BHS-Sonthofen will be focusing on metal recovery from metal-containing waste materials such as electric and electronic scrap (WEEE), incinerator bottom ash (IBA) and automotive shredder residue (ASR) at this year’s Ifat (Booth B4-351/450). A second focus topic is the efficient and safe recycling of lithium-ion batteries.

BHS-Sonthofen’s mission is ‘Transforming materials into value’, meaning to extract the full economic value from various materials. The company will be splitting its booth into different topic worlds and showcasing how it is fulfilling this mission in both the recycling of metal-containing residual and waste materials on the one hand and in battery recycling using its in-depth process expertise on the other hand. The company’s innovative, efficient recycling solutions are the result of its broad technology portfolio, tests in its in-house test center, system engineering and international project management, combined with decades of experience.

In recent years, BHS-Sonthofen has continuously invested in development to further improve metal recovery from a wide variety of input materials. Depending on the material, the firm offers an optimized process tailored to its customers’ individual requirements, along with the core machines needed from its own production.

French company Envie, located in the southern city of Toulouse, is the most recent customer to benefit from the implementation of a metal recovery solution. Envie specializes in the recycling of waste of electrical and electronic equipment (WEEE). In 2023, the customer expanded its capacities and markedly enhanced the quality and quantity of its output with the introduction of a new plant, featuring the BHS Pre-shredder and Rotorshredder (type RS).

Battery recycling now plays a key role in the development of sustainable energy storage solutions. A few years ago, BHS-Sonthofen developed a new, safe process for the efficient recycling of lithium-ion batteries, which has since proven to be a success on a production scale with several customers. The mechanical drying process occurs within a protective atmosphere and comprises three main stages: shredding, vacuum drying, and sorting. The drying process is supplemented by condensation for electrolyte recovery and gas purification. These three stages have now reached a high level of maturity that they are offered as pre-configured standard modules. The process allows valuable raw materials concentrated in black mass such as lithium, nickel, cobalt, and manganese to be returned to the material cycle at a rate of more than 97 %. In addition, a high proportion of recyclable materials such as aluminum, copper and iron can also be recovered, mentions the firm. Visitors can find out more about the process and the solution at its dedicated topic area.

The firm is the only provider that covers all the key process steps in mechanical battery recycling on a technological level, uniquely offering the relevant process modules from a single source. Customers benefit from its extensive experience and the combined process expertise in processing and traditional process technology, adds the company.

Comprehensive portfolio of machine technologies and systems

BHS-Sonthofen offers a comprehensive range of machine technology and full-scale plants, including separation and screening technology, for the efficient processing and pre-/post-shredding of valuable waste materials. The latest product development for pre-shredding is the Rapax, a powerful, universally applicable pre-shredder that combines design and functionality, opines the company. A versatile and sturdy machine, the Rapax is particularly suitable for processing various metal fractions and e-scrap, as well as commercial and industrial waste. When it comes to pre-shredding batteries, the Rotary shear type VR is often used as a powerful twin-shaft shredder. The Universal Shredder (NGU) single-shaft shredder is used for pre- and post-shredding a wide variety of materials that can be cut, such as non-ferrous light metals, batteries, data carriers, cables, and refuse-derived fuels. The further development of VR and NGU into fully inertizable and gas-tight machines – developed specifically for the reliable shredding of batteries – is also worth a special mention here, shares the firm.

When it comes to the specialized selective shredding of e-scrap or light metal scrap, the firm offers the low-maintenance and durable Rotorshredder (RS), which selectively shreds, isolates and cleans the input material using impact, shock and shearing forces. Metal components are optimally dissolved and particle sizes are reduced in a targeted manner, states the firm. The high-performance Rotor impact mill (RPMX) crusher also reliably isolates different materials from pre-crushed, metal-containing material composites and removes cable sheathing and other adhesive substances from metals, informs the company. Shaping the metals into balls facilitates their separation by type.
