Number 8 Bio's patented bolus uniquely solves grazing emissions while boosting productivity, making the solution appealing for corporates to invest in and producers to adopt on farm. With secured commercial agreements and superior unit economics, they dominate the largest agricultural sector.
Number 8 Bio provides scalable methane mitigation that improves livestock productivity in grazing systems.
Number 8 Bio developed a bolus (slow-release pill) containing a methane inhibitor which converts nutrition normally burped into the atmosphere as methane into animal growth. This provides more profit for farmers by improving growth and yield, and a scalable scope 3 emissions pathway for food companies.
