Non profit doesn't mean there will be no profit it means profit isn't the aim of the business. The overheads are paid and new stock acquired and the workers are paid a decent wage and any excess is also put back into the operation or into the aims of the organisation(funding and expenses for the workshops on recycling for example). It sounds like the initial investment will be paid off the same as any business loan to a startup and then any excesses will be rolled back in to their aims. I'm sure there are better definitions of non profit out there but I have found sometimes that people have trouble with the idea. The capitalist view of profit being the be all and end all seems to rule.
This way the community gains an asset that aims to be beneficial for the community without the profit motive.
