ARN Recycling

From shredder
waste to reusable
material

ARN Recycling’s mission is to reprocess shredder waste into reusable products and thus contribute to achieving the recycling percentage of 95% in 2015, as specified in European Directive 2000/53/ec. In order to achieve this goal, ARN Recycling is building a post-shredder technology (PST) facility in Tiel.

Events in 2009

Completion of the processing line is scheduled for 2010. The year 2015 seems a long way away now, but over the remaining five years the processing line will be optimized. This optimization concerns three targets:

These targets have been defined for the shredder waste obtained from Dutch end-of-life vehicles, which amounts to 33,000 tonnes a year. As the PST facility will have a total capacity of 100,000 tonnes, it will be able to process over 60,000 tonnes of additional shredder waste. The facility will thus make a substantial contribution to limiting the amount of land-filled waste in the Netherlands.

Progress with PST facility construction

The construction of the processing building was completed in 2009. The building comprises offices, a bunker hall for shredder waste (1,500 m2 floor area) and a production hall (2,200 m2 floor area), and meets all environmental and safety requirements. Both halls have a liquid-tight floor and a sprinkler installation with a fire extinguishing water storage capacity of nearly 1,000 m3.
The office section was fitted out and furnished at the end of December 2009. The workshop was also equipped. Equipment, fixtures and fittings for the laboratory are awaited.

Progress with processing line

Because of the innovative nature of the processing line, it took a lot of time, energy and money to bring together all the theoretical and practical knowledge required. Plenty of hard work was done on the design together with Topec (main contractor; part of the Pon Group) and the German engineering firm SiCon (designer); from a comparable project the Austrian company TBS GmbH provided a lot of practical knowledge. The outlines of the processing line were decided upon at the beginning of December. The first machines were ordered in February 2010.

Cooperation with shredder companies

Consultation with the shredders was intensified in 2009. The market situation that will exist after the processing line in Tiel comes into operation was discussed during various meetings. Solutions are being worked out in consultation with the shredders and the dismantling companies in order to avoid unfair competition from companies working with end-of-life vehicles that are outside the ARN system. The problem can be solved effectively by initiating various joint actions.

End fractions market research

There are markets for the three most important end fractions:

  1. The minerals (25%) are used as fillers to prevent subsidence of German salt mines
  2. The fibres (22%) are used as additives in dewatering sewage sludge
  3. The low-chlorine plastic fraction (20%) is injected into a blast furnace to replace coke in the reduction of iron oxide to steel.

Markets for end fractions

The application of the minerals has been recognized by the Dutch government as ‘material reuse’. However, the government considers the application of fibres and the low-chlorine plastic fraction as only ‘reuse with energy recovery’. ARN Recycling is therefore looking for alternative markets.
It is not easy to find an alternative for the plastics, as various types of plastic are used in vehicles. This hinders efforts to find a market. ARN is therefore taking a different approach, namely the further separation of the plastic flows, which will create more applications. Higher added value methods are being investigated for the minerals that make the material suitable as a raw material, for example in road building or as a filler in such products as bricks or tiles.

Outlook for 2010

The processing line will be operational in 2010. The machines have been ordered and preparations have been made to install them in the production hall.

A number of new employees will start up the installation in the initial months of the year. The processing line is scheduled to achieve the desired production level of 33,000 tonnes a year at the end of the year, after an intensive test programme has been carried out.

The processing line’s plastics module will be expanded so that a substantial portion of the plastics can be recovered. Some additional research will be done for this. The processing line will be equipped with a machine monitoring system, which can detect the wear of components at an early stage. In this way malfunctions in and damage to the line can be prevented.
ARN gives high priority to cleanliness in the facility. Among the measures to be taken is the installation of an air purification system in the main processing building, which will extract and capture as much as possible of the dust that is emitted during the separation process.
