Materials
The Group’s most important raw materials are polymers (usually natural or synthetic rubber), and additives, such as softeners (oils), fillers (carbon black) and curing agents (sulfur and peroxides). Some of the substances used are classified as environmental and/or health hazards. Metal components are a key constituent in many of Trelleborg’s products. These are procured from other manufacturers.
In 2006, 350,000 tons of direct material was consumed, of which 68 percent comprised non-renewable material. Of the total amount of raw material, 4 percent comprised recovered waste material. Greater resource efficiency is one of the five main areas in the Group’s environmental policy. This implies that we endeavor to reduce raw-material consumption by minimizing waste and increasing waste recovery. This work is conducted continuously at our production facilities.
