Key takeaways
- Arovela's geothermal-dried fruit registers 0.02-0.05 kg CO₂e per kilogram of finished product — a 93-97% reduction against conventional fossil-fuel drying and a 95-97% reduction against electricity-intensive freeze-drying, making it the closest the dried fruit industry has come to carbon-neutral processing at commercial scale.
- Carbon neutral dried fruit geothermal processing is not a marketing aspiration; it is a measurable engineering outcome. Subsurface thermal energy drawn from wells in Sindirgi, Balikesir eliminates combustion entirely from the drying step, removing the single largest emission source in any dried fruit product's life cycle.
- For B2B buyers reporting under EU CSRD, CDP Climate, or SBTi FLAG, switching to a geothermal-dried supplier delivers an auditable, supplier-specific emission factor that survives third-party assurance — no offsets, no avoided-emission claims, no creative accounting.
- The residual carbon in Arovela's product comes from transport, packaging, and agricultural inputs — not from processing energy. This distinction matters for honest sustainability communication and for mapping reduction pathways across the full value chain.
- Commercial co-benefits extend beyond carbon: stable year-round production unaffected by weather or energy markets, superior nutrient retention at low drying temperatures, and a brand narrative that resonates with retailers mandating supplier sustainability scorecards.
Introduction
The global food industry produces approximately 13.7 billion metric tons of CO₂-equivalent emissions annually — roughly one-third of all anthropogenic greenhouse gases. Within that landscape, post-harvest processing is the silent heavyweight. It does not photograph well. It does not make headlines. But it accounts for more embedded carbon in a packet of dried fruit than the farming, the shipping, and the retail refrigeration combined.
Arovela has built its entire production model around eliminating that carbon. Not reducing it by 10%. Not offsetting it with credits purchased from a broker in another hemisphere. Eliminating it — by replacing fossil fuel combustion with geothermal heat drawn directly from the earth beneath the facility.
Carbon neutral dried fruit geothermal processing is the convergence of geology, engineering, and a deliberate commercial choice. When a company sits on top of one of the most productive geothermal fields in western Turkey and chooses to pipe that heat into food-grade drying chambers instead of burning natural gas, the carbon arithmetic changes fundamentally. The drying step — which in a conventional facility generates 55-70% of a dried product's total cradle-to-gate emissions — drops to near zero.
This article is a full accounting of what that means. The data. The methodology. The boundaries of the claim. The residual emissions that remain. And the commercial, regulatory, and brand implications for B2B buyers evaluating sustainable dried fruit production for their Scope 3 inventories.
The carbon problem in conventional dried fruit production
Dried fruit is an ancient product category with a modern emissions problem. The global market, valued at over USD 10 billion and growing at 5-6% annually, depends overwhelmingly on thermal energy to convert fresh produce into shelf-stable ingredients. And that thermal energy, in the vast majority of production facilities worldwide, comes from burning hydrocarbons.
Energy consumption in thermal drying
Removing water from fruit is energy-intensive by nature. Fresh fruit enters the dryer at 75-85% moisture content. The finished product exits at 12-18%. That means every kilogram of dried fruit requires the evaporation of roughly 3-5 kilograms of water, depending on the commodity. The latent heat of evaporation — 2,260 kJ per kilogram of water at atmospheric pressure — sets a thermodynamic floor that no engineering innovation can bypass.
In practice, real-world energy consumption sits well above that theoretical minimum. Conventional tunnel and tray dryers operate at 35-55% thermal efficiency, meaning that nearly half the heat generated is lost to exhaust, radiation, and poor insulation. A typical natural gas-fired drying facility consumes 2.0-3.5 kWh of thermal energy per kilogram of dried product. At scale — a facility processing 5,000 metric tons of dried fruit annually — that translates to 10,000-17,500 MWh of thermal energy demand, the equivalent of heating roughly 500-700 European households for a year.
Fossil fuel dependency in food processing
The drying industry's dependence on fossil fuels is structural, not incidental. Natural gas infrastructure is established, reliable, and priced into every cost model. LPG serves facilities without pipeline access. In some regions, coal and fuel oil remain in use despite mounting regulatory pressure. The result is an industry where the processing step alone generates 850-1,200 kg CO₂e per metric ton of conventionally dried fruit — before the product has been packed, shipped, or shelved.
