To address the need of transformative products in China’s wood industry, led by Prof. Yu Wenji, the research team from the Research Institute of Wood Industry, Chinese Academy of Forestry, has proposed a multiscale recombinant preparation technology system for green low-carbon materials. The team achieved a breakthrough in the key technology of continuous one-step forming of large-scale recombinant units, establishing microscale internal interfaces in the glulam, meso-scale fiber-veneer interfaces, and a mesoscopic fiber layering interface system. They invented manufacturing equipment for continuous production of multiscale recombinant units, enabling the efficient use of small and low-quality materials. The comprehensive utilization rate of raw materials reached 90%, labor efficiency increased by over 10 times, and energy consumption decreased by 20%. This technology has become an advanced alternative for traditional composite wood panels, finding widespread applications in architectural structures, landscaping, and home furnishings.

Demonstration bases for high-performance recombinant wood and high-strength oriented strand board have been established in cities such as Laibin in Guangxi, Pizhou in Jiangsu, and Anfu in Jiangxi. These bases provides technical support for the large-scale continuous manufacturing of recombinant wood materials and the efficient utilization of wood and bamboo, promoting the development of green low-carbon building materials and establishing China as a leading force in the field of recombinant materials.
