Cows produce over 4% of the global greenhouse gas emissions by releasing methane gas, which is more than twice as much emission as all the world’s airplanes. Backed by more than six years of research from international universities and research bodies, Volta Greentech is now commercialising their seaweed based feed supplement for cow feed which could reduce up to 80% of their methane emissions.

To meet the increasing global demand for the solution, Volta Greentech is rethinking how to produce seaweed.

AFRY have been selected to support the construction of Volta Factory 01 as the preferred engineering partner to Volta Greentech and now supports the construction of the facility along with the company’s in-house team of biologists and marine scientists.

“AFRYs exceptional competence in engineering combined with their extensive experience of production systems for aquaculture makes them the perfect partner”, says Fredrik Åkerman, CEO at Volta Greentech.

Located in the city of Lysekil on the Swedish west coast, Volta Factory 01 is a modular…

Swedens largest feed company Lantmännen, is collaborating with the Swedish startup Volta Greentech’s to examine how a red seaweed feed supplement that have a methane reducing effects on ruminants can be added to the feed of cows. At Lantmännen’s trial farm and beef center Viken, experiments has been done to examine how adding the red seaweed to cattle feed can significantly reduce the climate impact of Swedish cattle.

Several new international studies have show that a small supplementation of the red seaweed Asparagopsis taxiformis in the feed of cows results in a significant reduction in methane production. Some of these…
