Thanks to Citizens Committee for New York for our Composting Grant. Here’s our calculations for the past year:

Our 3 bin pallet compost bin holds 4 square feet of compostables, 50% is food waste and 50% is garden waste and leaves. We turned these bins 5-6 times since April 2015. Our collection bin holds approximately  4 feet square or 64 cubic feet of materials – which has cooked down to much less, especially as the weather has warmed.  Therefore conservatively estimating 64 cubic feet of compostables, multiplied by  5 compost turns, our three bin compost system has therefore diverted 320 cubic feet or about 12 cubic yards of compostables.

According to this calculator  1 cubic yard of compost is 800 pounds.  12 cubic yards of compostables might weigh around half the weight of finished compost. We therefore diverted approximately 4,800 pounds of organics from the waste stream in our open compost collection bin. The volume of finished compost cooked down in our removal bin usually ends up being about half of that, so we produced 6 cubic yards of compost which also weighed approximately 4,800 pounds. This compost went to amending the soil of garden plots and tree pits around the community. We will soon have a compost give-away to empty out this bin in preparation for building our new bins.

We collected approximately 100 cubic feet or 3.7 cubic yards of fall leaves in our browns holding bin. Using this calculator for dry leaves, we estimate that we diverted 1271 pounds of leaves from the waste stream. These leaves will eventually be mixed with greens throughout the year.
