– Vafab Miljö aB, Västerås
Vafab Miljö works with sustainable and environmentally
sound handling of waste, and is owned by the regional municipalities.
The population of the region is about 300,000,
and there are more than 10,000 businesses that generate
waste.
Växtkraft is a biogas plant in which bio-waste from households
and restaurants is digested, together with ley crops
from farms and sludge from grease separators in largescale
kitchens. The biogas that is produced in the process
can be utilised as environmentally compatible fuel for motor
vehicles.
Biofertiliser is also obtained as a residual product, something
that farmers can spread back onto the fields as an
ecological nutrient. The Växtkraft project creates a rotation
of energy and plant nutrients.

Agroetanol’s plant in Norrköping uses energy from the nearby biomass CHP
for its processes.
The ley crops are stored as silage in plastic for later use in the biogas plant.
Green house using biomass for heating
– tåkern Grönt, Väderstad
Tåkern Grönt is a company that cultivates vegetables in
greenhouses. The total greenhouse area is about 10,400
m2 . There are two boilers, one for straw and one new boiler
for wood chips. The greenhouses, the family house, and
other buildings are connected to the two boilers that feed
an accumulator of 200 m3 .
The biomass amount needed for this heating has replaced
about 360 m3 mineral oil. Tåkern Grönt is the first company
that KRAV* has approved for ecological cultivation in this
field.
*KRAV is a key player in the organic market in Sweden. KRAV develops
organic standards and promotes the KRAV-label.

Ethanol plant using grain as feed stock
– Lantmännen, agroetanol, norrköping
Sweden’s first large ethanol plant, run by Agroetanol, owners
are Lantmännen, a large farmer’s crop marketing association,
and LRF, the Federation of Swedish Farmers.
The ethanol plant is in full operation on Händelö since 2001.
Händelö is an island less than 10 km from the centre of
Norrköping. The site is close to the oil depot and a biomass
fired power plant. The steam and electrical power needed
to operate the plant originate from renewable sources. The
steam, which is primarily used for distillation and drying of
feed, is produced in the bio-fuelled power plant close by.
A new, three times as large a plant, was opened in 2008 at
the same location. The new plant needs 400,000 tonnes
of grain, from 70,000 hectares of land, and will produce
150,000 m3 of ethanol. Biogas is also produced from distillers
waste.
