Case Study 1: Two-pass
One California landowning company developed a two-pass removal system in a sawtimber/biomass harvest that optimized equipment utilization and transportation logistics. In one district, Sierra Pacific Industries typically divides operations into two phases, with non-saw log material removed first and saw log harvest undertaken later. In the chipping operationn phase, the biomass component is chipped and piled independently of the skidding.

Case Study 2: Two-pass, Post-harvest Entry
A Montana log trucker, John Jump Trucking, diversified into a business collecting, processing, and delivering (both to bio-energy and mulch markets) harvesting slash previously considered unmerchantable, combining technical innovation with astute market development.

Case Study 3: Two-pass, Collecting Logging Residue
An Idaho logging contract has developed an innovative collection and transportation method for gathering scattered logging slash and then processing and concentrating it into volumes more easily accessed by chip vans. Mick Buell's procedure enables more efficient on-site curing, optimum configuration of biomass piles for loading, and van access.
