Solubilization of MSW with blend enzymes

A process for producing a fermentation product, comprising:

• (a) treating Municipal Solid Waste (MSW) with an enzyme composition comprising a cellulolytic background composition present at a ratio between 40-99% w/w of the total enzyme protein, and further comprising:
• ii) a protease present at a ratio between 5-15% w/w of the total enzyme protein;
• iii) a lipase present at a ratio between 2.5-7.5% w/w of the total enzyme protein;
• and/or
• iv) a beta-glucanase present at a ratio between 10-20% w/w of the total enzyme protein;
• and wherein the enzyme composition further comprises one or more enzymes selected from the group consisting of a pectate lyase, a mannanase, and an amylase;
• (b) fermenting the solubilized and/or hydrolysed MSW with one or more fermenting microorganisms to produce a fermentation product;
• and
• (c) recovering the fermentation product from the fermentation.