This is not a marginal contribution. In a full life-cycle assessment of dried apricots delivered to a European warehouse, the drying step typically represents 58-68% of total cradle-to-gate emissions. Farm operations contribute 7-10%. Inland transport adds 2-3%. Ocean freight accounts for 8-12%. The dryer is where the carbon concentrates, and it is where the intervention must happen.
Scope 3 emissions in global supply chains
For the B2B buyer, these processing emissions land squarely in Scope 3 Category 1 — Purchased Goods and Services — which the GHG Protocol Corporate Value Chain Standard defines as all upstream emissions associated with the production of goods purchased by the reporting company. Category 1 is almost always the largest Scope 3 bucket for food companies, typically accounting for 60-80% of total corporate emissions.
The uncomfortable reality for procurement teams is that Scope 3 Category 1 is also the hardest to measure and the hardest to reduce through internal action alone. You cannot redesign your supplier's factory from your head office. What you can do is choose suppliers whose processing methods generate fundamentally less carbon. That is not a marginal procurement decision — it is a strategic emission-reduction lever that can move the needle more than any internal efficiency programme.
For a detailed walkthrough of Scope 3 accounting methodology as it applies to dried ingredients, see the Scope 3 carbon reduction guide.
Geothermal energy — nature's carbon-free heat source
Geothermal energy is thermal energy stored in the earth's crust. Unlike solar and wind, it is not intermittent. Unlike biomass, it does not require combustion. Unlike nuclear, it does not require fuel rods or cooling towers. It is simply heat — continuously available, renewably replenished by radioactive decay and residual planetary formation energy — waiting to be extracted.
How geothermal wells work for food processing
The principle is straightforward. Wells drilled to depths of 200-2,000 metres tap reservoirs of hot water or steam at temperatures ranging from 40 °C to over 200 °C. For food-processing applications, the sweet spot is 65-110 °C at the wellhead — temperatures ideal for enclosed drying chambers that operate at 40-65 °C drying-air temperature after heat exchange.
The hot water is pumped to the surface, passed through plate or shell-and-tube heat exchangers that transfer thermal energy to clean drying air, and then returned to the subsurface reservoir through re-injection wells. The closed-loop design means no water is consumed and no combustion products are generated. The only electricity required is for circulation pumps and ventilation fans — typically 0.05-0.15 kWh per kilogram of dried product, compared with 2.0-3.5 kWh of thermal input in a fossil-fuel system.
The emission factor for the entire geothermal drying operation — including pumping electricity drawn from the Turkish national grid — runs 2-6 kg CO₂e per GJ of delivered heat. For comparison: natural gas generates 56-62 kg CO₂e per GJ, LPG generates 66-72, fuel oil generates 74-78, and coal generates 94-100. This is not an incremental improvement. It is a reduction of one to one-and-a-half orders of magnitude.
Sindirgi, Balikesir — Arovela's facility
Arovela's geothermal drying operations are located in the Sindirgi district of Balikesir province, in western Turkey's Aegean geothermal belt. This region sits on one of the most geothermally active zones in Europe, with wellhead temperatures of 80-110 °C and reservoir capacities that have supported continuous extraction for decades without measurable temperature decline.
The facility draws geothermal heat from licensed wells and channels it through food-grade heat exchangers into enclosed, HACCP-certified drying chambers. Because the heat is free at the wellhead and available 24 hours a day, 365 days a year, there is no operator incentive to push drying temperatures above optimal levels to save fuel — a critical distinction from fossil-fuel facilities where time pressure and energy cost drive temperatures above 70 °C, degrading nutrients and colour. For the science behind this preservation advantage, see the vitamin C preservation research.
The result is a production model where the drying step — the single largest emission source in conventional dried fruit manufacturing — contributes near-zero carbon to the finished product. The facility's remaining energy consumption (lighting, sorting lines, packaging equipment) draws from the national grid, and those emissions are accounted for separately in the full carbon audit.
