The risk of electronic product waste, the technical risk of recycling waste electronic products

Look at LS. The main thing is to pollute the environment, because the harmful metals in it will pollute the groundwater, soil...

Hello! We are glad to take orders for you, The hazards of electronic product waste are: 1. When electronic product waste is landfilled or incinerated, the heavy metals in it seep into the soil, enter rivers and groundwater, which will cause pollution of local soil and groundwater, and directly or indirectly cause damage to local residents and other organisms.

2. Electronic product waste contains mercury, under the action of microorganisms, inorganic mercury will be converted into methylmercury, through the enrichment of the food chain into the human body, will severely damage the nervous system, serious will cause death. 3. Electronic product waste will damage people's nerves, blood systems and kidneys, and affect the development of children's brains. Chromium compounds, especially hexavalent chromium, can damage the body's DNA and cause diseases such as asthma.

4. Destroy the ozone layer, cause the greenhouse effect, and increase the incidence of skin chain resistant skin cancer.

Electronic products are a broad general term that mainly refers to a product that operates on the basis of electrical energy. Like the mobile phones, laptops, tablets and smart watches that we use every day, these are all electronic products. In addition, plastics, metals, and batteries contained in electronic products are also electronic products.

Small electronic products such as mobile phones and laptops belong to the category of garbage, if we no longer need to use these electronic products, we can throw them into the trash can, and we can also do it through some legitimate channels.

There are some electronic products that contain plastic and metal inside, and these plastics and metals are also garbage. When throwing away electronic products, we have to do a good job of garbage sorting. Use tools to disassemble the electronic products, carefully remove the plastic and metal inside the electronic products, and then throw them into the corresponding trash can.

But the banquet is that the batteries in electronic products are heavy metals, which are toxic and harmful waste. When throwing electronic products, we should pay attention to take out the batteries inside the electronic products, and do not throw the batteries together with the electronic products into the garbage, otherwise it will cause certain environmental pollution.

However, like the No. 5 battery and the No. 7 battery, these two types of batteries are not heavy metals and do not need to be thrown into toxic and harmful trash cans. Batteries No. 5 and No. 7 are pumpless or low-pump batteries, which are dry waste and can be thrown away with our household waste. However, batteries and lithium batteries still need to be thrown into toxic and hazardous waste, because these batteries contain a lot of heavy metal substances, so we must distinguish them from other waste.

The hazardous waste of electronics factories mainly includes the following:

1.Acid waste liquid: corrosive waste liquid generated during the electroplating process, such as sulfuric acid, hydrochloric acid, etc.

2.Heavy metal residue: Materials containing heavy metals, such as cadmium, lead, mercury, chromium, etc., are often used in electronic products, and these materials will produce metal residue during processing.

3.Battery waste: Various batteries used in electronic products will produce harmful chemicals, such as acids, oxides, etc., during use, and these substances are harmful to the environment and human health if they are not properly disposed of.

4.Reactive solvents: In the production and cleaning process of printed circuit boards of electronic products, organic solvents such as ethyl acetate, acetone, phenols, etc., if not properly handled, can cause harm to the environment and the human body.

5.Flammable gases: In the production of electronic products, some processes require the use of high-purity, flammable and explosive gases such as helium and hydrogen, which can pose safety risks to workers and the surrounding environment if not handled properly.

Because these hazardous wastes are potentially harmful to the environment and human health, electronic factories need to dispose of these wastes in accordance with relevant safety regulations to ensure that they do not cause harm to the environment and human health. Treatment methods include strict collection, separation and treatment, such as neutralization of acid waste liquid, heavy metal treatment and treatment, battery specialization, etc. At the same time, the electronics factory should also strengthen the training and awareness education of employees, improve the awareness of employees on environmental protection and safety, implement a safe and environmentally friendly production process, and minimize the harm to the environment and the human body.

Hazardous waste from electronics factories includes, but is not limited to, the following categories:

1.E-waste (including batteries, monitors, wires and cables, televisions, computers and other waste electronic devices).

2.Cadmium, cadmium, gallium, aluminum, solar cells and other semiconductor products produced by copper selenate, acid, wastewater, etc.

3.PCB board scrap, solder mask, chemicals, etc.

4.Cadmium mercury battery production of waste acid, waste alkali, waste liquid, waste solid, etc.

5.Chromium-containing substances (e.g., pickling waste), mercury-containing substances (e.g., mercury silver switches), etc.

6.Waste acid, waste liquid, waste solid, etc. produced by semiconductors, electrical components, insulating materials, metal surface treatment, etc.

7.Waste generated during testing, testing and maintenance.

The above wastes contain high concentrations or toxic and harmful substances, which can cause serious harm to the environment and human health if not properly disposed of.

Hazardous waste from electronics factories includes: solder paste barrels, waste batteries, expired medicines, mercury thermometers, waste paint buckets, etc.

The hazardous waste identification specifications for electronics factories are equilateral triangles in color, yellow in color, and black on a black background. It is used in hazardous waste storage facilities, including houses, some hazardous waste utilization, disposal sites, etc. The back of the main logo is fixed with screws, and the lower edge of the sign is 120cm from the ground.

Used in hazardous waste storage facilities, including but not limited to fences, storage facilities, warehouses, etc.

There are three main types of hazardous waste in electronics factories: first, hazardous substances, such as cadmium, lead, chromium and other heavy metals; second, organic matter, such as solvents, paints, glues, etc.; The third is hazardous waste electronic products, such as waste computers, mobile phones, televisions, etc. These wastes are very harmful to the environment and the human body, such as causing pollution and disease.

In order to reduce these hazards, electronics factories need to take strict hygiene measures, properly dispose of waste, implement classified management, classified treatment and classified disposal, control the discharge and treatment of waste, and ensure that there is no impact on the environment and human body.

Hazardous waste from electronics factories includes waste batteries, waste electronic components, waste PCB boards, waste circuit boards, etc. These items contain toxic and harmful substances, such as lead, mercury, cadmium, arsenic, etc., which pose a threat to the environment and human health. These wastes need to be properly treated and disposed of to reduce environmental impact and harm.

Establish a sound waste management system, strengthen the supervision and management of waste classification, storage, transportation, disposal and other links, and minimize the discharge of hazardous waste. At the same time, it is recommended that enterprises improve production processes and products, reduce the amount of waste generated, and achieve the goal of environmental protection and sustainable development.
