Innovative global commercial flooring manufacturer Interface has successfully created the world’s first carbon negative tile thanks to process technology designed and supplied by IPCO.
Interface CQuestBioX tiles feature a new type of backing that incorporates a high concentration of carbon negative materials including recycled tiles, scrap from in-house processes and selected bio-based additives. The company’s objective of producing a carpet tile that actually stores carbon – reducing the amount of carbon dioxide in the atmosphere – also involved re-engineering key manufacturing facilities.
The company has been at the forefront of the drive for increased sustainability for more than two decades and in 2019 became the first global manufacturer to ensure that all its flooring products are now carbon neutral or better across their full life cycle. These outstanding credentials have seen Interface flooring selected by environmentally-conscious companies around the world, including some of Silicon Valley’s biggest names.
Interface began its remarkable journey towards ‘Mission Zero’ in 1994 when founder Ray Anderson was asked by a customer, “What’s your company doing for the environment?”
Realising that he couldn’t answer this question, Ray experienced an epiphany and committed Interface to a series of aggressive sustainability targets. This new course focused on reducing impact in three key areas of the business: its factories, products and suppliers, with the aim of making Interface the world’s first environmentally sustainable – and, ultimately, restorative – flooring company.
Such was the progress achieved that in 2019 the company announced Misson Zero success ahead of its 2020 target and set its sights even higher with Climate Take Back, an initiative that goes beyond climate neutrality with the aim of reversing global warming. In practical terms this means designing products that create “a positive impact on the world”. The new CQuestBioX tiles are a tangible result of this work and the first products to actually benefit the environment.
Interface full CQuest backings line is produced on IPCO ScatterPro and ThermoPress systems. ScatterPro is a precision scattering technology used to deposit bulk materials in a consistent layer before being formed by pressure and/or heat in a ThermoPress system.
A modular design allows multiple stages to be incorporated into one continuous process.
One of the most challenging aspects of the production process is the handling of the scrap material, which has a high fibre content. This has the potential to cause ‘clogging’ in certain types of systems, but the design of IPCO ScatterPro means it can be deposited without problems.
Once the material has been scattered, it is heated to melting point. A non-woven glass fibre scrim is then laid on top and a second layer of recycled scrap deposited to impregnate the material as it passes through a second heating stage, creating the finished backing. Finally, the carpet upper is unwound and laminated to the backing.
“IPCO has long been an enabler of the Interface journey. We have great confidence in IPCO machinery and service”, says John Bradford, Interface Chief Science and Technology Officer. Interface installed their first ThermoPress line in 2004 and has recently begun production on a second. The new system is capable of running at up to 20 metres a minute, meeting Interface requirement for maximum process efficiency.
