Sustainability – the Next Bound of Innovation
Governments and corporations worldwide have embraced green solutions to meet their sustainable growth in making the world better. However, challenges in the form of climate change and rapid globalisation threatens the long term sustainability of developed and developing countries, and present an urgent need for further innovation in sustainable technologies.
Making a Green Impact
ST Engineering empowers our customers for a more sustainable future, through our involvement in the first-of-its-kind Integrated Waste Management Facility (IWMF), as part of Tuas Nexus in Singapore. Apart from supporting the plant design for the Waste to Energy facility, ST Engineering will also build the automated Materials Recovery Facility (MRF), power-island and the balance of plants. These efforts will leverage on advanced technologies to sort metals, paper, cardboard and plastics automatically, the MRF in improving sorting efficiency, contributing towards the overall recycling rate in Singapore and help boost Singapore’s domestic recycling efforts, bringing it closer to achieving its ambitious Zero Waste Masterplan.
In the area of water reclamation, ST Engineering expanded the capacity of Kranji NEWater Factory by 22 MiGD, thereby helping to close our nation’s water loop. This becomes a reality with such continuous innovation and sustainable solutions in delivering water, making more optimize than before. These ventures attest to ST Engineering’s deep engineering expertise, capabilities in designing technically challenging projects, as well as our emphasis on collaboration and global efforts in spearheading the use of sustainable technologies.
The Next Wave of Green Technologies
As climate change pushes sustainability to the fore on the global agenda, a new wave of technologies shows promise in widespread adoption. In the field of solid waste, methods to reduce incineration waste will become increasingly important as landfills run out of capacity. Ash melting technologies can be developed upon to further reduce the volume of ash and to form slag that can be repurposed for use. Heavy metals and soluble salts in incineration ash serve as an alternative resource in constructions. Studies have shown possibilities for incineration ash to be used in building embankments to aid in land reclamation and coastal protection efforts. In wastewater and water treatment plants, increasingly stringent environmental regulations will lead to adoption of zero liquid discharge technologies. Integrated sludge drying systems and electro-dewatering processes hold great potential to further reduce the volume of sludge and minimise transportation and disposal costs. Repurposing sludge as biofuel will also strengthen he creation of circular economies in wastewater treatment processes. Additionally, solutions would have to be found to address the high energy consumption of reverse osmosis. Graphene and ceramic membranes can be used to improve nanofiltration capacities and reduce the energy needed for reverse osmosis. Research into electro-deionisation and biomimetic membrane processes will also allow for the further development of energy-efficient and cost-effective alternatives. With our experience in integrating new technologies at scale, ST Engineering is well placed to implement the next wave of innovations to meet your sustainability needs.
ST Engineering will be participating in the upcoming Singapore International Water Week 2021 (21 June to 2 July). Feel free to contact us for any queries.
