155 agricultural side of the project. They have contributed with economical security <strong>and</strong> legitimacy. (Chemical Engineering <strong>and</strong> Technology department KTH., 2007) Picture 42.: The Växtkraft biogas plant in Västerås (Chemical Engineering <strong>and</strong> Technology department KTH,. 2007) Bio-waste In Västerås there are three alternatives of h<strong>and</strong>ling the bio waste: 1. You can participate in the source separation scheme, which means that you put the bio waste in particular paper bags, see (Picture 43.) below. The bags are kept in the kitchen <strong>and</strong> placed in a ventilated plastic bin when it is filled. They are collected separately <strong>and</strong> treated at the biogas plant. 2. Another alternative is to have home composting in the backyard. 3. The last alternative is to not separate the waste at all. The bio waste is treated with residual kitchen waste, which means that it is incinerated. (Chemical Engineering <strong>and</strong> Technology department KTH., 2007)
156 Picture 43.: Paper bag with household waste at the input station at the biogas plant in Västerås (Chemical Engineering <strong>and</strong> Technology department KTH,. 2007) There are lower fees for those who are source separating <strong>and</strong> the quantity of participants in the source separation scheme is very high – approximately 90 % of the households participate in the scheme. The bins are placed outdoors in residential districts <strong>and</strong> indoors, in separate refuse chambers or recycling houses, in apartment buildings. The bio waste is collected biweekly in residential districts <strong>and</strong> once a week in apartment building areas. The bio waste from institutional kitchens is h<strong>and</strong>led in the same way. Slurry exhauster vehicles collect the grease trap removal sludge from restaurants <strong>and</strong> institutional kitchens <strong>and</strong> deliver it directly to the biogas plant. The Waste Management Administration of Västerås is responsible for the collection of the waste from households <strong>and</strong> restaurants <strong>and</strong> the transport to the treatment plant. Vafab, which is a regional company founded by the municipality of Västerås together with surrounding municipalities, has the responsibility to treat the municipal waste. The waste must be quality controlled, <strong>and</strong> Vafab is responsible for the quality control as well. At the quality control foreign materials are separated <strong>and</strong> tests are made to ensure the quality dem<strong>and</strong>s are fulfilled.
