The statistical results of the China Construction Waste Resource Utilization Industry Technology Innovation Strategic Alliance show that in recent years, the total annual production of construction waste in China is approximately 1.55 billion tons to 2.4 billion tons, accounting for about 40% of the total urban waste. Conservatively estimated, in the next 10 years, the average annual production of construction waste in China will exceed 1.5 billion tons. The resource utilization of construction waste is imperative, and scientifically and reasonably sorting construction waste is the foundation of construction waste recycling and utilization.
Reasonable suggestions for sorting construction waste
1. Prediction of construction waste generation
The prediction of construction waste generation is an important basis for determining the scale of project construction, and plays a decisive role in the process selection, overall layout, and project investment of the entire engineering design.
2. Regenerated product solutions and market analysis
There are many types of recycled building materials, and currently commonly used recycled products include recycled concrete bricks, recycled sintered bricks, inorganic road materials, pre mixed mortar, dry mixed mortar, recycled asphalt, etc.
The selection of recycled product solutions for the project needs to be based on the analysis of the building materials market in the project location, prioritizing the use of products with high added value, high economic value, and better market conditions. This is conducive to generating economic benefits for the project and maintaining its normal operation.
3. Determination of Engineering Construction Scale
The main reference factors for determining the scale of engineering construction include: prediction of construction waste generation, analysis of recycled product solutions, project investment scale, supporting technology, national and local policies and regulations, local urban and environmental sanitation special planning, product market, etc.
The determination of project scale can provide a basis and basic parameters for the selection of subsequent construction waste treatment processes and the design of auxiliary public works.
4. Site selection and evaluation
The main aspects that need to be compared when choosing a factory site include geological and hydrological conditions, transportation conditions, geographical location, infrastructure conditions, urban planning, social stability, etc.
When considering project functionality, investment, and other conditions, choose a more suitable project site. A good project site can provide convenience for subsequent project design, construction, construction, and operation, indirectly affecting the price and market of recycled products.