Energy economics: geothermal vs fossil fuel
Beyond emissions, the economic structure of geothermal energy provides stability that fossil fuels cannot match. Natural gas and LPG prices are subject to global commodity volatility, geopolitical disruption, and carbon pricing mechanisms. Geothermal heat, once the well infrastructure is in place, has near-zero marginal fuel cost. Operational expenses are limited to pump maintenance, heat-exchanger servicing, and electricity for ancillary systems.
This cost stability translates directly into FOB price stability for B2B buyers. When your supplier's largest energy input is not indexed to a volatile commodity, your contract pricing becomes more predictable — a practical advantage that procurement teams value independently of the sustainability narrative.
For a broader comparison of drying technologies, costs, and buyer considerations, see the geothermal drying B2B guide.
Carbon footprint comparison
The following table compiles life-cycle assessment data normalised to one kilogram of dried fruit product (starting from fresh fruit at approximately 80% moisture content, dried to 12-18% final moisture). All figures reflect cradle-to-gate boundaries — from raw material intake at the drying facility through to packed, palletised product ready for shipment. Farm-gate emissions, transport, and end-of-life are excluded as they are common across all methods.
| Drying method | Energy source | kg CO₂e per kg dried product | Annual availability | Key limitation | | --- | --- | --- | --- | --- | | Geothermal (Arovela) | Subsurface thermal | 0.02-0.05 | 24/7/365 | Geographically constrained | | Conventional hot-air | Natural gas / LPG | 0.30-0.50 | Year-round | High emissions, nutrient loss | | Freeze-dried | Grid electricity | 0.80-1.20 | Year-round | Very high cost, energy-intensive | | Solar (open-air) | Solar radiation | 0.01-0.03 | Seasonal only | Food safety risk, inconsistent | | Solar-hybrid | Solar + electric backup | 0.15-0.35 | Partially seasonal | Requires backup, variable output |
Geothermal dried fruit: 0.02-0.05 kg CO₂e per kg
Arovela's geothermal drying process generates 0.02-0.05 kg CO₂e per kilogram of finished dried fruit. This figure includes the electricity consumed by circulation pumps, ventilation fans, and monitoring systems, calculated using the Turkish national grid emission factor. The heat itself — the dominant energy input — is renewable and generates no combustion emissions.
At facility scale, this translates to approximately 35-90 kg CO₂e per metric ton of dried product. For a standard 20-foot container holding approximately 18 metric tons of dried fruit, the total processing-related emissions are 630-1,620 kg CO₂e — compared with 15,300-21,600 kg CO₂e for the same container dried conventionally. The reduction is 90-97%.
Conventional hot-air: 0.30-0.50 kg CO₂e per kg
Conventional tunnel and tray dryers fired by natural gas or LPG generate 0.30-0.50 kg CO₂e per kilogram of dried product at the process level. This range reflects the variation in thermal efficiency (35-55%), fuel type, and facility age. Newer facilities with heat-recovery systems sit at the lower end; older facilities burning LPG or fuel oil sit higher.
These figures align with published LCA data from Turkish, Iranian, and Chinese drying operations — the three largest global producers of dried fruit. Incremental efficiency improvements can shave 10-20% from this range, but the combustion chemistry of fossil fuels sets a structural floor that no operational optimisation can break through.
Freeze-dried: 0.80-1.20 kg CO₂e per kg
Freeze-drying (lyophilisation) consumes 4.0-7.0 kWh of grid electricity per kilogram of water removed. On the EU average grid mix (approximately 0.25 kg CO₂e per kWh), this translates to 0.80-1.20 kg CO₂e per kilogram of finished product. On coal-heavy grids, the figure climbs higher. Despite its superior texture and rehydration properties, freeze-drying carries a carbon burden that exceeds even conventional hot-air drying in many grid contexts. For a detailed comparison, see the freeze-dried vs geothermal comparison.
Sun-dried: variable, weather-dependent
Open-air solar drying produces the lowest direct emissions (0.01-0.03 kg CO₂e per kg) but cannot serve as a reliable commercial method for export-quality product. Weather dependency, dust and insect contamination, inconsistent moisture control, and inability to meet EU food safety standards for water activity and microbial limits make it unsuitable for serious B2B supply chains. It remains common in subsistence and local-market contexts.
