Imagine you're a manufacturer in the Waikato. Your energy costs have climbed 30 percent in two years. You've watched competitors close their doors — another well-known New Zealand food company shutting sites just last month. You're told relief is coming: a billion-dollar LNG import terminal at Port Taranaki, shipping liquefied gas from the other side of the world.

Then global LNG prices spike overnight. Supply disruptions, shipping delays, and international market volatility send costs soaring — exactly the kind of shock that New Zealand's new import terminal is supposed to protect against.

That manufacturer in the Waikato just learned something the hard way: energy security cannot be imported.

Two Announcements. One Question.

In March 2026, two things happened that should fundamentally shift how New Zealand thinks about energy:

First: The government confirmed its commitment to a billion-dollar-plus LNG import terminal at Port Taranaki. The facility is designed to backstop our electricity system during dry years — but it also locks in decades of dependence on international fossil fuel markets and prices set by forces we cannot control.

Second: On March 17th, GasNZ released its Biomethane Strategy and Action Plan, laying out a pathway for biomethane to meet half of New Zealand's natural gas demand by 2050. The same day, the Bioenergy Association published a direct call to action: New Zealand needs home-grown energy solutions, and bioenergy is ready to deliver.

The contrast could not be sharper. One path sends billions offshore. The other turns our own waste into energy. The infrastructure is already in the ground — the question is what we choose to put through it.

Biogas Is Not Alternative Energy. It's the Missing Piece.

The public debate keeps framing this as LNG versus renewables — fossil pragmatism against green ambition. That's a false choice, and it obscures the most practical energy pathway available to New Zealand right now.

Biomethane produced through anaerobic digestion of organic waste is not speculative. It doesn't need breakthroughs. It is chemically identical to natural gas, flows through existing pipelines, and is scaling rapidly around the world:

• The European Union produces over 170 petajoules of biomethane annually — more than the entire gas consumption of Belgium, Denmark, and Ireland combined.
• Denmark has replaced over 40 percent of its natural gas with biomethane from agricultural waste, targeting 100 percent by 2035.
• In Queensland, Kalfresh just secured A$80 million to build Australia's first integrated food and energy precinct — converting farm waste into renewable gas, electricity, and fertiliser. Enough to power 31,000 homes.
• New Zealand's own gas reserves plunged 27 percent in 2024, with production expected to drop below 100 petajoules per year by 2026 — earlier than anyone forecast.

Biogas doesn't depend on international shipping lanes. It isn't subject to global price shocks. It is produced locally, from waste streams that already exist, and it strengthens regional economies rather than draining capital offshore.

The infrastructure is already in the ground. The question is what flows through it.

What We're Building at Alimentary Systems

This is exactly the problem we set out to solve.

Our Bioenergy Resource Recovery Plants (BRRPs) use a patented biomimicry-based co-digestion process that mirrors the bovine digestive system. We take what councils and industry currently pay to dispose of — organic waste and sewage sludge — and convert it into three high-value outputs:

• Biogas for electricity generation and potential biomethane upgrading
• Bio-fertiliser that returns nutrients to the whenua, displacing synthetic imports
• Treated water returned clean to the environment

This isn't a concept. Our technology has been operating at a commercial facility in Yamunanagar, India since 2021. In New Zealand, we've assembled the building blocks for rapid deployment:

• Contracted revenue with Waste Management Companies, including the country's two largest waste operators.
• A Bell Island demonstration site in Nelson, licensed through NRSBU
• A commercial-scale pipeline  — scaling toward eight plants processing 840 tonnes per day
• An engineering consortium including Beca, Texol Energy, and Kernohan Engineering
• Deep iwi partnerships with Ngāti Toa, Ngāti Whātua Ōrākei, and Ngāti Apa ki te Rā Tō

Every one of our plants sits at the intersection of three revenue streams (waste gate fees, energy sales, and fertiliser offtake) and three national priorities (energy security, emissions reduction, and waste minimisation). That's not a coincidence. It's by design.

Kaitiakitanga as Infrastructure Strategy

Our iwi partnerships are not a social licence checkbox. They are foundational to our model.

Kaitiakitanga — the Māori principle of guardianship and reciprocal stewardship of the natural world — aligns with circular bioeconomy thinking in ways that Western sustainability frameworks often miss. Organic waste is not refuse; it is a resource displaced from its cycle. The whenua receives bio-fertiliser. The awa receives cleaner water. The community receives energy and employment. Nothing is extracted. Everything is returned.

In a country where te Tiriti obligations are woven into our constitutional fabric, energy infrastructure built without indigenous partnership is not just incomplete — it is fragile. Iwi bring generational thinking, deep environmental knowledge, and the community mandate that every successful infrastructure project ultimately depends on.

This is why kaitiakitanga isn't a section in our sustainability report. It's embedded in our constitution.

The Opportunity Is Now

The bioenergy sector is aligned on what's needed. GasNZ's biomethane strategy, the Bioenergy Association's advocacy, and the government's own October 2025 Statement on Biogas all point in the same direction. What's missing is the commitment to accelerate deployment:

• Zero organic waste to landfill by 2040 — unlocking feedstock and cutting an estimated 1,800 kilotonnes of CO₂-equivalent emissions annually
• Full regulatory parity for biomethane — ensuring pipeline services for renewable gas are treated identically to fossil gas under the Energy and Electricity Security Bill
• Directed capital support — the Waste Minimisation Fund and Regional Infrastructure Fund should explicitly target distributed bioenergy infrastructure, not just landfill mitigation
• Iwi co-governance of regional bioenergy development — meaningful partnership in siting, operating, and sharing the benefits

These are not radical proposals. Denmark, the UK, and the EU have all implemented variations of this framework. New Zealand simply needs to commit.

The Question This Decade Will Answer

The government has decided the gas pipes are staying. We agree. That infrastructure is valuable and it should be used.

But the defining energy question for New Zealand this decade is not whether we keep the pipes. It's what we choose to put through them.

One path leads to a billion-dollar import terminal, long-term contracts with international suppliers, and continued exposure to volatile global energy markets.

The other path leads to a distributed network of bioenergy plants across our regions — processing our own organic waste, generating our own renewable gas, returning nutrients to our own soil, and creating skilled jobs in our own communities. Home-grown. Resilient. Circular.

At Alimentary Systems, we're building that second path. We're looking for partners — councils, iwi, investors, and industry leaders — who see what we see: that the future of energy in Aotearoa is already here, waiting in our waste streams.
