Abstract:
There is a need for alternative harvesting techniques to direct chipping. Mainly due to that direct chipping is a system that demands direct delivery of SRC when harvested. Alternative systems are bundle and billet harvesting, both systems generating a product that can be stored and delivered when needed by customer. The objective is to evaluate alternative systems as an option and complement to direct chipping. Costs were calculated for three systems from field to energy generation plant. Costs have been analyzed for three systems i) direct chipping ii) billets and iii) bundles. Both billet and bundle systems show higher costs than direct chipping, irrespective of field size. The analysis shows possibilities of lowering their costs. Billets and bundles can be stored for longer periods at field’s edge, unlike chips, which facilitates increased security of supply according to needs of energy plants. The most important measure for reducing costs for the studied billet system is increasing harvester capacity. For the studied bundle system, costs for collection in field and road transport need to be reduced, as example using more efficient systems for collecting bundles in field and by utilizing load capacity better during transport to plant.
