The Group continued to innovate and deploy a diverse range of sustainable products and solutions to our customers. Examples in key industry domains include: Land Transport • Demand for electric vehicles (EV) and charging solutions have been growing globally as technology advances, lower battery prices as well as national incentives and targets drive EV adoption. Our endto-end AGILTM Electric Vehicle Charging solution comprises a modular EV management platform that supports a charging infrastructure catering to different charger makes and models • We delivered 20 single-deck, fully electric buses to the Land Transport Authority of Singapore. These are the first in Singapore to be capable of quick charging using overhead pantographs at bus interchanges. The customised rapid charging lithium ion batteries have a capacity of between 150-200 kWh and charges up to 3 times faster compared to generic batteries. Every minute of charging using the high power inverted pantograph at the bus interchange will extend the travel range by additional 5 km, making it an efficient and viable solution for intra-city transport • We have developed the capability to retrofit diesel buses with electric drive trains to provide a solution aligned with the reuse principles of the Circular ENVIRONMENTAL → Green Products & Solutions Economy. A MAN A22 diesel bus retrofitted with an electric conversion kit was put into service in Singapore in 2021 Environmental Engineering • We are working with consortium partners to design, construct, commission and deliver two process systems in the Integrated Waste Management Facility (IWMF). The IWMF is part of Tuas Nexus, which is the world’s first integrated waste and water treatment facility conceptualised and planned from the ground up. It is expected to contribute to carbon savings of more than 200,000 tonnes of CO2 annually, equivalent to removing 42,500 cars off the road Aerospace • Our Commercial Aerospace leverages Additive Manufacturing (AM) to produce design-optimised replacement parts for our customers. AM is a greener approach to manufacturing which does away with traditional moulds and tooling as it produces nearto-shape products on demand. This eliminates intermediate wastage while allowing the manufacture of components with complex geometries. It enables low quantity, high mix production that empowers a lean and efficient supply chain for our global business units. We are continuing to scale up AM deployment as part of our commitment to a more sustainable manufacturing ecosystem ST Engineering is designing and constructing two key process systems in the Integrated Waste Management Facility located in Tuas Nexus – a Material Recovery Facility and a Waste-to-Energy plant. These two facilities help close the loop on the waste management cycle in Singapore by increasing recycling efficiency, and generating energy from non-recyclable waste. This helps Singapore to achieve its zero waste goal while reducing our reliance on traditional energy sources. Due to the synergies with the adjacent water treatment facility, the electricity generated by the IWMF can be used to sustain the operations of Tuas Nexus and export excess electricity to the grid. This contribution to the grid is estimated to be able to continually power up to 300,000 four-room HDB flats in Singapore. Additionally, the integration of both waste and water treatment facilities will result in footprint savings of up to 2.6 hectares (~ 4 football fields) as compared to building the two as standalone facilities. → Artist impression of Singapore’s Tuas Nexus IWMF 24 ST ENGINEERING SUSTAINABILITY REPORT 2021 OVERVIEW OUR SUSTAINABILITY APPROACH ENVIRONMENTAL SOCIAL GOVERNANCE AWARDS INDEX
