About four-and-a-half years ago Ben Bushell launched Community Compost, a social enterprise in Nelson aiming to tackle the problem of food waste going into landfill.
Before long they were getting too much food waste to handle, so Ben set about inventing a machine that would automate large-scale composting.
His journey is the subject of the new 45-minute documentary 'Ben & bEartha', produced independently by Happen Films.
The star of the film and founder of Community Compost Nelson Ben Bushell talks to Jesse.
