Malmberg to supply upgrading unit to Solrød Biogas in Denmark

Sweden-headed wastewater treatment and biogas technology providers MalmbergGruppen AB has announced that its subsidiary Malmberg Water AB (Malmberg) has been selected by Denmark-headed biogas plant developer and operator Bigadan A/S to supply a biogas upgrading unit to Solrød Biogas A/S outside Copenhagen.

Malmberg has been selected by Bigadan to supply a biogas upgrading plant to the Solrød Biogas plant outside Copenhagen. Commissioned in 2016, the Solrød Biogas plant is a first-of-its-kind biogas plant in Denmark that attracts widespread international interest such as these delegates from the 2019 BioPowerON conference (photo courtesy Andrew Lang).

Commissioned in 2016, Solrød Biogas was built in close cooperation with CP Kelco, VEKS, Chr. Hansen, Roskilde University, Bigadan, and the agricultural sector. A range of food industry and agricultural residues including manure are used.

However, Solrød is a first-of-its-kind plant in Denmark for its use of seaweed, collected from the Bay of Køge and Solrød Beach – up to 7 000 tonnes per annum is removed from the beaches to improve the quality of the bathing water while providing green energy.

Malmberg will supply a Malmberg Compact water scrubber type upgrading plant with a capacity to turn up to 2 800 Nm3/h biogas into biomethane (aka green gas or enewable natural gas – RNG). The RNG will be injected into the natural gas grid and the plant will be in operation in October 2019.

Malmberg has up to date delivered more than 110 biogas upgrading plants in Europe and China. The new order for Solrød Biogas will be the fourteenth upgrading plant for Malmberg in Denmark including to Bigadan facilities in Horsens and Limfjorden.
