Carbon-free farm launches on Ishigaki Island with focus on circularity

Yaeyama Islands Carbon-Free Farm LLC has unveiled their “Carbon-Free Farm Concept” with the launch of a new ranch operation on Ishigaki Island. It integrates environmental stewardship with agricultural practices, aiming to minimize environmental impact through the efficient use and reuse of resources, with a focus on harmonizing with the natural environment, while also tailoring to local needs. It sets a model for carbon-neutral and circular economy business models in rural areas.

One of the cornerstone initiatives of the farm is the integrated production of black wagyu, specifically the renowned “Ishigaki Beef.” By taking over existing livestock farming operations on the island, the farm plans to utilize existing production resources while implementing renovations to facilities such as cow sheds. The farm is planning for a new brand of black wagyu known as “Decarbonized Beef.” This brand will be developed through a specialized feeding method that suppresses methane emissions (a major contributor to global warming.) The goal is to create a methane-free wagyu that stands alongside Ishigaki Beef as a premium product.

Beyond cattle farming, manure produced by the cattle, along with additional manure collected from other livestock farmers on the island, will be provided to a group-operated methane fermentation biogas power generation business. This manure, totaling over 100 tons per day, will be used as a raw material for electricity generation. The digestate produced during the power generation process will be returned to local farmers as a specialized fertilizer. Not only does this create a circular system, it also addresses the severe environmental pollution caused by livestock manure in Ishigaki City. Furthermore, the farm plans to upcycle old, non-functional cow sheds into hydroponic farms. These farms will utilize electricity generated by the biogas power plant and the biomass-derived liquid fertilizer.

Looking forward, the Yaeyama Islands Carbon-Free Farm has plans to develop accommodation facilities, as well as farm-operated barbecue restaurants and cafes, making the farm a destination for both residents and tourists. By leveraging local resources and working in collaboration with the community, the farm aims to create new attractions and industries that contribute to the region’s circularity.
