Volta Greentech
SwedenTransitioned — no longer Asparagopsis-basedVolta Greentech is a Swedish company that previously cultivated Asparagopsis taxiformis and conducted research into its use as a livestock feed additive for methane reduction. The company built a pilot cultivation facility in Lysekil, Sweden, staffed by a dedicated team of 14 biologists and engineers, who prototyped indoor and greenhouse cultivation of Asparagopsis in tanks and large ponds. In Swedish farm trials, adding 1% of the seaweed to a cow's diet reduced methane emissions by about 80%. However, the company was unable to reach the productivity rates required to make the financials viable, as the capital required for equipment per kilogram produced was too high relative to potential revenue. Volta Greentech subsequently developed a second-generation synthetic feed additive, Lome®, which uses chemically synthesised bromoform as its active ingredient rather than Asparagopsis biomass. The company describes Lome® as more than 10x cheaper and less resource-intensive than growing seaweed. As of August 17, 2026 — the date of the company's published technical blog post — Volta Greentech was in the final stages of preparing an EFSA (European Food Safety Authority) application for Lome® for beef cattle in Europe. No EU market placement approval had been granted at that date. Volta Greentech's current commercial activities are focused on Lome®, not Asparagopsis.
Current product: Lome® — synthetic bromoform-based feed additive (composition: maltodextrin, rapeseed oil, starch, emulsifying agent, bromoform 3%). Not Asparagopsis-based. As of August 17, 2026, EFSA application in preparation for EU market placement approval for beef cattle; not yet approved in the EU.
