Turn your sustainability targets into engineering reality.

Stop leaving your energy, carbon, and ESG goals on paper. We provide the end-to-end commercial strategy and engineering delivery required to future-proof industrial operations across New Zealand and Australia.

A full-lifecycle partner for heavy industry.

Many advisory firms can write a high-level sustainability report, but very few can actually build those solutions on your factory floor.

Transitioning heavy industry requires a partner who understands both the financial realities of CapEx planning and the complex mechanical realities of process heat, refrigeration, and waste.

At DETA, our sustainability consultants work seamlessly with our engineers to bridge the gap between boardroom ESG targets and daily operations. Whether you are just starting your reporting journey or breaking ground on a major infrastructure upgrade, we provide the technical precision to execute on time, on budget, and without disrupting production.
