Readiness Level

Priorities for scaling

high-risk pilotingcatalysing development

This slow-release capsule, designed for placement in the animal’s rumen, administers a steady dose of tribromomethane—a synthetic compound inspired by the methane-inhibiting properties of seaweed. By targeting key enzymes in the methanogenesis process in the rumen, the bolus effectively blocks methane production for up to six months. Its biodegradable nature eliminates retrieval requirements, and is predicted to be economically viable delivering a enteric methane reduction of at least 70%.

This innovation is particularly suited for pasture-based systems where feed-based methane inhibitors are impractical.

Food System Area

agricultural inputs & primary production practiceswaste

Enteric methane emissions from livestock are a significant source of agricultural greenhouse gases, contributing to climate change. Existing methane reduction strategies, such as feed additives, are not feasible for grazing systems where controlled feeding is difficult. The biodegradable bolus addresses this gap by offering a long-term, practical solution that reduces methane emissions directly at the source while requiring minimal intervention.

Problem area

What impact could it have?

Human health impact

medium

The human health impacts are low to medium. Indirect benefits arise from mitigating climate change, which reduces climate-related health risks.

Environmental impact

high

The environmental impact is significant. Reducing methane emissions directly addresses global warming potential, and the bolus’s biodegradable nature minimizes environmental harm. However, further research is needed to assess the environmental footprint of tribromomethane production and degradation.

Livelihood impact

medium

The livelihood impacts are moderate and positive. Farmers benefit through reduced emissions, compliance with regulatory targets, and potential revenue from carbon credits. Smallholders may face adoption barriers without adequate support.

Socio-cultural impact

medium

The socio-cultural impacts are likely medium. Initial skepticism may arise due to unfamiliarity with the technology, but its ease of use and demonstrated efficacy are expected to drive acceptance among farmers over time.

Equity impact

medium

The equity impacts are medium. While the bolus provides benefits across farming systems, access for resource-poor farmers may require targeted interventions to ensure widespread adoption.

Potential for transformative impact

medium

The bolus’s ability to reduce methane emissions by up to 70% over six months positions it as a transformative solution for mitigating livestock methane emissions globally, offering an essential piece of the puzzle of innovations addressing these emissions. However, it remains important to consider that livestock have plenty of other negative impacts on the environment – making this innovation important for methane emissions but an incremental improvement in the big picture of sustainable livestock systems.

What factors influence scaling?

This innovation is bundled with digital farm management tools, including an electronic tracking device that allows farmers to track which livestock have already been treated.

The application is global, with high relevance for countries with extensive pasture-based livestock.

Within this, large-scale farms are expected to adopt this technology initially, with subsidies and technical support enabling uptake among smallholders in the long term.

Low. Due to the slow-release, this innovation offers a minimally disruptive innovation, not needing daily dosage or even application during feeding.

Potential risks include incomplete degradation of the bolus in certain environmental conditions, safety concerns related to tribromomethane dosing, and potential impacts on rumen microbiota. Ongoing research and monitoring are critical to address these issues.
