Siempelkamp is offering the appropriate cleaning technology or machine for every foreign material and potential impurity that needs to be removed from the material flow before the pressing process.
Sustainability, efficiency and responsibility are particularly important to the Siempelkamp Group’s approach to recycling in the production of MDF and particleboard. Consequently, recycling solutions for the wood-based panel industry will therefore be a topic central to Siempelkamp’s presentation. Maximum energy efficiency and cost-effectiveness with consistently high product quality are essential to the production of wood-based panels – and for Siempelkamp a reason to provide additional recycling support that stands out for its synthesis of all three requirements to customers. Siempelkamp is offering new recycling concepts for both particleboard and MDF production.
MDF Recycling
“This approach is completely new and represents a genuine innovation in our industry. Unlike the recycling process for particleboard production, this is not just about separating wood from other materials. Recycling in the MDF process focuses rather much more intensively on the production of fibres as well as cleaning,” says Moritz Schränkler.
Siempelkamp’s new drying process aims to return fibre based materials in any form, gluing and finishing – e.g. from flooring, kitchen fronts and back panels – to the process. Irrespective of how the original fibre board made of MDF, thin MDF or HDF was processed: Siempelkamp’s recycling process breaks the material down into fibres and separates them from foreign materials and other impurities, such as paint, coatings and fittings. Besides the technical benefits that it delivers, the process also focuses on reducing energy consumption and helping the end products deliver outstanding performances and cost-effectiveness.
The concept has been secured on the basis of extensive tests with all common types of input materials that have been carried out by at Siempelkamp’s R&D center and external institutes. “We see the fact that it’s also possible to use our process to recycle PMDI-glued boards as a unique selling point. It means that the name of 'Siempelkamp' stands for the fact that we’re genuinely able to process all common input materials that are permitted by the German Waste Wood”, says company.
Recycling for Particleboard Production
“We’re following on from the successful launch of the first generation by taking another step and tailoring our services even more precisely to our customers’ needs in 2025. These modules have been adapted to the respective recycling raw materials that our customers specifically use and ensure an individually designed sorting process,” says Ulrich Kaiser, Head of Sales Wood Division.
Siempelkamp is offering the appropriate cleaning technology or machine for every foreign material and potential impurity that needs to be removed from the material flow before the pressing process. Such valuable foreign materials as metal, glass, plastic, paper and stones are sorted by type in order to obtain the purest possible grade of wood. It then is possible to reuse this wood in the particleboard industry while the foreign materials are directed towards their own recycling streams. All of which contributes to the realization of a sustainable circular economy. It’s also possible to simulate material flows and impurities for planning in advance.
