Hardie Pacific is committed to reducing carbon emissions. With the global focus on greenhouse warming and the rapid increase in international carbon pricing, the race is on to find new forms of permanent carbon dioxide removal (CDR). Aotearoa NZ’s Mg0 endowed ultramafic rocks, notably Dunite and Serpentine, chemically react with CO2, forming stable minerals. This process has become an acceptable, permanent form of carbon removal. Our aim is to become the Southern Hemisphere’s major Carbon Sequestration hub.
Carbanz Limited, an Aotearoa NZ registered company, has created a public library for data relating to carbon sequestration in MgO rich ultramafic rocks, which chemically react with CO2 forming stable minerals, thus reducing/removing emissions from the atmosphere permanently, through either in-situ carbon mineralisation or ex-situ/offsite mineral carbonation. The source of CO2 can be derived either from polluting industries or extracted from the atmosphere. Mineral carbonates produced though the ex-situ process are ideal for producing a range of building and construction products, or alternatively can be used in a variety of other applications. Valuable critical elements are also potential by-products of the process including high purity silica and REEs.
Carbanz Limited is in collaboration with four Australasian universities, to provide an information platform on carbon sequestration that can be used by investors, polluting industries, media and other interested parties.
We need urgent new responses and actions to address the enormity of the climate change problem.
Weora Limited, another Aotearoa NZ registered company, holds 5 Mineral Permit applications across the full length of New Zealand: PPA60861 ‘Green Hills’, PPA60862 ‘West Dome, PPA60863 “Whakatu’, PPA60875 ‘King Country’ and PP60864 ‘Waitkati’ totalling 1,283km2. Aotearoa NZ is recognised as one of the worlds largest ultramafic rock deposits.
Weora plan to either:
- inject CO2 deep underground (in-situ) or
- quarry, crush and mix with CO2 (ex-situ) to form stable carbonate material suitable for industrial material manufacturing such as CO2 neutral cement, plasterboards and other construction materials.
This process is today naturally occurring wherever these ultramafic rocks are exposed at Green Hills, and West Dome, Southland, Fiordland National Park Red Hills and the Dun Mountain complex near Nelson.
Our established team in Aotearoa NZ is engaging with large CO2 emitters, Iwi, Government at all levels. Sampling and laboratory test work with research organisations is underway.
Carbozorb Pty Ltd
Carbozorb Pty Ltd, an Australian NSW registered company, holds 6 Mineral Exploration Licence applications: ELA6375 ‘Bingara’, ELA6376 ‘Boggabilla’, ELA6377 ‘Clarence’, ELA6383 ‘Manilla’, ELA 6401 ‘Coolac’, ELA6402 ‘Nyngan’, and ELA6447 ‘Nyngan South’ totalling 2,282km2.
Carbozorb is evaluating the potential suitability of surface and buried ultramafic rocks within the NSW Great Serpentinite Belt (GSB) and Coolac Serpentine Belt for sequestration of CO2 either through using direct air capture or emissions direct from polluting industries. The advantage of these deposits are that they are located in the high sun belt zones, suited for solar powered direct air capture (DAC) and sequestration.
The target commodities are Olivine and serpentine associated with buried ultramafic rocks.
Australian researchers have been studying the prospects for mining these serpentines for the past decade, crushing them prior to mixing with CO2 to manufacture various building and construction components.
