I just got back into composting a few years back and since I compost nearly everything I can get my hands on, I concluded my compost bin was too small, so I beefed it up a bit, now I can easily get a season out of this without overflowing.
I don't monitor, stir, water or proportion the materials, everything is just dumped in as I come across it.
Everything goes in here, cardboard, paper, kitchen waste, coffee grounds, expired breads, cereals, flours and the like, yard waste, trub, bad beer, yeast, hair clippings, vacuum cleaner collection, rabbit manure and bedding, chinchilla manure and bedding, urea, ash, Bio-Char, pond waste, spent soil from pots, etc...
From time to time, meat, bones, cheese and the like makes its way to the compost bin.
Some cardboard that does not get recycled goes into the fire pit for fire starting, this includes cardboards that have a glossy surface or a glossy type paint on the box.
I don't compost my tomato plants, weeds or sunflowers, these go into the firepit with bones and dog poo that is in the yard at the time.
This is either left to burn to ash or choked out prior to becoming ash make bio-char. Weeds I sometimes but very rarely put in a 5 gallon bucket and let it sit out, the weeds dry up, the bucket fills up with rain water then I'll dump this in the compost bin.
Most of the time the rabbit and chinchilla waste goes directly in the raised beds with some bio-char and urea.
My composter usually works pretty slow but when I added a few gallons of trub, the thing literally talk off, I could feel the heat come off of it when I stood next to it and the level dropped 12 inches in a few days, I couldn't believe it.
I think it must have been active yeast in the trub.
I reduced my trash by at least one bag per week and my recycle bin has a lot less cardboard at the curbside.
