Keep a nut jar on the counter for fresh scraps. When full, transfer to leftover plastic bags (bread, grocery, used gallon zip locs) and store that in the freezer until the transfer station is open. Being frozen makes it easy to dump in the town compost bins (and keeps the fruit flies away in the house). I usually go to the transfer station 1-2x a month and gather my frozen bags in a five gallon bucket for easy transportation.
