A new biodegradable plant pot has been developed as an alternative to the 350 million plastic trays used per year by nurseries and gardeners, Stuff reports. The product, developed by Pinehurst Associates with support from the Ministry for Primary Industries, is a pot that starts to biodegrade once put into soil and even acts as a fertiliser. Auckland Council trialled the planting of PolBionixpots in Waitawa Regional Park in Kawakawa Bay in August and further pots were planted at an Auckland school in October.
