Pinglu Canal Project: 315 million cubic meters of earth and stone turned waste into treasure
Century Project Pinglu Canal insists on on-site consumption of waste, with a comprehensive utilization rate of over 98%, helping the development of ecology and people's livelihood.
Quick Look
- The Pinglu Canal Project achieved a comprehensive utilization rate of more than 98% by absorbing 315 million cubic meters of earth and stone on site.
- The project transformed slag into 13,900 acres of fertile farmland and building materials, which not only solved the problem of massive waste disposal, but also increased local agricultural production and income through land improvement, achieving coordinated development between project construction and ecological people's livelihood.

Why It Matters
The total amount of earth and stone excavated for the Pinglu Canal Project reached 315 million cubic meters, and the project adopted an on-site consumption strategy to reduce environmental impact.
The Pinglu Canal, a century project that is about to be opened to navigation, has excavated a huge amount of 315 million cubic meters of earth and stone, which is enough to pile up a 1 square kilometer and 300 meter high mountain. The project insists on consuming the waste on-site and not transferring it outward on a large scale: land is lifted and reclaimed, soil is improved, and the former barren hills are transformed into 13,900 acres of fertile farmland; gravel is fixed on the bank, fine mud is turned into pottery, hard stone is used to build ship lock slope protection, and high-quality clay is turned into the raw material of Nixing pottery. The comprehensive utilization rate of earth and stone exceeds 98%. One earth is used for multiple purposes and waste is turned into treasure. The Great Power Project takes into account construction, ecology and people's livelihood, turning project waste into real harvest dividends on the local soil.
Cheng Yaofei, commander of the Pinglu Canal Project Construction Headquarters: The earth and stone excavation for the entire Pinglu Canal project reached 315 million cubic meters, which is like piling up a 300-meter mountain in one square kilometer. The horse road hub is a super project carved out between two mountains. The excavation height reached 188 meters, which is equivalent to the height of a 60-story building.
Cheng Yaofei, commander of the Pinglu Canal Project Construction Headquarters: Comprehensive utilization of earth and stone, and creation of 13,900 acres of fertile farmland through land improvement. The land was filled with earth and rocks. It turned out to be large, deep foundation pits and depressions, with improved crops on both sides.
Tang Xiaofu, associate professor at the College of Agriculture of Guangxi University: The land raised and reclaimed is relatively flat and easy to implement mechanized operations. There are about 300 varieties grown in our base. There are so many varieties, giving local people more choices. The current market price of high-quality watermelons is 2.5 to 3 yuan per catty. The yield of Pinglu Canal eggplants is also very high, with the yield per mu reaching 8,000 to 10,000 catties.
Cheng Yaofei, commander of the Pinglu Canal Project Construction Headquarters: We make comprehensive use of earth and stone, do not transport it to outsiders as much as possible, and turn waste into treasure through a series of transformations. The utilization rate reaches more than 98%, achieving an overall balance. The engineering wasteland has turned into ecological fertile land, and the great power projects have left the dividends in the local soil.
