PolyU researchers introduce biomineralization as a sustainable strategy against microbial corrosion in marine concrete

Microbially induced corrosion (MIC) is a prevalent issue in marine environments, leading to structural damages such as cracking in concrete infrastructure. This corrosion poses a persistent challenge, significantly reducing the lifespan of marine structures and resulting in substantial economic losses. In response to the need for an effective solution to combat the marine corrosion on concrete, researchers of the Hong Kong Polytechnic University have developed a biomineralization approach to protect marine concrete from MIC.  Prof. Xiang-dong LI, Dean of Faculty of Construction and Environment, Director of Research Institute for Sustainable Urban Development, Chair Professor of Environmental Science and Technology, and Ko Jan Ming Professor in Sustainable Urban Development, has led the research that successfully introduces a novel biomineralization strategy, which effectively isolates marine concrete from MIC, thereby contributing to the achievement of sustainable coastal structures.  MIC on concrete usually occurs in harsh environments with the presence of corrosive microorganisms, such as sewage structures, wastewater treatment plants, and marine structures. The formation of a biomineralized film on concrete surfaces is typically considered to be the major anticorrosion mechanism as it can provide a barrier to inhibit corrosion. Prof. LI said, “The biomineralization technique serves as an environmentally friendly coating method for controlling concrete corrosion, with minimal impact on the overall biofilm communities. Also, it utilises carbon dioxide to produce mineral precipitates, enhancing the durability of concrete structures. This process not only reduces the carbon footprint and energy consumption of marine infrastructure throughout its lifespan, but also makes a valuable contribution to carbon neutrality and sustainability.” The study showed the biomineralization treatment effectively prevents corrosion by reducing the total  and relative abundance of sulfate-reducing bacteria (SRB). SRB is a type of anaerobic bacteria and can produce hydrogen sulfide, which is corrosive and can lead to material deterioration.  The biomineralized film acts as a protective layer, controlling sulfate diffusion and isolating the concrete from the corrosive SRB communities. This protective mechanism significantly extends the lifespan of concrete structures. Moreover, this technique has no negative impact on the native marine microbial communities. Prof. LI added, “If the biomineralized film remains intact, repainting the concrete structures is unnecessary. The utilisation of a single coating treatment eliminates the need for multiple treatments, further minimising the cost and carbon footprint.” This biomineralization strategy has strong potential for applications in corrosive environments, such as marine environments, sewage environments, and water cooling utilities, where concrete corrosion is induced by corrosive microorganisms. The research, titled “Biomineralization to prevent microbially induced corrosion on concrete for sustainable marine infrastructure” was published in Environmental Science & Technology. The study employed a combination of chemical and mechanical property measurements of concrete, along with an analysis of the microbial community of biofilms, to evaluate the effectiveness of biomineralization techniques in inhibiting corrosion of marine concrete. These assessments aimed to enhance understanding of MIC development. The results contribute to the development of new techniques for inhabiting corrosion to achieve sustainable marine concrete structures.  In a sulfate chemical attack, calcium hydroxide and calcium aluminate hydrate will be consumed to form gypsum and ettringite, resulting in expansion stress and matrix fracture (Figure 1a). In an MIC attack, bacteria can colonise the corroded layer, which provides an excellent medium for microorganisms to grow. Microbial activity can extend beyond the corrosion layer near to the surface and spread across the deterioration zone (Figure 1b).  Compared with chemical corrosion, MIC causes more severe damage to marine concrete structures. However, the formation of the biomineralized film on the concrete surfaces led to higher surface pH (potential of hydrogen) and lower surface sulfate concentrations, which also acted as a protective layer to control the diffusion of sulfate and isolate the concrete from SRB communities, decreasing internal sulfate levels (Figure 1c). Considering that the type of colonised surface also affects the treatment effect of biomineralization, the effectiveness of biomineralization will be further investigated for different types of concrete to expand its applicability potential.  In addition, the functional prediction can be used in future studies to obtain a mechanistic understanding of the possible metabolic capability of microbial action on concrete corrosion. This understanding is beneficial for uncovering the mystery between SRB and the lifespan of marine concrete structures.

PolyU researcher recycles textile waste for building clothing as thermal insulation

Textiles account for 10% of carbon dioxide (CO2) emissions, while 85% of textile waste is simply landfilled and incinerated. Buildings in Hong Kong generate 60% of CO2 emission and air conditioners consume 30% of energy. Therefore, providing an attractive technology to recycle textile waste and save building energy simultaneously holds high promise for carbon reduction. Dr Dahua SHOU, Limin Endowed Young Scholar in Advanced Textiles Technologies, Assistant Professor in School of Fashion and Textiles of the Hong Kong Polytechnic University (PolyU) has led a research project to create multi-functional, value-added "building clothing" (BC) from textile waste for carbon reduction. Textile waste, often consisting of blended yarns, is difficult to recycle due to the challenges and high cost of sorting, depolymerisation, and dissolution. Dr SHOU’s research titled, “Development of multi-functional building clothing using textile waste for energy saving and waste reduction,” has recently supported by the Green Tech Fund in Hong Kong.  It proposes collecting textile waste to develop a sustainable building envelope for thermal insulation and radiative cooling by a mass production method. The reuse of textile waste as the thermal insulation for sustainable buildings will be an effective green technology that synergistically combines two crucial components in achieving carbon neutrality in Hong Kong: textile waste recycling and building energy saving. By leveraging photon engineering, nature-inspired design, and heat transfer optimization, the proposed "building clothing" will excel in managing the temperature of buildings. In addition to minimising thermal conductivity, the textile-reinforced hierarchical microstructures and colorants will selectively reflect solar heat, including visible light (VIS) and near-infrared (NIR), while emitting thermal radiation in the long-wave infrared (LWIR) spectrum. Furthermore, it effectively repels water and dirt on the surface, ensuring consistent performance and robustness. This multi-functional "building clothing," enhanced with multi-color aesthetics, is highly durable, lightweight, and flame-resistant, making it compatible with a variety of scenarios such as residential and factory buildings, village houses, stilt houses, substations, container apartments, curtains, canopies, and tents. The reuse of textile waste as thermal insulation for sustainable buildings is an effective green technology that synergistically combines two crucial components in achieving carbon neutrality in Hong Kong: textile waste recycling and building energy saving.
