First REMEX plant for AMF waste goes into operation

Expansion of the Hilden recycling centre in Germany to include the treatment of artificial mineral fibre waste

Düsseldorf, 27.10.2025 – Following successful trial operations, REMEX GmbH has commissioned its first treatment plant for artificial mineral fibre waste (AMF waste). The new operating unit is located on REMEX’s approximately two-hectare site in Großhülsen in the west of Hilden (Germany).

Artificial mineral fibre waste is mainly generated during building renovation. The Federal Ministry for Economic Affairs and Energy estimates that around 12 million residential buildings constructed before 1979 need to be renovated in order to meet national climate targets. At the same time, landfill capacity in Germany is already limited, especially for hazardous waste.

“The safe management of construction waste is of macroeconomic importance. If, as politicians expect, half of all German residential buildings are to be renovated over the next two decades, we will need to use new processes to enable the efficient disposal of this waste,” explains REMEX Managing Director Michael Stoll.

The treatment plant in Hilden consists of a compactor with a downstream wrapping machine. The process line, which is located in a section of the 2,500 square metre hall, has a capacity of up to 20 tonnes per hour. With a pressing force of 120 tonnes, the volume of AMF waste is reduced by a factor of three to four. Compaction means that it takes up significantly less space when disposed of at landfill sites, thus optimising the use of landfill capacity.

The REMEX Group has been operating a construction waste processing plant on the site since last summer, processing household and bulky waste for the district of Mettmann. In June 2025, the amendment approval for Hilden was granted. On this basis, the company has now added the treatment, storage and handling of hazardous and non-hazardous aMF waste to its activities in the designated hall.

“As in Hilden, the REMEX Group is investing in its sites in order to meet the requirements of a responsible circular economy that combines a sustainable supply of raw materials with environmental and climate protection,“ explains Michael Stoll. ‘“But in order to fulfil our mission, we need support from politicians: faster approval procedures for recycling sites and the reform of Section 45 of the KrwG announced in the national action programme would be steps in the right directiong.“
