PU rigid foam is easily recyclable

LINIREC building panels – for the sake of the environment
During manufacturing and installation of LINITHERM insulation systems, valuable PU rigid foam waste and leftovers are generated. These are much too valuable to be thrown away.

Basically, we have two options for recycling PU waste:

1. Material recycling – benefits instead of disposal
In connection with a new delivery of LINITHERM insulating panels, clean PU rigid foam waste can be returned in special bags provided by us. Together with milling scrap and cut-offs from manufacturing, the waste is recycled into new panels.

All remnants of foil and fleece are removed from the PU rigid foam waste before being shredded and pressed into pellets. The pellets are then finely ground, and using the pressure-bonding process, they are shaped into new high-grade LINIREC building panels for reuse on building sites for various purposes.

2. Energy recycling – recovering heating energy
Energy recycling is the best method for dealing with contaminated PU waste removed during demolition, conversion or refurbishment. This modern and gentle technology meets all the requirements for environmental and health protection.

The thermal energy of PU waste is also recovered in waste-to-energy plants without producing harmful emissions. The average calorific value of PU rigid foam is 27 MJ/kg, which is about equal to the value of black coal.

Material recycling and energy recycling are the ecologically best methods for disposing of PU rigid foam waste, the key to responsible waste management, and an important contribution for resource conservation.
