I live in a second floor apartment with a small balcony. In my kitchen I have a small vented container where I place kitchen scraps as I'm preparing food -- like this:
About once a week when this gets full, I transfer everything into a 20 L sealed plastic pail on my balcony, like this:
Once that is full (about every six to eight weeks), I take it in my car (while doing other errands, of course) to a nearby community garden where a coworker has a plot and dump it in the communal compost bin.
My question is, does storing compost made of kitchen scraps in a sealed container for up to eight weeks cause any problems for the open-air compost bin where I eventually place it?
A few points on my compost:
- Scraps are about 80% raw fruit and vegetable peelings, with some egg shells, produce that has gone bad, and a few odds and ends from houseplants.
- The bucket is sealed airtight to keep out the rain.
- It is on a balcony facing east, so receives full morning sunlight.
- Climate is humid continental -- highs of 35 °C in the summer, lows of -20 °C in the winter.
- I have no need for the humus myself -- I compost to reduce the volume of waste going to the landfill, and keep the smells out of my house.
Note: There are some great answers to the question "Is it feasible to compost in an apartment in a city like New York?", but nothing on my specific question.
