We hold our claims to the same standard as our carbon accounting — independently examined, precisely attributed, on the record.

Climate · beyond carbon

Emissions cut at the source.

Gross emission reductions

Methane captured rather than vented from decomposing organics.

Near-zero waste

Every stream leaves as a product: gas, fertiliser, water, carbon.

Reduced sewage discharge

Water returned cleaner than it arrived.

An end to burn-off

Canterbury burns ~100,000 tonnes of crop residue a year. It's feedstock, not smoke.

Outputs · the loop pays for itself

Four products from one waste stream.

Clean water

On-site energy powers aerobic biological treatment — water returned to the catchment.

Planetary science

Measured against the planet's limits.

We measure every project against the nine planetary boundaries — the science-based limits that define a safe operating space for humanity.

Framework Planetary Boundaries Approach Measured per project Verification Independent, planned

Our system supports positive outcomes across six of the nine planetary boundaries.

The planetary boundaries define nine limits within which humanity can safely operate. We use them as the reference for every BRRP project — mapping where the system can reduce pressure (emissions, fossil-fuel use, soil health, freshwater, land use), and, just as honestly, where it may do less than alternatives. An early scoping session with a planetary-science specialist helped shape this approach; each project's impact will be measured against these boundaries and independently verified.

Te Ao Māori · alignment tested, not assumed

Designed to uphold Mauri.

We work in sustained engagement with iwi across the rohe where our projects sit — from cultural impact through to how nutrients return to whenua. That engagement shapes the system; it isn't a consultation checkbox at the end.

Framework Earth Equity Model Reviewed with A co-designer of the Indigenous Māori view of Doughnut Economics Status Shared with their consent

Designed with Earth, soil and water in mind — upholding Mauri within planetary boundaries.

Our Earth Equity Model frames our role as Tangata Tiriti — guardians distinct from Kaitiaki — supporting the health and wellbeing of earth, sky and water. We reviewed the model directly with a co-designer of the Indigenous Māori view of Doughnut Economics, and share that alignment here with their consent and blessing.

Te Mana o te Wai

The health of water comes first. Our process returns water cleaner than it arrived.

Whenua restored

Nutrients return to the land that produced them, closing the loop for future generations.

Partnership in practice

Engagement with iwi across the rohe where we work, from cultural impact assessment through to operation.

Aligned with

Six goals, measurably.

Our founders belong to the Edmund Hillary Fellowship, whose mission is to incubate solutions to global problems from Aotearoa New Zealand.

Clean Water and Sanitation

Water returned to the catchment, cleaner than it arrived
Wastewater infrastructure funded on circular-economy principles

Climate Action

Methane captured, not vented — gross emission reductions measured to IPCC standards
Zero waste to landfill

Industry, Innovation and Infrastructure

Every form of bio-organic waste in a single plant — reducing the burden on farmers, horticulture and ratepayers
Gross emission reductions capitalised to fund clean-energy infrastructure

UN Sustainable Development Goal 11: Sustainable Cities and Communities

Sustainable Cities & Communities

Scale suited to small towns, creating regional green jobs
A smaller land footprint to process waste

Affordable and Clean Energy

400% higher biogas yield than conventional single-stage AD
Energy resiliency

UN Sustainable Development Goal 3: Good Health and Wellbeing

Good Health & Wellbeing

Less sludge discharged to land and ocean, reducing ocean acidification
Fewer nitrates entering Aotearoa's groundwater

"I am excited about the potential of Alimentary's technology to revolutionise the way New Zealand deals with its biosolids."

Writing as one of Aotearoa's most decorated wastewater engineers — over 65 published technical papers and board roles spanning the Water Environment Federation, Engineering NZ and Water NZ — he endorsed our understanding of the sector's challenges and recommended the founders' expertise from direct first-hand observation.

Endorser Deborah Crowe Standing Former Commercialisation Development Manager, KiwiNet · Edmund Hillary Fellow

Alimentary is "leading the sort of innovation required to establish a sustainable bioeconomy."

Her endorsement, grounded in a career commercialising New Zealand research, including co-founding circular-economy venture Usedfully, draws on shared experience as an Edmund Hillary Fellow and first-hand knowledge of the founders' intellect, business acumen and drive.
