Australia
Bioenergy and bioeconomy topics gain importance in Australia and New Zealand but also in some countries of Oceania. The potential of residues such as woody biomass, wheat straw, sugar cane (processing) residues, municipal biowaste, slurry and manure is huge. However, the single most important fuel (in Australia) is bagasse for co-generation. In some countries, biomethane and biodiesel out of (micro-)algae is starting to play a role. In general, the sector is still relatively small which is often mainly due to logistics and large distances.
Country experiences
DBFZ has realized a couple of research interchanges in both directions with Australia. The main topics were the utilization of vinasse and filter cake for biogas production and the re-use of agricultural residues for energy production and nutrient recovery by anaerobic digestion. DBFZ participated also in a study on anaerobic digestion systems for rural primary industry enterprises.
