Green development is an all-round and revolutionary change in production methods, lifestyles, ways of thinking and values. Make the living environment "beautiful", make the industrial structure "light", and make the development model "green". In today's China, new energy and new technologies continue to stimulate new kinetic energy.
As small as a company or as large as a place, when environmental investment is no longer an "external cost", energy saving and low carbon are the most "economical" choices. Next, go to the bank of the Yangtze River to see the exploration of turning chemical waste from "gray" to "green".
Yichang TV reporter Han Jingwen: This is a small ecological park on the bank of the Yangtze River in Yichang, Hubei. In this park, whether it is the footpath or the flower beds on both sides, it is made of waste phosphorus produced by chemical plants. Made of plaster. In the five provinces of Hubei, Yunnan, Guizhou, Sichuan, and Anhui in the Yangtze River Economic Belt, 80% of my country's phosphorus chemical enterprises are concentrated. The waste phosphogypsum produced by these enterprises is a "big problem" in the ecological and environmental protection of the Yangtze River.
How to turn chemical waste into valuables and useful resources? Through years of continuous technical research, the enterprises along the river have finally solved the key technical difficulties and achieved a series of application breakthroughs.
In the Phosphogypsum Comprehensive Utilization Center of Hubei Three Gorges Laboratory, the garden between the buildings is lined with green trees and flowers are in full bloom, and the soil for planting these plants is harmless and improved phosphogypsum.
Cao Bensanlang, Research Assistant of the Phosphogypsum Utilization R&D Center of Hubei Three Gorges Laboratory: Through composting, plant straw and animal manure are naturally fermented under the action of microorganisms, and then planting plants and introducing earthworms and other animals to make phosphorus Gypsum becomes real soil.
