CO₂ is one of the most expensive industrial gases to supply to regional businesses — not because it is scarce, but because it has to travel. AWE captures certified food-grade biogenic CO₂ directly from its anaerobic digestion facilities and supplies it locally to the wine, dairy, fruit packaging, and beverage industries that need it most.
Carbon dioxide is not a rare gas. It is produced in enormous quantities as a by-product of industrial processes around the world. But for regional food, beverage, wine, and dairy businesses in Australia and SE Asia, CO₂ is one of the most expensive inputs in their operations — because almost all of it has to be transported hundreds or thousands of kilometres from where it is produced to where it is needed.
CO₂ must be transported in heavy pressurised cylinders or cryogenic tankers by specialist logistics operators. The further it travels, the higher the cost. For regional businesses in the Murray-Darling Basin, the Goulburn Valley, or regional SE Asian markets like Cebu, the transport cost of CO₂ can rival or exceed the cost of the gas itself.
The result is a structurally expensive supply chain for a gas that regional industries cannot operate without — particularly in the wine, dairy, fruit packaging, and beverage sectors where CO₂ is used continuously and in high volumes.
Every AWE anaerobic digestion facility produces biogas containing approximately 35–45% carbon dioxide by volume. Rather than venting or flaring this CO₂ — as most AD operators do — AWE captures it, purifies it to food-grade specification, and supplies it to the regional industries located nearby.
The result is a fundamentally different supply chain for regional CO₂ buyers. Instead of waiting for a tanker that has travelled hundreds of kilometres, local food processors, wineries, dairies, and beverage manufacturers receive certified food-grade CO₂ produced at the AWE facility that processes the organic waste from their own region.
AWE's anaerobic digestion process produces raw biogas — a mixture of methane and CO₂. During biomethane upgrading, the CO₂ is separated and further purified through a dedicated food-grade processing stage. The result is a high-purity, certified biogenic CO₂ stream that meets food and beverage industry quality standards. Because it originates from organic matter rather than fossil fuel processing, it carries a biogenic classification — making it both renewable and traceable.
Biogenic CO₂ is carbon dioxide that originates from biological sources — in AWE's case, from the decomposition of organic matter through anaerobic digestion. It is chemically identical to fossil-derived CO₂ but carries a different carbon classification: biogenic carbon, not fossil carbon.
Biogenic CO₂ is the same molecule (CO₂) as fossil-derived industrial gas. At food-grade purity, it meets the same specifications for food and beverage applications — carbonation, modified atmosphere packaging, wine, and dairy.
Because AWE's CO₂ originates from organic matter rather than fossil fuel processing, it is classified as biogenic — not contributing to net fossil carbon emissions. Food and beverage buyers can use it as a certified lower-carbon CO₂ source.
AWE's CO₂ is purified to food-grade specification — meeting the purity, moisture, and contaminant standards required for direct contact with food, beverages, and wine. Independently certifiable under relevant food safety standards.
As a by-product of renewable biomethane production from organic waste, AWE's CO₂ stream supports buyers' sustainability reporting. The biogenic origin is verifiable through AWE's feedstock and production auditing processes.
Raw biogas from anaerobic digestion contains approximately 55–65% methane (CH₄) and 35–45% carbon dioxide (CO₂) by volume. When AWE upgrades this biogas to pipeline-quality biomethane, the CO₂ fraction is separated — not vented. It is then further purified through a dedicated food-grade processing stage to remove moisture, hydrogen sulphide, and other trace contaminants.
The critical point for buyers: AWE's CO₂ is not a waste stream. It is a deliberately engineered, separately certified product that AWE captures and purifies as a commercial output alongside biomethane. The capital investment in CO₂ capture and purification is built into every AWE facility design from the outset.
AWE's CO₂ offtake is structured to match each facility's location with the regional industries that most need a local CO₂ supply. Each project targets a different sector — wine, dairy and fruit packaging, and beverages — reflecting the dominant regional industries at each AWE site.
AWE's Wentworth/Mildura project has a CO₂ contract under negotiation with the regional wine industry — one of Australia's most significant wine-producing regions, spanning the Murray-Darling Basin from Mildura to Wentworth. Regional wineries and wine processing operations are major consumers of food-grade CO₂ throughout the year.
AWE's Cobram project targets the Goulburn Valley's dairy processing and fruit packaging industries — two of the most CO₂-intensive food manufacturing sectors in regional Victoria. The Goulburn Valley is home to major dairy factories and fruit canneries that consume CO₂ for modified atmosphere packaging, refrigeration, and processing applications.
AWE's Cebu project targets the regional Philippines beverage manufacturing sector. In regional SE Asian markets like Cebu, food-grade CO₂ is primarily imported or trucked long distances — making locally produced biogenic CO₂ from AWE's facility a commercially compelling alternative for beverage manufacturers who require consistent, reliable supply.
For regional food, wine, dairy, and beverage businesses, switching to AWE's locally produced biogenic CO₂ is not primarily an environmental decision — it is a commercial one. Local production fundamentally changes the cost structure, supply reliability, and sustainability credentials of their CO₂ supply.
CO₂ produced at the AWE facility near your business eliminates the long-haul transport cost that drives regional CO₂ pricing. The shorter the supply chain, the lower the delivered price.
Local production means no exposure to long-distance logistics disruptions, driver shortages, or tanker availability constraints. AWE's continuous 24/7 production provides a consistent, predictable local supply.
AWE supplies CO₂ under long-term offtake agreements — providing price certainty and supply security over the contract term, replacing volatile spot market pricing.
AWE's biogenic CO₂ replaces fossil-derived CO₂ with a certified biogenic alternative — supporting buyers' Scope 3 emissions reduction targets and supply chain sustainability commitments.
AWE accepts organic waste from the same regional food industries that receive the CO₂ — creating a closed-loop system where waste from one business becomes an input for another's operations.
In regional SE Asian markets like Cebu, where food-grade CO₂ is primarily imported, AWE's local production provides supply independence that imported CO₂ simply cannot offer.
| Factor | Conventional regional CO₂ supply | AWE local biogenic CO₂ |
|---|---|---|
| Transport distance | 100s–1,000s km by specialist tanker | Local — produced near point of use |
| Supply chain risk | High — logistics, driver, tanker availability | Low — continuous local production |
| Price structure | Spot or short-term — volatile | Long-term contract — price certain |
| Carbon classification | Fossil-derived — adds to Scope 3 emissions | Biogenic — renewable credentials |
| Regional availability | Dependent on logistics network reach | Available at AWE facility — local |
| Origin traceability | Fossil fuel or ammonia production by-product | Certified biogenic — traceable organic source |
AWE's CO₂ is purified to food-grade specification at each facility — meeting the purity, moisture, and contaminant standards required for wine, dairy, fruit packaging, and beverage applications. Independent certification and quality assurance are built into AWE's CO₂ production process from the outset.
CO₂ purified to meet food-grade specification — high purity methane and moisture removal, sulphur compound removal, and trace contaminant testing before supply
Origin certified as biogenic — traceable through AWE's feedstock auditing and biogas mass balance accounting, independently verifiable
Every AWE facility includes a dedicated CO₂ capture and purification system — not an afterthought, but an engineered product output from day one of facility design
AWE's CO₂ output is continuously monitored during production and tested before supply — ensuring consistent quality across the supply agreement term
