Trash - a side effect of going vegan

In our pre-vegan family days we used the garbage service once a week. It comes twice, but only during heavy yard work days did we ever need it. Now we use it every 3 times, but sometimes that's just to keep the smell down, not because the can is full. It puzzles both my husband and me as to why we our trash has gone down so significantly. Even adding in yard work days doesn't increase that need very much.

Now I wish I paid per pick-up, I could get rewarded for being a little greener.
