Degraded marine environments and the loss of highly productive kelp forest
It is becoming increasingly evident that the health of our oceans is under threat. The loss of highly productive kelp forests is observed in ecosystems worldwide, including along New Zealand’s northeast coast to the top of the South Island—a clear sign of an unbalanced ecosystem.

Concrete is the backbone of the construction industry and one of the world's most versatile and ubiquitous products. Problematically, it creates 8% of global emissions and faces a significant challenge regarding its future viability with increasing pressure on nations to achieve climate targets and realise a low-carbon and circular economy.
Our Solution
Using natural resources to restore, not degrade, nature.
In New Zealand waters and beyond, the sheer scale of the loss of kelp forests requires urgent and systematic solutions. KiwiKrete aims to use natural resources to help accelerate the restoration and balance of marine ecosystems while simultaneously future-proofing concrete.
This has resulted in the development of a low-carbon concrete alternative that avoids the significant environmental impacts associated with conventional concrete, paving the way to regenerative practices that will make a lasting positive impact for current and future generations.
