To further drive innovation-led development and strengthen industry-university-research collaboration, Lin Xiaojian, Sales Director of Solid Waste at Hongfa Heavy Industry, led a team to the Solid Waste Research Center at Guilin University of Technology for an exchange and learning visit. The team engaged in in-depth discussions with Professor Jing Daiyan, Teacher Xiang Weiheng, and Teacher Hu Cheng from the School of Materials Science and Engineering, jointly exploring solid waste treatment applications and technologies.

Solid waste recycling is a key ecological and environmental protection initiative promoted in recent years. Guilin University of Technology has established an Engineering Research Center for Solid Waste Recycling, backed by three major research platforms: the "Guangxi Engineering and Technology Research Center for Industrial Slag Building Material Resource Utilization" (a major sci-tech innovation base under the Guangxi Department of Science and Technology), the "Guangxi Beibu Gulf Green Marine Engineering Materials Engineering Research Center" (under the Guangxi Development and Reform Commission), and the "Guangxi Key Laboratory of Building New Energy and Energy Conservation." These platforms provide extensive practical experience and robust technical support in solid waste research.

Guided by Teacher Hu Cheng, the Hongfa delegation toured the university's research milestones in solid waste management. The university has won numerous sci-tech innovation awards and achieved remarkable success in this field, offering valuable lessons for Hongfa Heavy Industry. Both parties expressed their hope to achieve mutual benefit and win-win outcomes through university-enterprise cooperation, translating solid waste recycling into tangible results. Together, they aim to continuously improve the utilization rate of industrial solid waste and construction debris, promote energy conservation and emission reduction, and build beautiful, green, and eco-friendly cities.

With 30 years of deep expertise in building material equipment and the R&D and production of new green wall materials, Hongfa Heavy Industry has extensive experience in processing solid waste into recycled green building materials. Hongfa's five complete sets of new wall material equipment—including AAC block and panel production lines, lightweight composite wall panel production lines, fully automatic block making machines, concrete batching plants, and large-tonnage hydraulic presses—can recycle bulk industrial solid wastes such as coal gangue, steel slag, furnace slag, tailings, construction debris, and fly ash. The equipment produces autoclaved aerated concrete (AAC) blocks and panels, sponge city permeable bricks, retaining bricks, hydraulic bricks, slope protection bricks, landscaping bricks, and faux stone PC bricks. With advantages of low cost, wide applicability, and green low-carbon footprint, these products have become a primary force in solid waste consumption and are widely used in urban construction and road development, effectively realizing the resource utilization of solid waste.
