Searious and CirTec get under the skin of a fish!

New technology makes high-quality product from fish processing residuals

When you think of fish, you don’t automatically make a link with leather. Nevertheless, the skin of, for example, salmon, cod or haddock is an excellent raw material for sustainable production of exotic leather with the structure of a water snake. Searious BV from Beetgumermolen (Netherlands) has developed a technology to produce leather without chrome, brine and anti-fungal materials. CirTec from Purmerend (NL) supplies a core component in water treatment so that the unique production process becomes a closed system. Both parties will sign an agreement at the aquanederland trade fair to confirm their collaboration.

Leather made from fish skin is not new, in fact it has been around as long as humans have eaten fish. Even today, fish leather is increasingly produced because the main raw material is an upcycled material from a residual product from fish processing. However, if harmful substances are used when tanning leather, such as eg. chromium, brine and fungicides, an important part of the presumed sustainability is lost. This sustainability aspect has prompted Folkert Fennema of Searious to develop a tanning process, without waste. Fennema has been the driving force behind this development since 2016, a period in which he cooperated with several parties.

Belt out of salmon leather

The final challenge in sustainable fish leather tanning is the treatment of a liquid stream that still contains too much water to be useful again. That’s where CirTec comes in. By evaporating water using low-grade energy, a reusable concentrated raw material-rich stream with a positive value is created. The sum of technology results in a sustainable tanning process, in which a residual flow is converted into a high-quality product, without creating a waste flow. A development that is fully in line with Europe’s circular objectives.

Developing a beautiful product that is sustainable and innovative is one thing, but if the costs turn out to be too high, it is doomed to fail. Tanning fish skins according to the Searious method is both technically and financially feasible and thus combined with circularity and environmental benefit an important step forward,

Searious will build a prototype installation at its location in Leeuwarden this year, with all process steps integrated on a representative demonstration scale. The project started at the end of 2021 and will be completed by mid-2023. The realisation of a full scale installation is started when finalising this project.

The relationship between Searious and CirTec relates purely to the water paragraph, so the AquaNederland trade fair has been chosen for the official confirmation of the collaboration, and more specifically in the Innovation lane. CirTec is a participant in the fair and can be found at stand number L.108.

Used refurbished Giotto Greenland 2000 WR11 Beltpresses (2 pcs)

We have two Giotto belt presses with a belt width of 2,000 mm,  in excellent condition, for sale .

The WR Greenland belt press is specifically developed for the extensive dewatering of biological sludge. Due to a highly effective thickening zone, which is equipped with wedge-shaped plows,
free water releases quickly. In a wedge-shaped zone, sludge is then slowly put under pressure between two belts, after which it enters the final pressing zone. The first two rollers have an exceptionally large diameter and a perforated jacket, so that the pressure is built up slowly and evenly and water can escape quickly on both sides. In the further pressing zone, the pressure between the two belts is further increased, so that a maximum dry solids content in the sludge cake is achieved.

The available belt presses have an effective belt width of 2,000 mm and a pressing zone with 11 pressing rollers.

Docu-style film about recovering cellulose from sewage

The Water Alliance made a beautiful docu-style film about recovering cellulose from sewage and the transition in mindset to think from the perspective of resource instead of waste. When we think about climate change or how to reduce greenhouse gases, reuse of raw materials is a necessity. Cellulose recovery with CellCap and reuse of Recell are just one example.

Many thanks to: Water Alliance, Dr Mark Fletcher FREng, Noor Ney, Marit van Veen and Coos Wessels
