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.

Food tracking and traceability systems can utilize Distributed Ledger Technology (DLT) and Internet-of-Thing (IoT) sensors to streamline the workflow of food supply chain management. Such a traceability system mitigates the complex business processes and speeds up the workflow of working through multiple business owners along the nodes in the value chain. This Technology Offer is a DLT application that can be used to manage the food supply chain. The technology aims to obtain transparency, ease of transactions and speed of delivery, synchronization, tracking and security. As an example, IoT sensors can be attached to livestock to obtain information about them from the source, and is uploaded to the ledger data of the node. When the livestock is shipped to the manufacturer, shipment tracking data can be uploaded. The transport is thus done with trackable ownership, possession and telemetry parameters such as location, temperature, humidity and activity. The manufacturer then processes the livestock, weighs the meat, packs and labels them. The label has a unique cryptographic QR code or NFC tag that links to the data citing the origins of the meat. The packaged meat is then shipped to the distributors, and eventually reaches the buyer. The final buyer can access a complete record of information and trust that the information is accurate and complete.

The majority of the local indoor farmers grow crops that are harvested for their leaves. One way to increase the growth rate of such leafy greens is to provide a longer period of light. However, some of the crops grown, e.g., spinach, are long-day plants that flower when the light periods are longer than their critical day-length. While important to a plant’s life cycle, this vegetative to reproductive phase change is undesirable for farmers, not only because it shortens the harvest period hence reducing the yield, but also because it changes the taste profile. To tackle this problem, a light recipe that was able to suppress flowering was formulated. Plants grown under this light recipe showed a faster growth rate than those grown under flowering-suppressing short-day photoperiod. Moreover, they do not flower even when the light period has surpassed the critical day-length. Positive results were obtained when this light recipe was tested on spinach and arugula. This technology would work for other long-day crops, and it will be beneficial to indoor farmers who are interested to try it.

The most common cryopreservation media used in laboratories consist of 10% DMSO and 20% to 90% fetal bovine serum (FBS). DMSO was thought to reduce the size of ice-crystals during freezing, thus reducing mortality whereas FBS improves the viability of cells during recovery.  Although effective for cryopreservation of most cell types, FBS poised significant risks, including the possible risk of cross-species virus infections such as the “mad cow disease”, as well as the possibility of triggering an adverse immunogenic response from the recipient. Our serum-free cryopreservation formula allows the cryopreservation of mammalian cells without the need for serum.

This Technology Offer allows automation of the process of monitoring stock levels in the warehouse, and when they drop below a certain threshold, trigger a certain event.  This technology can be used to address the following challenges: What items are on the shelf? What is the current inventory level? What items need to be restocked? How many items need to be restocked?

Multiple Pickup and Delivery Planning (MPDP) is very common in both passenger and cargo transport operations. However, due to the planning complexity, it is impossible to quickly generate good solutions manually to support daily transport operation planning. The MPDP solution developed by the team is able to close the gap by quickly generating transport plans for multiple vehicles with multiple pickup locations and multiple delivery locations.

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.

With increasing reliance on robots within 4 walled environments for picking and the like, the task of the robotics fleet has increased significantly in difficulty. Traditional robotics fleet management systems are system-dependent and do not account for dynamic changes on the ground. This technology offer presents a robot agnostic system that allows for superior fleet optimization for warehouse robots in route planning, job allocation and decision making in potential gridlock situations. With past applications for fleets of 2 to over 100 robots in size in warehouses carrying fast-moving items to semiconductor manufacturing facilities, the robot controller has outperformed OEM robot fleet management software in excess of 40% in total job-completion times. Additional simulation function of the robot controller allows non-robot and robot users alike to determine how many robots to purchase for their fleet according to layout and volumes of current and future facility.

Within the solar energy industry, there is a general motto of "install it and forget it " for solar energy. This idea is largely derived from the research and reliability studies performed on the PV panels themselves but not the PV system as a whole (including inverters and other components). Other PV system components such as inverters contribute to a significant amount of power loss and the losses may vary based on different models of inverters. This technology relates to a method that can reduce measurement errors and achieve normalization among inverters used in PV systems in line with Class A of the updated IEC 61724-1 standard  With this method, the inverter-induced error can be reduced by up to 4.46%. The technology owner is looking for licensing partners to commercialize the test method.
