Urban pipeline systems are vital, large, long-lived, complex, largely inaccessible, and aging, fraught with deficiencies and inefficiencies that result in massive losses of water resources and energy use. Thus, they present an enormous challenge to making cities sustainable, adaptive, and carbon neutral. This pipeline condition assessment technology is pioneered by experts who have leveraged advances in research and engineering science to deliver unique and optimal performances. The technology introduced the use of Time Reversal (TR) for defect detection and condition assessment of pipelines. In fact, TR technology is reliable, cost-effective, and has a long-range capability. It possesses the unique feature of providing high resolution while being non-intrusive and non-disruptive. The TR technology can detect existing leaks, bursts, blockages, malfunctioning devices (e.g., air valve), pipe wall strength condition, and harmful transient. The software provides the following functionality: Active testing: Actively probing the system to control the resolution of localization Passive testing: To detect bursts and harmful transients Real time monitoring: To assesses system dynamics and demand patterns On-demand and automatically generated reports On demand sensor control and sensor expansion Flexible & High sampling rate

Anti-corrosion is important for piping systems because corrosion can lead to several problems including reduced flow capacity, leaks and ruptures, contamination, increased maintenance costs and reduced lifespan. While there are several approaches to mitigate these problems, a possible approach is to utilise thermoplastic materials which are lightweight, durable, and resistant to corrosion. This technology is a thermoplastic piping system lined with HDPE/LDPE linings that is corrosion-resistant, do not generate any waste (waste material can be recycled) and has a reduced carbon footprint. The piping system is easy to assemble and install, providing long service lives due to the high-quality thermoplastic materials being deployed in the system. By laying these thermoplastic pipes underground using native soil without sand-bedding, a reduction in CO2 is achieved and offers users a sustainable piping solution against conventional piping materials. In combination with proprietary welding technologies, the technology has the lowest rate of leakages with high guarantee of preservation of drinking water quality when used in water piping systems. The technology owner is seeking for co-development and test-bedding opportunities with asset owners to integrate the technology into their infrastructure, particularly with hydrogen producing and transporting companies.

Effective tracking and management of Work-In-Progress (WIP) and inventory across a manufacturing facility are key to maintaining productivity and operational efficiency. Despite this, misplaced inventory and inefficient tracking remain common problems within the sector, leading to time wasted on locating items, losses due to unaccounted inventory, and ultimately, a reduction in productivity.  To tackle these challenges, an innovative solution has been developed that integrates advanced technologies, sophisticated hardware, and robust software features to optimize manufacturing operations. This solution provides real-time traceability of WIP and inventory throughout a factory, thereby reducing time wasted in locating items and preventing losses due to unaccounted inventory.  The solution seamlessly integrates with various systems including Manufacturing Execution Systems (MES), Preventive Maintenance (PM) systems, and Enterprise Resource Planning (ERP) systems. This integration capability allows it to trigger alerts, visualize processes, and reduce waste, thereby streamlining operations and minimizing inefficiencies. 

Offshore land reclamation has been an important strategy for Singapore to meet its land needs. However, the ultra-soft soil in the surrounding waters makes land reclamation extremely difficult. Besides, many infrastructure projects (i.e., tunnelling, deep excavation, etc.) are also challenging when encountering soft marine clay due to its poor engineering properties, such as high water content, high compressibility, and low shear strength. Currently, ordinary Portland cement (OPC) is the most common binder used for soft clay stabilisation through deep mixing or jet grouting. However, OPC is not very effective for the stabilisation of marine soft clay with high water content. In addition, the production of OPC leads to negative environmental impacts such as non-renewable resources, high energy consumption, and high carbon emissions. The technology owner has developed a sustainable novel binder, entirely from industrial by-products, that has high stabilisation efficiency for marine soft clay. Using the same binder content, the 28-day strength of the novel binder-stabilised soft clay can be 2–3 times higher than that of the OPC-stabilised clay. In addition, the novel binder has a lower cost and less environmental impact, making it an economical and sustainable alternative to OPC. This technology is available for R&D collaboration, IP licensing, and test-bedding with industrial partners in the construction and infrastructure sectors.

An improvised LoRaWAN has been developed to enhance data transmission efficiency between LoRa trackers and LoRaWAN gateways addressing the prevalent issue of mid-air data loss due to collisions. This improved protocol enhances the data transmission rate from its current range of 10-30% to 65%. This substantial improvement leads to power savings for IoT end nodes, particularly those powered by batteries, by eliminating the need for data re-transmission. Moreover, the improved protocol also significantly increases gateway capacity, thereby reducing the capital expenditure associated with IT infrastructure.

Wireless monitoring solutions are gaining traction worldwide due to their added benefits of continuous monitoring capability 24/7. An innovative technology has been devised that has a way of converting variations in the reflected wavelength from fiber grating based sensors into intensity variations that can be easily processed through the electronic circuits and transmitted wirelessly. Conventional fiber grating based sensors measure the wavelength shift of the reflected light to determine the mechanical strain experienced by the medium in which the grating is embedded.  This is conventionally done through a Fabre Perot interferometer which is referred to as the Interrogator but is a costly solution. The innovative circuitry eliminates the need of the costly, and typically more bulky interferometer, replacing them with cost effective and compact fiber components configured in such a way that converts mechanical strain into intensity changes.

With a focus on built environment, the digital twin technology developed by a Singapore SME offers a suite of tools to model, analyse and continually optimise entire groups of buildings, portfolios, communities, cities and resource networks across their lifecycle, providing a truly scalable solution to decarbonise the built environment. Bridging the gap between the real world and simulation, the digital twin enables the energy efficient design and continuous operational optimisation of not just single but entire groups of buildings. The digital twin solution investigates operational problems using AI and machine learning, engaging the community feedback in real time. It improves operational decisions by understanding where to focus attention on and facilitate decision making by the building operators. The technology owner is seeking partnerships with large building portfolio owner, product developer, IoT solutions provider who can deploy the digital twin solution for their clients.

Plywood is a preferred material used in furniture and home building for its durability since the Egyptian and Roman times. In 2019, the world consumed 165 million cm3 of plywood and was responsible for the creation of more than 3 billion tons of CO2. Applications for plywood are widespread including construction, home, retail, and office interior works and furnishings such as cabinetry, woodworking, renovations, and outfitting . Regulations and protectionism to slow down deforestation plus the tightening of sustainable forestry management lessen the supply of logging for plywood.  As global demand continues to be strong, the search for a viable replacement for plywood has become more pressing. More importantly, it is important to find a non-wood-based replacement with similar performance to plywood. Plywood is desirable because of its superior performance properties. Alternatives like medium-density boards (mdf) and particle boards are made from recycled wood waste. Unfortunately, plywood can only be made from virgin wood and there are no direct replacements for plywood currently. This technology leverages the global abundance of lignocellulosic fibre waste which is the discarded waste material after the harvesting and production of palm oil, rice, and wheat. The technology transforms these lignocellulosic fibre wastes into a direct replacement for conventional plywood.  This provides a sustainable, economically viable, and environmentally friendly solution to the continuing demand for plywood and the resolution to the growing lignocellulosic fiber waste problem in agri-food-based countries all over the world. The technology owner is open to various forms of collaboration including IP licensing, R&D collaboration, and test-bedding with different types of agrifood sidestreams. In the case of palm biomass waste, rice, and wheat straw waste, the technology is ready for commercialization.
