In coastal areas, how to deal with marine garbage has always been a headache. In Qifeng Village, Fenghua, Ningbo, Zhejiang, the local area has recycled more than 1,000 tons of various marine garbage in a year through a complete set of processes such as recycling, sorting and processing with intelligent environmental protection facilities. Taking the initiative to clean up marine garbage has become a "new habit" for local fishermen.

Next to the "Ocean Partner" environmental protection cabin in Qifeng Village, Fenghua District, Ningbo, Zhejiang, villager Chen Fei is operating skillfully on the screen of the environmental protection cabin. As the cabin door opens, he throws in the old fishing nets, plastic bottles, etc. that he has sorted and collected recently.

Chen Fei's "new habit" has to start with the "big guy" in front of him. In July last year, Zhejiang's first village-level carbon credit "Ocean Partner" environmental protection cabin project was put into use in Qifeng Village on a pilot basis. The environmental protection cabin, which covers an area of more than 600 square meters, is built with several abandoned containers and is equipped with an intelligent recycling and storage cabin for marine waste. Fishermen will get corresponding "carbon credits" after throwing in old fish baskets, broken fishing nets, broken buoys, etc., which can be exchanged for daily necessities.

In addition, the village has set up an intelligent resource recycling station for the collection, treatment and transportation of marine waste, which has recycled more than 1,000 tons of marine waste. The recycled marine waste is finally recycled and processed uniformly, and after melting, filtering, cutting and other links, it is transformed into recycled plastic particles of uniform size.

It is understood that the local area encourages villagers to collect marine plastic waste to increase income through the recycling and processing of marine waste, and has achieved a total of 1.5 million yuan in benefits to fishermen and farmers in one year.

Chongqing: Improving resource utilization, scrapped equipment is "reborn"

In order to accelerate the comprehensive green transformation of economic and social development, various places have been working hard to improve resource utilization efficiency and increase the recycling and utilization rate of scrapped equipment. In Chongqing, some scrapped materials with high environmental risks and high disposal costs have gradually been turned into treasures and recycled.

At the Electric Power Renewable Resources Recycling Center in Chongqing Yongchuan Gangqiao Industrial Park, scrapped transformers are sent to the dismantling workshop. After multiple processes such as hoisting, removing the cover, filtering the oil, and dismantling, they become various high-value renewable resources such as silicon steel and copper. These renewable resources will be melted and formed by the downstream industrial chain or used comprehensively after secondary processing.

Liao Huiying, head of the Materials Department of State Grid Chongqing Electric Power Company, said: "In the past, scrapped power equipment was auctioned as a whole. After purchase, recyclers often simply dismantled it in a small workshop. The dismantling operation efficiency was low, and it was difficult to effectively prevent the risk of environmental pollution such as transformer oil. At the same time, there are also difficulties in supervision in the subsequent disposal and flow."

At present, the local scrapped power equipment is dismantled in a centralized and refined manner and transformed into various renewable resources. From waste to products, a complete and scientific scrap material disposal chain has been formed.

Wind power clusters and birds coexist harmoniously under the same blue sky

In Yancheng, Jiangsu, there is an ecological restoration wetland known as the "International Airport" for migratory birds, which welcomes millions of migratory birds to transit and rest every year. China's largest offshore wind power cluster is also located in Yancheng, Jiangsu. So how do wind power facilities coexist with birds under the same blue sky? How does offshore wind power protect the results of ecological restoration? Let's take a look.

In recent days, a large number of migratory birds of the genus waders have arrived at the Tiaozini Wetland in Yancheng, Jiangsu. They forage for food, rest, and molt in the vast tidal wetlands. In the high tide habitats artificially built for migratory birds, thousands of birds gather into "bird waves", which is a spectacular scene. Li Dongming is a staff member of the reserve. His job is to take pictures of the migratory birds coming and going and record their numbers.

As migratory birds arrive one after another, nearby wind power companies that have been accompanying these birds all year round are also busy. Migratory birds will use different meteorological conditions, such as wind direction and wind speed, to improve flight efficiency, so the places where migratory birds like to gather are also suitable for wind power installation. In the past few days, the staff on duty 24 hours a day in the central control hall of many nearby wind farms have a new identity-migratory bird observer.

In order to protect the migratory bird flight channel, these wind turbines along the coast of Yancheng have also been specially painted, and the staff called them "lipstick on the wind turbines".

Ma Yuqing, director of the Dongtai offshore wind farm in Yancheng, Jiangsu, said: "In order to prevent birds from hitting wind turbines during migration, we set a striking red warning color on the tip of the wind turbine blades, which can greatly reduce the risk of birds hitting wind turbines. We hope that through the efforts of each of us, we can achieve harmonious coexistence between man and nature."

Cultivating intelligent experts and using AI technology for ecological restoration

At present, the area of restoration and management of important ecosystems in China exceeds 100 million mu, and there are many ways to restore the ecology. So, what new technologies will be used in ecological restoration in the future? Let's find out together.

The system we are seeing now is the industry model in the field of ecological environment that China National Environmental Monitoring Center is building. It uses AI technology and will generate an intelligent expert in the field of ecological restoration in the future.

Tang Qiaoling, an architect of Baidu Intelligent Cloud Solutions, introduced: "In building an industry model in the field of ecological environment, we have also collected monitoring data, policy standards, and some technical specifications of the ecological environment, and unified them with the big model for learning and training to form a series of intelligent entities in the field of ecological environment, which is what we call intelligent experts."

Through intelligent experts, on-site staff can quickly query and analyze data on the local ecological environment, find the most suitable ecological restoration method, and then help staff make some decisions, which can quickly improve the regulatory capabilities in the field of ecological environment. With the development of big models, the demand for computing power by intelligent experts is getting higher and higher. For this reason, China National Environmental Monitoring Center has built a computer room to provide computing power for this system.

It is reported that the staff will gradually establish a knowledge base in the field of ecological environment and a case library of industry expert experience, and hand it over to the big model for learning and training to cultivate it into an intelligent expert. This big model will also start internal testing in October this year and will be officially put into use at the end of November.
