Traditional cannabis cultivation comes with numerous environmental impacts on air, water, waste, and more, posing increasing concern about the sustainability of this fast-growing industry. But what if you didn’t need the cannabis plant to extract the THC and CBD needed to create cannabis products? In this episode, Dave Rejeski, Director of ELI’s Technology, Innovation, and the Environment Program, talks with Jay Keasling, UC Berkeley professor and synthetic biologist, about his game-changing innovation in cannabis cultivation. Keasling and his teams engineered yeast – yes, the same yeast used to brew beer – to produce high-quality, low-cost THC and CBD at a much lower environmental impact.
