The recent decision by the UK government to lift tariffs on US bioethanol imports has sparked alarm bells across the country’s renewable energy and industrial gas sectors. Domestic producers like Vivergo Fuels and Ensus, which have invested heavily in the UK’s green energy transition, now face a significant threat from cheaper US imports that do not always meet the same environmental and sustainability standards.

But the issue isn’t just about market competition or local jobs. It’s about the integrity of the UK’s CO₂ supply chain, energy security, and long-term sustainability.

Why Bioethanol Matters for CO₂

In the UK, bioethanol production is closely tied to food-grade CO₂ generation. Plants produce CO₂ as a by-product when fermenting wheat into ethanol. This CO₂ is captured, purified, and used in:

– Food and beverage carbonation
– Meat processing and stunning
– Modified atmosphere packaging
– Healthcare (e.g., surgical tools sterilisation)
– Greenhouse enrichment

If these plants shut down or reduce output due to being undercut by US imports, CO₂ production will fall sharply.

What’s at Risk: A CO₂ Crisis Déjà Vu?

We’ve been here before.

When CF Fertilisers (formerly Terra Fertilisers) suddenly shut down its ammonia plants in 2021 due to surging natural gas prices, it caused a nationwide CO₂ shortage. The government had to step in with emergency funding to restart production temporarily, but the damage was done:

– Abattoirs suspended operations.
– Beer and soft drinks faced production delays.
– Fresh food supply chains experienced severe disruption.

The situation highlighted just how fragile and central CO₂ supply is to the UK’s critical infrastructure. Now, with bioethanol at risk, we’re heading toward a similar cliff edge—this time one that’s market-driven rather than energy-cost-driven.

Policy Blind Spot: Undermining Domestic Green Production

The UK government’s push for cheaper fuel via tariff-free US imports appears to contradict its Net Zero and energy security goals. American ethanol, often derived from corn and shipped across the Atlantic, comes with a higher carbon footprint than UK-sourced wheat ethanol.

Domestic plants like follow stringent sustainability standards and contribute significantly to the rural economy. Their closure would undermine years of investment in green jobs and circular economy infrastructure.

Why Biogas is the Sustainable, Secure Alternative

With the volatility in the bioethanol market and the historic unreliability of fertiliser-based CO₂ sources, the case for biogas has never been stronger. More than just an environmental solution, biogas offers superior energy security, operational resilience, and community integration.

Here’s why the future of the UK’s CO₂ supply is rooted in biogas:

1. Self-Powered and Energy Resilient

Most modern anaerobic digestion (AD) plants are self-sustaining, generating their own power using biomethane, a renewable gas produced during digestion. This means:

Plants don’t rely on national grid energy or fossil fuels, reducing exposure to external energy price shocks.
Operations can continue even during power disruptions or high-demand periods, offering a level of autonomy and continuity that fertiliser and ethanol plants simply don’t match.

This makes biogas plants not just green, but also operationally robust.

2. Locally Sourced Feedstocks = Strong Supply Chains

Unlike US ethanol which is shipped across oceans, UK biogas plants typically use locally sourced agricultural residues, food waste, and crops. This localized model ensures:

Shorter, more resilient supply chains—no international trade bottlenecks or long-haul logistics.
Tight integration with UK farmers—many AD plants are directly connected to farms, creating circular economies and boosting rural economies.
Less competition with global food supply—feedstocks are often waste products or non-edible crops like maize silage or rye.

The result? A reliable and community-supported feedstock stream that can be managed proactively, unlike gas-reliant or grain-sensitive bioethanol plants.

3. Built-In Crop Contingency and Stockpiles

Many UK biogas operators have developed sophisticated crop contingency plans to handle seasonal variation or poor harvests. These include:

On-site silage bunkers or clamps with years of feedstock stored in advance.
Diversified input streams from organic waste, energy crops.
Contracted supply agreements with local farms to guarantee consistent inputs, even during adverse weather or crop failure events. This level of planning gives biogas a major edge over bioethanol producers, who depend on consistent yields of high-quality wheat, and over CF-style ammonia plants that rely on volatile gas markets.

