Abstract
Post-Consumer Wood (PCW) is a valuable resource that could substitute virgin wood in many applications. However, its integration into the wood processing chain requires detailed information on composition, content of contaminants, size, and shape. Here, PCW collected over eight months from three sorting facilities in southeastern Norway was analyzed for suitability in recycling. Shredded PCW from 24 samples was manually sorted based on material origin, analyzed for heavy metal concentrations, and the particle geometry was measured with an automated laser scanner. Based on the results, 39–67 % of the mixed PCW was made up by clean wood particles suitable for recycling. Wood-based panels within the PCW were not only a source of contaminants (adhesives, coatings) but also decreased the length-to-width ratio of the resulting particles and chips. The median heavy metal concentrations did not exceed the limit values issued by the European Panel Federation. However, individual samples and the fine fraction (< 8 mm) exceeded these limit values. Manual pre-sorting before shredding into chips increased the share of clean wood particles, prevented elevated fiberboard contents and significantly reduced heavy metal concentrations.
Abstract
European canker developing in young apple orchards may have been initiated in the nursery. Artifcial inoculation of Neonectria ditissima was carried out at time of heading back and manipulating of branch angles in the second year of nursery phase sized trees of 10 apple cultivars, either T-budded or grafted (with or without interstem). The trees were followed for two growing seasons and canker was found on 10% of the trees inoculated in wounds from heading back of the top shoots and on 24% of the trees inoculated in cracks from bending side branches. About 50% of those trees had visible cankers after the frst growing season, clearly showing the risk of delivering non-symptomatic trees to customers when infected in year two of the nursery phase. Commercial trees of six cultivars were inoculated either in wounds (cut surfaces or cracks from bending), or on nonwounded trees at the time of planting and followed for two growing seasons. Inoculation in crack wounds from bending side branches resulted in a higher number of infected trees than cut surfaces, and both had a signifcantly higher incidence than non-wounded inoculated trees and their non-inoculated controls (97%, 67%, 14%, and 3 to 5%, respectively). All trees with canker after two growing seasons had symptoms after the frst growing season. After two growing seasons, 50% of the trees with an infected scion had canker lesions on the rootstock. These results show that cankers discovered during the year of planting could have been newly initiated infections if the trees had been wounded and exposed to inoculum at planting.
