Anna de la Vega is director of The Urban Worm, a company providing repurposed wheelie bins as wormeries in Nottingham. She is dedicated to building a sustainable soil and reducing waste by using worms to create 'Black Gold'. Last summer she spent several weeks travelling in the US and Cuba to learn from vermiculturalists there, through the Winston Churchill Fellowship. We are very pleased to have Anna to come to tell us what she discovered on a fascinating trip.
