C&D Waste Recycling Solutions
Industrial Shredders
Materials that are difficult to process and reduce in volume and are, in many cases, economically ‘unshreddable’. From problematic skip waste to demolition material – such as wood, non-ferrous extrusions, composite panel work and structures – this is typically unsorted, which can add an additional dimension of complexity for operators. UNTHA’s new two-shaft shredder: the ZR, unveiled in the UK in September 2021, comprises two machines – the ZR2400H and ZR2400W – which have been specifically engineered for multi-shift, continuous pre-shredding, even when handling difficult materials. Modular, quick-change cutting table design. Supplied with the UNTHA Eco Power Drive with water-cooled synchronous motors to reduce energy consumption by up to 75%.
Sorting Systems
USA Recycle needed its own system to divert materials from landfills while obtaining high purity levels. The objective was to quickly and efficiently remove materials from the waste stream and reuse them in new products. Machinex 50-tonne-per-hour system is designed to sort recycling valuables such as cardboard, metal, wood, aggregates and fines from construction and demolition residue. System includes a vibrating conveyor, a MACH Trommel and two cross-belt magnets. Finally, an air separator removes light materials from heavy ones. The ability to pick wood at multiple sorting stations makes recovery of a large quantity of wood possible and the dense out units are excellent at removing lightweight contaminants and allowing for easy quality control of the heavy fraction.
Mobile Crushers
For demolition work in an inner-city area, there are Rubble Master’s mobile crushers. High-quality recycling material for various applications is produced from C&D waste, concrete residues or asphalt. The crushed material can be used for the substructure of roads, for example, and also for admixture in the new production of concrete or asphalt. Mobile crushers from Rubble Master are used in inner-city areas in particular and enable on-site recycling, helping to save countless truck trips. With electric drives and new digital services, Rubble Master is setting standards for reducing energy and noise, and also for meeting current and future legal requirements.
Autonomous AI-based robotic sorting
Costly and inefficient manual processes and rigid plant set-ups, lack of data on waste and sorting results, and health hazards and injuries for employees are common challenges with C&D waste recycling. The AI-powered ZenRobotics Heavy Picker sorting robot runs unmanned and uninterrupted 24/7. Autonomous operations extend sorting capacity and efficiency with low operating cost. The robot picks multiple high-quality recyclables like wood, plastic, metals and inert materials with up to 6,900 picks per hour and 99% purity. System is flexible to use, easy to install and operate. propertyandbuild.com 45
