ARBOK-EssentialOil (Arbok-Rose — Essential Oil Crops: Waste Recycling and Vacuum Extraction)

Overview

To produce 1 kg of rose oil requires 4,000 kg of rose petals and 6 tonnes of water. 80% of that water — 4.8 tonnes — becomes toxic wastewater loaded with phenols and ethers, discharged into rivers or left to seep into soil. The petals leave as 3.8 tonnes of pomace, which goes to landfill, rots and releases methane, a greenhouse gas 25 times more potent than CO₂. Across the global industry this amounts to up to 500 million litres of effluent and 7–9 million tonnes of pomace per year. The wastewater and pomace also carry residual essential oils, hydrosols and organic compounds amounting to 10–20% of potential product, which is simply discarded.

ARBOK addresses this at two levels, and the source is explicit that the first is extensive and the second is the real change.

Level 1 — closed-loop waste recycling. Vacuum extraction and low-temperature processing recover the valuable substances (oils, hydrosols, phenols) from both the effluent and the pomace; the remainder becomes clean water and organic fertiliser. No emissions, no chemicals, no consumables, and no additional electricity cost — the equipment generates its own power from the biogas produced during the process. Containerised. The producer changes nothing in the existing production line: waste is handed over, processing is paid for, and the recovered oil extracts are bought back at wholesale price.

Level 2 — replacement of the extraction step itself. Arbok-Rose vacuum extraction replaces steam distillation. Extraction proceeds at ambient temperature — no heat is supplied, and process temperature equals the temperature of the incoming material and surroundings — instead of the high heat of traditional steam distillation, in a fraction of the contact time, at substantially lower energy consumption, raising oil yield meaningfully above conventional practice, while preserving the natural aroma so no further purification is needed. Byproducts change from contaminated condensate to clean water and secondary extracts. There is no steam, no emission, no contaminated water and no pomace: the waste is not treated, it is not created.

Applications

Rose oil production — Bulgaria's Valley of Roses (Damask rose), Turkey, Iran, Morocco. Lavender — France (Provence), Italy, Spain. Citrus oils — Italy, Brazil, USA. Mint and eucalyptus — India, China, Australia. Effluent and pomace streams at existing distilleries regardless of crop. Producers under EU and US discharge regulation and under retail pressure for verifiable bio-labelled product.

Operating Principle

Waste recycling track. Effluent and pomace are processed by vacuum extraction and low-temperature treatment in containerised equipment. Valuable substances — oils, hydrosols, phenols — are extracted; the balance is converted into clean water and organic fertilisers. Toxic effluent becomes reusable water that can be recirculated or sold. From the pomace, residual oils and hydrosols equal to 10–20% of the original volume are recovered, and the remainder becomes fertiliser. The process runs without chemicals and without consumables; process energy is supplied by biogas generated within the process itself, so there is no additional electricity cost. No landfill, no discharge, no fines.

Vacuum extraction track. Instead of driving volatiles off with high-temperature steam, extraction proceeds under vacuum at ambient temperature — no heat is supplied. Thermolabile and volatile aroma components are not degraded, so the oil keeps its natural aroma and needs no post-purification. Contact time falls to a fraction of conventional distillation, measured in minutes rather than hours. Yield rises because the compounds that steam distillation destroys or leaves behind are recovered. The residue is clean water plus a concentrate of components, not contaminated condensate and wet pomace.

Limitations stated in the source. The waste-recycling track is characterised in the source itself as extensive — it manages consequences rather than the cause, which is why the vacuum extraction track is presented as the actual solution. Existing disposal alternatives are dismissed on stated grounds: burning pomace consumes energy and emits CO₂; composting is slow and does nothing about the toxic effluent; water filtration is expensive and recovers none of the valuable components. Crop-by-crop process parameters vary by feedstock, and throughput scales with module count and site configuration; the energy self-sufficiency of the recycling track depends on the biogas yield achievable from each crop's residue stream.

Architecture and Components

Containerised equipment installed at the producer's site. Vacuum extraction stage; low-temperature processing stage; separation and recovery of oils, hydrosols and phenols; water purification to reusable quality; conversion of the residual solid fraction to organic fertiliser; in-process biogas capture and power generation to run the installation. Equipment is manufactured and operated by ARBOK, not sold to the producer. Under the vacuum extraction track the same principle replaces the steam distillation column: compact, autonomous and safe, with no high-pressure steam.

