Lome®
Scientific Articles

Developed by Volta Greentech, Lome® is our new algae-inspired feed additive offering market-leading performance. It integrates easily into feeding systems, providing farmers with a safe, cost-effective way to reduce methane emissions and enhance livestock efficiency.

After years of research and development, Lome® is set for a 2026 European market launch, pending regulatory approval.

    • Trials-to-date shows that Lome™ can reduce methane emissions by at least 50%. Scientific publications detailing its efficacy will be released upon market entry, expected in 2026.

    • Lome is safe for animals and humans. Pending EFSA approval will confirm Lome™ 's safety for beef and dairy cattle when used at recommended levels, without any adverse impact on animal health or well-being.

    • Once approved, EFSA will validate that Lome™ has no negative environmental impacts, with its active compounds processed naturally in the cow’s rumen and excreted without harm to the surrounding environment.

    • With regulatory approval, dairy and beef products from animals fed Lome™ will be verified as safe for consumer consumption

    • Lome™ is expected to first gain EU approval for beef cattle 2026, with anticipated approval in the UK shortly after.

Bovaer®
Scientific Articles

Bovaer® is the world’s first feed additive proven to immediately and effectively reduce methane emissions—by an average of 30% in dairy cattle and up to 45% in beef cattle. Developed by dsm-firmenich, Bovaer® offers an impactful, science-backed solution for emissions reduction. Volta Greentech has proudly partnered as its distribution partner in Sweden since 2024, bringing Bovaer’s benefits to farmers committed to sustainability.

    • A meta-analysis by Kebreab et al. (2023), covering 14 global trials, confirmed that the additive Bovaer®, consistently reduces methane production in dairy cattle by 32.7% on average.

    • In a year-long study, Holstein-Friesian dairy cows supplemented with Bovaer® across different lactation stages showed average methane reductions of 21% in production (total methane), 20% in yield (g/kg DMI), and 27% in methane intensity (g/kg FPCM) (Van Gastelen et al., 2024).

    • A report from the Danish Centre for Food and Agriculture demonstrated a 27% methane reduction at a dose of 60 mg Bovaer®/kg per kg dry matter under Danish conditions, aligning with similar findings in Northwestern Europe.

    • The European Food Safety Authority (EFSA) confirms Bovaer® is safe for use in dairy cows, with no observed negative effects on animal health or feed intake at doses up to 100 mg 3-NOP/kg in feed (EFSA 2021).

    • EFSA concluded that Bovaer® does not pose any environmental safety risks. Its active compound, 3-NOP, is metabolized in the cow’s rumen and primarily excreted as CO₂, thus breaking down without harm to ecosystems, even when administered at the highest approved doses (EFSA 2021).

    • According to a life cycle assessment (LCA), the production of Bovaer generates a footprint of 4.84 kg CO₂e per kg of product (DSM, 2024). These emissions, as well as those from transporting the feed additive, are fully included in all emissions reduction accounting and claims.

    • EFSA findings ensure that dairy and meat products from cows fed Bovaer® are safe for consumer use, with no residues of Bovaer® in milk or meat (EFSA 2021).

    • Studies comparing the impact of Bovaer® supplementation on the sensory qualities of milk and dairy products found that Bovaer® does not affect the organoleptic properties of these foods  (Melgar et al., 2020; Lokuge et al., 2024). This outcome aligns with evidence showing that Bovaer® is extensively metabolized in the rumen of cows.

    • Bovaer® is now commercially available in 65+ countries, including the EU/EEA, Australia, Brazil, Canada, Chile, Mexico, Pakistan, Switzerland, Turkey, and the United Kingdom, reflecting broad acceptance across diverse regulatory frameworks.

The scientific name for Bovaer® is 3-nitrooxypropanol (3-NOP)

Red Seaweed
Scientific Articles

Red seaweed represents a natural breakthrough in methane-reducing feed materials, originally discovered and developed by Futurefeed in Australia. Since 2019, Volta Greentech has been a committed partner in red seaweed’s journey.

    • In a 90-day trial, supplementing beef cattle feed with Asparagopsis taxiformis at 0.33% of dry matter resulted in a 98% reduction in methane emissions (Kinley et al., 2020).

    • In a 14-day study with lactating dairy cows, methane emissions were reduced by 20–43% when Asparagopsis armata was included in the feed at 0.92% or 1.84% of dry matter intake (Roque et al., 2019).

    • Over a 147-day period, beef cattle showed methane reductions ranging from 33% to 80% when Asparagopsis taxiformis was included in the diet at 0.45% or 0.83% of feed dry matter across three different dietary regimes (Roque et al., 2021).

    • In a 32-day study, feeding lactating Holstein-Friesian dairy cows Asparagopsis armata oil formulations, methane production was reduced by up to 44% (Alvarez-Hess et al. 2023)

    • Volta Greentech's pilot trials on Swedish farms demonstrated a methane reduction averaging 80% in beef animals, with results verified by the RISE institute and available here.

    • A review of all available studies show no adverse effects on animal health or rumen function when red seaweed is used at the recommended dose, even with methane reductions up to 98% (Eason, 2023).

    • Bromoform, Asparagopsis taxiformis ’s active compound, is categorized as a short-lived substance, breaking down naturally within days and posing minimal risk to atmospheric chemistry. Additionally, Asparagopsis aquaculture represents only a minor fraction of natural seaweed bromoform production, and the compound is metabolized by animals, limiting any potential transfer to the environment (Glasson et al., 2022).

    • Studies confirm no detectable bromoform levels in milk, meat, or other tissues, indicating minimal bioavailability in Asparagopsis-fed animals. These findings support the safety of beef and dairy products from animals treated with Asparagopsis (Glasson et al., 2022).

    • Supplementation of Asparagopsis has no adverse effect on meat quality or taste, with studies showing no differences in tenderness, flavor, or consumer satisfaction between treated and untreated animals (Kinley et al., 2020).

    • Red Seaweed (Asparagopsis) is authorised as a feed material in both the EU and UK. Being a natural product, it does not require EFSA feed additive authorization.
