In this episode of Sustain Now, we dive into an innovative solution to combat one of the most pressing environmental issues: methane emissions from livestock. The guest, Steve Meller, CEO and Co-founder of CH4 Global, takes us on a journey of discovering how seaweed can significantly reduce methane emissions from cattle.

Founded in 2018, CH4 Global is on a mission to tackle methane—a greenhouse gas with more than 80 times the warming potential of CO2 over 20 years. Methane is primarily emitted by livestock, especially cattle, through their digestive process known as enteric fermentation. CH4 Global has developed a groundbreaking feed supplement using red seaweed (Asparagopsis) that, when added in small amounts to cattle feed, can reduce methane emissions by up to 90%. This solution is backed by scientific research from the Commonwealth Scientific and Industrial Research Organization (CSIRO) and others, showing its incredible potential to curb the climate impact of livestock farming.

The episode also delves into CH4 Global's journey, from the launch of their first product, Methane Tamer™ Beef Feedlot, in April 2023, to the company's ambitious goal of reducing greenhouse gas emissions at gigatonne scale by 2030. Steve shares insights into the challenges and opportunities the company faces, as they work to scale up seaweed production to meet global demand. With a $47 million investment backing their efforts, CH4 Global is making strides in producing and processing Asparagopsis efficiently, aiming to help farmers reduce emissions and tackle climate change head-on.

The episode covers pivotal moments in Steve's entrepreneurial journey, including insights on entrepreneurship later in life, the challenges of scaling a business, and the loneliness of running a startup. Steve reflects on his experiences and how mentorship from seasoned entrepreneurs can play a critical role in guiding younger startups.

We also explore the global methane challenge and the importance of focusing on this potent greenhouse gas, especially with initiatives like the 2021 Global Methane Pledge. Despite increased international efforts, more innovation is needed in agriculture to address methane emissions. CH4 Global’s solution is one of the many important tools required to mitigate the effects of climate change.

Join us as we discuss the science, challenges, and future of CH4 Global’s seaweed-based solution to methane emissions in livestock, and how such innovations offer hope for solving the climate crisis. Tune in for an inspiring conversation on nature-based solutions and entrepreneurship that could reshape the future of sustainable agriculture.
