Integrated process for the production of bio-oil from sludge coming from a wastewater purification plant comprising the following steps: (a) sending wastewater to said purification plant obtaining sludge; (b) subjecting the sludge obtained in said step (a) to liquefaction, obtaining a mixture Including an oily phase consisting of bio-oil, a solid phase and an aqueous phase; (c) sending the aqueous phase obtained in said step (b) to said purification plant. The bio-oil (or 'bio-crude') thus obtained can be advantageously used in the production of bio-fuels which can be used as such, or in a mixture with other automotive fuels. Otherwise, said bio-oil (or 'bio-crude') can be used as such (bio-fuel), or in a mixture with fossil fuels (combustible oil, coal, etc.), for the generation of electric energy or heat.

Process for the production of lipids from biomass comprising polysaccharides. The biomass is subjected to acid hydrolysis to obtain a solid phase and an aqueous phase. The solid phase is subjected to acid or to enzymatic hydrolysis obtaining a further solid phase and a further aqueous phase. The aqueous phases obtained from both hydrolysis steps are subjected to fermentation with an oleaginous yeast. The obtained fermentation broth comprises oleaginous cellular biomass which is subjected to microfiltration for the isolation of lipids. Said lipids can be used in the production of biodiesel or green diesel.
