A pulp mill in Sweden is ending its use of non-renewable LPG in favor of a biomass boiler. This news release from Waggeryd Cell says it will invest about $7 million to run the flash dryer on biomass, expected to be up and running next March and reducing the mill’s fossil carbon dioxide emissions by 85 percent.
Waggeryd Cell produces bleached CTMP and ever since start-up in 1989 the whole production has been flash dried using LPG as heat source. When the new boiler has started in September 2016, LPG will be totally replaced by bioenergy. It is a grate boiler with an effect of about 12 MW. The supplier is Urbas, an Austrian company specialising in systems designed to extract energy from wet and coarse wood fuels from sawmills, woodworking factories and general forestry thinning. It is a turnkey project and Urbas is responsible for the whole delivery, including projecting, mounting and start-up.
“This is yet another of the environmental investments we have done since we began modernising the mill fifteen years ago,” says Ulf Karlsson, MD Waggeryd Cell. “By replacing LPG for our flash dryer with heat from the new biomass boiler we will reduce our emissions of fossil carbon dioxide by 85 % at the same time as we reduce our costs. The boiler will be fuelled by sawdust, oversized wood chips and fibre residuals from our process as well as bark and fuel wood mainly supplied from our owner ATA Group’s sawmills.”
Urbas has been designing, building and pioneering energy systems for use of biomass fuels for more than 20 years.
