The project has studied aspects of introducing a biodegradable bag made of partly fossil biodegradable oils, starch and with dolomite content for collection of food waste. The report is aimed at organizations conducting collection, pretreatment and treatment of food waste, owners of anaerobic digestion facilities and producers of equipment for collection of food waste. The goal was to see if it is possible to develop a biobag with dolomite content that are user friendly, without risk for degradation at the customer, degradable in an anaerobic digester, in conformity with SPCR 120, workable within current pretreatment and with an overall environmental performance on the full life cycle comparable to alternative products such as paper or plastic bags. The project contains three main parts. Part 1 Five different levels of dolomite content have been developed where some hade starch from potatoes and some from maize. User trials have been performed in households and restaurants during the autumn of 2012 and spring of 2013. The households preferred the bio bag over the paper bag. The restaurants preferred the bag with 15 percent dolomite and considered the bags with 25 percent dolomite to have a lower strength. Pretreatment at NSR was performed with 45L bags with 25 percent dolomite. The new biobag got stuck in the machines. Analysis showed that the limits for SPCR120 was mostly achieved. Part 2 Part two investigated the degradability of the biobag with batch anaerobic digestion tests. The testing consisted of graft and substrate to mimic the conditions in an anaerobic reactor. The biodegradable bags were evaluated by comparing the weight loss after digestion at thermophile temperature. The analysed bags were treated as normally done with food waste in the collection areas. Tests showed no contribution to the methane from the biobags, i.e. there was practically no degradation. Biobag 0, 1, 2 and 3 showed no difference in weight. Biobag 3p and the paperbag showed a significant weight loss compared to the abiotic control. Part 3 The environmental assessment of the biobag with dolomite content was performed as a life cycle assessment and an expert judgement of land use related issues. The results show that the biobag with dolomite content has a comparable environmental impact to the paper bag and lower than the plastic bag. Effects on the food waste collection system are much more important than production of the bags from an environmental perspective. The land use shows that production of ingredients for the biobag should be produced in traceable supply chains to ensure that there is no competition with food production. For the scale of swedish food waste collection bags, the production of ingredients is fairly unproblematic.
