Enzymatic hydrolysis of waste paper is becoming a perspective way to obtain raw material for production
of liquid biofuels. Reducing sugars solutions that arise from the process of saccharification are a precursors
for following or simultaneous fermentation to ethanol. Different types of waste paper were evaluated,
in terms of composition and usability, in order to select the appropriate type of the waste paper
for the enzymatic hydrolysis process. Novozymes enzymes NS50013 and NS50010 were used in a laboratory
scale trials. Technological conditions, which seem to be the most suitable for hydrolysis after testing
on cellulose pulp and filter paper, were applied to hydrolysis of widely available waste papers – offset
paper, cardboard, recycled paper in two qualities, matte MYsol offset paper and for comparison again on
model materials. The highest yields were achieved for the cardboard, which was further tested using various
pretreatment combinations in purpose of increasing the hydrolysis yields.
