Core Viewpoint - The event showcased a new technology for on-site transformation of construction waste, emphasizing the importance of reducing building waste and enhancing resource utilization in urbanization efforts in China [3][4]. Group 1: Technology and Innovation - The project utilizes a "modified solidification" technology that transforms discarded soil and sludge into usable materials through a proprietary "modified adhesive material" [3]. - The modified solidified soil exhibits superior properties such as self-leveling and self-compaction, effectively filling irregular gaps and eliminating ground settlement risks [3]. Group 2: Environmental and Economic Benefits - The project achieved the on-site resource utilization of 12,000 cubic meters of waste soil, resulting in an 80% reduction in carbon emissions compared to traditional cement backfilling methods [4]. - Economically, the first phase of the project saved approximately 3.6 million yuan, with overall costs reduced by 20%-30% [4]. - The mechanized pumping method replaced manual and mechanical compaction, shortening the backfilling period by about 50%, thus allowing more time for subsequent processes [4]. Group 3: Future Applications - This low-carbon, economical, and efficient construction model is expected to be promoted in more municipal public works and underground space developments in Guangzhou, contributing to urban renewal with a focus on waste reduction and resource utilization [4].
