The main use of bagasse is to produce compost in tequila factories with a long traditional composting that lasts 6–8 months. The aim of this study was to evaluate the degradation of agavebagasse by combining a pretreatment with fungi and vermicomposting. Experiments were carried out with fractionated or whole bagasse, sterilized or not, subjecting it to a pretreatment with Bjerkandera adusta alone or combined with native fungi, or only with native bagasse fungi (nonsterilized), for 45 days. This was followed by a vermicomposting with Eisenia fetida and sewage sludge, for another 45 days.
