Designed for recycling of post-industrial and post-consumer foam, a complete airlay line has been started up by Recypur. The line, which includes a blending line with 5 feeders, an Exel 1500 for fine opening, an Airlay Flexiloft+ with 2.20 m working width, a recycling machine and an oven, was delivered, installed and commissioned by international technology group Andritz AG, Graz/Austria.
The machinery was developed specifically for the bedding and furniture industry, with material heights reaching 20 cm and densities of up to 120 kg/m³. Experimental tests carried out together with experts from Andritz Laroche led to the conclusion that the mechanical method for recycling polyurethane (PU) is the most versatile and reliable.
With a capacity of 1.2 tons/h, this airlay line enables Recypur Eco SL, L'Alcúdia/Spain, to supply new mattresses made of industrial and post-consumer foam waste from old mattresses.
The process reduces environmental impact, increases self-sufficiency and eventually reduces the use of PU. It also allows multiple functional materials to be incorporated into the blend, such as flame-retardant, conductive and insulating fibers, among others.
