World-leading clean tech for a better future

We’re pushing the boundaries of clean technology as the first in the world to sustainably extract circular green metals from waste at scale.

Our Solution

Transforming waste into circular green metals

Low carbon & circular

We design commericial scale low carbon and circular technologies to produce green metals with as little environmental impact as possible.

Locally deployed

The low impact nature of our technology and approach means we can seamlessly deploy it in existing city infrastructure, addressing the problem where it starts.

Continuous innovation

Our advanced clean technology and investment in R&D means we continuously explore new waste streams and metals to extract.

Our Process

How we process e-waste

01

E-waste is prepared for processing

Waste printed circuit board components from the e-waste are weighed and milled into a fine sand consistency. This maximises the surface area enabling rapid metal recovery and guarantees data destruction exceeding NSA standards.

02

Copper is recovered 
through smart chemistry

Copper is recovered through a conventional electrochemical process, producing pure copper sheets ready to be reused.

03

Precious metals are recovered

Through our patented biotechnology, we recover precious metals in a manner that both concentrates and purifies them. The material recovered is then further refined to produce commodity grade gold.

04

By-products and chemicals are recycled or sold

Chemicals used are recharged and recycled within the process, or converted into by-products that have use in construction and agriculture.

Sustainability

What partnering with us means for the planet

01

Ethical sourcing

Feature one

Ethical sourcing

Our technology recovers value from a problematic waste stream in an ethical and sustainable way.

02

Low carbon

Feature two

Low carbon

Compared to traditional extraction methods, our biorefineries produce over 90% less carbon emissions.

03

Local processing

Feature three

Local processing

Having local biorefineries means that we can process waste onshore, removing the need to send it to landfill or export value.
