    Description

    Spectral transmittance measurements on aspen, sugar maple, and loblolly pine wood and bark chips resulted in peak wood-to-bark transmission ratio ranges from 10 to 50. Preliminary segregation results from an experimental photosorter indicate than 70 to 80% of the wood fiber can be recovered with less than a 2% bark content.
