Many U.S. municipalities and communities are integrat- ing recycling programs in the management of their solid waste in order to minimize landfill requirements. The suc- cess of these recycling programs is strongly dependent upon the marketability of the materials set aside from the waste stream for recycling. The requirements for marketing re- cycled glass are well established and are highly dependent upon color sorting of the glass. Post-consumer plastics recycling is in its infancy and is experiencing rapid growth. Plastics container manufacturers and other users of recycled resins have stated that color sorting of post-consumer plas- tic containers can significantly expand the marketability of resins derived from these containers. Color sorting of glass and plastics containers for recycling is currently done by manual handsorting. The objective of the proposed Phase I research is to determine the feasibility for developing an automated color sorting process for post-consumer glass and plastic containers.
