Frost and compost

[mtbc]

Our recent weather has been sunny and frosty. One of our plastic bins outside is for food and garden waste and I have noticed that the bottom portion of it, corresponding to the filled part, does not have frost on the outside. I wonder if even in these freezing temperatures there is enough biological activity occurring inside to generate heat that melts or prevents the frost.

Yeah, composting is exothermic.
