E-waste is devouring the earth's environment at a rate of 53 million tons per year, in which used 

circuit boards, as the value and toxicity of the coexistence of the special existence of the global 

environmental protection industry has become the focus of attention. The emergence of circuit 

board recycling equipment for this ecological crisis provides an innovative solution, and its core 

technology is reshaping the landscape of the electronic waste disposal industry.


Core equipment in the e-waste revolution


Modern circuit board recycling equipment has broken through the technical bottleneck of traditional 

physical sorting to form a multi-dimensional treatment system. Eddy current sorting system can 

accurately separate metal and non-metal materials, sorting accuracy of more than 98%, processing 

efficiency of 5 times higher than traditional equipment. The high-voltage electrostatic sorting device 

realizes efficient capture of micron-sized metal particles by establishing a strong electric field of 

20-100kV/m. The intelligent control system integrates IoT technology to monitor the operating 

parameters of the equipment in real time and automatically adjust the processing flow to ensure 

that the metal recovery rate is stable at over 95%.


The pyrolysis system adopts low-temperature anaerobic cracking technology to decompose the 

resin substrate within the range of 400-600°C. The metal recovery rate is 30% higher than that of 

the traditional incineration method, and the emission of dioxin is completely eliminated. Precious 

metal purification module using a combination of hydrometallurgical processes, through 

multi-stage leaching, electrolytic refining and other processes, can be extracted from each 

ton of waste circuit boards 300-500 grams of gold, the purity of which reaches 99.95% of 

the international standard.


The economic value code of green recycling


The new recycling equipment makes the circuit board resource rate break through the 90% mark, 

and the annual processing capacity of a single production line can reach 5,000 tons. From the 

economic point of view, each treatment of 1 ton of waste circuit boards can produce 300 kilograms 

of copper, 100 grams of gold and palladium, silver and other precious metals, the comprehensive 

gain of more than 20 times the traditional landfill disposal. In terms of environmental benefits, 

the energy consumption of equipment operation is reduced by 40%, the recycling rate of wastewater 

reaches 98%, and the emission index of waste gas is better than the EU environmental protection standard.


Driven by technological innovation, the cost of metal extraction has dropped by 60% compared 

with ten years ago, and the efficiency of precious metal recovery has increased by 45%. The 

modularized design of the equipment makes the capacity expansion more flexible, and 

enterprises can freely combine sorting, crushing and purification units according to the

 processing scale, and the payback period is shortened to 18 months. This economic 

breakthrough is attracting more capital into the field of circular economy.


The road of industrial upgrading of intelligent manufacturing


Industry 4.0 technology is deeply implanted in modern recycling equipment, and the digital twin 

system can simulate and predict the performance of equipment, reducing the failure rate by 70%. 

The cloud-based big data platform analyzes price fluctuations in more than 30 metal markets 

around the world in real time and automatically optimizes production solutions. The visual recognition 

system uses deep learning algorithms to accurately recognize more than 200 electronic components,

 increasing the sorting accuracy to 99.3%.


The equipment manufacturer is building a full life cycle service system. The remote diagnostic system 

can respond to fault declarations within 2 hours, and preventive maintenance extends equipment 

service life by 40%. The energy consumption management system dynamically adjusts the power 

of the equipment to keep the energy consumption of tons of processing within 80 kWh, which is 

35% lower than the industry average.


The technological innovation of circuit board recycling equipment is giving rise to a hundred billion 

circular economy market. With the increasingly stringent environmental regulations in various 

countries, this fusion of intelligent manufacturing and green technology equipment, not only 

cracked the electronic waste disposal problems, but also opened up a new era of sustainable 

utilization of resources. Driven by the goal of carbon neutrality, this field will continue to attract 

technological innovation and capital investment, providing key support for global sustainable 

development.
