Research on the Development of Sand and Stone Building Materials Industry in Guiyang City under the Background of"Dual Carbon"
In order to promote the high-quality development and transformation of the sand and stone building materials industry in Guiyang city,and in response to the current disorderly development status of the sand and stone building materials industry in Guiyang city,this article collects the production situation of various sand and stone ores and pre mixed concrete stations at the current stage,and analyzes the problems existing in the sand and stone building materials industry and pre mixed concrete industry in Guiyang city.In accordance with the national"dual carbon"development goal and the high-quality development requirements of the industry,it is proposed to build a"dual carbon"circular development model for sand and solid waste,and implement this model in two steps according to the principle of"reducing and replacing,and determining production based on carbon".To verify the promoting effect of this model on industry carbon emissions reduction,the emission factor method was used to calculate the total carbon emissions of the extensive development model and the carbon cycle model,and it was calculated that the carbon cycle model can effectively reduce carbon dioxide by 1.8209 million tons,generating approximately 127.5 million yuan in economic benefits.This indicates that this model has certain implementation value and will effectively promote the high-quality development and transformation of the sand and stone building materials industry in Guiyang city.
