DB Breweries' plant at Washdyke in Timaru is not only churning out beer - it's also making its own compost.
Three years ago the company started a project that would see it treat its own wastewater, instead of using the city's treatment system.
The byproduct is used as compost and diverted from landfill. Brewery manager Adrian Finlayson talks about how the project came about, what it involves and his own interesting career brewing beer in unusual places.
