E-Waste Recycling Solutions: PCB, PV Panels, and Lithium Batteries

The rapid growth of electronic products, electric vehicles and renewable energy systems has led to a significant increase in electronic waste, especially waste PCB boards, retired solar PV panels and spent lithium batteries. These materials contain valuable metals and reusable resources that can be recovered instead of being discarded. With increasingly strict environmental regulations and growing demand for recycled raw materials, efficient e-waste recycling has become both an environmentally responsible choice and a profitable business opportunity. DOING provides complete recycling solutions for these three major categories of e-waste, helping customers maximize resource recovery while meeting environmental standards.

Electronic waste recycling

Waste PCB Board Recycling Solution

Waste PCB boards contain a variety of valuable materials, including copper, aluminum, iron, precious metals and resin fibers. Among them, copper is one of the most valuable recyclable materials and can be directly reused in the production of new electrical products after recovery. For PCB boards with electronic components, DOING also provides electronic component dismantling machines to separate the components before recycling, improving the recovery efficiency and purity of subsequent processing.

DOING waste PCB board recycling machine

DOING PCB board recycling equipment employs a dry, multi-stage physical crushing and separation process. Waste circuit boards are first crushed into suitable particle sizes, then undergo multiple separation processes including magnetic separation, air separation, and electrostatic separation, efficiently recovering various materials. Copper recovery rate exceeds 98%, with a purity of over 99%. Other recycled materials can also be collected for further utilization, achieving comprehensive resource recycling without chemical pollution or wastewater discharge. Our production lines are available in capacities from 100 kg/h to 1000kg/h, with 100 kg/h and 200 kg/h models among the most popular choices.

The equipment features stable operation, low energy consumption, effective dust collection and PLC intelligent control, making it suitable for processing various waste circuit boards from household appliances, communication equipment, computers and other electronic products.

Solar PV Panel Recycling Solution

As large numbers of solar panels reach the end of their service life, efficient recycling has become increasingly important. DOING solar panel recycling equipment can process monocrystalline silicon, single-glass, and double-glass solar panels. We also offer three different solar panel recycling solutions to meet different production capacities, investment budgets and recycling requirements.

Fully Automatic Solar Panel Recycling Line

The fully automatic production line adopts a complete physical dismantling and separation process. It automatically removes the aluminum frame and junction box before crushing and sorting the remaining materials. Compared with thermal treatment, the physical recycling process consumes less energy, operates more efficiently and is more environmentally friendly. More importantly, it can effectively preserve the silicon wafers, creating greater recycling value while recovering aluminum, glass, copper and other materials.

Semi-Automatic Solar Panel Recycling Line

The semi-automatic production line also uses physical separation technology and delivers high recovery efficiency with a lower equipment investment. Although it requires more manual participation during dismantling, it remains an economical choice for customers with medium processing capacity or limited budgets. It can still achieve efficient recovery of aluminum frames, glass, silicon and metals.

Tunnel Furnace Recycling Line

The tunnel furnace production line removes the EVA encapsulation layer through controlled heating before subsequent material separation. Although its energy consumption is relatively higher, it offers large processing capacity and more thorough EVA removal, making it particularly suitable for customers with high annual processing volumes. This process helps improve the recovery quality of glass, silicon cells and other valuable materials.

DOING tunnel furnace recycling equipment

Whether customers choose the fully automatic line, semi-automatic line or tunnel furnace solution, DOING provides reliable equipment to efficiently recover aluminum, glass, silicon, copper and other valuable materials from waste solar panels, helping maximize recycling value according to different production needs. Our solar panel recycling lines are available in capacities from 700 kg/h to 1000 kg/h, with customized configurations available for different project scales.

Lithium Battery Recycling Solution

Used lithium batteries contain valuable materials such as copper, aluminum, iron, and black powder. Our equipment is suitable for recycling various lithium batteries, including ternary lithium batteries, lithium iron phosphate (LFP) batteries, mobile phonelithium batteries, plastic shell batteries, soft lithium batteries, cylindrical lithium batteries. Proper recycling not only reduces environmental risks but also provides important recycled raw materials for battery manufacturing.

Recyclable waste lithium batteries

To ensure safe operation, used lithium batteries must undergo pretreatment before entering the formal recycling process. This involves fully discharging the batteries and then allowing them to air dry or bake them to reduce potential safety risks. After pretreatment, the batteries enter the recycling production line, where they undergo multi-stage physical crushing, screening, and separation.

Lithium battery discharge pretreatment

DOING lithium battery recycling equipment adopts dry physical separation technology, integrating shredding, crushing, magnetic separation, air classification and screening into one complete process. The recovery rates for copper, aluminum and black powder all exceed 98%. The recovered copper and aluminum can be directly recycled, while the recovered black powder can be further refined to recover valuable battery metals. The entire production line is equipped with dust removal, exhaust gas treatment and multiple safety protection systems to ensure safe, clean and environmentally compliant operation. Our standard production capacities range from 500 kg/h to 1000kg/h, with customized solutions available for different battery recycling projects.

Advantages of lithium battery recycling equipment

All DOING recycling equipment is equipped with PLC intelligent control systems, allowing centralized operation and real-time monitoring of the entire production process. Most production lines require only one or two operators for continuous operation, significantly reducing labor costs while improving production efficiency.

Environmental protection is also fully considered in our equipment design. High-efficiency dust removal systems, exhaust gas treatment devices and enclosed conveying systems effectively reduce dust emissions and maintain a clean working environment. The dry physical recycling process avoids wastewater generation and secondary pollution, helping customers comply with increasingly strict environmental regulations while lowering operating costs.

With extensive experience in overseas recycling projects, DOING provides much more than equipment manufacturing. We offer complete project support, including process design, plant layout, equipment manufacturing, installation and commissioning, operator training and long-term after-sales service. Whether you are building a small recycling workshop or a large industrial recycling plant, our engineering team can provide customized solutions based on your raw materials, production capacity and investment budget.
