Bio Bins35 is a new small-scale organics processing system that consist of in-vessel composting bins of 4.5-m3 or 9-m3 capacity that are used to collect putrescible organic waste and turn them into more stable, more useful, disease free by-products. The bin is made of steel and includes a blower, to provide adequate aeration of the waste, preserving aerobic condition for the material’s decomposition, and a biofilter containing organic compost and woody material for controlling leachate waste. The organic waste is stored into the bin for seven days until the waste is stabilised. In most cases when the bins are full they are taken to an organics composter, emptied and returned to the site. Each unit consumes some electricity to run the blower, however, it is a single-phase engine that works on the AC power current. The engine can be plugged into a standard household power socket. BioBins have been used in permanent situations such as at Flinders University and for temporary applications such as at the Moomba Festival in Melbourne and at Womad in Adelaide. Both McDonalds and Coles have conducted trials. Figure 2 shows some examples of Bio Bins.
