Leaders from Jiujiang Housing and Urban-Rural Development Bureau Visited Our Company for Inspection and Guidance | Discussing a New Chapter in Sponge City Construction

Recently, leaders from the Jiujiang Housing and Urban-Rural Development Bureau visited our company for inspection and guidance. The two parties conducted in-depth exchanges on sponge city construction technology, the application of ecological porous fiber cotton, and green building practices.

Company leaders Chairman Lin Yongliang and President Kou Shuhua respectively gave special presentations on the Ningbo University Science and Technology Service Building case and ecological porous fiber cotton technology, demonstrating the company's innovative achievements and practical experience in the field of sponge city.

Chairman Lin Yongliang's Sharing

Case of Science and Technology Service Building, Ningbo University

Chairman Lin stated that this case proves the key role of sponge city technology in improving the sustainability of buildings, and it can be promoted to similar climate cities such as Jiujiang in the future.

Chairman Lin focused on introducing the Ningbo University Science and Technology Service Building project. As a national three-star green building (the highest level), the project successfully integrated the concept of sponge city with green building technology. Through innovative designs such as vertical greening, rooftop farms, and rainwater harvesting systems, the building has achieved a win-win situation of efficient resource utilization and ecological benefits:

Rainwater harvesting system:

The rainwater collection and purification system designed and installed by our company has an annual rainwater recovery of 6,000 cubic meters. The purified rainwater is used for green irrigation, sanitary facility flushing, etc., with a water saving rate of over 50%, directly saving more than 10,000 yuan per year.

Vertical Greening and Cooling:

Wisteria green plants on the outer wall and greening in the atrium effectively reduce building energy consumption, and the rooftop farm not only improves space utilization but also provides employees with a green leisure place.

Demonstration Significance:

This project provides a replicable technical template for green buildings in hot summer and cold winter areas, and was awarded Ningbo's first three-star green building operation label.

President Kou Shuhua's Detailed Explanation

Ecological Porous Fiber Cotton Technology

President Kou emphasized that this technology meets Jiujiang's sponge city construction needs of "natural accumulation, natural infiltration, and natural purification", and helps solve the problems of urban waterlogging and water shortage.

President Kou systematically introduced the characteristics and applications of our company's core product—ecological porous fiber cotton—to the inspection team:

Technical advantages:

Pure natural mineral material with a porosity of up to 95.4% and a permeability coefficient of 0.88 cm/s. It has both super load-bearing capacity (5-7T/m²) and ecological friendliness, supports plant root growth, and realizes the integration of multiple functions of "seepage, stagnation, storage, purification, use, and discharge".

Application scenarios:

Road reconstruction:

Replace traditional drainage facilities, alleviate waterlogging and purify rainwater;

Residential area:

Decentralized water storage modules reduce the need for green space subsidence and reduce maintenance costs;

Roof greening:

Lightweight design, with a load of only 87kg/m², to achieve a rain-fed rooftop farm;

Water environment management:

Microbial filter bed technology, no chemical reagents, long-term purification of landscape water.

Engineering Cases:

Xiamen Haicang Vanke City, Longhu Chunjiang Bi'an and other projects have been successfully applied, significantly improving the utilization rate of rainwater resources.

Leaders of the Jiujiang Housing and Urban-Rural Development Bureau highly recognized our company's technological achievements, pointing out that Jiujiang, as a waterfront city, is actively promoting the construction of sponge cities and ecological restoration, and looks forward to deepening cooperation between the two parties.

This inspection laid a solid foundation for cooperation between the two parties. Our company will continue to take "Let every drop of rainwater benefit mankind" as its mission, promote technological innovation in sponge cities, and contribute wisdom and strength to the green transformation of Jiujiang and even cities across the country.
