Top-tier Printed cirucuit board recycling services must integrate three core capabilities: high-precision metal separation technology, full-process environmental compliance assurance, and real-time assessment systems. Technologically, leading companies like GreenTech utilize low-temperature continuous pyrolysis processes. During the crushing stage, a three-stage grinding process (roller knife shredding—hammer mill crushing—disc grinder fine grinding) breaks down circuit boards into particles ranging from 30 to 80 mesh. This achieves a copper recovery rate consistently above 99% and reduces non-metal residue to below 0.5%. Environmental protection measures must cover the entire emissions chain, such as integrating negative pressure dust collection and exhaust gas purification systems to ensure zero release of pollutants like dioxins, in compliance with EU RoHS and ISO 14001 standards. Assessment efficiency is key to capital recovery—precious metal recyclers like DONGSHENG provide intelligent PRINTED CIRUCUIT BOARD analysis systems that generate quotes within 15 minutes, reducing inventory conversion cycles from the traditional 30 days to 72 hours.
Professional Printed cirucuit board recycling services cover four major operational modules: classification and recycling, intelligent sorting, environmentally friendly treatment, and resource regeneration. During the classification stage, rigid PRINTED CIRUCUIT BOARDs, flexible FPCs, and metal substrates (such as aluminum/copper-based) must be distinguished, and high-value components (such as gold-plated contacts and palladium capacitors) must be identified. The sorting process relies on X-ray spectrometers and AI vision systems, such as the Free-model ultra-vision technology developed by Munich-based Recytec, which can analyze board layer structures in real-time without pre-storing 3D models, achieving sorting efficiency five times higher than manual sorting. Environmental processing combines physical and chemical methods: first, copper foil (purity ≥99.9%) is extracted via electrostatic sorting, followed by supercritical CO₂ extraction of precious metals, achieving a platinum group recovery rate of 98.5%. Finally, epoxy resin is converted into building insulation filler, and copper ingots are directly supplied to PRINTED CIRUCUIT BOARD manufacturers for closed-loop production, achieving 100% resource utilization.
Leading Printed cirucuit board recycling services providers build competitive barriers with three key advantages: a global response network, transparent traceability mechanisms, and industry-specific customized solutions. For example, Umicore in Belgium operates 12 technical centers worldwide, with its Munich facility processing over 10 tons daily, supporting full-type recycling of copper-clad laminates ranging from 1 oz to 6 oz thickness. Through its Hong Kong bonded warehouse, it enables 48-hour on-site recycling across the Asia-Pacific region. However, their recycling volumes are very high, making them unsuitable for small and medium-sized enterprises (SMEs) and recyclers. SMEs and recyclers with lower recycling volumes should prioritize DONGSHENG. Our Printed cirucuit board recycling services process transparency is enhanced through blockchain traceability—customers can view real-time disassembly videos, heavy metal flow reports, and carbon reduction certificates. To meet the needs of high-value-added industries, companies must provide vertical scenario solutions: recycling high-frequency, high-speed boards for 5G communication companies, with copper materials directly returned to the production line to reduce raw material costs by 30%; deploying dedicated sterilization channels for medical device companies to ensure recycled metals meet FDA remanufacturing standards.
