Recycling – the eternal life cycle
People generate a wide variety of different waste types which pollute our environment for prolonged periods because they are excluded from natural material cycles. Valuable resources concealed in the waste are used only once before being irretrievably lost in incineration plants or landfill. It is an inescapable fact that, in the long term, we must take a leaf from nature’s book and adopt the life-cycle principle. The solution is to take a more considered approach to product design to ensure that all materials used circulate continuously in biological or technical cycles. So right from the start, we should be thinking about what will happen at the end – and focus on continuous product cycles.
Multipor is keen to recycle as many of the raw materials we use as possible on both economic and ecological grounds. So Multipor products are compatible with the life-cycle approach. This means that they can be fed back into the raw material cycle and used in the production cycle to create new Multipor or AAC products.
XELLA CLOSES THE LOOP WITH BIG BAGS FOR MULTIPOR WASTE
Xella Deutschland has developed a simple and effective means of closing the loop for Multipor mineral insulation boards. Much too good to throw away: Multipor mineral insulation boards have been a popular insulating material for many years, mainly due to their excellent thermal insulation properties. This is largely down to the air trapped in the pores. And air is known to be a very good insulator. But on most building sites, offcuts and waste end up in the skip. Although the quantities may be small, this waste creates disposal costs for the builder and is irretrievably lost as a raw material. Our search for an ecological and cost-effective solution led us to the Big Bag scheme. Customers can order a building site recycling pack along with their building materials – comprising big bags and coded closures together with a return label and accompanying leaflet.
Multipor offcuts are sorted and collected in big bags on site. The bags are then sealed with coded closures, placed on pallets and returned to the production plant. Here the waste is ground down and fed back into the production process.
Since introducing the Big Bag scheme, more than 412 tonnes of mineral insulation has been fed back into the loop within a year. Not bad, considering that 210 million tonnes of mineral waste is generated each year in Germany – around 60 percent of Germany’s total volume of waste. Another reason why the Multipor material loop is ecologically and economically valuable for the environment.
