Symphony is a world leader in the development and marketing of additives and masterbatches to make plastic products better.


Better at Protecting

d2p (designed to protect) is a family of specialist additives, including antimicrobial, insect and rodent repellents, odour and ethylene adsorbers, oxygen scavengers and flame retardants designed to protect and enhance plastic products.


Better for the Environment

Our d2w oxo-biodegradable plastic masterbatch is a scientifically proven technology which can be added to ordinary plastic to make it degrade and biodegrade just like nature’s wastes,  if it escapes into the open environment –  on land or sea.   Perfect for single-use plastics and packaging. Products made with d2w have all the benefits of conventional plastic, but without the environmental consequences associated with it.


With over 25 years’ experience in helping our customers improve and enhance their products, Symphony’s trademarks represent not just a supply of additive or masterbatch, but a whole system aimed at adding value to every participant in the supply chain – right through to the end user.

Proves oxo-biodegradable technology works in the marine environment

Symphony Environmental are very pleased to announce the successful conclusion of the 5-year Oxomar Study sponsored by the French Agence National de Recherche.

This study provides further comprehensive and reliable scientific data on the performance of d2w in the oceans, and proves, degradability, biodegradability and non-toxicity.  The study had a multidisciplinary approach including physics, chemistry, and biology.

Analysis of the composition of plastics to evaluate polymer stability and degradation using industry standard ageing and polymer characterisation techniques.
