Methylbenzenes are among the most important organic chemicals today and, among them, p‐xylene deserves particular attention because of its production volume and its application in the manufacture of polyethylene terephthalate (PET). There is great interest in producing this commodity chemical more sustainably from biomass sources, particularly driven by manufacturers willing to produce more sustainable synthetic fibres and PET bottles for beverages. A renewable source for p‐xylene would allow achieving this goal with minimal disruption to existing processes for PET production. Despite the fact that recently some routes to renewable p‐xylene have been identified, there is no clear consensus on their feasibility or implications. We have critically reviewed the current state‐of‐the‐art with focus on catalytic routes and possible outlook for commercialisation. Pathways to obtain p‐xylene from a biomass‐derived route include methanol‐to‐aromatics (MTA), ethanol dehydration, ethylene dimerization, furan cycloaddition or catalytic fast pyrolysis and hydrotreating of lignin. Some of the processes identified suggest near‐future possibilities, but also more speculative or longer‐term sources for synthesis of p‐xylene are highlighted. Alternative to fossil fuel? Despite the interest in industry and academia in the implementation of routes to renewable aromatics, there is a lack of clear and practical knowledge regarding such methods. Often, it is overlooked that alternatives to lignin exist from which aromatics can be derived. In view of this, this Review will not only summarize the scientific state‐of‐the‐art of the synthesis of aromatics from bio‐derived compounds but also provide some assessment of any commercial implementation and industrial support.
