MARKET LEADER NETHERLANDS
Thinking and acting sustainably!
HEROS Sluiskil B.V. has been part of the REMEX Group since 2012. Based in the Netherlands, the company focuses on mineral waste management, incinerator bottom ash processing, metal recovery and metal recycling. Its name is synonymous with recycling and recovery, and this is also expressed in the corresponding corporate motto: Think and act sustainably!
Professional waste management on 530,000 m²
The 53-hectare HEROS location in Sluiskil is situated in the Terneuzen Ecopark, on the canal from Ghent to Terneuzen, between the major ports of Rotterdam and Antwerp and the metropolitan areas of London and Paris. A large area in which innumerable raw materials and materials are transported by road, waterway or rail. Some of the recycled resources, including scrap and non-ferrous metals, travel long distances to the Far East, where many of the customers who purchase these secondary raw materials are now located. The central location, the deep waterway and the company's own quay also ensure excellent connections to Belgium, Germany, the United Kingdom and Northern France. Transferring material flows from seagoing vessels to inland vessels is part of the daily business here, as is the storage of bulk goods in open or closed silos and the treatment and interim storage of process water in the Tank Terminal Sluiskil (TTS).

Washing plant for incinerator bottom ash
On its premises, HEROS operates a washing facility for secondary aggregates made from incinerator bottom ash (IBA). The plant has been especially designed to fulfil the requirements of the Dutch Green Deal. It is optimised to meet the mineral requirements of the Dutch market and reduces the pollutant load of incinerator bottom ash. This allows the material to be used in construction products such as concrete and asphalt. An added benefit of the process is the additional recovery of valuable heavy metals. Water required in the operation of the plant is collected at all stages during the process. After physical and chemical treatment, the cleansed water is returned to the production process – thus reducing freshwater consumption to a minimum.

Dolphin completes the value chain
In addition to fine-grained non-ferrous metals, HEROS can also treat coarse-grained non-ferrous metals through its subsidiary Dolphin Metal Separation B.V., based in Harderwijk. The metal recycler specialises in the processing of coarse non-ferrous metal concentrates from incinerator slag and works with a sink-float process. The incoming material originates primarily from European recycling plants; the cleaned and processed metal batches are sold on the international metal market. In this way, the REMEX Group offers a fully integrated value chain for all metal fractions, encompassing all steps from recovery and cleaning to direct delivery to smelting plants.
From waste to recovery!
HEROS explains the Dutch recycling activities in relation to incinerator bottom ash. The process starts with the thermal treatment of municipal solid waste in waste incineration plants. This is followed by the processing of the remaining incinerator bottom ash in the HEROS plant. Both the extracted metals and the mineral secondary aggregates are recycled.
Core activities of the REMEX Group in the Netherlands
In the Netherlands, our company group is focusing on the management and processing of bottom ash from waste incineration and the recovery and cleaning of the metals contained in it. Up to 1 million tonnes of incinerator bottom ash are processed each year and the major part of the recycled raw materials are recovered. The most important products and services in brief:
Processing of incinerator bottom ash
A special category of construction materials is created at HEROS through the processing of incinerator bottom ash. In the past, secondary aggregates were mainly used in road construction, but new technological developments and intensive research have added further applications, e.g. in the concrete industry. Important clients are the highest Dutch road and water authority (Rijkswaterstaat), Dutch provincial authorities, project developers, concrete and asphalt manufacturers and construction companies.
Production of secondary aggregates
In the Netherlands, construction materials under the GRANOVA brand represent the sustainable use of incinerator bottom ash aggregates in a higher segment of the construction process chain.
The secondary construction material is ideal for replacing sand and gravel in concrete and concrete products. With the introduction of GRANOVA sub-brands, HEROS provides customers with a new sustainable alternative to primary construction materials.
Recycling of non ferrous metals
HEROS uses MERIT technology for the increased recovery of non-ferrous metals (non-ferro) in its bottom ash processing plant. The metals are then cleaned of adhering ash in their MTF Metal Treatment Facility. The result is an enriched non-ferrous concentrate of copper, aluminium, chrome, nickel, zinc, brass and precious metals. Furthermore, non-ferrous metals from other REMEX recycling plants are also processed here. After processing, the produced metal concentrates can be smelted directly. Since the takeover of Dolphin Metal Separation B.V., additional float-sink techniques are used to recycle aluminium, stainless steel and mixtures of heavy metals (copper, brass and zinc).
Recycling of ferrous metals
The HEROS site in Sluiskil also houses a unique processing plant for the purification of ferrous metals (ferro), which are recovered during the processing of incinerator bottom ash. The cleansed and copper-free scrap is then reused in various industries, including the steel industry.
Water treatment
On the HEROS site, there is the Tank Terminal Sluiskil B.V. (TTS) treatment plant, where both HEROS's own process wastewater and wastewater from third parties is treated. An integral part of the plant is the tank terminal. Heavily polluted wastewater can be pre-treated physically and chemically here. The acceptance of wastewater by lorry or ship only takes place after strict control. HEROS focuses on organically contaminated wastewater from industry, the recreation and leisure sector and the waste industry. New investments make it possible to reuse purified water. Ultimately, the result is processed water that is reused by industrial customers, i.e. a closed water cycle.
Storage and transshipment
The quay and storage facilities of HEROS are unique and of utmost importance for all operational processes. Ships with a draft of 8 metres can anchor at HEROS. The quay has a length of 500 m. A 150 m section is used for the service of tankers. In the port area, transshipment from sea to inland waterway vessels and vice versa takes place as well as the temporary storage of bulk material in open or closed silos.
HEROS Sluiskil B. V. is one of the industry specialists that offer incinerator bottom ash for high-quality use in construction products. The building material is produced with the corresponding CE marking and Dutch KOMO certificate.
