China Classification Society Quality Certification Co., Ltd. (CCSC) and Guangdong Yuezhu Technology Co., Ltd. jointly developed the worlds first all-bamboo zero-carbon (steel connection) container. Recently, it successfully completed all the inspection work and officially obtained the inspection certificate of China Classification Society. It will soon be put into the first transportation display, marking a major technological breakthrough in the field of green and low-carbon logistics equipment in China.
Under the guidance of the "double carbon" goal, bamboo, as a renewable, low-carbon and fast-growing natural resource, is gradually moving from traditional building materials to high-end industrial applications. The whole bamboo zero-carbon (steel connection) container replaces steel with bamboo, replacing steel by more than 60%. A single 666.66cm standard container can reduce carbon emissions by 2.68 tons. It is a real green logistics equipment with low carbon, light weight, high strength and environmental protection.
The product gives full play to the advantages of bamboo light weight, high strength, excellent tensile and bending performance, outstanding carbon fixation capacity, combined with the structural design of steel connectors, to fully meet the key performance indicators of the container in terms of structural strength, durability, compression and bending resistance. By the strict control of China Classification Society, the product has reached the standard of traditional steel container in terms of structural strength and safety performance.
The project actively responds to President Xi Jinpings promotion of the implementation of the global development initiative: accelerating the green and low-carbon transformation and realizing green recovery and development. China will strive to achieve carbon peak by 2030 and carbon neutrality by 2060. China will vigorously support the green and low-carbon development of energy in developing countries, the national "Tenth Five-Year Plan", the "14th Five-Year Plan for Forestry and Grassland Protection and Development" and the "Action Plan for Promoting the Production and Application of Green Building Materials" and other policy calls to promote Efficient use of bamboo resources will help rural revitalization and the development of green building materials. The R & D team is composed of inspection institutions, universities, scientific research institutes and enterprises, forming a collaborative innovation model of the integration of production, education, research and application.
CCSC is deeply involved in the product design phase from the beginning of the project. In view of the technical problems such as anisotropy of bamboo, dry shrinkage and wet expansion, node connection, CCSC joint research and development team carried out multi-round structural optimization and material selection demonstration, and innovatively proposed the "bamboo-steel cooperative stress" structural system to ensure that the container has excellent bending, compression, shear and seismic performance while being lightweight.
In the trial production stage, CCSC led the development of a special inspection plan for all bamboo containers, covering the whole process quality control of raw material screening, bamboo chip treatment, gluing and pressing, finishing and molding, etc. In view of the different failure modes of bamboo and steel, CCSC for the first time incorporated low-cycle repeated loading test, node connection performance test, beam-column axial compression and bending synergy test into the inspection system, which comprehensively verified the reliability of the product under long-term use, extreme load and fatigue conditions. The test data show that under the premise of replacing more than 60% of steel, the safety factor of the whole bamboo container structure meets the requirements of the International Container Safety Convention (CSC), and the bending, compression and fatigue resistance all reach the level of traditional steel containers.
Based on the above innovative achievements, CCSC has simultaneously started the green evaluation of the carbon footprint of bamboo zero-carbon containers, and actively promoted the establishment of bamboo container product standards, and gradually formed a technical support system covering the whole chain of design, manufacturing, inspection and use.
At present, the first all-bamboo zero-carbon container has the conditions for display and transportation, and the first transportation display activity will be launched with the support of CCSC. In the follow-up, CCSC will jointly hold a launching ceremony with all parties of the project to show the inspection and test results on site.
The successful development of the whole bamboo zero-carbon container is not only an important breakthrough in the field of green equipment manufacturing in China, but also a "Chinese plan" for the global logistics industry to achieve low-carbon transformation ". CCSC will continue to play the technical leading role of inspection institutions, promote the safe, standardized and efficient application of bamboo in modern logistics equipment, and join hands with all parties to build a green, circular and low-carbon future logistics system.
