- Abstract
The large-scale construction of civil engineering buildings has brought significant development in the building industry, but increased the amount of construction waste. The enormous amount of civil engineering construction waste poses tremendous threats to the ecological environment and social development. Vigorously promoting the resource utilization of construction waste is the most fundamental and effective path to solve the construction waste problem. This study aims to further analyse civil engineering construction waste and propose corresponding effective resource utilization countermeasures. Henan Province of China was taken as an example, the deficiencies in the pollution management of civil engineering construction waste were first analysed. The total outputs of construction waste in Henan Province from 2017 to 2020 were predicted using the gray prediction model [GM (1,1)]. Results indicate that ineffective management of waste sources, difficulty in implementing the management system, and outmoded execution of management are concrete manifestations of inefficiencies in the aspect of civil engineering construction waste management. The GM (1,1) model can accurately predict the building construction area. The annual output of construction waste from 2017 to 2020 presents an overall steady growth trend with a large increase in amplitude, and the average annual growth rate is 14.45%. The resource utilization countermeasures of civil engineering construction waste include strengthening the establishment of laws, regulations, and standards, defining the responsibilities of multiple parties, such as government and enterprises, innovating policy mechanism for waste disposal, promoting the application of regenerated products, and perfecting fiscal and monetary policies. This work provides important reference values for strengthening the management of the disposal of wastes generated by civil engineering construction, promoting resource utilization, reducing construction wastes, reducing environmental pollution, saving the land, improving urban building environment and people's living environment, and increasing the regeneration and utilization efficiency of construction wastes.
