dramatically cuts the cost and energy of extracting and processing sapropel — fossilized organic lake/river-bottom sediment rich in microelements and organics, used as an eco-fertilizer to restore degraded soils.
Technology brief
dramatically cuts the cost and energy of extracting and processing sapropel — fossilized organic lake/river-bottom sediment rich in microelements and organics, used as an eco-fertilizer to restore degraded soils.
The challenge
Soil restoration of degraded agricultural land; eco-fertilizer production; valorization of dredged lake/river sediment. Modular, mobile deployment near water bodies.
Users: agriculture, soil-remediation operators, dredging/lake-management programs.
Large-scale lake and reservoir remediation via floating-platform fleets (e.g. the Lake Balaton program): harbors, beaches, shipping approaches, and drinking-water reservoirs losing depth to black silt/sediment buildup.
ARBOK solution
ARBOK-SAPROPEL dramatically cuts the cost and energy of extracting and processing sapropel — fossilized organic lake/river-bottom sediment rich in microelements and organics, used as an eco-fertilizer to restore degraded soils. Traditional freezing or heat-drying methods are energy-intensive and land-hungry; ARBOK's approach cuts energy up to 100× versus heat-drying and land area thousands-fold versus freezing, while preserving sapropel's natural structure and nutrients.
Sapropel slurry is dewatered/concentrated on the Arbok vacuum platform without overheating or freezing the raw material, preserving nutrients and organic structure. Continuous, year-round, modular operation in containers; no skilled operators or heavy power supply required.
Limitations: output depends on raw sapropel concentration; product specs and field agronomic results need validation.
Market and application
Sapropel is an abundant, underused eco-fertilizer; degraded soils and lake/reservoir siltation are global problems. A low-energy, mobile extraction route that preserves nutrients — if validated — opens scalable soil-restoration and organic-fertilizer markets and monetizes dredging.
Value from up-to-100× lower energy vs heat-drying, minimal land/infrastructure, and higher-value preserved product; feedstock often a dredging by-product. No explicit CAPEX/OPEX/price in source — flagged as missing; economics favorable but indicative.
Use cases
Soil restoration of degraded agricultural land; eco-fertilizer production; valorization of dredged lake/river sediment. Modular, mobile deployment near water bodies.
Users: agriculture, soil-remediation operators, dredging/lake-management programs.
Large-scale lake and reservoir remediation via floating-platform fleets (e.g. the Lake Balaton program): harbors, beaches, shipping approaches, and drinking-water reservoirs losing depth to black silt/sediment buildup.
Steps: position container near water body → feed sapropel slurry → vacuum-dewater/concentrate → collect sapropel product. Continuous, minimal staffing. Remaining: product/agronomic validation and scale references.
Fleet deployment (lake/reservoir programs): units mount on floating platforms, ~10 vertically mounted systems per platform, each with its own power system and storage for dry material later shipped ashore to buyers. On-board generation covers the load. 4–6 platforms work a large water body simultaneously, towed by an ordinary tugboat along the work map. Fleet capacity scales linearly with the number of modules and platforms — no new construction; once a project wraps up, platforms relocate to the next water body.
Commercial model: no government CAPEX — ARBOK builds and owns the fleet on private and privately raised capital. Government is asked for two commitments: (1) a payment-guarantee agreement covering work already performed and verified (zones actually cleaned and deepened), and (2) an optional buyback of part of the finished output (pellets, sapropel, fertilizer) at a discount to market price, fixed for a long-term period.
Built on the Arbok vacuum dewatering platform; complements ARBOK-FERTILIZER and soil-restoration programs; pairs with lake/river dredging operations.

Limitations: output depends on raw sapropel concentration; product specs and field agronomic results need validation.
Raw material capacity: up to 200 t/day. Sapropel output: ~6 m³/day (from 3 % concentration). Energy: minimal, can use alternative sources (up to 100× less than heat-drying). Land use: thousands× less than freezing. Form factor: 20–40 ft container, modular/scalable. Staffing: minimal, unskilled. Preservation: retains all natural nutrients and organics.
Note: capacity/energy claims require validation against feedstock variability.
Containerized (20–40 ft) vacuum dewatering/concentration unit; feed intake from dredged sediment; modular, scalable; no special site infrastructure or powerful supply needed; continuous operation.
Technical: preserves nutrients (no overheat/freeze); continuous year-round; mobile/modular; unskilled operation. Economic: up to 100× lower energy than heat-drying, vastly less land than freezing; higher product value from preserved structure. Environmental: valorizes dredged sediment, restores degraded soils, low energy.