4. Environmentally and Economically Aligned

Biogas is not just a greener source of CO₂—it’s aligned with national policy goals:

Net Zero 2050: Biogenic CO₂ from AD plants is part of the natural carbon cycle and can even deliver negative emissions when paired with carbon capture.
Rural Development: AD plants provide farmers with secondary income, create local jobs, and support sustainable agriculture.
Waste Circularity: They help reduce waste, and produce nutrient-rich digestate for use as fertiliser.

What This Means for Pro Gases UK Customers

As a bulk CO₂ supplier rooted in green principles, Pro Gases UK is already ahead of the curve by sourcing from biogas plants. Here’s how we’re helping customers weather market uncertainty:

The Road Ahead

If domestic bioethanol production continues to decline due to market distortion, the UK will become increasingly reliant on foreign CO₂ sources—a scenario that threatens price stability, environmental targets, and food security.

But there’s still time to pivot as a und user of CO2.

Biogas is not only the more sustainable choice—it’s the more secure one. At Pro Gases UK, we believe this transition isn’t just inevitable. It’s essential.

At Pro Gases UK, quality is more than a promise — it’s a responsibility. We are proud to announce that we’ve achieved FSSC 22000 certification, marking a major milestone in our ongoing commitment to excellence in food safety and quality assurance. This certification builds on our existing ISO 22000 foundation and reinforces our role as a trusted partner in the food and beverage supply chain.

Why Food Safety Matters for a Gas Supplier

Our CO₂ isn’t just industrial-grade gas — it’s a critical food ingredient. It goes into carbonated beverages, food preservation, packaging, and chilling processes across the UK and beyond. That’s why food safety is not optional for us — it’s essential.

With FSSC 22000, we’ve formalised and strengthened our approach to food safety to ensure our CO₂ consistently meets the stringent standards expected by global food and beverage brands.

From ISO 22000 to FSSC 22000: Going Beyond Compliance

While ISO 22000 provided a strong base for food safety management, FSSC 22000 takes our commitment further. This certification, recognised by the Global Food Safety Initiative (GFSI), adds important requirements such as:

– Food defence and food fraud mitigation
– Enhanced supply chain risk management
– Strong emphasis on food safety culture
– Clear traceability and documented controls
– Greater auditability and accountability.

It’s a more robust, business-wide system that reflects how seriously we take our role in the food value chain.

It Starts with Our Inputs: Vetting Suppliers and Food-Grade Stocks

Our responsibility begins long before gas reaches a customer site. We conduct rigorous assessments of all upstream suppliers — including biogas producers and purification partners — to ensure they meet strict quality, hygiene, and traceability standards. We verify:

– Source material quality (e.g. crop-based feedstocks for biogas)
– Process integrity (no contamination from non-food-safe materials)
– Batch traceability from raw material to final liquid CO₂
– Independent lab testing and analytical validation.

Only partners who meet our food-grade criteria are part of our supply chain.

Traceability from Source to Cylinder/Tank

We maintain full end-to-end traceability, from the moment raw gas is collected at a biogas facility, through purification, transport, storage, and delivery. Our traceability system ensures:

– Every batch of CO₂ can be tracked to its origin
– All quality checks and test results are recorded and auditable
– Rapid recall procedures are in place, although never yet needed.

This gives our food and beverage customers confidence that the gas they use is not just safe, but fully traceable.

As the food and beverage industry grows more conscious of sustainability and traceability, the source of liquid carbon dioxide (CO₂) is under more scrutiny than ever. Used for carbonating drinks, preserving freshness, and ensuring food safety, CO₂ is critical to the sector. But not all CO₂ is created equal. At Pro Gases UK, we’re seeing a major shift towards green CO₂ sourced from crop-fed biogas plants — and for good reason.

Let’s break down why food-grade CO₂ from biogas is not only cleaner, but also smarter when compared to more traditional sources: ammonia production, bioethanol refining, and natural gas extraction.

