I've used a plastic bin with several holes done into it as a composting container. The content are all veggies and fruit leftover.
The compost gives out excess water (called leachate / compost tea). see hotbin leachate
I'm not sure about the color, but it does smell a bit, and that water gets absorbed by a large tub of soil beneath, which is compost collected from previous cycle, and is supposed to be used as a fertilizer.
Normally, we wait for that compost to dry up before using it, but is it harmful to use the wet compost mix with leachate already present. Is drying it up enough in open air to let it be used as fertiliser, or we need to wash it up before using?
