Conclusions
The portable conveyor removed slash with minimal environmental impact. The system causes no soil disturbance other than foot traffic during setup, operation, and takedown. The tests showed the technical feasibility of conveying wood chips at a rate of at least 7 green tons per hour with minor modifications to chipper and hopper configurations. The system as demonstrated did not carry raw slash reliably, although other commercially available configurations might address these problems.
A conveyor carrying wood chips is at least twice as productive as one that is carrying raw slash. A 200-foot conveyor line could carry biomass to the roadside for about $40 per green ton in the form of slash or $20 per green ton in the form of chips.
