We have implemented several measures to reduce our waste volumes: One is the efficient use of recyclable packaging. Wherever possible, we deliver our products in large containers that we take back, clean and reuse. For small containers, we use disposable packaging for logistical reasons. Symotion GmbH, our logistics services subsidiary, optimizes this packaging continuously in respect of both the economic and ecological criteria as well as product and occupational safety aspects. In 2015, we used 20 thousand tons of packaging material globally. Of this, 44 % was returned to us.
