
Sammanfattning : Biomass is a valuable and limited resource that should be used efficiently. The potential of replacing fossil-based products with bio-based ones produced in biobased industrial systems is huge. One important aim of increasing the share of biobased products is to improve the sustainability of systems for production and consumption. LÄS MER
25. Valorisation of fish waste biomass through recovery of nutritional lipids and biogas
Sammanfattning : Commercial fish catch in Eastern Africa is dominated by Nile Perch. Of the fish that is processed for human consumption, 30-40% is wasted. Currently, these wastes are not fully utilized; they are sold off at low price, converted to low valued products or left to decompose leading to environmental pollution and wastage of bioresource.
