Food Waste Valorisation

Blowflies are insects often used for scientific research in fields such as forensics, veterinary science, ecology, and biology. Scientists study them at different stages of their lives, including maggots and adult blowflies.This technology relates to a fully operational and scalable multi-species insectary (Arthropod Containment Level 2) which focuses on harnessing the potential of non-medical blowflies for agricultural and waste management sectors. Firstly, blowfly maggots can be produced at scale to act as biodigesters to break down and convert agri-food waste or side streams to valuable blowfly insect protein. With additional processing, bioactive compounds can be extracted from these insect proteins with diverse applications in medicine and industry. When maggots mature into blowflies, they can be deployed for all-year-round insect pollination instead of bees. This can be conducted in controlled environments, including Indoor Vertical Farms, Greenhouses, and Polytunnels. This application has been validated with state-of-the-art UV lighting technology where blowflies are adept at locating flowers and conducting crucial pollination activities. The technology provider is actively seeking collaborative partnerships with stakeholders from the agriculture sector to enhance crop yields for farmers, while also aiming to collaborate with the waste management industry in order to minimize waste generation and transform it into valuable products through recycling.

Lignocellulosic biomass side streams derived from the agri-food value chain such as agricultural residues, have the potential to be converted into high-value products, including biofuel, bio-composite construction materials, and sustainable packaging. Among the various conversion processes, pre-treatment plays a crucial role in maximizing the value of lignocellulosic biomass. The primary objective of pre-treatment is to address the complex and heterogeneous structure of the biomass by removing lignin, reducing biomass size, and increasing the surface area for hydrolysis. Unfortunately, current pre-treatment methods for lignocellulosic biomass are energy-intensive, costly, and produce inhibitory compounds that impact subsequent production stages. To overcome these challenges, this technology offers a catalytic oxidation pre-treatment process. This innovative approach operates under ambient or mild conditions, with a short reaction time, resulting in reduced energy consumption and treatment costs. The technology provider is seeking interested parties from the agricultural, biofuels, or biogas industry to license this catalytic oxidation pre-treatment process to enhance their operations and achieve a more sustainable and cost-effective production of valuable products from lignocellulosic biomass.

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.

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

Keratins are naturally occurring proteins found in hair, feathers, wool and other external protective tissues of animals. They are highly abundant, naturally produced and generally underutilized. At the same time, keratins offer versatile chemical properties that allow interactions with themselves or with other materials to improve behaviour. The technology provider has developed sustainable, biodegradable plastic materials by upcycling keratins derived from hair and feathers. In the preliminary studies, the technology provider has found ways to produce films that have the potential to be used as packaging materials. These films do not disintegrate readily in water, yet they fully degrade in soil within a week. They can be made in combination with other waste-derived biopolymers to improve strength to meet the needs of specific use cases. This technology is available for R&D collaboration, IP licensing, or IP acquisition, with industrial partners who are looking for a green packaging solution and to explore specific-use-case products. The technology provider is also interested to collaborate with the OEM partners having the keratin extraction facility from feathers and hair for the deployment of this technology.

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.
