Quadrant has launched a new recycling service for architects, designers and contractors which will reduce the number of unwanted folders going to landfill. The R4 initiative, which stands for 'return, reuse, recycle and reduce', promises that Quadrant will collect sample folders supplied by any carpet manufacturer and dispose of them in highest-value end-use recycling centres, avoiding landfill. Customers can return unwanted folders by freepost, using a simple online system to generate the returns label.
