Symphony Environmental are a relatively small company, their office is near Elstree Studios where the 1st Superman movie was filmed. They\'ve found an alternative to harmful plastics by developing an additive called d2w to put into the plastic at the extrusion stage.

This is different from biodegradable, which needs a biologically active environment to help it break down. Dairy free, Gluten free, Organic, Wheat free
