How One Startup Turns Coffee Grounds Into Biofuel for Bus...

What this episode covers

Lucas and Luna explore the unlikely journey of coffee waste to bus fuel. A startup in London has figured out how to collect used coffee grounds from cafes and turn them into a biodiesel blend that powers city buses. They break down the numbers: each tonne of grounds yields about 200 liters of oil, and the company is already processing over 5,000 tonnes a year. Lucas questions whether the math scales beyond a niche, and Luna pushes back with data on global coffee waste volumes. It's a concrete look at one of the more surprising corners of the biofuel world — and a reminder that feedstock innovation matters as much as engine technology. #CoffeeGrounds #Biofuel #WasteToFuel #Biodiesel #London #CircularEconomy #Decarbonization #SustainableTransport #Feedstock #Startup #Business #Technology #ClimateTech #EnergyTransition #FexingoBusiness #BusinessPodcast #ClimateTechPodcast #LucasAndLuna Keep every episode free: buymeacoffee.com/fexingo