1. Crop-Fed Biogas CO₂: Truly Circular and Sustainable

Biogas plants take organic materials — often crop waste, or agricultural byproducts — and convert them into renewable energy through anaerobic digestion. This process naturally produces CO₂ as a byproduct, which can be captured, purified, and liquefied for food and beverage use.

Why it matters:

– Carbon neutral: CO₂ released during use was recently absorbed by the crops, making it part of a short carbon cycle.
– Traceable origins: Customers increasingly care about where their ingredients and processing aids come from — biogas CO₂ provides a clear, clean story.
– Certified green: Our biogas-derived CO₂ is not only food-grade but also eligible for Vegan and Kosher certification — a growing demand among beverage brands.

2. Ammonia-Based CO₂: High Emissions, Heavy Industry

Most traditional CO₂ used in the UK has historically come from ammonia production for fertiliser. While this source produces high-purity gas, it’s tied to a highly carbon-intensive process that relies heavily on natural gas.

Challenges:

– High emissions: Ammonia production is one of the most energy-intensive industries.
– Vulnerability to shutdowns: We’ve seen recent supply chain chaos when fertiliser plants halted operations due to energy costs.
– Fossil-based: No pathway to carbon neutrality without major overhaul.

3. Bioethanol-Based CO₂: A Greener Option, But With Trade-Offs

Bioethanol CO₂ has become a semi-renewable alternative, as it’s produced from the fermentation of crops like corn or sugarcane. While more sustainable than ammonia-based CO₂, the feedstocks used often compete with food production or involve questionable land use practices.

Concerns:

– Indirect emissions: Crop production for ethanol can contribute to deforestation or water stress.
– Food vs fuel debate: Sourcing from food-grade crops can raise ethical and environmental questions.
– Less transparency: Difficult to trace origin and land-use practices across global supply chains.

4. Natural Gas-Derived CO₂: The Fossil Fuel Dilemma

Capturing CO₂ from natural gas processing is another common method, but this is inherently tied to the oil and gas industry — which runs counter to most food and beverage companies’ sustainability goals.

Downsides:

– Non-renewable: Extracted from fossil reserves with no regenerative loop.
– Increasing scrutiny: Beverage brands with strong ESG policies are steering clear of fossil-linked CO₂ sources.
– Greenwashing risk: Consumers are quick to question CO₂ sourced from fossil fuel infrastructure.

Final Pour: Biogas CO₂ is the Future of Refreshment

At Pro Gases UK, we’re proud to offer food- and beverage-grade CO₂ from 100% renewable, crop-fed biogas. It’s cleaner, greener, and already trusted by leading drinks brands looking to align with modern sustainability expectations.

In the beverage industry, carbonation is key. From soft drinks to sparkling water, carbon dioxide (CO2) is the crucial ingredient that gives beverages their fizz. However, as sustainability becomes a top priority, beverage manufacturers are seeking greener alternatives to conventional fossil-based CO2. This is where biogenic CO2, sourced from crop-fed biogas plants, offers a game-changing solution.

What is Biogenic CO2?

Biogenic CO2 is carbon dioxide that originates from biological sources, such as fermentation and anaerobic digestion. Unlike CO2 derived from fossil fuels, biogenic CO2 is part of the natural carbon cycle, meaning it does not contribute to a net increase in atmospheric CO2 levels. At Pro Gases UK, our biogenic CO2 is 100% sourced from crop-fed biogas plants, making it a truly renewable and sustainable option for the beverage industry.

Why Biogenic CO2 is Ideal for Carbonated Beverages

Beverage manufacturers require high-purity CO2 that meets food-grade standards to ensure quality and safety in carbonated drinks. Here’s why biogenic CO2 is the perfect match:

– Sustainability & Carbon Reduction: Since biogenic CO2 is captured from organic matter, it significantly reduces the carbon footprint of beverage production compared to fossil-based CO2. This helps manufacturers meet sustainability targets and carbon neutrality goals.

