achieved this by specially insulating the workshops, having a modern heating system and photovoltaic installations for power supply,” he says. “We are now seeking to transfer these positive experiences with energy-saving concepts to every other part of the firm.”


Energy becomes a global issue Zimmermann says AZO’s business is truly global – and so is the interest in energy efficiency and sustainability.


“Asia, for example, has already fully embraced sustain- ability. The focus is now on energy efficiency, conserva- tion of resources and environmental protection in all parts of the world. Ultimately it is all about gaining a competitive edge. And that also means keeping an eye on costs, he says. “We are finding that the emerging economies, too,


are becoming increasingly cost-conscious. They are no longer looking primarily at the cost of purchasing an

Germany is a world leader in plastics recycling. Data from the country’s Federal Environment Agency shows that in 2011 it generated some 5.45m tonnes of plastics waste and 99% of that was either recycled or converted into energy. So it is no surprise that Germany holds a prominent place among manufacturers of systems and equipment for recycling of plastics, or that those manufacturers are benefiting from increased environ- mental awareness across the globe. “Plastics recycling is growing enormously in importance and signifi- cance, particularly in China. The global shortage of raw materials, constantly rising cost pressures and huge quanti- ties of waste mean that the recycling market is expanding very rapidly,” says Jan-Udo Kreyenborg, managing director of plastics reprocessing machinery maker Kreyenborg. To some extent, he says this demand is being driven by big

driven by the realisation that recycling can help producers manage rising raw material costs. “Plastics converters all over the world are very keen to get their hands on cheaper raw materials. This

requirement can only be satisfied by resorting to secondary raw materials,” says Werner Herbold, managing director of size reduction technology developer Herbold Meckesheim. He reports particularly strong demand from countries that have not seemed greatly interested in recycling up until now, including the US, Canada and Mexico. German recycling machinery makers also benefit from the country’s decision to implement highly demanding waste management systems such as the Green Dot and Dosenpfand bottle deposit scheme. “Through its early introduction of recycling systems, Germany has come to be seen as a model in many parts of the world. We are, for example, pioneers in process technology for the recycling of plastic bottles or electronic waste,” says Peter Mayer, managing director of S+S Separation and Sorting Technology. ❙ www.kreyenborg.comwww.herbold.comwww.sesotec.com
