Food Waste Valorisation

Only 20% of actual coffee is extracted from beans to produce coffee in its beverage form, leaving the remaining 80% (six million tons annually) deemed as spent coffee grounds (SCG) to be disposed or used in landfills or as non-food product components to make fertilisers, furniture, deodorisers or skin care products. A technology was created to counteract SCG wastage and valorise it for human consumption. This particular invention comprises of methodologies to create two types of ingredients using leftover SCG - oil-grind and water-grind processed SCG. A simple, reproducible method of conching is employed to convert leftover SCG into smooth pastes, where specific conching parameters help refine the SCG to an acceptable particle size, eliminating grittiness in numerous valorised products similar to SCG. The product utilises common ingredients like oil and water to conche SCG with improved taste and textural properties. The shelf stability and nutritional composition (including caffeine) of the ingredients were also validated to ensure the food possessed good sensorial properties and are scale up ready. This technology increases SCG’s potential use as a versatile ingredient in different food applications. The technology provider is seeking off-takers from food manufacturers, food services industry, companies interested to valorise side streams to turn SCG into edible compounds.

This technology aims to tackle the food waste problem in the Thai agricultural sector. Shrimp shell was selected since it constituted a large portion of all crustacean shell waste. Many tons of shrimp shells are discarded daily. However, they contain high amounts of protein, calcium, and umami compounds. Thus, they can be used to fortify food products.  Currently, the instant noodle market still has a limited number of healthy options. Therefore, there is a significant market opportunity to develop a low sodium and high protein instant noodle product.

Eggs are a widely popular protein source, however, egg production requires a significant amount of natural resources. Hence, this technology aims to substitute chicken eggs with plant-based alternatives, which would lead to a reduced environmental impact. Rice bran is the hard outer layer of rice, a byproduct of the rice milling process which is pressed for oil and then discarded. Using rice bran as a source of protein reduces waste and increases resource efficiency, making it a strong potential candidate as an alternative protein source to be produced in Thailand, which is the 6th largest rice producer according to the FAO. This product is high in protein (comparable to chicken eggs), which is hydrolyzed to increase bioavailability, and does not contain cholesterol and saturated fat. It is fit for health and fitness enthusiasts, vegetarians, flexitarians and people with an egg allergy.

Egg white is a well-known super-food as an absolute protein with a complete essential amino acid profile, easily digestible, and no cholesterol. While salted egg yolks are a common ingredient in many traditional Asian dishes, the egg white is discarded as it has limited applications due to its high salt content. This technology valorizes the salted egg white waste from the production of salted egg yolks into a tofu-like form that has many culinary applications. This is done using a patent-pending technique that is developed for desalination and reformation of egg white protein.

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.

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

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.
