The report explores the financial requirements to scale up Asparagopsis production to meet the Australian feedlot industry’s demand for methane reduction. Asparagopsis, a red seaweed, reduces methane emissions in cattle by up to 98% when included in feed, making it pivotal for achieving Australia’s Carbon Neutral 2030 target. However, commercial production is still in its infancy, with estimated capital needs ranging from $132 million to $1,062 million depending on adoption and production scale. The report underscores challenges like yield variability, infrastructure costs, and market competition.
