SYNTHESIS AND CHARACTERIZATION OF BIODIESEL FUELS FROM FURFURYL ALCOHOL AND SPENT COFFEE GROUNDS
… were produced from their respective alcohols and coffee oil, using either a basic (K<sub>2</sub>CO<sub>3</sub>) catalyst or an acidic catalyst (H<sub>2</sub>SO<sub>4</sub>). Fatty acid furfuryl esters (FAFurEs) were produced using commercially-purchased cooking oils (canola, olive, corn, …

Α-HYDROXY FATTY ACIDS AND BIOPOLYMERS: NEW FATES FOR LIPID-ENRICHED FOOD SCRAPS
… biomasses were considered: lanolin and spent coffee grounds. At first, we worked with pure saturated fatty acids, in order to investigate and realise an efficient and as-green-as-possible synthesis of α-hydroxy fatty acids. This was achieved by converting fatty acids to the correspondent …

The Mesophilic and Thermophilic Anaerobic Digestion of Instant Coffee Waste Waters
An instant coffee factory's physical waste treatment systems and their resulting waste streams were identified and samples of wastewater were analysed to determine the physical and chemical characteristics relevant to anaerobic digestion. Two wastewater types were chosen for treatment by anaerobic …
