Si-ZERO is a global sustainability initiative led by Swinburne University of Technology, uniting partners across Australia, India, Indonesia, and the United States.
"Our mission is to foster collaboration between research, industry and government to accelerate circularity and build a sustainable, future-ready solar ecosystem."
By integrating innovative recycling, processing, and clean-technology solutions, we transform end-of-life solar panels into valuable resources, supporting a sustainable and resilient renewable-energy supply chain.







Mechanical and Heat Pre-Treatments of Solar PV Panel
Partnership: SUT (Australia), Remind (Indonesia), UGM (Indonesia), BRIN (Indonesia) We develop efficient pre-treatment processes that mechanically and thermally separate solar PV components for high-value material recovery. By improving delamination, glass liberation, and EVA removal, this program lays the foundation for scalable end-of-life PV recycling solutions

Slag Optimisation & Distribution Measurement
Partnership: SUT (Australia), IIT Hyderabad (India) We engineer high-performance slag systems through advanced modelling and property measurement to support cleaner and more efficient silicon refining. This program provides the thermodynamic insights and slag behaviour data required for next-generation electro-slag and molten-oxide refining technologies.

Blue Laser Melting & Hydrometallurgical Processing for Ag Recovery
Partnership: SUT (Australia), UGM (Indonesia), BRIN (Indonesia) We advance selective blue-laser melting technologies to cleanly detach metallic layers from PV cells, enabling high-purity silver extraction. Combined with targeted hydrometallurgical processing, this process unlocks efficient recovery of critical metals from waste PV modules.

Zero-Carbon Silicon Electrochemical Production & Refining
Partnership: SUT (Australia), Sadoway Labs Foundation (USA), IIT Hyderabad (India), Greenko (India) We advance new pathways for producing and refining silicon with a significantly lower environmental footprint. This program brings together innovative electrical and slag-based refining approaches to create cleaner, more efficient alternatives to conventional silicon manufacturing.
