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.

Pressure sensitive adhesives (PSAs) are viscous resins that are designed to adhere to various substrates under light pressure. Majority of commercially available PSAs are derived from non-renewable petroleum sources such as acrylics and silicones, providing the required bonding performance for either permanent or removable applications for use in labels and packaging. However, conventional PSAs present environmental concerns at their end of life, even when its substrate is biodegradable. The technology on offer is a patented bio-based, compostable PSAs comprising of 95% soy and other bio-derived materials that costs less than petroleum adhesives. These PSAs can bond to a variety of substrates (including paper and foams), contains no solvent or water, lowers CO2 emissions when compared to conventional PSA. It can be applied using standard application techniques (slot die or gravure systems) and upon curing will result in a light, cream coloured film. The technology owner is seeking for R&D collaborations and IP licensing opportunities with Singapore partners to manufacture/utilise the technology in packaging and non-structural applications.

Asia accounts for approximately 70% of the world’s seafood consumption, around 69.6 million metric tons. This is more than twice the total amount consumed by the rest of the world.* Commercially, about 30% of the seafood is not consumed, from bones to offals, to skin/shell/scales. These food loss and waste potentially impose environmental and socioeconomic issues.  The technology provider has developed a green chemical process converting seafood sidestreams into food products that are not only high value but also nutritious, addressing Singapore’s demand to increase production of nutrient dense foods. In addition, this method is efficient and cost effective as it requires basic equipment. The technology provider is looking for R&D collaborators and for test-bedding especially with industries who are producing aquaculture food with high nutritional value and interested to utilise their sidestreams more sustainably. * FAO 2018

Monitoring of contaminants in fluids often require capital-intensive machinery and sampling comes at a hefty price tag. With the advent of tightening regulations across various industries including environmental and food industries, there is a need for a more cost-effective and efficient method to meet the growing demands and regulatory requirements in the market. Molecular Imprinted Polymers or MIPs are one such sensor technology that can potentially address this challenge. MIPs are synthetic materials that are designed to recognize and selectively bind to specific molecules, similar to the way antibodies recognize and bind to antigens. MIPs can be engineered to bind to a wide range of analytes, including organic and inorganic molecules, peptides, proteins, and even whole cells. The unique feature of MIPs is that they possess high selectivity and sensitivity for the target molecules, making them ideal candidates for designing high-performance sensors. This technology relates to a cost-effective online monitoring system using MIPs technology to detect trace levels of chemical and biological contaminants on-site in the fluid phase with low interference, high accuracy, and sensitivity. The automated real-time monitoring system requires little supervision and can be easily operated. The robust sensor is designed for long-term operation and requires minimum maintenance without compromising the reproducibility and integrity of the data. This technology allows monitoring can be applied in industries such as agriculture, food, chemical processes, environment monitoring and waste management. The technology provider is seeking partners that are interested in co-development, R&D collaborations or licensing.

Recently, the rising adoption of Internet of Things (IoT) devices and portable electronics has made electronic waste (e-waste) pollution worse, especially when small and low-power IoT devices are single-use only. As such, low-cost and environmentally friendly power sources are in high demand. The technology owner has developed an eco-friendly liquid-activated primary battery for single-use and disposable electronic devices. The battery can be activated by any aqueous liquid and is highly customisable to specific requirements (i.e., shape, size, voltage, power) of each application. This thin and flexible battery can be easily integrated into IoT devices, smart sensors, and medical devices, providing a sustainable energy solution for low-power and single-use applications. The technology owner is keen to do R&D collaboration and IP licensing to industrial partners who intend to use liquid-activated batteries to power the devices.

The Dilution Air Processing Unit (DAPU) is an ideal solution for small and medium businesses to prepare themselves for the Covid-19 new normal by employing an enhanced air ventilation technique. The DAPU system allows the creation of zones (e.g. sickbays, waiting rooms, etc.) within workplaces with no recirculation of air. This prevents cross-contamination of unclean air in between the zones. This solution is suitable for hotels and other premises to be used for quarantine purposes. The DAPU consists of the following key features: Provides 100% fresh air supply with no recirculation Reduces airborne particles exposure by greater than 60% Achieves 25% energy efficiency in providing 100% fresh air supply as compared to conventional systems Uses fully portable modular approach Can be easily retrofitted to any existing air-conditioning system resulting in lower implementation cost The DAPU can also be deployed in any area without an existing air-conditioning system making it highly versatile.

Spent coffee grounds are one of the major food waste produced globally with several million tonnes being discarded annually. It has been reported that only 6% of the original coffee cherry can be used to make a cup of coffee and the remaining balance are inedible and has no value to the industry. As such, a large amount of residue is currently generated from the coffee industry and disposed of at incineration plants or landfills.   This technology features a cost-effective and scalable thermochemical process to transform spent coffee grounds into carbon-rich solid materials, known as hydrochar, as a form of low-cost solid adsorbents for industrial wastewater treatment. Thermochemical processes are well suited for wet biomass such as spent coffee grounds and utilises mild temperature profiles under relatively low pressures. The process also has the potential to convert other kinds of food waste, such as durian husks, coconut husks, fruit peels etc, into hydrochar.This presents a sustainable solution for creating a circular economy and minimising negative impact on the environment by converting non-edible and no value food waste into a value-added product for food and water industries.

Antimicrobial resistance developed due to the overuse of conventional antimicrobial agents in surface coatings and consumer products is a global concern for treatment of infectious diseases in recent years. To address this concern, US FDA has banned the use of a number of conventional antimicrobial agents in consumer and healthcare products such as hand soaps and hand sanitisers. This raises the importance of alternative antimicrobial agents in antiseptic products. Photoactive antimicrobial agents are effective alternatives which produce highly reactive oxygen species (ROS) when activated by light. These reactive oxygen species display broad-spectrum biocidal activity that destroy microbes by a multi-targeted killing mechanism, which may limit the development of antimicrobial tolerance or resistance. The researchers have developed a stabilised form of a plant-based antimicrobial agent to protect it from environmental degradation. The enhanced environmental stability of this natural photoactive antimicrobial agent has made it suitable to be incorporated in various materials for the self-sterilising product applications and may provide a “greener solution” to limit the spread of pathogens and transmission of infections by indirect contact.
