Upcycling Waste FAQs
What type of waste are used?
1
Sustainability Precincts accept residual household and commercial waste - the material typically found in red or green general-waste bins. This is waste that most people assume can’t be recycled and would otherwise be sent to landfill.
Typically, over 75% of the waste content that is upcycled is organic contributing to a suite of low carbon products able to be produced.
How does the upcycling process work?
2
Waste is fed into the top of an oxygen-starved HPAG unit – picture an 11-metre-high wine bottle – and heated in the closed cylinder. Gases are molecularly separated and extracted from the top, while remaining solids exit the base of the unit as a solid rock-like product (i.e. no ash or toxic residues). Oxygen starved, combustion and large volumes of gases do not arise as with incineration. The captured gases are upgraded, cleaned and refined to produce Grade A+ hydrogen and CO₂ suitable for a variety of end market pathways.
How is this different from incineration?

Incineration burns waste in an oxygen-rich environment, producing large volumes of flue gases and leaving about 20% of the material behind as ash. Typically, around 3.3 times more flue gases are produced with incineration than HPAG. Incinerators are built to generate heat and steam, which are then used to drive turbines that produce electricity, and in colder climates, district heating for communities.
When e-waste is recycled, valuable minerals are separated and reused. Upcycling follows the same principle: using molecular chemistry to separate valuable hydrogen, carbon and oxygen for reuse.
As a gasification and pyrolysis process, HPAG does not combust waste. Instead, it captures gases such as CO₂ rather than releasing them and can combine that captured CO₂ with hydrogen to produce products like ethanol, methanol or Sustainable Aviation Fuel (SAF).
HPAG’s efficient process delivers significantly higher energy potential than incineration and provides a practical pathway for carbon capture and reuse.
What makes Xseed Solutions’ approach different from traditional waste to energy or recycling processes?
4
Our Sustainability Precincts use Hydrogen by Plasma Assisted Gasification (HPAG), an advanced recycling technology. HPAG is unlike traditional incineration which burns waste, emits carbon dioxide and leaves a residual ash. Instead, the HPAG process produces clean, hydrogen-rich gas, captures the carbon dioxide, and can generate renewable low carbon fuels.
High energy and capital efficiency deliver greater value and lower operating costs compared with traditional incineration methods.
Sustainability Precincts can also operate as independent micro-grids, strengthening local energy resilience. As an end-to-end solution, we have engaged with various technology providers to manufacture, distribute and dispense the end products to customers.

What is the long term vision?
5
We regenerate resources to live locally.
Our ambition is to develop an all of Australia and New Zealand offering of affordable, low carbon fuels and refuelling solutions to decarbonise a range of vehicles, whether by road, air, rail or sea. This is achieved through a network of Sustainability Precincts connected to hydrogen and electric refuelling stations, creating transport green corridors across Australia and New Zealand.
As the technologies are modular, we can scale with community circular economy outcomes, waste volumes and end-product demand.
How can industry partners and investors learn more?

We welcome discussions with councils, governments, industry partners and investors interested in developing Sustainability Precincts or understanding how the technology can support local waste, energy and emissions goals.
Xseed Solutions can provide technical briefings, project scoping support and partnership pathways.
