What is the collection of the waste (once the bin is full) and replacement with empty bin costs?


This cost really isn’t translatable from region to region. There is 2 components to generating this costing:

Transport – point to point & return, i.e. your local rate per km x distance x 2, eg $1 per km x 60 kms (disposal point to farm) x 2 for return trip is $120 per bin

Disposal – this is widely variable.  In Australia, $100 per tonne is not uncommon for carcasses.  A 9m3 unit will on average hold 6 tonne, therefore it would be $600

Transport + Disposal = Cost of bin exchange
