Plastic that degrades in seawater could be boon for cruise industry and others

Large volumes of plastic waste generated aboard military, merchant and cruise ships must be stored onboard, often for prolonged periods, until they make port. In the future, a new type of environmentally friendly plastic that degrades in seawater may make it safe and practical to toss plastic waste overboard, freeing-up valuable storage space, according to scientists at The University of Southern Mississippi (USM).
