Transport guidelines for wood residue for Bio-fuels

In any system for delivering wood residue as bio-fuels from forests or wood processing sites, transport is a key factor and contributes significant cost. Transport cost as a percentage of delivered cost can vary from ~12% (5 km haul) to ~60% (150 km haul) depending on the transport distance.
Optimising transport systems on medium (50 km) to long (100 km) haul transport is therefore critical to minimising costs.
