Activation was shown to signifcantly increase the reactivity of all substrates and the yields of the target products. Impurities of lignin led to decreasing product yields. Keywords: hydrotropic cooking, miscanthus, oat fruit shells, wheat straw, Sibunit-4, mechanical activation, hydrolysis, lignin, glucose, 5-hydroxymethylfurfural, xylose, furfural.