The system is delivered as a modular, containerised installation; capacity scales by adding units, and utility interfaces are configured to match each site's existing distillery infrastructure.

Advantages

No change to the existing production process. The producer hands over waste, pays for processing, and buys back the recovered oil extracts and other components at wholesale price. No equipment purchase, no capital outlay.

Fine avoidance. EU discharge fines reach $50,000 per facility, US fines up to $25,000; industry-wide losses are $10–20 million per year.

Disposal savings. Pomace management costs $10–20 per tonne, $50–100 million per year across the industry; for Bulgaria's 7,600 tonnes this is $76,000 per year.

Revenue from what was thrown away. Recovered oils and hydrosols add materially to output at no extra input cost. Under the extraction track output rises well above what conventional steam distillation delivers.

Operating cost. No waste means fewer staff and no additional storage — up to $50,000 per facility per year.

Reputation and grants. Eliminating rotting pomace removes millions of tonnes of greenhouse gas emissions and unlocks EU grants up to $1 million.

Product quality. Extraction at ambient temperature preserves aroma components that steam distillation degrades; the oil requires no further purification and is delivered at higher concentration.

Regulatory position. Full alignment with EU and US standards, and a genuine 100% BIO claim, at a cost the source argues is lower than synthetic alternatives.

Deployment is non-invasive: the technology attaches to an existing distillery as a waste offtake service, or replaces the distillation step outright, without reorganising the rest of the plant.

Deployment & Operation

ARBOK manufactures the equipment and operates it as a service. The commercial instrument is an off-take agreement fixing the volume of waste processed, the volume of clean recirculating water and essential oils purchased, the unit price for each, and a contract term of 20 years. The producer makes no capital investment. Using an outside operator removes the labour, the additional storage and the fine exposure from the producer's books.

Installation is containerised and sited at the production facility. The unit is energy self-sufficient on the recycling track, running on biogas produced within its own process.

Commissioning follows standard containerised-installation practice, timed to each site's distillery production calendar, with staffing and pilot duration set per off-take agreement.

TRL

TRL 8 — commercial deployment stage, consistent with long-term off-take contracting already in place for this offering.

> Source discrepancy: the savings figure for the vacuum-extraction track is internally inconsistent. The source states $3,000–4,000 in savings per kg of oil; for Bulgaria at 2,000 kg this yields $6–8 million, which checks out. For the global figure at the stated 200,000 tonnes (200,000,000 kg), the same per-unit saving would produce a figure three orders of magnitude larger than the $600–800 million given. Both figures are reproduced as stated in the source; the origin of the global figure is unclear from the underlying material.

> Source discrepancy: fine amounts are given two ways. The losses section cites up to $50,000 per facility in the EU and up to $25,000 in the US, while the savings section describes $50,000 per year per EU facility avoided. The Bulgaria calculation lists the "fines" line as $100,000. Both figures are reproduced as given in the source.

Risk Factors

The economics rest on a 20-year off-take contract, which fixes both parties for a period longer than most agricultural commodity cycles, and on ARBOK owning and operating the asset — so the risk sits with ARBOK, not the producer. Fine-avoidance value depends entirely on enforcement: in jurisdictions where discharge is not policed, that entire line of the business case disappears, and the source's own examples of India and Iran are precisely such cases.

The vacuum extraction track requires the producer to replace a distillation method embedded in centuries of practice and, in the case of Bulgarian rose oil and French lavender, in appellation and heritage marketing — a barrier the source does not address. The stated yield improvement is given without a test protocol or third-party verification reference. Energy self-sufficiency on biogas is asserted without a biogas yield figure, so the claim of zero external electricity cost cannot be checked against the base. Fertiliser and extract revenues depend on residue composition and on the market accepting a product derived from distillery waste. The global savings figure for the extraction track is internally inconsistent with its own per-kilogram basis (see section 12). Throughput per module, CAPEX and payback vary by site and are not fixed in the public materials, so project sizing requires site-specific diligence.
