Electronic scrap

Our customized solutions enable you to efficiently shred electronic scrap in your recycling facility and they align perfectly with your recycling system. The granulate size is adjusted such that metals and non-metals can be separated and recycled as best as possible.

More than 40 million tons of electrical and electronic scrap are generated annually – and the trend is growing dramatically! Recycling electronic devices is not just beneficial for environmental reasons. This scrap, as a rule, contains many precious metals that are recovered during the recycling process. To ensure a high yield during the recovery process, the shredding should generate only a very low amount of fine particles.

Our low-speed, 4-shaft shredders are particularly suited for this process. The low speed ensures that circuit boards and old devices are carefully shredded with low emissions. The recycled material is ideally suited for e-scrap recycling machines and subsequently for cutting facilities where precious metals are separated from their impurities.

The shredded and processed electronic scrap is sorted into its various components by downstream separation technology to recover valuable recyclable fractions. Our rotary shears are first choice for a careful processing of electronic scrap with a low content of fine particulate matter. 

Old devices are processed in various shredding and separation phases to ultimately generate marketable fractions. Regardless of whether an old PC or a broken household device is to be recycled – our shredders ensure reliable, and, first and foremost, economically efficient shredding.

Leading plant manufacturers in the field of refrigerator recycling trust in our reliable shredding machines. Our rotary shears are used for shredding cooling units. They are convincing with their sturdiness, low speed, low maintenance expenditures, and compact design. 

Circuit boards and computer chips often contain large amounts of precious metals. It is possible to recover these valuable precious metals by shredding, sorting and smelting. UNTHA shredders set the industry standard for recycling circuit boards thanks to their rugged construction and very low dust generation.
