UK-based Tri-Star Packaging has introduced foodservice kraft boxes coated with Notpla, an innovative, sustainable material made from seaweed. Notpla decomposes in less than six weeks in a home composting environment and does not require any special conditions to degrade. The Notpla coating is made of a highly renewable resource, brown seaweed, which grows up to 1 metre per day. Seaweed doesn’t compete with food crops and doesn’t need fresh water or fertiliser. The kraft boxes are manufactured in the UK from sustainable sources which can include up to 25% grass. The method of production for the boxes also has a reported much reduced carbon footprint compared to standard board manufacturing, saving over 250kg of CO2, and 3,000 litres of water per tonne of carton board. The boxes are said to be suitable a range of foods from fast foods such as burgers and fries or dry curries, Notpla boxes are available in two sizes – 738ml (26oz) and 1307ml (46oz).
