The science is a mystery to me too, but am thinking about composting
leaves, which, if shredded, apparently only take a year or so to turn
into compost.

May be worth restricting your currently empty bin to shredded leaves

The composting time of leaves ius dependent on the type of leaves.
Beech,for example are very slow to break down.
