How Are Bio Based Coatings Changing Barrier Packaging
Packaging does more than hold a product. It also helps control contact with moisture, oxygen, grease, and other factors that can affect the condition of the contents. A paper food wrapper, for example, may need to resist oil while remaining easy to fold, whereas packaging for dry goods may require protection against moisture entering from…
Can PHA Plastics Turn Organic Waste Into New Materials
Organic waste is usually associated with disposal, composting, or energy recovery. Some of it can also provide carbon for producing PHA plastics. Food residues, agricultural by-products, plant processing waste, and similar materials contain organic compounds that microorganisms can use after suitable preparation. The conversion is not a direct change from waste to plastic. The incoming…

Wood processing rarely produces a single clean piece of material with nothing left over. Cutting, trimming, peeling, sanding, and other routine operations can leave behind bark, sawdust, chips, short fibers, small branches, and other plant-based residues. Forestry work can also produce material that does not enter conventional timber production. For a long time, these leftovers…
