The liquids expressed are also full of biology. Add sugar, they tend to the bacterial, add proteins and they tend to the fungal. They are used as bio-weapons, and bringers of soil water and digested nutrients amongst other talents.
I do not do much of that myself, but a barrel composter with holes on the end or even an upright barrel would serve for collecting liquids in a bucket. Some just use a sheet of plastic under a loose pile with preforated pipes introduced for air.
I have a small vertical container composter and my wife has faithfully put stuff from the kitchen in it for years. I never mentioned that I never put a bottom in it, and as a result it never fills up. If I did not have it that way, she would no doubt have me hauling the chopped bits out, and I have enough to do as it is. I feel so anyway. So this bottom part is a big deal. Barrels that lay horizontally upon wheels work well, they generally have no holes but the lids are suspect and I imagine would leak should the thing be turned wrong. But compost is heavy, and I would favor either a relatively small barrel to kick about or if the volume requires it, then a large barrel on the wheels for turning. Anyone having pitchforked a pile of compost for aeration would appreciate a better way.
Here are a couple of bigger tumblers. The little ones seem to cost as much or several times more and are as much as 3x smaller. The slick looking picture is a tumbler sold via Lowes Home Improvement Stores.
