In this initiative, I successfully harnessed the potential of spent brewery grain from a local brewery by cultivating Cordyceps Militaris, a valuable medicinal mushroom. The process involved transforming waste into a high-value added product, reducing environmental impact and contributing to the health and well-being of our community. Key Features: Sustainable Transformation: My project focused on the sustainable utilization of organic brewery waste, promoting a circular economy and minimizing environmental footprint. Micro-Medicinal Mushroom Farming: I cultivated Cordyceps Militaris, known for its medicinal properties, creating a local source for this sought-after product. London-Centric Innovation: Situated in the heart of London, my initiative aligned with the city's ambition of innovation and sustainability, making a positive impact on both local businesses and the community https://wiki.greenlab.org/2018/05/31/cordyceps/
