Dutch breakthrough in the recycling of contaminated metal

The Dutch recycling company ‘Purified Metal Company’ wants to build a state-of-the-art facility in Delfzijl (The Netherlands), to recycle contaminated steel scrap into high-quality raw material for the steel industry. This novel recycling facility will neutralise most pollution present and brings down CO2-emissions when compared to steel from iron ore.


Delfzijl (The Netherlands), 12 May 2017. With the signing of the land lease agreement between Groningen Seaports and Purified Metal Company this week, the first step is taken towards state-of-the-art metal recycling in North of Holland. The factory covers 3.8 hectares of ground in the immediate vicinity of the recently opened solar panel park.


Purified Metal Company is the first company in the world who developed a patented process to safely recycle steel scrap containing asbestos. In the melting process, the contaminated steel reaches a temperature of 1,500°C (2732°F). Hereby all the hazardous asbestos fibers are broken down into sand, glass and magnesium oxide. The fully-sealed recycling factory is specially designed to guarantee human and environmental safety during the processing and transportation. To further guarantee this safety, only proven and reliable techniques from other sectors are used in the factory.


Groningen Seaports and alderman Rijzebol of the municipality of Delfzijl are very pleased with the arrival of this world-leading factory. "The licensing ensures that this is an unquestionably safe procedure for both the people who work there and the environment. The essence of the circular economy is closing material flows. That fits well in our vision of sustainability. Therefore, we are proud that Purified Metal Company has chosen the location of Delfzijl", says alderman Rijzebol. He continues: "The recycling of steel also has a huge impact on the total CO2-emissions. Therefore, Purified Metal Company fits very well in the Green Harbour Vision 2030. In addition, the creation of 70 jobs is very welcome."


Purified Metal Company is currently in the process of applying for all the necessary permits within the environmental rules and regulations. The Dutch company hopes to start construction before the end of 2017.

The concept engineering of the first plant of PMC has been completed. PMC has worked together with two leading partners towards this goal. Küttner GmbH was responsible for the process and plant engineering and Royal HaskoningDHV conducted the civil engineering part.

Küttner, who has also been involved in the study of the Technical University of Aachen, has expressed full confidence in the process. Thereby Küttner will deliver the plant on a turnkey basis and guarantee the operation of the plant and a clean, free from asbestos scrap product, the Purified Metal Blocks ™.

With the completion of this phase the operating costs of a working factory have been calculated and the level of investment required is known. Also wonderful 3D models have been made of the future plant.

The completion of this phase, showing the feasibility of the PMC process, represents a crucial step towards the realization of the first factory. The insight into the operational costs and the necessary investment have been translated to a solid financial model. These results lead to confidence among local and regional officials and potential investors.

The last year Purified Metal Company has entered into a partnership with the Technical University of Aachen. The RWTH Aachen is a leading institute in the field of metallurgy and has a laboratory with furnaces capable of melting up to 500 kg of steel. The purpose of the co-operation was to perform a validation study.

Purified Metal Company has asked the university to examine whether the PMC process is suitable for treating asbestos contaminated steel to assure that asbestos fibers are destroyed and a clean steel product will be produced. Professor Schenk has supervised the project and is known worldwide for his knowledge and holds the chair of Metallurgy of Iron and Steel. He is regarded as one of the most eminent professors in his field.

The results of the study were recently issued by the university. The report is comprehensive, however the content of the report can be summarized as follows:

  • The University RWTH Aachen confirms that the temperatures and conditions in the PMC process ensure decomposition of asbestos fibers;
  • The result of the decomposition, the sand and glass-like product, will for the most part be contained in the slag. This slag arises as a byproduct  during the melting process of the contaminated steel scrap and can be certified as a useful building material after separation from the melt;
  • The liquid steel in the melt is free of impurities and can be used as a useful raw material;
  • During the loading of the furnace asbestos fibers that are being released are captured by an exhaust gas cleaning system. The fibers can be destroyed by means of post-combustion or caught by filtration.

The favorable results of the research are used for the engineering of a plant on an industrial scale. The results of this engineering process are expected soon.
