Construction wastes are constantly happening in the city. Where did these construction wastes go at the end? At the 7th Urban Expo, many bricks were displayed on the booth of the Guangzhou Sanitation Group. The commentary said: "These are permeable bricks . 80% of their original data comes from construction waste."

It is understood that about 3.5 million tons of waste materials are being constructed annually in the main urban area, and construction waste accounts for 30% to 40% of the total township waste, and is rapidly added at a rate of 5%. If the construction waste is only landfilled briefly and not used for resources, its harmful substances will be washed into the water body by rainwater, polluting the water environment, and its dust will also affect air quality.

In order to turn the construction waste into a treasure, there are now two construction scrap plants in the main urban area to recover and reuse the construction waste. Construction waste is converted into renewable resources through processes such as crushing and sieving, and these renewable resources can be turned into valuable materials that become permeable bricks on the sidewalk after 7 minutes of processing. "In a permeable brick , the proportion of materials used by construction waste through renewable resources accounts for 80%." According to the relevant person in charge of Guangzhou Yisan Environmental Protection Technology Company, which belongs to the City Sanitation Group, construction waste can be made into permeable bricks. In addition, it can also generate construction data for various projects such as roads and high-rise buildings.

The reporter noticed that on the booth of the environmental protection company affiliated to the Guangzhou Sanitation Group, a total of 25 types of permeable bricks and curbs made of construction waste were exhibited. According to the Guangzhou Sanitation Group, according to the requirements of the “Plan for the Construction of Waste Consumption Sites in Guangzhou's Main Urban Area”, it is estimated that by 2020, the city will also build 3 waste treatment plants. By then, the utilization rate of waste in the main urban area will reach 80%, which constitutes a comprehensive environmental protection industry integrating construction waste management, treatment, and use.
