Solid waste turned waste into treasure "secondary resources valley" built in Yunnan

The China's "secondary resources valley", which aims to turn environmental solid waste into useful resources, was announced here. It marks that China has embarked on an industrialized development path in solving environmental pollution and resource shortages.

With economic and social development, environmental pollution and shortage of resources have become an issue of increasing concern throughout the world. In recent years, many developed countries have listed waste resource recycling as the key to national economic construction and set off a climax of the "secondary resources industrial revolution." China also paid great attention to the recycling of resources. In 1997, the state approved the approval of the state and Yunnan Province invested 56 million yuan. Based on the Institute of Waste Recycling of Kunming University of Science and Technology, it began to create China's only solid waste. The National Engineering Research Center for Recycling Resources is used to promote the transformation of research results in the field of waste resource recycling to the direction of industrialization, and to establish and develop a new modern industrial system, the renewable resources industry.

Over the past few years, during the construction process, the National Engineering Research Center has devoted itself to the application foundation, engineering, and industrialization of the cross-disciplinary fields of environmental engineering and materials engineering, and pioneered the theory of turning solid waste into new resources. And technology, developed common technologies and key technologies to meet the needs of large-scale production, and continuously applied new materials, new processes, new products, and new equipment that are mature in research to various related industries.

At present, at this engineering center known as the “secondary resource valley” in China, people were pleasantly surprised to find that discarded plastic waste, waste rubber, industrial waste, etc., have become manhole covers, flower bed railings, building templates, and rubber joints. Bowls and other polymer-based waste composite new materials. Here, solidifyable and hard industrial wastes are made into silicate-based materials, and are then used as wall materials such as load-bearing bricks, hollow bricks, floor tiles, and artificial stones, while other industrial wastes and waste glass are manufactured. Glass-based materials, used as insulation, sound insulation, anti-corrosion, fire protection materials. Waste aluminum cans and used glass discarded by people are usually combined into metal-based waste composite materials, and various types of profiles such as idler rollers, bearing seats, and seamless pipes of belt conveyors are manufactured.

After several years of hard work, this engineering center has formed a high-level research and development team and established a cooperation network with a group of famous institutions of higher learning, scientific research institutes, and enterprise groups. It has established partnerships with Shanghai, Jiangsu, and Fujian provinces and cities. Technology transfer has been carried out and is being continuously promoted throughout the country.

Experts here pointed out that the raw materials of waste composite materials are all waste, and the raw materials are stable for a long time and their prices are low. Therefore, they have greater social, environmental, economic benefits and obvious competitive advantages.

It is reported that the Engineering Center will also establish 20 to 30 industrial composite bases for waste composites throughout the country, making the engineering center a technological source that collects and selects upstream scientific research results, and focuses on the integration of scientific research achievements into engineering systems and engineering. The spread of technology to downstream businesses.
