Olive Mill Wastewater Valorization through Steam Reforming Using Multifunctional Reactors: Challenges of the Process Intensification

Olive oil mill wastewater (OMW) is a polluting stream derived from the production of olive and source environmental pollution; this relevant in many countries around world, but particularly all Mediterranean region where major producers are located. In effluent, several pollutants present—namely, sugars, fatty acids, polyphenols, among others. Nowadays, to reduce pollutant load, treatment techniques applied, these technologies have numerous cost efficiency problems. For reason, steam reforming OMW (OMWSR) presents as good alternative, because process decreases load simultaneously valorizes waste with green H2, which consistent perspective circular economy. Currently, OMWSR an innovative alternative scientific field high potential. last few years, some groups studied used reactor configurations, aiming improve process’ effectiveness. review, treatment/valorization processes, developments on catalysis for (or similar species present effluent), well advances performed multi-functional reactors addressed.
