... I'm building a wooden compost bin ... and am worried that it will rot as
quickly as the compost ... OK, not quite ... so I guess I need to treat the
wood ... garden organically, so wonder what type of preservative would you
recommend ? Any info appreciated.

Composting material will not accelerate the rotting of a bin's untreated
timbers, but unless they are hard wood they will deteriorate in 3-5
years in most garden applications. You could increase their life span by
lining the bin with a PVC sheet, or other protective membrane.
