What Are the Different Types of Green Technology Products?
Green technology refers to a technology system that can reduce pollution, reduce consumption, and improve ecology. Green technology is a dynamic system composed of relevant knowledge, capabilities and material means.
Green technology
- Environmental scientists, ecological scientists, and related technical experts are carriers of knowledge, [1]
- The so-called "green technology" simply refers to a technology in which people can make full use of natural resources and are harmless to the environment in production and use. The important contribution of green technology to environmental protection has made green technology grow gradually with the rise of the global environmental protection cause.
- Green technology is also called environmentally friendly technology or ecological technology. The social ecological movement that originated in the western industrialized countries in the 1970s refers to a general term for technologies, processes or products that reduce environmental pollution and reduce the use of raw materials, natural resources and energy. The emergence of this concept originates from the reflection on the situation that modern technology destroys the ecological environment and threatens the survival of human beings. It can be considered as one of the signs of ecological philosophy, ecological culture and even ecological civilization.
- From the perspective of the industrial community, green technologies can be divided into two categories, assistive technologies and core technologies. The role of green technologies in the industrial community is mainly reflected in two aspects: one is the transformation and innovation of auxiliary green technologies on the production process in the industrial field, and the other is the impact of core green technologies on the final products in the industrial field. The final result of its role is to continuously promote the evolution of the industry through its application and promotion in the industrial field.
- The development of green technology has gone through a long history and is an inevitable trend in the development of science and technology. The concept of green technology was formally introduced in the 1990s. Objectively speaking, it was the pollution incidents and environmental issues that made scientists realize the importance of green technology. In order to solve environmental problems, human beings need more advanced technology to seek a new technical system to achieve sustainable human development. In this context, green technology came into being.
- Since the 1940s, a series of pollution incidents caused by water and air pollution have occurred in developed countries.
- The economic value of green technology includes three parts:
- press
- Green technology carries a new type of human-nature relationship, emphasizing the prevention and control of environmental pollution and maintaining the natural ecological balance. In the 21st century, where science and technology are advancing rapidly, with the environmental pollution and ecological deterioration, the idea that man is the master of nature and that "people are better than heaven" has not been supported by most people. People are the constituent elements of the biosphere, and there is an asymmetrical interactive relationship between people and nature. No matter how big the role of human beings is, human influence on nature only changes the specific evolution of nature. It is impossible to destroy nature, and even less to eliminate its existence. However, the tremendous reaction of nature to human beings may destroy human beings and eliminate their existence. Even if all the nuclear installations in the world explode at the same time, it is humans, not the earth, that is destroyed. Therefore, in the highest sense, nature is the master of man, and man can only respect and fear nature. Nature is the living environment of human beings, and any human influence on nature will eventually be transformed into human influence. Environmental pollution and ecological degradation are only relative to people. Without people, pollution and ecological degradation do not matter in nature.
- Man is the product of the evolution of living things over hundreds of millions of years. It is the way the earth has evolved since the Cambrian that has created life and made man. Due to human physiological characteristics, people can only adapt to the evolution or existence of the earth at this stage, but cannot adapt to other evolution or existence of the earth (such as no oxygen, no water). Therefore, human activities should not change the basic evolution of the earth at this stage, otherwise, the change of the basic evolution of the earth will bring disaster to humankind.
- Modern technology featuring high consumption, high emissions, and easy pollution, pursues "
- In the "China's Cross-century Green Engineering Plan" formulated in 1996, China's environmental protection priorities were identified: coal, oil and gas, electricity, metallurgy, non-ferrous metals, building materials, chemicals, textiles and medicine. Pollutant emissions from these industries account for more than 90% of China's industrial pollutant emissions. Correspondingly, the main contents of China's development of green technologies are: energy technology, materials technology, catalyst technology, separation technology, biotechnology, resource recovery and utilization technology.
- China is rich in energy, but its geographical distribution is uneven, coal is the main energy structure, and energy shortages and waste coexist. Clean coal technology is one of the more successful green technologies developed in China. China vigorously promotes less-polluting mining and coal liquefaction and vaporization technologies. Material technologies for the purpose of improving the environment, saving energy, saving the amount of materials used, and reducing the types of materials used have also developed well. China has introduced and independently developed new green materials, such as: degradable plastics, nanomaterials, special ceramics, smart materials, engineering plastics, and green building materials. They have been developed and applied to varying degrees. The successful development and application of biotechnology in agriculture are mainly the application of genetic engineering and molecular biology in breeding and the combination of information technology and conventional breeding technology as the main ways to cultivate super cassava, super rice, short-season disease-resistant potatoes, Special corn and disease-resistant wheat are the representative technologies. By 2008, China had obtained more than 100 kinds of transgenic plants, and achieved many world-leading results in this regard. For example, transgenic tobacco resistant to mosaic virus and transgenic cotton resistant to cotton bollworm. Agro-ecological engineering is a new green technology based on biotechnology and combining multiple technologies that has emerged in China in the early 21st century. It has also developed very successfully.
