Technology Features & Specifications
The biorefinery strategy comprises the combinatory use of several platform technologies/processes such as (fungal) enzymatic hydrolysis, (yeast/fungi) fermentation, and other industrial processes such as saccharification, pyrolysis, chemical/physical treatments etc.
Processes have been developed to treat agricultural crop wastes, fruits and vegetable wastes, carbohydrate-rich snacks and beverages, bakery wastes, cellulosic materials and textile wastes into chemicals, precursors, bio-surfactants, bioplastics, bio-colorants.
A number of waste streams have been researched/treated via the bio-refinery strategy:
- Mixed fruits and vegetable waste conversion to succinic acid, a food additive and chemical precursor
- Utilisation of waste bread, bakery waste for succinic production
- Conversion of restaurant food waste to sophorolipids, a bio-surfactant
- Bioconversion of carbohydrate-rich snacks and beverages waste to fructose, followed by subsequent chemical transformation to hydroxymethylfurfural (HMF), a precursor to PET analogue polyethylene furanoate (PEF)
- Textile waste (cotton/polyester blend) recycling to rPET and bio-products, e.g. glucose, biosurfactants
Potential applications may include other food waste streams.
Through the combination of existing industrial technologies, various food waste streams can be converted into a range of high value products, via resource and environmentally friendly routes.
