Induction or Joule Heating for Waster Polymer Upcycling 

Annually, the world produces approximately 400 million tons of plastic waste, a number projected to increase significantly in the coming years. Currently, the industry relies mainly on two methods for treating waste plastic: incineration and catalytic pyrolysis. Incineration, while widely used, has several drawbacks including the emission of large quantities of CO2, the release of toxic gases, and limited energy recovery options. In contrast, catalytic pyrolysis offers a more sustainable pathway by converting waste plastic into hydrogen-rich fuels, aligning with the principles of a circular economy.

However, traditional thermal pyrolysis technologies encounter significant challenges such as low hydrogen yield, poor selectivity, rapid catalyst deactivation, and high energy requirements for maintaining reactor operations. These limitations underscore the critical need for advanced pyrolysis technologies that can achieve higher hydrogen yields and selectivity, operate at lower temperatures, and consume less energy, thereby enhancing the efficiency of plastic waste upcycling and contributing to carbon neutrality efforts.

Our team is dedicated to pioneering innovative solutions in this field. We are developing two novel processes aimed at upcycling waste plastic into valuable products such as hydrogen, monomers, and jet fuel. The first process, magnetic induction pyrolysis, utilizes electromagnetic fields to rapidly heat the waste material, enhancing the breakdown of polymeric chains and facilitating the efficient extraction of hydrogen and other valuable products. The second process, rapid joule heating, applies an electric current directly to the waste plastic, achieving high temperatures in a controlled manner for swift and effective pyrolysis.

These cutting-edge processes not only address the environmental issues posed by plastic waste but also produce high-concentration hydrogen and high-value-added nano-carbon materials and jet fuel. Through these initiatives, our team is not just tackling the challenge of plastic waste but also forging pathways towards sustainable industrial practices that support global environmental goals.
