On our farm, whatever is ripe and ready for the picking we pick and people take. The vegetables are then put into blue box recycling boxes and loaded onto my two ton truck for transport to the depots. In the city we have people who act as community coordinators to help distribute the food. These are volunteers who love the idea. Typically, I'll just back up into someone's driveway and unload 30 boxes into a garage.
People know when the pickup times.
I'll generally hang around for about 20 minutes at each stop if people want to talk to their farmer that day. Also, some people who don't do their own composting, bring compostable materials which I bring back to the farm. It is a no energy using recycling system because I'm there anyway delivering vegetables. It is a closed system. The only problem with it is that it is a bit time consuming to wash out the last bits of material from the blue boxes.
