China has made remarkable progress in developing a circular economy, which is evident to all. In 2003, energy consumption per 10,000 yuan of GDP had dropped by 50% compared to 1990. The reuse rate of industrial water increased by approximately 15%, and the comprehensive utilization rate of industrial solid waste reached 55.8%. Specifically, the utilization rate of fly ash rose from 38% in 1990 to 56% in 2003. Over 60 million tons of waste materials, such as chemical and paper products, were recovered during that time. Additionally, pilot projects for circular economy in Liaoning and Guiyang have shown steady progress.
However, at the recent China Nuclear Economy Development Forum held at the 9th Beijing Science Fair, many Chinese and international experts highlighted several challenges in China's circular economy development. Experts like Qian Yi, deputy director of the National People’s Congress’ Environment and Resources Commission, and Shao Xuemin, representative of the United Nations Environmental Programme in China, emphasized that these issues are hindering the full potential of China’s circular economy.
After analyzing these problems, experts from the Macroeconomic Research Institute of the National Development and Reform Commission identified five key challenges:
First, there is a lack of public understanding of the circular economy. Under the pressure of pursuing GDP growth, some local officials and departments ignore the contradictions between economic expansion and resource and environmental constraints. Some people still believe that maintaining a 9% annual growth rate is more important than sustainability. Others focus only on individual enterprises rather than the multi-level nature of the circular economy. Local governments often prioritize GDP-driven performance, leading to continued emphasis on traditional economic growth models despite national commitments to sustainable development.
Second, the legal and regulatory framework for promoting the circular economy is still underdeveloped. Although China has enacted laws like the "Cleaner Production Promotion Law" and the "Environmental Impact Assessment Law," they fall short of the requirements for a comprehensive circular economy system. Existing regulations often lack clear guidance, specific provisions, and enforcement mechanisms, making it difficult to hold violators accountable.
Third, there is a shortage of technological innovation and application in support of the circular economy. China lags behind developed countries by 15–20 years in overall science and technology. Only 15% of key technologies and equipment match international standards, while two-thirds are considered outdated or basic.
Fourth, there is no unified national strategy or implementation plan to guide circular economy development. As a strategic choice for achieving a well-off society, the circular economy requires coordinated efforts from all levels of government and clear division of responsibilities among relevant departments.
Lastly, there is no comprehensive indicator or evaluation system tailored to China’s conditions. While some provinces and cities are experimenting with circular economy planning, the theoretical framework and evaluation methods remain underdeveloped.
These challenges highlight the need for stronger policy support, improved legislation, technological advancement, and better coordination across sectors to fully realize the potential of a sustainable circular economy in China.
New Energy Cast Film Line
Renewable Energy Advances with Cast Film Lines
As the energy industry leans more towards renewable resources, solar energy emerges as a prominent option. Here is where "New Energy Cast Film Lines" play a critical role. They produce the specialized films used in solar technology, which are key in tapping into the sun's power.
The Importance of Plastic Films in Solar Systems
Solar setups often depend on plastic films. These essential components are made using machinery like the "Solar Energy Cast Film Machine" and the "Photovoltaic Cast Film Machine." The films created have unique characteristics, allowing them to turn solar energy into electrical power.
Let's take a closer look at two main film types
Photovoltaic Films: Found in the heart of solar cells, these films, primarily silicon-based, absorb sunlight and generate power thanks to the photovoltaic effect.
Backsheet Films: Acting as a shield, these films are placed on the rear of solar panels to protect against weathering, helping to ensure the panels' efficacy over time.
The Process Behind New Energy Cast Film Lines
Machines involved in this process, which include the indispensable "Plastic Film Perforation Machine," perform a procedure known as cast film extrusion. This involves melting plastic, shaping it into sheets that are then cooled, set, and rolled. These machines are carefully calibrated to output films with precise attributes suited to the solar energy industry.
Choosing Suitable Cast Film Line Equipment
Selecting a "New Energy Cast Film Line" requires a few considerations:
Material Choice: The type of plastic you use has implications for the film's overall performance and lifespan.
Quality of Film: Details like film thickness, light permeability, and strength need to be in tune with the intended solar applications.
Custom Features: Features such as film perforations can be added to enhance the functionality of the films, such as enabling the breathability of backsheet films to reduce moisture buildup.
Embracing a Green Energy Future
With "New Energy Cast Film Lines," we're not just investing in equipment. We're taking strides towards a greener, more sustainable energy landscape by producing essential components for solar technology, furthering the progress in the realm of renewable energy.
