Abstract
A prototype rock separator designed to separate rocks greater than 2.5 cm was built and tested at Nicholson Murdie Machines Limited's operation. The prototype demonstrated that a rubber-belted conveyor can be used to separate rocks from woody material when operated with a side tilt and a speed and slope that are greater than normally used to transport wood waste. Rock separation rates greater than 90% with wood loss of 29% were achieved during the field tests. Average production rates of 8.8 tonnes per hour were achieved during prototype testing.

Abstract
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.

Abstract
This report gives the results of a field test and demonstration of a modified pit burner when burning logyard waste. The modification included the introduction of high pressure air in the base of the pit burner. The addition of underfire air resulted in reduced smoke emissions relatives to the standard pit burner with only overfire air. Based on field test results, potential cost and production scenarios were estimated.

Abstract
The objectives of this study were to provide an economic analysis of whole-log debarking and chipping systems having potential in Alberta, and to identify the most economic system for application in both portable and stationary yards. The study was undertaker by FERIC at the request of the Forest Industry Development Division of the Alberta Ministry of Forestry, Lands, and Wildlife.

Abstract
The objective of this study was to determine harvesting and processing methods that could economically utilize the stands of decadent cedar- hemlock in the interior of British Columbia. At present, existing surpluses or lack of demand for the main end products of these stands mean that they are unprofitable to harvest. Until these conditions change or harvesting modifications and incentives are introduced, it will continue to be uneconomical to harvest the stands. Recommendations are made regarding harvesting modifications and incentives.
