Abstract: Abstract The construction waste in China is mainly composed of concrete blocks and bricks, and the output is huge. However, there are significant differences in the technical properties of concrete blocks and bricks, and the non separated recycled aggregates produced from Two kinds of engineering materials often find that it difficult to meet the requirements for the use of high-grade road base course. This article applies the optoelectronic technology method for the sorting of construction waste that is the most widely and successful used for grain processing and sorting. The technology is applied to design the brick and concrete block separation scheme and improve the traditional process of construction waste sorting. The improvement is expected to achieve high value-added resource utilization. At the same time, it actively responds to national policies on energy conservation and emission reduction, circular economy, and the construction of a conservation-oriented society.
