Construction of Electronic Waste Environmental Protection Concept

5/23/2018

The problem of electronic waste has gradually become a serious environmental problem. The construction of an environmental protection concept platform. The harmfulness of electronic waste. Harmfulness, the construction of the concept of environmental protection for electronic waste in China.

1, With the rapid development of electronic and high-tech industries and the rapid upgrading of electronic products, the problem of electronic waste has gradually become a serious environmental problem. China has also gradually realized that the traditional economy with the primary goal of simply pursuing GDP has brought about a series of insurmountable social abuses. Environmental pollution and resource destruction are the most prominent manifestations. The industrial sector has gradually realized that it is not worth the proceeds of its own economic recovery that the production and operation of the company is always at the expense of the environment. Countries are actively promoting circular economy and clean production, reducing material consumption and energy consumption, reducing pollutant emissions, and taking the road of circular economy development. At present, China's environmental management of electronic waste is basically still in its infancy. It not only needs corresponding policies and regulations, specialized agencies, unified management, safe and effective technologies and equipment to manage it, but also must promote e-waste. The concept of resource recycling and environmental protection is deeply rooted in people's minds. This is the fundamental way to solve the problem of electronic waste.

2, Electronic waste, commonly known as e-waste, is a generic name for electronic products that are at or near their "life cycle" priorities, as well as precision electronic equipment that some enterprises and institutions have eliminated. According to the relevant report of the European Union in 2005, electronic waste has increased by 16% to 28% every five years, which is three times faster than the growth of total waste. It is the fastest growing garbage in the world. E-waste is not only diverse, but also has complex components. Most of them contain toxic and hazardous substances. If handled improperly, it will cause great harm to the environment and the human body.

(1) The harm of electronic waste to the environment
According to the source, electronic waste can be divided into two categories: waste generated during the production of electronic and electrical products and electronic and electrical equipment that are discarded after reaching the end of their useful life. These wastes are different from ordinary urban wastes, and their manufacturing materials are complex. Some household electrical appliances also contain chemical substances. If they are not properly disposed and landfilled directly, they will cause environmental pollution. For example, refrigerators and foaming agents in refrigerators are the culprits of the destruction of the ozone layer. The tubes for computers and televisions are explosive wastes. They also contain 2 Kg to 4 Kg of lead, and fluorescent screens contain mercury waste. Various circuits Tin, lead, polyvinyl chloride, mercury and other toxic substances in the plate easily leach out of the leachate and contaminate soil and groundwater. When the rain comes into contact with these buried garbage, it causes a chemical reaction and forms a “liquor leachate” that is more toxic. Even if the bottom and top of the landfill are sealed, leakage or continuous pollution may result from damage or erosion of the sealed fiber tape and welding interface due to land subsidence and geological changes. If the incineration method is used, the burned electronic waste will release a variety of highly toxic gases such as CO, HC, and NOX, which will form highly irritating photochemical smog under the action of sunlight. Incineration also releases a large number of particles that affect the climate, reduce visibility, release mercury vapor, and are extremely toxic to the central nervous system.

(2) The impact of electronic waste on human health
A large number of electronic appliances bring convenience to people's lives and work, and the toxic substances in them endanger human health. If more than 50% of the materials in the computer are harmful to the human body: the display contains harmful substances such as lead, cadmium, mercury, hexavalent chromium, polyvinyl chloride plastics, and brominated flame retardants; the cathode lead (CRT) has a lead content of 27% The iron chassis contains cadmium; the switch and position sensor contains mercury; the printed circuit board contains antimony and brominated flame retardants; the wires and old packaging contain polyvinyl chloride, chips, and disk drives containing mercury and chromium. They can cause various degrees of damage to human organs and tissues, cause carcinogenic or teratogenic, mutagenic substances, most of them can damage the brain and spinal cord, kidneys, nerves, etc., and the rest can weaken the body or damage the shape.

3, The solution of the e-waste problem requires all countries to carry out research from the strategic management level, establish a corresponding strategic alliance, follow a certain operating mechanism, and prevent and control e-waste pollution from a global scale. China is in the process of formulating increasingly strict environmental protection laws and economic policies that are conducive to environmental protection, to guide and restrict the business community, consumers, and society as a whole to reduce the emission of pollutants, protect and improve the quality of the environment, and change the general principle requirements. For specific quantitative indicators. To arouse the whole society to enhance environmental awareness, support environmental protection, participate in green changes, build ecological civilization, and practice environmental protection concepts.

(1) Disposal of electronic waste based on public participation
The responsibility of the public is to restrain products from becoming waste, to recycle as much as possible, and to properly dispose of electronic waste. Master's thesis, hazardous. Of course, this is more the disposal of the civil subject of his own articles. If there is no prohibitive provision of the forcible law, the people have the freedom to dispose of their financial affairs. Master's thesis, hazardous. The electronic waste environmental protection organization NGO (NGO) is an important part of public participation. The establishment and development of environmental protection NGOs is a good form of organization and an effective way to protect the environment. It is also a concrete measure for public participation in environmental protection. which performed. The civil society organization is the social foundation and the people's power to protect the environment. Its activities are conducive to the development of environmental protection. Environmental protection NGOs and mass movements are an effective form of public participation in environmental management. Their activities help the government to strengthen environmental management. The activities of environmental protection NGOs are conducive to raising the awareness of environmental protection in the entire society and promoting the formation of environmental ethics. Specific to e-waste, the public, such as producers, sellers, and consumers, all participate in the management and control of e-waste pollution.

(2) Governance of electronic waste pollution through integrated decision-making on environment and development
The mistakes of traditional decision-making call for decision-making, the new situation of sustainable development, and new tasks give rise to comprehensive decision-making. Comprehensive decision-making on the environment and development is a policy approach that fundamentally solves environmental problems. Pursuing the maximization of comprehensive social, economic, and environmental benefits, adhering to the appropriate decision-making costs, controlling pollution at the source, and fully embodying scientificity, sustainability, and democracy are the basic principles that should be followed in the overall decision-making of the environment and development. Strengthen the mechanism construction and capacity building for comprehensive decision-making on environment and development, integrate comprehensive environmental and development decision-making into legalization, institutionalize and standardize the environment and develop comprehensive decision-making behavior, strengthen macro-environmental management, and improve comprehensive decision-making capabilities. The best way to manage e-waste is to closely combine the development of electronic technology and environmental governance, promote mutual development, and form an electronic waste management mechanism that promotes the development of the meridian industry in the entire society.
