VHB Groep (NRC and Aerinnova) strengthens its position in the United Kingdom with the strategic acquisition of Rock Solid BV

On the 28th of June, VHB Groep took a large and significant strategic step in the Europe wide field of responsible recycling and the recovery of valuable raw materials. The acquisition of the shares of well established companies Rock Solid BV (NL) and Rock Solid Processing Ltd (UK) enables VHB to offer and provide a more comprehensive and well rounded solution to customers.

Rock Solid was founded 17 years ago by Hans van Craaikamp and Peter Bleeker, specialising in the processing of IBA incinerator bottom ash, coupled with the sales and marketing of IBAA aggregates and recovered ferrous and non-ferrous metals.

Passion for raw materials
Rock Solid very much shares VHB’s passion for recovering valuable raw materials from IBA incinerator bottom ash, and on that basis, VHB are pleased to confirm that the current management of Rock Solid will stay on, ensuring a smooth transition for our customers and new clients alike.

History and Future
As a Dutch family business with a 90-year history, VHB Groep already has quite a past to look back on. With this step, VHB can further reinforce and secure its position for the future. Everyone at VHB looks forward to further growth and development together with familiar and new faces in the organisation, and VHB extends a warm welcome to all new staff joining from Rock Solid with the motto: ‘Welcome on board and to the VHB family’.


Sorting of non-ferrous metals based on density, shape and composition

When processing bottom ash, non-ferrous metal concentrates are recovered, a mixture of non-ferrous metals and adherent bottom ash mineral. These non-ferrous metal concentrates need to undergo further processing in order to obtain pure metal streams, which can subsequently be sold as high-grade raw materials.

Aerinnova specialises in the recovery of various metals from non-ferrous metal concentrates.  By applying innovative sorting techniques to specific fractions, Aerinnova succeeds in recovering non-ferrous metals with a high grade of purity. Aerinnova separates the various metals on the basis of density, shape and composition.

The separated metals such as aluminium, copper, brass and stainless steel are therefore ideal for supplying smelters. The residual bottom ash mineral can be used as a construction aggregate for making concrete or as a hardening material in road construction.

Aerinnova offers sustainable, cost-saving solutions whereby transparent work methods are paramount. This way we are able to offer our customers the highest possible value from the recovered metals.

Metals from waste

Innovative and sustainable solutions

Complete chain

Aerinnova can handle the entire chain : from coordination of required permits and administration,  transportation of non-ferrous concentrate, separation of non-ferrous concentrate, to the sale of the recovered metals.

Separation techniques

Aerinnova uses, among other things, magnetism, density and sensor technology to separate non-ferrous metal concentrates from 0 mm upwards.

Optimal yield

Optimal yield due to the high purity grade of non-ferrous metals, our customers have described our metals as being of extremely high quality!

Reusing non-ferrous metal

Circular Economy

Metals can be constantly reused as a raw material for new products. After the metals have been meticulously sorted, Aerinnova supplies the metals directly to customers in the metal industry in the Netherlands and abroad. Metal is remelted at various smelters back into raw materials for new products, which find their way back into the economy.

These recycling methods deliver CO2 savings of more than ninety percent compared to the mining of metals
