PPS-GR : An innovation in waste heat recovery and CO 2 capture for corrosive environments
The industrial sector is a cornerstone of global economic development , responsible for producing essential goods and services . However , it also accounts for a significant portion of global energy consumption and greenhouse gas emissions . With growing global commitments to sustainability , industries are under increasing pressure to optimize energy use and reduce their environmental footprint . One of the most promising pathways is waste heat recovery , which captures and utilizes heat that would otherwise be lost in industrial processes . Despite its potential , waste heat recovery faces significant hurdles , especially at low temperatures where corrosion and fouling inhibit the performance of traditional materials .

Technoform , a specialist in thermally and mechanically optimized profile solutions , offers an innovative material , PPS-GR , to overcome these challenges . This advanced thermoplastic polymer with graphite filler redefines the possibilities of heat recovery and CO 2 capture in corrosive environments . Combining high thermal conductivity , corrosion resistance , and ease of integration , PPS- GR is unlocking new opportunities for sustainable industrial processes .
Unlocking the potential of waste heat Industrial waste heat represents an enormous but underutilized energy resource . According to Heat Roadmap Europe , waste heat from industrial processes could provide energy to power 100 million two-person households . A significant portion of this heat — about one-third — is at temperatures below 200 ° C . This low-temperature heat , often dismissed as too challenging or inefficient to recover , holds vast potential for reducing energy consumption and emissions if the right technologies are applied . The main challenge lies in recovering heat below the acid and water dew point , where flue gases condense , forming corrosive acids . Traditional materials used in heat exchangers , such as stainless steel or titanium , are often insufficient to withstand these harsh conditions . As a result , industries face frequent equipment failures , high maintenance costs , and suboptimal energy recovery rates . In 2016 , NACE International reported that the global cost of general corrosion amounted to USD 2.5 trillion annually . In power plants , where heat exchangers are vital for energy recovery , corrosion-related costs alone exceed USD 7 billion each year . These figures underscore the urgency of finding new materials capable of performing in these demanding conditions .
PPS-GR : a game-changing material Technoform ’ s PPS-GR is an innovative composite material designed to address the challenges of lowtemperature heat recovery in corrosive environments . Combining polyphenylene sulfide ( PPS ), a hightemperature-resistant polymer , with graphite , known for its excellent thermal conductivity and acid resistance , PPS-GR delivers unmatched performance in industrial heat exchangers .
