We collected the compost and froze it in the freezer.
I figured, it’s only three months. It can sit in there. We mostly used plastic ice cream containers. By the end of the three-month period, room for ice cream didn’t exist.
Once we got to the house and set up the make-shift compost, it ate this stuff up. Though our first collection which we didn’t freeze, did not make it and produced many happy fruit flies.
Lesson learned.
Freeze it.
Attempting zero waste lifestyle in a military household 
well done..what a clever idea
Freezing before putting into the compost pile does he added bonus of beginning the breakdown process. Fruit flies will always come, invited or no. You can put a dish of apple cider vinegar with a drop of dish soap in it. When attracted to the shallow dish, they will sink upon lighting. He soap reduces the surface tension. Great fly trap!