– High Purity for Beverage-Grade Quality: Biogenic CO2 undergoes strict purification processes to meet EIGA and ISBT standards for food and beverage applications. This ensures that drinks remain free from contaminants and maintain their crisp, refreshing taste.

– Vegan & Kosher Friendly: Our biogenic CO2 is certified vegan and kosher-friendly, ensuring it meets the dietary requirements of a wide range of consumers. This makes it an excellent choice for beverage brands looking to cater to diverse markets.

– Renewable and Circular Economy Benefits: By using CO2 from crop-fed biogas plants, beverage manufacturers support a circular economy. Organic materials such as food waste and agricultural residues are transformed into energy, with CO2 captured and reused rather than released into the atmosphere.

– Future-Proofing Supply Chains: Global CO2 shortages have highlighted the risks of relying on fossil-fuel-based sources. Biogenic CO2 provides a more stable and resilient supply, reducing dependence on industrial byproducts from ammonia and ethanol production.

The Industry Shift Towards Sustainable CO2

Major beverage brands are already making the shift towards low-carbon solutions to meet consumer demand for environmentally responsible products. By switching to biogenic CO2, manufacturers can enhance their brand image, align with net-zero commitments, and ensure a long-term, sustainable CO2 supply.

In recent years, the increasing concern over climate change and the need for sustainable energy sources has driven the exploration of alternative energy options. Biogas, a renewable energy source derived from organic waste, has gained attention due to its ability to generate electricity and heat. A by-product of biogas production is carbon dioxide (CO2), which has become an essential resource for various industries. This blog aims to shed light on the reliability of CO2 production from biogas plants and why it is worth the risk for businesses to transition from traditional CO2 sources.

Reliability of CO2 From Biogas Plants:

One significant advantage of CO2 production from biogas plants is its reliability throughout the year and its renewable energy source. Traditional CO2 sources, such as burning of fossil fuels, contribute to harmful greenhouse gas emissions and the depletion of finite resources. This outdated source of CO2 is susceptible to regular shortages and CO2 price increases. In contrast, biogas production from organic waste is continuously generated, meaning the source of biogas is practically infinite and ensures the availability of CO2 all year round. This abundant, sustainable, and uninterrupted supply is crucial for numerous industries and businesses that heavily rely on CO2 for their operations.

Essential for Businesses:

Food and Beverage Industry: The food and beverage industry heavily rely on CO2 for carbonating beverages, preserving food products, and preventing spoilage. The reliable supply of CO2 from biogas plants ensures that businesses in this sector can meet consumer demands consistently. By reducing dependence on traditional CO2 sources, companies can contribute to a more sustainable future while ensuring minimal disruption in their production processes.

Greenhouse Farming: CO2 is an essential component in greenhouse farming as it enhances the growth of plants and improves crop yields. By utilising CO2 produced from biogas plants, greenhouse farmers can enjoy a year-round, reliable supply. This reliability not only aids in maintaining consistent crop growth but also helps reduce the environmental impact associated with conventional CO2 sources.

Medical and Pharmaceutical Applications: The medical and pharmaceutical industries rely on CO2 for various applications, including anesthesia, cooling, and as a solvent. These sectors demand a reliable and pure source of CO2, making biogas plants an attractive and sustainable option. The consistency in CO2 supply ensures uninterrupted medical procedures and high-quality pharmaceutical products without the risk of shortages or production disruptions.

Environmental Benefits:

Moving away from traditional sources of CO2 is not only worthwhile due to its reliability but also because of the numerous environmental benefits. Biogas plants reduce carbon emissions by capturing and utilising methane, a potent greenhouse gas. By leveraging this renewable energy source and reducing dependence on fossil fuels, businesses can significantly contribute to mitigating climate change. Additionally, the use of biogas plants as a source of CO2 reduces the reliance on carbon-intensive industries and promotes a more sustainable approach.