LCA methodology and boundaries
All emission factors cited in this article use cradle-to-gate system boundaries conforming to ISO 14040/14044 (Life Cycle Assessment) and ISO 14067 (Carbon Footprint of Products). The functional unit is one kilogram of packed, palletised dried fruit at the factory gate. Included processes: raw material reception, washing, pre-treatment (where applicable), drying, sorting, grading, packaging, and palletisation. Excluded: upstream agricultural emissions, outbound transport, retail storage, consumer use, and end-of-life. Emission factors for grid electricity follow the location-based method using national grid averages. Emission factors for fossil fuels use IPCC 2006 guidelines (updated 2019) well-to-combustion values.
This boundary definition is consistent with how Scope 3 Category 1 emission factors are calculated under the GHG Protocol — meaning the figures can be used directly in a buyer's corporate carbon inventory without methodological adjustment.
What "near-carbon-neutral" means — and what it doesn't
Intellectual honesty is essential in sustainability communication. Arovela uses the term "near-carbon-neutral" rather than "carbon-neutral" because the distinction matters — for regulatory compliance, for brand credibility, and for the accuracy of any ESG report that references our products. Here is where the emissions are, where they are not, and what the honest accounting looks like.
Processing emissions vs full supply chain
The geothermal drying step itself generates near-zero carbon emissions. This is a verifiable, auditable fact supported by energy metering data and third-party carbon assessments. When we say the processing is near-carbon-neutral, we mean the drying operation specifically — the step that conventionally generates 55-70% of a dried fruit product's total emissions.
However, a dried apricot does not materialise at the factory gate. It is grown on a farm, transported to the facility, processed, packed into materials that were manufactured elsewhere, and shipped across oceans to a buyer's warehouse. Each of those steps carries a carbon cost that sits outside the drying operation.
Transport, packaging, and agricultural inputs
A representative full supply chain emission breakdown for one metric ton of Arovela geothermal-dried fruit delivered to an EU warehouse:
| Supply chain stage | kg CO₂e per ton | Share of total | | --- | --- | --- | | Farm operations (cultivation, irrigation, harvest) | 80-150 | 22-32% | | Post-harvest drying (geothermal) | 20-50 | 5-11% | | Sorting, grading, packing | 40-80 | 11-17% | | Packaging materials (production) | 30-60 | 8-13% | | Inland transport (Turkey) | 20-45 | 5-10% | | Ocean freight (Turkey to EU) | 60-120 | 16-26% | | EU inland logistics | 25-55 | 7-12% |
Total: approximately 275-560 kg CO₂e per metric ton. Compare this with 1,200-1,800 kg CO₂e for the same product dried conventionally. The geothermal advantage compresses the total footprint by 55-77%, with the drying step contributing only 5-11% of the remaining total instead of the conventional 58-68%.
Honest accounting: where residual emissions come from
The residual emissions in Arovela's supply chain come from three sources:
Agricultural inputs. Fertiliser production and application, irrigation pumping, tractor fuel, and soil emissions from cultivation contribute 80-150 kg CO₂e per metric ton. These are largely outside the processor's direct control but can be influenced through contract farming agreements that specify low-input practices.
Transport. Moving raw material from orchards to the facility, and finished product from Turkey to destination markets, generates emissions proportional to distance and mode. Ocean freight from Izmir to Rotterdam adds approximately 15-25 kg CO₂e per metric ton — a fraction of the processing emissions saved.
Packaging. Corrugated cardboard, polyethylene liners, and palletisation materials carry embodied emissions from their own manufacturing processes. Arovela is progressively shifting to recycled-content and mono-material packaging to reduce this line item.
Path to true carbon neutrality
The pathway from near-carbon-neutral to fully carbon-neutral processing runs through four interventions, prioritised by impact and feasibility:
- On-site solar PV for grid-electricity offset (sorting lines, lighting, packaging equipment) — currently in evaluation.
- Electric vehicle fleet for inland transport between orchards and facility.
- Regenerative agriculture partnerships with contracted growers to reduce farm-gate emissions.
