Our mission

Reduce methane emissions from cows

There are around one billion cows on the planet. Together they produce over 4% of the world’s greenhouse gas emissions just by farting and burping methane gas. That’s 2x more emissions than the world’s fleet of airplanes.

Volta Greentech is on a mission to reduce these emissions to mitigate global warming. By providing farmers with an entirely natural seaweed-based feed supplement to drastically reduce the methane emissions produced by dairy cows and beef cattle, Volta Greentech is supporting the agriculture sector in taking a massive leap in going sustainable.

Our solution

A fully natural seaweed-based feed supplement for cows

Our product is an entirely natural seaweed-based feed supplement for cows that, at a daily dose of around 100 grams, can reduce up to 90% of their methane emissions.




The world’s first methane-reduced beef

We just launched LOME, the world's first methane-reduced beef. At the Swedish grocery chain, Coop, there’s now a new product that isn’t available anywhere else in the world: “low methane” beef.

Production designed to scale

Volta Factory 01

There are more than one billion cows on the planet. Looking at existing production methods for seaweed, we quickly realized that we needed to take a different approach to reach the scale we are aiming for. Therefore, Volta Greentech is developing an automated land-based seaweed factory on the Swedish West Coast. With a blueprint specifically designed to be replicated at scale, Volta Factory 01 will supply Volta Greentech’s first commercial partnerships and lay the technical foundation for the coming large scale factories.
