Opacity is a foundational issue for processors of secondary material as they operate with limited material visibility, leading to hazard-related fires, downtime, and loss of downstream material provenance. True material visibility has remained an unsolved problem in the industry, given that the issue is predicated on an ever-evolving secondary material stream. Material composition can vary by time of day, season, municipality, city, and much more, and material depth (i.e. 鈥渂urden depth鈥�) makes it impossible to obtain accurate information on a facility鈥檚 material stream with conventional camera equipment.