- Certified carbon removal credits for residual emissions that cannot be eliminated through operational changes — used as a last resort, not a first strategy.
This sequencing reflects a principle: reduce first, remove only what you cannot reduce. It is the approach that the Science Based Targets initiative (SBTi) endorses, and it is the approach that withstands scrutiny from auditors, regulators, and informed buyers.
ESG reporting frameworks and how geothermal fits
The regulatory landscape for sustainability disclosure is converging rapidly. Four frameworks now dominate the ESG reporting requirements that B2B food buyers must navigate. Each one treats Scope 3 processing emissions differently, but all four reward supplier-specific data over industry averages — and all four recognise renewable energy at the processing step as a legitimate emission reduction.
GHG Protocol Scope 3 (Category 1: Purchased Goods)
The GHG Protocol's Scope 3 Standard defines three data-quality tiers for Category 1 emission factors:
- Tier 1 (supplier-specific): Actual energy data from the supplier's facility, ideally verified by a third party. This is the highest-quality input and the one that CSRD auditors and CDP scorers prefer.
- Tier 2 (product-level): Published product carbon footprints from industry databases (e.g., Ecoinvent, DEFRA conversion factors).
- Tier 3 (spend-based): Emission factors applied per dollar of procurement spend — the crudest method, used when no better data is available.
Arovela provides Tier 1 supplier-specific emission factors for its geothermal-dried products, derived from annual energy audits, metered electricity consumption, and wellhead thermal output data. This data can be plugged directly into a buyer's Scope 3 inventory at the highest data-quality tier, improving both the accuracy and the assurance-readiness of the corporate carbon report.
EU CSRD (Corporate Sustainability Reporting Directive)
The CSRD, effective for large companies from financial year 2025 and cascading to listed SMEs from 2026, requires reporting under the European Sustainability Reporting Standards (ESRS). ESRS E1 (Climate Change) mandates Scope 3 disclosure including Category 1, with explicit requirements for:
- Calculation methodology documentation
- Data-quality grading (supplier-specific vs estimated)
- Transition plan milestones tied to real emission reductions
Switching to a geothermal-dried supplier qualifies as a documented transition plan action — auditable, permanent, and not subject to reversal risk. For a broader view of CSRD and related EU regulations, see the EU Green Deal supplier guide.
CDP Climate disclosure
CDP's annual climate questionnaire, completed by over 23,000 companies globally, scores respondents on the granularity and ambition of their Scope 3 disclosure. High scores require:
- Category-level Scope 3 breakdowns with supplier-specific data
- Identified emission hotspots with documented reduction actions
- Quantified year-on-year emission reductions attributable to specific interventions
A documented switch from conventionally dried to geothermal-dried ingredients — with before-and-after emission factors — is precisely the type of intervention that moves a CDP score from B to A-list territory.
Science Based Targets initiative (SBTi)
Companies setting science-based targets under the SBTi framework must include Scope 3 emissions if they represent more than 40% of total emissions (which they almost always do in food companies). The SBTi FLAG (Forest, Land, and Agriculture) guidance further requires:
- Near-term Scope 3 reduction targets aligned with 1.5 °C pathways
- Demonstrated real emission reductions (not offsets)
- Supplier engagement as a documented reduction strategy
Geothermal processing directly addresses the FLAG pathway's emphasis on real, permanent reductions in the agricultural supply chain.
ESG framework requirements and geothermal data points
| Framework | Scope 3 requirement | Data quality preference | How geothermal fits | | --- | --- | --- | --- | | GHG Protocol | Category 1 disclosure mandatory for comprehensive reporting | Tier 1 supplier-specific preferred | Metered energy data, annual carbon audit | | EU CSRD (ESRS E1) | Scope 3 disclosure with methodology and data quality grading | Supplier-specific over estimated | Auditable facility-level emission factor | | CDP Climate | Category-level breakdown, hotspot identification, reduction actions | Supplier-specific data scores higher | Documented intervention with quantified reduction | | SBTi FLAG | Near-term Scope 3 target, real reductions, supplier engagement | Measured reductions over offset claims | Permanent processing-energy switch, no reversal risk | | TCFD / ISSB (IFRS S2) | Climate risk and opportunity disclosure including value chain | Scenario analysis with supplier data | Supply chain resilience (no fossil fuel price exposure) |
This convergence means that B2B buyers using geothermal-dried ingredients can address multiple reporting frameworks with a single supplier-specific data set. One emission factor, properly documented, serves GHG Protocol, CSRD, CDP, and SBTi simultaneously.
