At Graymark, every pilot starts with the same question: What waste stream has value that no one else can see yet?

From there, our team of engineers, chemists, and operators begin designing the systems that make recovery possible.

Understanding the waste

Our process begins at the source — on site with the client or facility generating waste. We analyse the material composition, current disposal practices, and potential chemical or energy value within that waste stream.

Whether it’s CCA timber residue, glycol runoff, or organic by-products, the first step is always understanding the waste at its most technical level.

Feasibility and recovery design

Once a viable opportunity is identified, Graymark engineers map the process pathway: collection, separation, refinement, and reuse.

Every step is designed for industrial reality — low maintenance, high uptime, and compatibility with existing systems.

We model economic return, waste volume reduction, and recovery efficiency before a single piece of equipment is built.

The result is a detailed feasibility report and early-stage process design, often developed in partnership with industry operators or regional councils. This data becomes the foundation for pilot system design and funding proposals.

Building for scale

Graymark’s recovery systems are designed to start small and scale fast.

We prototype, test, and refine each stage in controlled pilot environments, gathering operational and performance data to support wider deployment.

It’s an iterative process: measure, improve, and deploy again.

This approach allows us to reduce risk, accelerate learning, and ensure that every system we bring to market performs in real industrial conditions.

The people behind the process

Our strength comes from experience.

Three generations of the Vinsen family have worked in waste and chemical recovery, giving Graymark a deep operational understanding of what it takes to build systems that last.

That legacy drives our modern work — combining engineering expertise, environmental design, and commercial pragmatism to deliver solutions that perform today and scale tomorrow.

Closing the loop

Circular industry doesn’t start with policy or ideals — it starts with systems that work.

At Graymark, we build those systems from the ground up: one pilot, one process, one recovered litre at a time.
