“…Levulinate esters are the most successful LA derivatives with great industrial importance as additives in fuels, food formulations and cosmetics owing to their flavoring, emulsifying and stabilizing characteristics. 16 Also, LA is a good precursor for solvents such as MTHF, which is recognized as suitable in organic synthesis and polymerization reactions. Owing to characteristics such as low polarity with high octane number, it can be mixed with fuels.…”

Over the years, several studies have focused on integrally exploring lignocellulosic biomass to achieve satisfactory yields of different bioproducts and establish economically viable industrial processes. Among the bioproducts, levulinic acid (LA) has emerged as one of the top platform products derived from biomass, mainly owing to its expanding market economic position, which can stimulate viability and attract the attention of investors in the field. Considered a building block because of its versatile intermediate chemical structure, it can be used to synthesize many compounds with applications in fuels, pharmaceutical and cosmetics industries, food additives and solvents. The main synthesis route for obtaining LA is the degradation of cellulose via acid catalysis. In this context, lignocellulosic biomass is a promising and sustainable way of getting LA. Recent research has explored a potential path to full technological development associated with LA from various biomass and different catalysts. In this scenario, a comprehensive review concerning biomass for LA production and the challenges in the synthesis process is proposed. The primary studies conducted over the years and approaches to using and appreciating residual biomass are also discussed. This work also considers the use of technological tools to optimize the production of LA and seeks to contribute sustainable proposals still little explored, such as the intensification of the process and the use of fruit residues in the synthesis of this promising building block.

Levulinic acid (LA) is considered a versatile chemical building block and has emerged as one of the leading platforms for products derived from biomass. It is regarded as important from an economic perspective. The main route of synthesis to obtain LA is from the degradation of cellulose by acid catalysis, with lignocellulosic biomass being a promising and sustainable way to obtain it. In this study, for the first time, the use of watermelon residues was proposed for the synthesis of levulinic acid, adding value to a residual biomass that has still been little explored for this purpose.Watermelon residues were subjected to acid hydrolysis using H2SO4 or HCl. Two reactors were analyzed for this purpose – autoclave and microwave assisted. The experiments were optimized through a central composite design, where temperature, biomass load, and acid concentration in the microwave were evaluated as variables. In the autoclave, the variables investigated were catalyst concentration and biomass loading.The highest yields, 14.8% and 17% by weight, were obtained with solid fraction (SF) in micro wave (MW). In the best condition obtained in the central composite design, the liquid fraction (LF) and SF were analyzed. It was observed that a clean product, containing only levulinic acid and formic acid, was in the liquid fraction. The MW was more efficient and is a promising alternative for reactions requiring energy. This study contributes to an energy‐saving strategy, using waste and low‐cost catalysts, sustainably contributing to a circular carbon economy based on agricultural waste.
