Utilisation of spent coffee grounds into lactic acid
Original language description
Spent coffee grounds (SCG) represent solid waste generated by coffee processing industries. Their disposal represents a serious environmental problem; however, SCG can be valorised within a biorefinery concept yielding various valuable products. This work investigates the potential conversion of SCG into lactic acid (LA). It is organic acid usually used in food and pharmaceutical industries. It has also great potential as monomer for producing the biodegradable plastics. Polylactic acid (PLA) is suitable alternative to traditional plastics. Its large-scale application is limited by high price of lactic acid production. However, high price of production could be reduced by optimization of fermentation and searching of cheaper raw materials. SCG were hydrolysed by 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 glucose; 26.49 ± 0.10 galactose and 2.81 ± 0.07 arabinose) and it was used f
