TECHNICAL PAPERS & USE CASES
Proving our confidence
The clean critical minerals we produce have application across a broad range of essential industries. Our technical papers provide detailed analysis of these applications, with specific industry standards and benchmarks to demonstrate the benefits Aspiring Materials critical minerals offer. Our use cases prove real-world application meets the expectations we set and affirms our confidence that the critical minerals we produce are up to the task.
MAGNESIUM HYDROXIDE
Wastewater treatment
Wastewater treatment is responsible for 1-3% of global greenhouse gases, with ~70% of those emissions comprising methane and nitrous oxide gases and the remainder being biogenic carbon dioxide (CO2).
​
Aspiring Materials has proven magnesium hydroxide can mineralise CO2 and store it as a carbonate permanently.
In this paper, we propose two carbon dioxide removal technologies using magnesium hydroxide that could remove ~40kg CO2 per capita each year with potential to lead to overall net-negative wastewater treatment emissions.
MAGNESIUM HYDROXIDE
Carbon dioxide mineralisation
Removing carbon dioxide emissions from heavy industry is a challenge that requires strategic balance against lifetime value of operational infrastructure and production performance. These industries are hard-to-abate because the processes require high heat that can (at this point) only be met by burning fossil fuels.
​
The fast moving consumer goods (FMCG) manufacturing sector is not hard to abate, but many operations still require high heat from fossil fuels or LPG, and burning these produces CO2 emissions that are released into the atmosphere.
​​
Aspiring Materials was a top 10 finalist in the 2023 APAC Greenhouse accelerator programme run by PepsiCo, a leader in the FMCG industry. Following the programme, PepsiCo invited Aspiring Materials to run a carbon mineralisation demonstration at their Bluebird production site in Wiri, Auckland, New Zealand.
​
The demonstration allowed us to prove that our magnesium hydroxide can capture and mineralise CO2 emissions from an industrial flue with little more than a bolt-on capture system (shown in the image on the left), our amazing magnesium hydroxide and water.
​
When CO2 is reacted with magnesium hydroxide and water, it is mineralised into magnesium carbonate. This results in a stable, permanent way to store CO2.