Commercial advantages for B2B buyers
Sustainability credentials are increasingly a commercial input, not just a compliance output. For B2B buyers sourcing dried fruit, the decision to switch to a geothermal-dried supplier delivers measurable advantages across four dimensions.
Retailer sustainability requirements
Major European and North American retailers are imposing supplier sustainability scorecards that directly affect listing decisions, shelf placement, and promotional support. Tesco's Sustainable Supplier Assessment, Lidl's CSR performance matrix, Carrefour's Food Transition Index, and Whole Foods Market's Sourcing Values all include embedded-carbon metrics for ingredients.
A supplier that can document a 90-97% reduction in processing emissions gives its B2B customer a data point that moves the scorecard needle. For private-label brands — where the retailer is the brand owner and bears direct responsibility for supply chain disclosures — this is especially powerful.
Consumer willingness to pay for sustainability
Multiple studies confirm that consumer segments in the EU, UK, US, and Japan demonstrate measurable willingness to pay premiums of 10-25% for products with verifiable sustainability credentials. The critical word is "verifiable." Vague claims of environmental friendliness are losing traction; specific, quantified claims backed by third-party data are gaining it.
A dried fruit product that can state its processing carbon footprint — 0.02-0.05 kg CO₂e per kg, verified by independent audit — provides the kind of specific claim that resonates with informed consumers and passes regulatory scrutiny under EU Green Claims Directive requirements.
Tender and RFP scoring advantages
In B2B procurement, sustainability criteria are migrating from "nice to have" appendices to weighted scoring sections in formal tenders. A 2025 survey by EcoVadis found that 78% of procurement professionals now include ESG criteria in supplier evaluations, with carbon footprint data as the most commonly requested metric.
When an RFP allocates 15-25% of the total score to sustainability (as is increasingly common in EU public procurement and large retail tenders), the supplier with auditable, near-zero processing emissions holds a structural scoring advantage that competitors using fossil-fuel drying cannot match through incremental improvements.
Brand narrative and marketing material
For brand owners developing consumer-facing sustainability narratives, the geothermal story is unusually compelling. It is concrete (heat from the earth, not from a gas burner), visual (the facility, the wells, the landscape), and scientifically verifiable (metered energy data, published emission factors). It does not rely on complex offset mechanisms that consumers struggle to understand or trust.
Arovela provides B2B customers with sourcing documentation, facility photography, and emission-factor data that can be incorporated directly into brand sustainability reports, pack copy, and marketing materials — subject to the buyer's own legal review of claims.
Case in point: Arovela's sustainability credentials
Arovela's commitment to sustainable dried fruit production is not a recent pivot; it is the founding logic of the operation. Building a food-processing facility on a geothermal field was a deliberate infrastructure decision, not a retrofit.
Certifications and third-party verification
Arovela holds and maintains certifications that validate both food safety and environmental management. These include ISO 22000 (Food Safety Management Systems), HACCP, and quality management certifications. The full certifications portfolio is available on our website.
Critically, certifications are not the same as carbon data. A certificate confirms that a management system exists; an emission factor confirms what the facility actually emits. Arovela provides both: the management system certifications that procurement teams require for supplier qualification, and the specific emission factors that ESG teams require for Scope 3 reporting.
Annual carbon audit data
Arovela conducts annual energy audits that document total electricity consumption from the national grid, geothermal heat utilisation, and the resulting product-level emission factors. These audits follow ISO 14064 (Greenhouse Gas Inventories) and ISO 14067 (Carbon Footprint of Products) methodologies.
