Managing Emissions in Dutch Fish Meal and Fish Oil Operations
Fish meal and fish oil production in the Netherlands draws on centuries of seafaring tradition, transforming bycatch and trimmings into valuable feed and supplements. In North Holland’s Amsterdam, where innovative startups blend with established firms, or South Holland’s Rotterdam, Europe’s largest port handling vast seafood imports, these processes generate emissions heavy with ammonia, hydrogen sulfide, and organic volatiles from rendering and drying stages.
The humid Dutch climate, coupled with stringent air quality needs in densely settled areas like Gelderland and Limburg, demands systems that handle moisture without efficiency loss. Facilities in Zeeland’s coastal zones, leveraging proximity to North Sea fisheries, face additional challenges from saline influences accelerating corrosion.
Our configurations include pre-scrubbers for sulfur compounds, achieving high destruction rates while reusing captured heat for evaporators, supporting the Netherlands’ circular economy in marine resources.
Distinctive Elements of RTO Use in Fish Meal and Fish Oil
In fish meal and fish oil extraction, exhaust flows carry proteinaceous aerosols, fishy odors from trimethylamine, and corrosive sulfides, with concentrations varying 0.5-5 g/Nm³ and volumes 10,000-60,000 m³/h. Dutch processors in Brabant or Overijssel, integrating with aquaculture feeds, require units resistant to bio-fouling from sticky residues.
The intermittent rendering batches cause load swings, calling for RTO with flexible turndown. In Utrecht’s logistics hubs, where space is at a premium, compact designs minimize disruption during upgrades.
Beyond basics, the cultural emphasis on fresh seafood means RTO must curb odors effectively, our low-leakage valves ensuring community harmony in urban settings like The Hague.

Essential Elements and Consumables for RTO in Fish Processing
Ever-Power RTO for fish meal and oil encompasses vital components like structured ceramic media (for heat storage, tolerant to amines), rotary valves (for flow reversal, 2-year span), auxiliary burners (for startup), and induced draft fans (for exhaust pull). Consumable items such as valve gaskets and filters need replacement every 4-8 months to resist bio-corrosion.
Drive components, including motors and gears, assure smooth function. Add-ons like wet scrubbers neutralize acids, crucial for protecting against fish-derived corrosives in Dutch humid ports.
Reviewing RTO Choices for Fish Meal and Fish Oil
In fish processing, evaluate systems like Haarslev™ with solid odor control but fixed setups, or Dürr™ providing 96% TER though with adaptation needs for saline. (Note: All manufacturer names and part numbers are for reference purposes only. EVER-POWER is an independent manufacturer.)
Ever-Power parallels with enhanced anti-fouling, offering edges in the Netherlands’ marine-focused economy.
International and National Regulatory Setting for Fish Processing
In the Netherlands, fish meal and oil processors follow Dutch Emissions Guidelines (NEa) and EU IED (2010/75/EU), capping VOCs at 50-100 mg/Nm³ and odors via BAT. Provinces like Friesland enforce water-related emissions, while Zeeland monitors coastal impacts. 2025 guidelines emphasize sustainable sourcing under EU Common Fisheries Policy.
Neighbors: Germany (TA Luft) requires 98% H2S reduction; Belgium (VLAREM) targets amines; Denmark mandates BAT for processing.
Globally, top producers: Peru (guidelines mandating RTO); Mauritania (export standards); Iceland (EEA fish oil rules); China (GB 37823-2019 on odors); USA (EPA NSPS for PM); Chile (DS 138 environmental); Norway (sustainable fisheries acts); Barbados (vital food source regs); Vietnam (QCVN 19:2021); Thailand (Notification B.E. 2549); India (CPCB norms); Indonesia (Ministerial 5/2021); Morocco (export HACCP); Senegal (export to EU rules); Russia (Federal 7-FZ); South Africa (NEMA AQA); Mexico (NOM-043); Brazil (CONAMA 430); Japan (Air Pollution Law); Canada (CEPA); Australia (NEPM); Turkey (Industrial Air Reg); Saudi Arabia (RCER); UAE (Law 24); Egypt (Law 4/1994); Argentina (Resolution 177/07).
Associated fields, such as aquaculture feeds in Rotterdam or omega-3 extraction in Amsterdam, use RTO to meet these, with instances in Germany’s Baltic coast or USA’s Alaska underscoring parallel demands.

On-Site Accounts and Deployment Insights
Guiding an upgrade at a fish oil extractor near Rotterdam’s Europoort, our RTO lowered sulfide emissions by 97%, with recaptured heat aiding evaporation units. As the field lead, I fine-tuned the scrubber to handle peak loads from herring seasons, preventing corrosion that plagued older setups and keeping production steady through Dutch winters.
At an Amsterdam-based meal plant repurposing bycatch, the RTO tackled amine odors, dropping complaints from nearby districts. From direct oversight, calibrating the LEL sensors during trials averted risks from volatile surges, echoing challenges in compact urban processors.
Overseas, a Danish Aarhus facility mirrored this, with RTO enabling higher throughput without eco backlash, akin to Belgian Ostend cases prioritizing odor abatement.
