D2W TECHNOLOGY

Symphony has developed over 25 years a biodegradable plastic technology which addresses the problem of persistent microplastics, by turning ordinary plastic at the end of its service-life into a waxy substance which is biodegradable. It is then no longer a plastic and can be bioassimilated in the open environment in a similar way to a leaf without leaving microplastics behind. The technology is branded d2w® and appears as a droplet logo on many thousands of tonnes of plastic packaging and other plastic products around the world, much of which has been recycled. In some countries, this type of plastic is mandatory for short-life plastic products.

D2P TECHNOLOGY

Symphony has also developed practical and cost-effective ways to upgrade plastic products to provide protection against bacteria, viruses, fungi, insects, odours and fire.  See www.d2p.net.

NbR TECHNOLOGY

NbR is made with natural minerals to reduce the amount of fossil-derived polyethylene or polypropylene used for making plastic products. The products can be recycled, but will biodegrade safely without leaving microplastics if they escape recycling and end up as litter in the open environment.

When NbR is used instead of normal polythene or polypropylene, it will reduce the amount of fossil-derived plastic in the product by 20%, as well as cutting CO2 emissions.
