Webinar title: Flash Joule Heating Technology: Solid Waste Valorization and Pollution Remediation

Speaker: S.-T. Res. Bing Deng

Time: September 17, 2025 (Wednesday) 10:00

Venue: Room 200, New Environmental Building

Inviter: Zehui Li, Ling Zhao

Abstract:

Electrification is one of the primary technological pathways for reducing carbon emissions and achieving the dual-carbon goals. As a highly energy-efficient electric heating technology, Joule heating holds promise as a replacement for traditional energy-intensive and high-carbon-emitting processes. This presentation will explore the principles, equipment, and broad application potential of Flash Joule Heating (FJH) technology. FJH employs pulsed current discharge to rapidly and directly heat materials to target temperatures, offering high-temperature processing capabilities, extremely fast heating and cooling rates (>102 °C/s), ultra-short processing times (milliseconds to seconds), and near 100% energy efficiency. In this presentation, we will introduce the wide-ranging applications of FJH technology in resource recycling and environmental remediation, including the upcycling of solid waste, efficient recovery of strategic critical metals, and highly effective removal of heavy metals and organic pollutants.
