We do the same: "We neutalize formalin then dump it down the drain with CAW (copious amounts of water) Alcohol is flushed with CAW." But we recycle our xylene. For every two gal. recycled we usually get 1 3/4 back. Of course you still need some new xylene on hand for the coverslipper. The formalin neutralizer is much cheaper than hauling it away. And the xylene recycler is small, fits in a corner, has a fume sensor on it so we aren't exposed too much :) Over time (several years) the recycler will show it's cost savings verses buying gallons of new xylene and hauling it all away. This really showed itself to be true this last sumer when our old recycler broke down in May and we didn't get the new one in until September!!