In conclusion, the reliability of CO2 production from biogas plants is a convincing argument for businesses to consider the transition from traditional CO2 sources. The year-round availability of CO2, with limited shutdowns, provides a stable supply essential for industries relying on this resource. The food and beverage industry, greenhouse farming, and medical and pharmaceutical applications can benefit greatly from this consistent supply. Moreover, the environmental advantages associated with biogas plants, including reduced carbon emissions and sustainable energy generation, make it a valuable investment towards a more sustainable future. The decision to embrace biogas as a reliable CO2 source may involve some risks, but the potential benefits make it a risk worth taking.

Welding is a fabrication technique in which two or more parts are fused together with heat, pressure, or both to form a join that will hold when they cool. The weld quality, droplet transfer, current transfer, and, welding speed are all affected by the gas used.

The main goal when using gases to weld is to keep the weld pool as safe as possible. Other considerations include keeping welds clean on the opposite side of the seam, and shielding the arc from impurities such as air, dust, and other gases [1].

Gases used for Welding and Cutting Metals

There are two types of gases: inert and reactive. When in contact with other substances or temperatures, inert gases do not alter or generate change. Reactive gases, on the other hand, have the opposite effect. They react in a variety of ways, causing other substances and/or themselves to change state.

The following gases are utilised in welding and cutting processes [2].

Acetylene, propane, and butane are known as fuel gases
Oxygen, used with fuel gases and in small amounts in some shielding gas mixtures
Carbon dioxide, argon, and helium are known as shielding gases.

Argon

Argon is in charge of all the shielding agents on the planet. It has good penetrating power and can keep a consistent arc to make welding easier. It can be used to weld sheet metal using gas tungsten arc welding, because it provides a higher level of weld puddle control.

Carbon Dioxide (CO₂)

Pure CO₂ allows for an extremely deep weld penetration, which is advantageous when welding thicker materials. When combined with other gases, however, it generates a less stable arc and more splatter.

Compressed Air

Compressed air is utilised in welding in a variety of ways. Compressed air is commonly used to clear dust, swarf, and other dry materials from the workshop. Air nozzles attached to compressors with hoses spray air out to blow away dirt [3].

Oxygen

Oxygen is currently considered a raw ingredient in the welding industry. The production of modern steel necessitates a large amount of oxygen. In blast furnaces, Oxygen is required for flame enrichment in the pre-treatment of iron to eliminate faults in blooms, slabs, and billets.

Acetylene

Oxyacetylene welding, often known as gas welding, is a welding procedure that uses the combustion of Oxygen and Acetylene. When combined in the proper proportions in a hand-held torch or blowpipe, a relatively hot flame with a temperature of around 3,200 degrees is created. The high flame temperature makes acetylene a suitable choice for gas welding steels. Acetylene also produces a reducing zone, which is used to easily clean metal surfaces.

Helium

Helium is commonly employed as a welder shielding gas due of its high thermal conductivity, ability to deliver a wider and shallower application penetration pattern during the welding process, and ability to increase wetting of the weld bead. The welding sector, on the other hand, is facing some difficulties due to the impending helium scarcity.

Nitrogen

Nitrogen increases weld penetration and arc stability. Gas blends containing nitrogen can increase the mechanical properties of alloys containing nitrogen and prevent pitting corrosion and nitrogen loss from the metal.

Mixed Gases

There are many different gases to choose from, each of which excels in different areas and falls short in others. Mixed gases provide a useful balance for combining the strengths of several gases to create a harmonised product with outstanding outcomes.

Argon and CO2
Argon, CO2 and Oxygen
Helium and Argon
Argon, Helium and CO2
Argon and Oxygen
Argon and Hydrogen
Nitrogen and Hydrogen.

One of the most common mixtures of gases used for welding is Argon, CO2, and Oxygen. This gas mixture is used mostly by MIG welders who work with mild steel. Depending on the thickness of the metal, the concentration of CO2 will differ. The thicker the metal, the more CO2 in the gas mixture is required.

At Pro Gases UK, our most popular gases used for welding is pure Argon, and Argon mixes, with percentages of CO2 between 5%, 15%, and 20%.
