Field tests were conducted to determine the cost and productivity of a preproduction prototype model of a container system used to recover roadside biomass in mountainous terrain. The system recovered 82 m**3 of biomass per eight-hour shift. Load size averages 20.5 m**3 with a cycle time of 2 hours from the tests it is conservatively estimated that the recovery cost will be $8.32/m**3. With a production model of the container system fully integrated into the logging process it may be possible to achieve costs of $4.55/m**3. The cost of the conventional system (logging truck and choker skidder) used to recover roadside biomass is 15.51/m**3.
