As an important product in the process of human’s pursuit of unrestrained mobility, metro can meet the mobility demand arising from rapid globalized economic development which has become an important means of transportation for people living in modern society. Located in China where the world's largest population resides, Guangzhou metro sees a constant daily average traffic of more than 7.55 million passengers—one of the highest across the country. Under the circumstance of globalized economic development, the emergence of metro plays an important role in easing the great population movement pressure.
Observe the construction and operation of urban underground space 40 meters under the ground and feel the pyramid-like noble beauty processed by infrastructures of information age. Teamed up with Guangzhou Metro Museum, BENTU carries on a regeneration experiment using the soil wastes from the metro project.
Problem Statement and Project Solution
Walking through the underground construction tunnels and metro compartments 40 meters underground in Guangzhou, we are re-examining the relationship between human and land.
There are more than 200 metro construction sites in Guangzhou. Take Shuixi-station construction site of Line No.7 for example, the amount of underground soil wastes generated daily, which are mainly raw soil mixed with large boulder stones, can reach 200 to 300 tons. Guangzhou’s metro coverage has doubled in 3 years, which has led to the generation of huge amounts of underground construction soil wastes. By constantly experimenting with different ways to recycle the disposed waste, we are trying to find a balance that can allow humans to re-establish a valuable and dignified connection with the land.
Creation Process & Result
Soil material is the most common waste in the course of metro construction, which also accounts for the largest proportion. It is hard to grow vegetation because of low fertility. Using the red earth from the Panyu-Square-station construction pit, we carried out a soil material regeneration experiment.
In order to make up for the shortage of strength and ensure it meets the demand of daily use, we’ve conducted the test repeatedly. Our sole object is to allow it to be able to be disposed in the wild after use and degraded to the form of soil easily without causing any harm to the nature while ensuring the material strength at the same time. We renounced the use of more tenacious yet non-degradable plastic fibers but adhere to the use of more easily degradable plant fibers combined with gelatinized minerals. We adopt the use of raw earth technology during production; the no-firing production process can reduce the secondary damage to the nature.
How the soil wastes, who witness and record the urban underground space construction, should be returned to the building of modern social civilization? The commemorative product of Guangzhou metro soil material regeneration has given the soil wastes new lives by letting them become part of our daily lives in the form of utensils and participate in the building of the contemporary values of the metro culture. From the beautiful forms to the emotion connections, from single individual to the whole view of human society, we help soil wastes to connect with the world again with dignity and value.
How does the project reflect the exhibition theme "Cultural Bay Area • Humanistic Design"?
It is undeniable that "the urban underground development" will become an important global subject. The proposal of "the Soil Wastes Regeneration Experiment" and its practice bring more attention and thoughts on the question of "the development of metro under the global economic and political influence, as well as the resulting culture and environmental problems"?
