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. (Chemical Engineering <strong>and</strong> Technology
