A tasty idea for pack­ag­ing

YOURS (UK) - - Consumer News -

How to pack­age food safely with­out plas­tic has long proved to be a night­mare for man­u­fac­tur­ers. But now many are tri­alling pack­ag­ing that is it­self made out of food! Last year Waitrose swapped from plas­tic pun­nets to re­cy­clable eco-trays made from card­board com­bined with dried toma­toes to pack­age its Duchy vine toma­toes. And we’re likely to see other shops fol­low­ing suit this year. But it’s not just toma­toes that could be turned into pack­ag­ing. Mush­room root, prawn shells and sea­weed have all proved to make good ma­te­ri­als for pack­ag­ing in re­cent tri­als, as has ca­sein, the pro­tein found in milk which, when com­bined with a mol­e­cule called glyc­er­alde­hyde, cre­ates a strong but biodegrad­able al­ter­na­tive to plas­tic. While not strictly made from food, nat­u­ral ma­te­ri­als such as wood pulp, com­post and bagasse – a waste prod­uct from the crush­ing of sugar cane – have also all been mooted as hope­ful sub­sti­tutes for plas­tic pack­ag­ing.
