Valmet has announced that it will rebuild the pretreatment system for RE Energy’s biorefinery in Kalundborg, Denmark.

The order was included in Valmet’s orders received in 2Q21 and the delivery is planned for the first half of 2022. The value of the order will not be disclosed.

“RE Energy acquired the old biorefinery with the clear intention to bring it back in operation. This includes replacing the pretreatment system to achieve stable operation. We have great expectations that we, through the corporation and with the Valmet team and their technology, will achieve this goal,” says Henrik Maimann, CEO RE Energy.

RE Energy’s biorefinery, which is based on straw, will produce 2G bioethanol and lignin, and in collaboration with a partner, utilise the hemicellulose to produce new innovative ingredients.

Valmet will replace the old feeding system of the plant with a new biomass feeding system based on Valmet’s patented Force feed technology and a new steam explosion unit. The plant will be able to handle 5 tph of absolutely dry wheat straw (6 tph with 20% moisture in the straw).
