Original abstract

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.

Enzymatická hydrolýza odpadního papíru se stává perspektivním cestou k získání suroviny pro výrobu kapalných biopaliv. Roztoky redukujících cukrů, které vznikají procesem sacharifikace jsou prekurzory pro následnou nebo simultánní fermentaci na ethanol. Různé druhy odpadního papíru byly hodnoceny z hlediska kompozice a použitelnosti, s cílem vybrat vhodný typ odpadního papíru pro proces enzymatické hydrolýzy. Enzymy Novozymes NS50013 a NS50010 byly použity pro pokusy v laboratorním měřítku. Technologické podmínky, které se zdají být nejvhodnější pro hydrolýzu po testování na celulóze a filtračním papíru, byly použity k hydrolýze běžně dostupných odpadních papírů – ofsetový papír, lepenka, recyklovaný papír ve dvou kvalitách, matný MYsol ofsetový papír a pro srovnání znovu na modelových materiálech. Nejvyšší výtěžky byly dosaženy pro lepenku, která byla dále testována s použitím různých kombinací předúpravy s cílem zvýšit výtěžky hydrolýzy.
