Cleantech Pioneers: Circular Future.

The Sustainability  Horison 

The global plastic waste crisis demands more than incremental change — it demands a new paradigm in non-degradable - continually recycled waste plastic as the default feedstock.  

Kleentec21 is commercialising a world-first, 100% sustainable, low-cost, high-volume plastic platform powered by thermal solar energy and proprietary soundwave-driven hydrogen technology.

This is not recycling as usual.
This is industrial-scale circular transformation.

Commitment 

Built on the Siddons family’s 90-year legacy in Australian manufacturing — including the creation of iconic brands such as Sidchrome and Ramset Fasteners — and backed by five decades of cleantech leadership through Siddons SolarPlus, Quantum Energy and Siddons Solarstream, Kleentec21 brings together the world's most exciting circular economy of complimentary innovators, academics and industry partners in a race against time delivering faster - better results.
