Biotechnological conversion of spent coffee grounds into lactic acid
Letters in Applied Microbiology, 2018This work investigates the potential bioconversion of spent coffee grounds (SCG) into lactic acid (LA). SCG were hydrolysed by a combination of dilute acid treatment and subsequent application of cellulase. The SCG hydrolysate contained a considerable amount of reducing sugars (9·02 ± 0·03 g l-1 , glucose; 26·49 ± 0·10 g l-1 galactose and 2·81 ± 0·07 g

Deep eutectic solvent-based valorization of spent coffee grounds
Food Chemistry, 2018Spent coffee grounds (SCGs) are viewed as a valuable resource for useful bioactive compounds, such as chlorogenic acids and flavonoids, and we suggest an eco-friendly and efficient valorization method. A series of choline chloride-based deep eutectic solvents (DESs) were tested as green extraction solvents for use with ultrasound-assisted extraction ...

Active biocatalyst for biodiesel production from spent coffee ground
Bioresource Technology, 2018Physical adsorption preserving activity and support reusability was used to directly bond lipase from Thermomyces lanuginosus on citric acid (CA) modified Fe3O4/Au magnetic nanoparticles. A new faster approach has been used for CA ligand exchange, which ensures an high payload of stable enzyme.

Co-liquefaction of spent coffee grounds and lignocellulosic feedstocks
Bioresource Technology, 2017Co-liquefaction of spent coffee grounds (SCG) with paper filter (PF), corn stalk (CS) and white pine bark (WPB) respectively, was examined in subcritical water for bio-crude oil production. The optimum reaction temperature was 250°C, and the mixing biomass ratio was 1:1.

The “COFFEE BIN” concept: centralized collection and torrefaction of spent coffee grounds
Environmental Science and Pollution Research, 2019Spent coffee grounds are the moist solid residues of coffee brewing and in most cases, the disposal is done without any intermediate valorization actions for materials and energy recovery. State-of-the-art applications include extraction of the liquids and application of high-temperature pyrolysis.
