ARBOK Peat (Arbok Vacuum Drying for Peat → Fuel Briquettes)

Overview

ARBOK Peat applies the Arbok deep-vacuum platform to wet peat to replace classical thermal and field drying with ambient-temperature vacuum dehydration. Raw peat (85–95% water) enters a sealed chamber held under deep vacuum, where water boils at the temperature of the incoming stream — down to sub-zero ambient conditions — without any added heat. Vapor is condensed into clean water; what stays is dry peat concentrate at 10–15% moisture, ready for briquette pressing. Energy demand is 2–3 kWh per ton of throughput, against 600–1,200 kWh/t water for classical thermal drying. The system removes the two structural problems of the peat industry — oxidation losses on field drying (30–40% of mass) and fire/dust hazard plus 30–40% energy overhead on thermal drying — and adds a clean-water by-product and an optional humic/wax/bitumen side stream.

Applications

Primary use cases:

• Conversion of wet peat into fuel briquettes (calorific value 18–22 MJ/kg, lignite-class)

• Modernization of existing peat enterprises (Russia, Belarus, Finland, Estonia, Ireland)

• Localized solid-fuel supply for off-grid northern regions and rural heating

• Briquette substitute for coal and firewood in low-sulfur applications

• Biorefinery: humic acids, fulvates, waxes/bitumens as standalone product streams (subject to peat-specific yield validation)

Typical scenarios:

• On-site processing at peat extraction fields

• Container-mounted modules deployed to remote bogs without thermal infrastructure

• Retrofit of plants with thermal dryers eliminating fire/insurance burden

Industries and users:

• Peat extraction enterprises

• District heating utilities in northern regions

• Agrochemistry producers (humic-fertilizer line)

• Greenhouse and rural heating operators

• Government energy-security and rural electrification programs

Scale:

• Single module: up to 200 t/day raw peat (~70,000 t/year)

• Cluster: 5–10 modules (50,000–100,000 t/year output)

• Programme scale: 90–110 modules covers 25% of world peat extraction

Operating Principle

The system operates under deep vacuum. At this pressure water transitions to vapor at the temperature of the incoming stream, with no external heat input and no oxygen in the chamber. Wet peat is fed in, vapor leaves, dry concentrate stays.

Key steps:

1. Hydraulic or mechanical feed of wet peat (85–95% moisture)
2. Sealed vacuum chamber under deep vacuum
3. Phase change: water vaporizes at ambient temperature (down to sub-zero conditions in cold climates)
4. Vapor condensation → clean water output
5. Dry peat concentrate at 10–15% moisture → briquette press
6. Optional: fractional condensation captures humic/wax/bituminous fractions as standalone by-products

Limitations:

• Requires stable vacuum conditions

• In sub-zero ambient operation a basic shed is recommended (no heat for the process itself)

• Peat-specific feed handling parameters to be finalized at pilot stage

• Yields of humic/wax fractions for raw peat to be validated experimentally

• Module delivery and tie-in to feed and briquette press

• Commissioning with staged loading

Operating conditions:

• Outdoor pad in mild climates; basic shed in sub-zero regions

TRL

TRL 5–6 (peat-specific) — to be reviewed and confirmed by ARBOK

Evidence basis:

• Arbok-VC and AZOW platforms (TRL 8–9) operate on the same physical principles — deep vacuum, ambient temperature, water-from-organic-matrix separation — and are commercially deployed for produced water, sewage, biogas digestate, and pyrolysis liquid

• AZOW briquettes from organic concentrate already certified at 14–20 MJ/kg, comparable to lignite

• Peat-specific extension is a feedstock adaptation, not a new physical principle

Remaining steps:

• Pilot run on real peat (highmoor and lowmoor)

• Validation of feedstock-handling and energy intensity for peat

• Confirmation of humic / wax / bitumen yields as separable products

• Patent filing on the integrated peat-vacuum-biorefinery configuration

Market Potential

Addressable markets:

• Russian peat reserves (175 bln t) — largest untapped solid-fuel resource

• Belarus, Finland, Ireland, Estonia, Sweden — established peat consumers

• Indonesia (tropical peat) — climate-sensitive but very large resource

• Northern district heating systems off the gas grid

Material valuation:

• 400+ bln t world reserves → ~48 bln t dry briquette equivalent

• At $80/t average market price → ~$3.8 trillion of in-ground material value

• Energy equivalent: ~960 EJ (1.5× current annual world primary energy consumption)

Programme scenario (25% of current world output, 6.25–7.5 mln t/year raw):

• Output: 710–855 thousand t/year briquettes

• Total annual revenue (briquettes + water + carbon + by-product fractions): €155–215 mln/year

• Total Capex: €180–220 mln

• Programme payback: ~5 years

Typical Project Economics

Single module:

• Throughput: 200 t/day raw → 7,500–8,000 t/year briquettes

• Capex: ~€2 mln

• Service life: 20 years

• OPEX (Europe): energy €58k/year + raw + labour + maintenance ≈ €700–800k/year

• Revenue at €150/t briquette + water: ~€1.14 mln/year

• EBITDA: €330–430k/year

• Payback: 5–6 years

• Post-payback cumulative cash flow: €4.5–6 mln per module

Programme (90–110 modules):

• Capex: €180–220 mln

• Annual revenue (full basket): €155–215 mln

• Carbon credit upside: $8–16 mln/year

• Humic/wax fractions upside: +€30–60 mln/year (subject to pilot validation)

• Frees ~4–6 mln tons of coal-equivalent fuel/year currently lost to drying

Risk Factors

• Peat-specific pilot data not yet generated — TRL gap from adjacent platforms must be closed

• Peat regulatory pressure in EU (peat not classified as renewable) — mitigated by domestic markets in Russia/CIS and by climate-positive operating model

• Briquette market price volatility (€100–250/t spread)

• Feed-handling characteristics differ from sewage / pyrolysis liquid — module mechanical configuration to be finalized at pilot

• Humic / wax / bitumen yields for raw peat to be experimentally confirmed before commercial sale of by-product

• Reputational risk of "coal 2.0" framing — to be addressed by low-sulfur, low-emission, bog-rehabilitation positioning

• Insurance and certification timelines for new deployments
