IFAT 2026 : WEIMA presents new high-torque drive for waste shredders and a dewatering press

The WEIMA W8.15 PowerLine is a robust industrial single-shaft shredder designed for reliable waste shredding in recycling facilities and for producing refuse-derived fuel (RDF) on an industrial scale. Within the PowerLine series, the W8.15 represents the compact entry-level model with a working width of 1,500 mm and has proven itself many times over in primary or secondary shredding applications. Typical input materials include mixed commercial waste, municipal solid waste and processed residual materials, as well as high-calorific fractions from RDF production.

Its robust rotor design, variable screen concepts and different drive options ensure consistent, high-throughput shredding. Thanks to its user-friendly design and high level of process reliability, the W8.15 PowerLine offers recycling companies an economical, reliable solution that can be easily integrated into existing plants and recycling concepts.

For its presentation at this year's IFAT, the W8.15 PowerLine has been fitted with a high-torque drive including a servo controller – a new development by Baumüller in collaboration with Nidec Desch. This direct-drive solution has been specifically developed for applications involving difficult-to-shred materials. The high-torque motor provides exceptionally high torque even at low rotational speeds. Thanks to precise coordination between the drive and rotor shaft, power transmission is optimised, achieving torque levels of up to 61,000 Nm. At the same time, the innovative drive concept enables energy-efficient, economical and sustainable operation.

Across the entire W8 series of WEIMA shredders, maximum flexibility is offered. Depending on customer requirements, different drive concepts can be selected to optimally adapt the machine to individual processes. A hydraulic drive is particularly recommended for applications involving fluctuating loads, ensuring high torque with comparatively low kW power consumption. The classic electromechanical direct drive stands out for its high energy efficiency and low maintenance requirements.

WEIMA does not view waste management as a series of individual solutions, but as an ongoing process. For this reason, the company relies on a proven network of specialist partners in conveying and extraction technology, sorting and recycling systems, and energy solutions. Together, WEIMA and its partners implement bespoke plant concepts, covering everything from shredding and material conveying to sorting and integration into downstream production processes. The result is holistic solutions that are precisely tailored to the requirements of the waste and circular economy.

"Our customers expect powerful machines and intelligent, interconnected process solutions. With the W8.15 PowerLine, the high-torque drive from Baumüller, and our strong partner network, we demonstrate how we consistently exceed these expectations,” says Erik Hagen, WEIMA's Sales Director.

As one of the world’s largest meetings places for environmental technologies and water management, IFAT 2026 is the perfect opportunity to showcase dewatering solutions. With the C.200 dewatering press, WEIMA demonstrates how wastewater, sewage sludge and other moist residual materials can be efficiently dewatered and reduced in volume. The press on display at the trade fair shows how mechanical dewatering can be seamlessly integrated into existing waste and water industry processes.
