Increasing production and use of various novel plastics products, a low recycling rate, and lack of effective recy-cling/disposal methods have resulted in an exponential growth in plastic waste accumulation in landfills and in the environment To better understand the effects of plastic waste, Life Cycle Analysis (LCA) was done to com-pare the effects of various production and disposal methods LCA shows the specific effects of the cradle-to-grave or cradle-to-cradle scenarios for landfill, incine...
Collagen powder hydrolysates were reacted with a solution of commercial mimosa bark tannin extract. The mix- ture was prepared at ambient temperature and prepared at 80°C to determine what reactions, if any, did occur between the collagen protein through its amino acids and the polyphenolic condensed tannin. The reaction pro- ducts obtained were analyzed by matrix assisted laser desorption ionization time-of-flight (MALDI ToF) mass spectrometry. Reactions between the two materials did appear to ...
