From October 17 – 19, the first birthday of the journal was celebrated with a conference to which over 100 scientists attended.

Signing ceremony of the Qingdao Synthetic Biology Technology Innovation Strategic Alliance

T the conference theme was “Innovation of green and low-carbon technology, empowering carbon peak and carbon neutrality”, focusing on carbon resources, low-carbon conversion technology, multi-energy integration and utilization and other fields for in-depth discussions. The conference invited more than 100 experts, scholars, and business people to attend the conference.

As the chairman of this conference, QIBEBT director and Green Carbon editor-in-chief Lv Xuefeng said that this conference aims to build a high-level exchange platform for scientific research in the field of green and low-carbon research across the country. Breakthroughs will be sought in perovskite photovoltaics, solid-state lithium batteries, biosynthesis of energetic materials, green bio-jet fuel, new generation of bio-based green plasticizers, and iron-branched butyl-pentane rubber. In order to further expand China’s academic influence in the field of green and low-carbon science and technology, the international academic journal Green Carbon aims to promote scientific and technological innovation in the field of sustainable development and provide a high-quality and open academic exchange platform for global researchers in the field of green and low-carbon.

At the meeting, the “Qingdao Synthetic Biology Technology Innovation Strategic Alliance” jointly established by the Qingdao Institute of Energy and relevant enterprises, universities and research institutes was formally established. Qingdao Wanyuan Environmental Technology Co., Ltd., Shandong Jinzhirui New Materials Development Co., Ltd., Shandong Environmental Protection Development Group Co., Ltd., Qingdao Zhongchuanghuike Biotechnology Co., Ltd., Qingdao Zhongke Green Carbon Technology Co., Ltd., Shandong Hengxin Group Co., Ltd., Qingdao Zhongke Yuanben New Energy Co., Ltd., and China Hydrogen Energy Company (Energy Cube (Qingdao) Data Technology Co., Ltd.) signed contracts with the Institute respectively.

The conference also held a special event for the first anniversary of the publication of the international journal Green Carbon. Jiang Lei and Lv Xuefeng presented the “Excellent Editorial Board Award” to Rolf Schmid, Tang Yong, Chen Xuesi and Lv Xuefeng presented the “Excellent Young Editorial Board Award” to 24 young editors, and Rolf Schmid and Lv Xuefeng jointly unveiled the Green Carbon Overseas (Germany) Office.

Launch of a mobile deep-sea aquaculture vessel in Qingdao

http://en.people.cn/n3/2025/0418/c90000-20304151.html

A 150,000-tonne deep-sea intelligent aquaculture vessel was delivered for use in Qingdao. The ship is 244.9 meters long and houses 15 breeding cabins with a total water holding capacity of nearly 100,000 cubic meters.

The ship-borne smart aquaculture system is expected to have an annual output of 3,600 tonnes of high-quality fish. The breeding cabins can be used to cultivate fish species such as large yellow croaker and salmon.

The new aquaculture vessel is an updated version of its 100,000-tonne predecessor delivered in 2022. Its predecessor has now already traveled over 17,000 nautical miles. The vessel pushed the aquaculture area from nearshore to deep sea, using high-quality seawater resources for breeding.

QIBEBT-led consortium achieves bacterial degradation of PET bottles to provide terephtalic acid in 97% yield

A research team from the Qingdao Institute of Bioenergy and Bioprocess Technology of the Chinese Academy of Sciences, in collaboration with Nanjing Tech University and Greifswald University, has introduced an innovative solution for the depolymerization of polyethylene terephthalate (PET). This solution utilizes an engineered whole-cell biocatalyst based on the thermophilic bacterium Clostridium thermocellum.

This study builds on prior work, where the research team first demonstrated the concept of whole-cell catalytic PET depolymerization. In that study, the genetically engineered C. thermocellum expressed leaf compost cutinase (LCC) via a plasmid for high-temperature PET depolymerization.

In this study, the researchers integrated LCC directly into the chromosome of C. thermocellum, ensuring stable enzyme expression. They further enhanced the system by introducing LCC variants and co-expressing hydrophobic modules.

By optimizing reaction conditions and controlling pH, the researchers achieved a significant improvement in PET depolymerization efficiency with minimal accumulation of the intermediate product mono(2-hydroxyethyl) terephthalate (MHET).

When tested with pretreated PET bottle particles, about 97% of the added PET was converted into terephthalic acid (TPA), a key monomer used in producing new plastics or high-value chemicals. This high level of performance positions the system as a promising green solution for PET recycling.

Additionally, C. thermocellum is naturally capable of degrading cellulose, making it a potential candidate for directly processing mixed textile waste that contains cotton fibers and PET.

An exosceleton for mounting climbing tested at Taishan mountain, Qingdao

During the Chinese New Year holiday, a mountain climbing support robot jointly developed by Taishan Wenlun Group and Shenzhen Kenqi Technology Co. was test-introduced in the Taishan Scenic Area. Guangming reported.

According to Taishan Wenlun Group, the mountain climbing support robot can be used in a wide range of areas in daily life and work, such as mountain climbing, fitness, running, walking, and climbing up and down stairs. It weighs just 1.8 kilograms and is ergonomically designed with power, electronics and artificial intelligence (AI) algorithms. It can sense every movement of the lower limbs and provide support at the right time.

According to the group, it can operate continuously for more than five hours. The product is currently in the trial operation phase, and the company plans to launch 200 units on the market in early March.
