44% of bread baked around the world is never eaten – but for Toast Ale, this is an opportunity. Matt and Lukxmi meet Rob Wilson, "Chief Toaster" at Toast Ale, to hear how the brewery is creating delicious beer from crusts that would have otherwise ended up in the bin. They are also joined by Linda Grieder, founder of RethinkResource, to discuss how the food industry can do more to divert waste and side streams, by putting them to good use (and making money along the way).
