Bitumen is widely used as an essential binder for many applications due to its excellent adhesive properties, waterproofing, and high durability. However, the conventional application of bitumen involves on-site melting at high temperature exceeding 250°C, necessitating rapid pouring on the surface with additional torch-on, which poses complications and safety risks. Moreover, the on-site melting process releases harmful gases, including hydrogen sulphide and volatile organic compounds (VOCs), endangering workers and nearby areas. To address these challenges, there is a need to develop a safer form of bitumen that does not compromise material performance. This technology transforms solid bitumen into a single-component liquid bituminous coating at room temperature via a simple and cost-effective formulation using solvents, fillers, and additives. The fillers used in the single-component liquid bituminous coating can be made from waste materials such as food waste. Such sustainable fillers could offer comparable material performance to conventional industrial fillers. This high-performance bituminous coating has excellent workability at room temperature, fast drying, and easy production without the need for heating. Thus, this technology eliminates the hazards associated with conventional application of bitumen, providing a safe and energy-saving alternative.

Liquid fuels from biogas are a promising source of renewable and clean energy as they give a lower emission of sulphur dioxide, nitrogen oxide, and soot than conventional fossil fuels. They are sustainable and economically viable as they can be obtained from agricultural waste. However, transforming biogas into a high-value liquid fuel equivalent to diesel or gasoline requires a costly two-step process.  The technology developer has developed a novel enhanced capsule catalysts with unique core-shell structures that enable the production of high value-added liquid fuels from biogas in a single step with only one reactor. These capsule catalysts directly convert synthetic gas (syngas) into liquid fuels, which have improved petrol-like qualities. Therefore, these liquid fuels can be used either as diesel or gasoline substitutes without any modification to engines and existing refuelling facilities. The technology developer seeks companies looking for renewable and clean energy through the gas-to-liquid (GTL) technology to license and commercialise this technology.  The novel enhanced capsule catalysts have a unique core-shell structures to produce liquid fuels from biogas in a single step. The capsule catalysts have the following properties: Dual functionalities, which bring about gas-to-liquid reactions while enabling catalytic cracking and isomerisation, thus achieving a one-step process Excellent durability and high surface area, enabling a higher yield of liquid fuel A robust mesoporous framework that is optimised for the conversion rate of reaction High selectivity for shorter-chain or light hydrocarbon (C5-C10) and a high CO conversion, allowing biogas to be converted more efficiently into high-value liquid fuels within a shorter period of time The direct conversion of syngas allows liquid fuels to be obtained with properties similar to diesel or gasoline, as a renewable and clean energy source, without any modification to engines and existing refuelling facilities. The technology developed for catalyst production and syngas conversion to liquid transport fuels is highly scalable. This technology has the potential to reduce the overall cost of the process as only one reactor is required with these novel catalysts as compared to two reactors using the existing technology. Biogas has been identified as one of the sustainable and economically viable solutions because the feedstock can be obtained from agricultural wastes and wastewater from industries, either locally or from neighbouring regions. Therefore, this technology has the potential to penetrate the market for catalytic materials in the gas-to-liquid processes.  Suitable for: Poultry farms Food waste treatment plants Wastewater treatment industries  Companies who are looking for renewable and clean energy through the gas-to-liquid (GTL) technology to diversify their energy sources.

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.

Recycling of lithium-ion battery material is becoming an increasing necessity and to execute that task in an environmentally friendly and cost-effective method is as important. The novel method of recycling spent battery material using a redox flow battery approach requires the solid spent battery material to react with liquid electrolyte in the tank. The proposed technology by a Singapore-based research team relates to an electrolyte tank filtration system designed to allow solid particles to freely mix and react with electrolyte in the tank of the flow battery system, while being filtered and prevented from entering the pump and cell stack. The holder is designed to be simply placed into and removed from the electrolyte tank, and subsequently, for the easy removal of the solid from the holder itself. This innovation will allow the continuous running of the flow battery system while changing the filter periodically. The research team anticipates that companies planning to utilise redox flow battery recycling method would require the use of such a filter system to reduce the downtime of the entire system. The team is seeking to collaborate with an industrial partner for further research and development of the filtration system and subsequent licensing of the technology for commercialisation. The electrolyte tank filtration system allows free mixing of electrolyte with solid reactants, while preventing the solid particles from entering the pump and cell with the electrolyte Flexibility in addition and removal of multiple filter holders Ease of removing filter paper and solid product from filter holder Able to run flow battery continuously without having to stop for filter removal, leading to no downtime of the system While this technology is designed specifically for the recycling of solid spent battery materials using the redox flow battery system, it can be adapted to be deployed in any flow battery applications that requires filtration of solids reactants from a liquid electrolyte. Based on a non-exhaustive secondary research by the team, there is no “state-of-the-art’ filtration system designed for redox flow battery used for battery material recycling. Filtration systems in the market are not specifically made for the purpose of recycling battery material in a flow battery and therefore do not come with the features and the advantages that come with the proposed technology. Present technology can only allow for such filtration batch by batch, causing stoppages and idle time for the entire flow cell system.