The key figures from the most recent audit period:
- Geothermal heat utilisation: 95-97% of total thermal energy for drying
- Grid electricity consumption: limited to pumps, fans, sorting lines, lighting, and packaging equipment
- Product-level emission factor (drying step): 0.02-0.05 kg CO₂e per kg dried product
- Full facility emission intensity: monitored and reported annually with year-on-year trend data
These figures are available to qualified B2B buyers as part of the pre-contractual due diligence package. For buyers conducting CSRD-mandated supplier assessments, this data slots directly into the Scope 3 Category 1 calculation.
Renewable energy certificates
The geothermal energy used in Arovela's drying operations qualifies as renewable under both Turkish energy legislation and EU Renewable Energy Directive (RED III) classification. The thermal energy is drawn from licensed geothermal wells and does not require combustion, nuclear fission, or fossil-fuel inputs.
For B2B buyers claiming renewable energy content in their supply chains, this classification provides the regulatory foundation for the claim. Unlike renewable electricity certificates (which can involve complex market-based accounting), geothermal thermal energy is physically consumed on-site — there is no unbundling, no trading, and no double-counting risk.
For a deeper exploration of how these credentials map to ESG audit requirements, see the sustainable agriculture and ESG guide.
Frequently asked questions
Is geothermal-dried fruit truly carbon-neutral?
The drying process itself is near-carbon-neutral, generating only 0.02-0.05 kg CO₂e per kilogram of dried product — almost entirely from grid electricity for pumps and fans, not from the heat source. However, the full product life cycle includes agricultural inputs, transport, and packaging, which contribute additional emissions. Arovela uses "near-carbon-neutral" to describe the processing step accurately, and provides full supply chain emission data for buyers who need cradle-to-gate or cradle-to-grave figures for their Scope 3 reporting.
How does geothermal drying compare to purchasing carbon offsets?
They are fundamentally different. Geothermal drying is a physical emission avoidance — the carbon is never generated in the first place because no fossil fuel is burned. Carbon offsets are financial instruments that fund emission reductions or removals elsewhere to compensate for emissions that did occur. The SBTi and EU CSRD both prioritise real emission reductions over offset mechanisms. For buyers building credible decarbonisation pathways, supplier-level emission avoidance through geothermal processing is a higher-quality intervention than purchasing offsets to cover a fossil-fuel supplier's emissions.
Can I use Arovela's emission data in my corporate Scope 3 report?
Yes. Arovela provides supplier-specific emission factors calculated under ISO 14067 methodology, suitable for Tier 1 (supplier-specific) reporting under the GHG Protocol Scope 3 Standard. This data can be used directly in your Category 1 (Purchased Goods and Services) inventory and is designed to withstand CSRD third-party assurance and CDP verification processes. Emission factors are updated annually following the facility energy audit.
Does geothermal drying affect the taste or quality of the product?
Geothermal drying operates at 40-65 °C — significantly lower than conventional hot-air drying at 70-90 °C. This lower temperature range preserves 70-85% of vitamin C, retains natural colour and aroma compounds, and eliminates the case-hardening and Maillard browning that plague high-temperature processes. Sensory panel evaluations consistently score geothermal-dried fruit higher on colour, aroma, and texture than conventionally dried equivalents from the same harvest lot. See the vitamin C preservation science article for the detailed research data.
What is the minimum order quantity for geothermal-dried fruit?
Commercial conversations begin at one 20-foot container (approximately 18 metric tons). Sample quantities of 1-5 kg with full Certificate of Analysis and carbon footprint documentation are available for qualification purposes. For private-label retail packaging, MOQ per SKU starts at 5,000-10,000 units depending on format. Visit the geothermal-dried fruit product range for the full category listing.
Partner with a sustainable supplier
The transition to low-carbon supply chains is no longer optional for food brands operating in regulated markets. EU CSRD, CDP Climate, SBTi FLAG, and retailer sustainability scorecards are converging to make supplier-level emission data a procurement requirement — not a sustainability team aspiration.
Arovela's geothermal-dried fruit delivers 93-97% lower processing emissions than conventional alternatives, backed by auditable energy data, ISO-aligned carbon accounting, and annual third-party verification. For B2B buyers who need real emission reductions — not offsets, not estimates, not aspirational targets — this is the most impactful single sourcing decision available in the dried fruit category.
