Few in the alumina industry can quantify their sustainability claims – we set out to change that. We decided to prove it – partnering with CarbonChain, a global leader in carbon accounting technology, to verify what makes Alpha HPA different.
Our collaboration produced independently verified, audit-ready emissions data across our entire ultra-high purity product range. The result, as detailed in CarbonChain’s case study on Alpha HPA, shows how transparency can become a genuine competitive advantage.
VERIFYING OUR LOW-CARBON INNOVATION
Alpha HPA was founded on the idea that advanced materials can be produced without the environmental cost in traditional production. By applying our solvent extraction (SX) technology, we create ultra-high purity aluminium materials with a fraction of the emissions of conventional alumina production.
Working with CarbonChain, we set out to quantify that difference by backing our sustainability statements with verifiable data. Together, we completed a Product Carbon Footprint (PCF) assessment, aligned with GHG Protocol, ISO 14067:2018, and NGER standards.
The study covered our key products, mapping emissions from cradle to gate – raw materials through to finished product. CarbonChain’s methodology combined our operational data with asset-level supplier data to deliver a detailed, independently validated emissions profile.
“CarbonChain’s detailed product carbon footprinting has enabled Alpha HPA to cement our position as an industry leader in sustainability and communicate our commitment to ultra-high purity, low-carbon alumina production.”
– Rob Williamson, Managing Director, Alpha HPA
WHAT THE RESULTS CONFIRMED
The PCF analysis validated what we’ve built our business on:
- No reliance on high-carbon finished aluminium sheet metal feedstock, thanks to our licensed SX technology
- 100% renewable electricity powering manufacturing
- Near-complete reagent recycling, through our partnership with Orica
These findings, now verified by CarbonChain, give us and our customers complete confidence in the environmental credentials of our products.
“CarbonChain’s rigorous methodology gave us a clear, credible emissions profile – exactly what we needed to communicate our sustainability value proposition.”
– Derek Bogaert, Sales Marketing Manager, Alpha HPA
STRENGTHENING OUR POSITION AS A RESPONSIBLE SUPPLIER
The verified data supports our sustainability reporting and helped us earn an Ecovadis Silver rating, reinforcing our standing as a responsible, transparent supplier to high-tech sectors including semiconductors, LEDs and lithium-ion batteries.
More importantly, it enables us to identify further opportunities to reduce emissions and maintain accountability as we scale. Transparency isn’t a box to tick, it’s a discipline that drives improvement.
PROOF, NOT PROMISES
By partnering with CarbonChain, we’ve transformed sustainability from a statement into a system of proof. Their independent case study captures this journey in detail – how precise, auditable carbon data underpins everything we make.
As global markets demand evidence of impact, Alpha HPA continues to lead with verified, low-carbon innovation – delivering the world’s highest-purity alumina with the lowest possible environmental footprint.
