SeaStock Lab-Grown Seaweed Feed Additive Targets Livestock Methane Emissions in Western Australia

Western Australian company SeaStock is using lab-cultivated seaweed to produce a feed additive that reduces methane emissions from livestock. The company grows the seaweed in controlled conditions, avoiding the variability of wild harvest and ensuring a consistent supply for farmers. This approach targets enteric fermentation in cattle and sheep, which is a major source of agricultural methane. The technology could offer a practical tool for the livestock sector to lower its carbon footprint without changing core farming practices. By providing a scalable, lab-based alternative to traditional seaweed sourcing, SeaStock aims to make methane reduction more accessible. The article details the science behind the additive and the company's plans for commercial rollout.
