Strategic Methodology For Advancing Food Manufacturing Waste Management Paradigms, Kurt A. Rosentrater
Kurt A. Rosentrater
As manufacturing industries become more cognizant of the ecological effects that their firms have on the surrounding environment, their waste streams are increasingly becoming viewed not as materials in need of disposal, but rather as resources that can be reused, recycled, or reprocessed into valuable products. Within the food processing sector there are many examples of value-added use of processing residues, although many of these focus solely on utilization as livestock feed ingredients. In addition to livestock feed, though, many other potential avenues exist for food processing waste streams, including food grade as well as industrial products. Unfortunately, the challenge …
