© 2025 TeraEarth Limited · Biological Infrastructure
The UK's first biological soil gigafactory. 500,000 sq ft. 100 hectares. Infrastructure for the ground beneath everything.
Living, biologically active soil that builds structure. Not a substitute — an improvement.
Every tonne processed diverts green waste from landfill or low-value disposal.
Healthy soil is the foundation of food security. Building it back at scale is urgent.
Waste in, soil out, food grown, communities fed. The loop closes completely.
Designed for national scale. Integrated with agriculture, councils, and communities. Built to last.
Revenue before processing begins.
Estimated UK topsoil life.
UK annual green waste arisings.
Paid to take it. Paid to sell it.
Four sequential stages — mechanical, thermal, biological, and microbial — producing premium living soil in 60–90 days.
Green waste arrives. We receive payment to accept it.
Mechanical + robotic systems remove all contaminants.
Precision biological system over 60–90 days.
Premium living soil at £100–£300 equiv/tonne.
Green waste contains significant contamination. We solve it before biology begins.
Rotating drum separates organics by size and density.
NIR sensors identify and eject plastics at speed.
Precision extraction of remaining contaminants.
65–75°C sustained heat. Pathogens eliminated.
Inoculation builds soil structure absent from conventional compost.
Diverse communities sustaining long-term biological activity.
Worm systems add the complexity that distinguishes living soil.
Biologically active — fungal networks, microbial communities, biological complexity. A categorically different product.
Negative input cost. Premium output revenue. The economics are structural, not incidental.
Councils pay us to accept green waste. Revenue before a single tonne is processed. As gate fees rise and disposal capacity shrinks, our position improves.
Premium living soil sold via Roots and wholesale channels. High margin on every tonne out. Both streams compound as throughput grows.
From pilot to Terasite, each phase delivers strong returns while building toward significantly improved margins.
Fixed costs spread across 10× the volume. Automation reduces labour per tonne. National contracts provide structural revenue certainty.
Under a single roof. The main processing building alone is larger than five Premier League football pitches laid side by side.
247 acres. Larger than the entire City of London financial district. The windrow fields surrounding the building cover 60 hectares of active biological processing.
The 20-metre-high processing hall is taller than a six-storey building. The far end dissolves into biological haze — you cannot see wall to wall from inside.
180 compost windrow rows surround the building on three sides — each row 120 metres long, steaming from biological heat. From altitude the site looks like it is breathing.
At 200,000+ tonnes per year, the Terasite processes more green waste annually than the entire output of 40 conventional composting operations combined.
A robotic manufacturing system that processes biology. Designed from first principles for full automation.
TeraEarth's material handling draws directly from the two most advanced autonomous logistics systems ever deployed at scale.
750,000+ AMRs globally. Each navigates a shared floor autonomously — zero fixed conveyor infrastructure for horizontal movement. The robots are the infrastructure. TeraEarth applies the same principle: AMRs carry compost instead of shelf units.
Swarm robots on a 3D grid, coordinated by AI processing 4 million decisions per second. THG deployed this at their Omega facility — the world's largest single-floor automated warehouse. Our rail-guided turning system applies the same swarm-coordination logic.
HGVs directed by ANPR cameras and automated gates. NIR sensors scan material composition before tipping. Non-compliant loads rejected automatically. No human required from arrival to tipping.
Trommel screen separates by particle size. NIR cameras identify plastic, glass, and metals at 3m/sec. KUKA robotic arms make final precision extractions. Under 4 minutes per tonne. Human involvement: zero.
Heavy-duty AMRs — each carrying 2–5 tonnes — move feedstock between zones. The fleet repositions windrows, moves material between stages, and delivers to dispatch. 150–300 robots per site. Central AI orchestration in real time.
Robotic turning machines traverse each row on fixed rail guides. A sensor network embedded in every windrow reports temperature, moisture, CO₂, and O₂ every 60 seconds. Turning is condition-triggered — not scheduled. Zero scheduled labour.
Every windrow is a monitored environment. Wireless sensors report every 60 seconds. A central biological AI model makes continuous decisions — when to turn, irrigate, inoculate, harvest. A failing batch is identified in hours, not days.
Finished product delivered by AMR to grading and packaging. Automated bagging lines fill, weigh, seal, and palletise at 60 bags per minute. Outbound logistics integrated with Roots platform data — orders trigger automatic dispatch without a human in the loop.
A conventional operation at 25,000 t/yr employs 40–60 staff. At 200,000 t/yr it needs 300+. Labour scales linearly.
Our system does not. At Terasite scale the per-tonne labour cost approaches zero.
vs 40–60 in a conventional operation of the same throughput.
vs 300+ conventional. 88% lower labour cost per tonne.
From day one, TeraEarth begins accumulating a proprietary dataset that compounds in value with every tonne processed.
Thousands of batches, millions of sensor readings, correlated with output quality. The model learns what conditions produce the best living soil from each feedstock type. This cannot be purchased.
Every batch carries a quality fingerprint — biological activity score, particle size, moisture, microbial diversity index. Over time this becomes the basis for a premium certified tier.
Each additional site adds to the dataset. By year five, the model governing biological processing will be the most sophisticated biological composting AI in existence — trained on more data than any competitor could accumulate in a decade of manual operation.
The current standard was designed for a different era. We are working with government to define what comes next.
PAS 100 is the UK's specification for composted materials. Developed to regulate the composting industry from a waste processing perspective.
It is not a standard for biological soil quality. It measures what compost doesn't contain — not what living soil must contain.
A product can pass PAS 100 and be biologically inert. Our output would exceed any meaningful measure of soil biological activity.
Engaging directly with DEFRA, Natural England, and relevant bodies. Category definition, not lobbying.
A standard measuring microbial diversity, fungal activity, and biological complexity. Output-focused, not waste-focused.
Those who write the rules tend to win the market they create. We intend to be that organisation.
TeraEarth sits at the centre of a closed-loop system — integrated with Roots Allotments and a growing community of urban growers.
Every tonne of green waste enters TeraEarth. It emerges as premium living soil, distributed to Roots Allotments communities. Those communities grow food. Food waste returns to the system.
The loop is structural, not aspirational.
People growing food in Roots communities across the UK.
Than conventional allotment infrastructure.
Infrastructure built to operate across the whole country.
Direct to member — zero intermediary cost.
Infrastructure at this scale requires a specific combination of biological science, engineering, regulatory experience, and commercial relationship. This is that team.
Founded Roots Allotments in 2021, building the UK's largest no-dig allotment community and opening growing spaces for 25,000 people. Operating at national scale, with infrastructure 10x more efficient than conventional allotment models. TeraEarth was built on the insight that the soil supply chain underpinning Roots — and UK agriculture more broadly — needs to be rebuilt from first principles at industrial scale.
The engineer who has physically built automated processing infrastructure at scale. The hire that de-risks the technical narrative for sophisticated investors.
Owns the council pipeline and long-term waste intake contracts. Has sold infrastructure services to local government before.
Owns the compost specification and the biological process that defines output quality. The scientific credibility anchor of the business.
Owns the financial model, manages the raise process, and structures project finance for the pilot facility.
