I’m not sure how big your compost bin is, but this product works great.

I am living in Seattle, where meat and dairy scraps (and nearly all food) are allowed in our compost bin. It has begun smelling soooooo bad that I had to bleach the bin. I am now worried about the bleach and what to do to keep the smell down from now on. I used to use compost bags, however, that is an added expense. I will just go back to bags if I have to, but I am wondering if there is a way to keep the smell down. It seems to be that the guys that pick it up don’t empty it all the way. Not their fault I think. Any product that is cheaper than bags that can keep down any odor?

Thanks a million!!
