The potential of microwave technology for the recovery, synthesis and manufacturing of chemicals from bio-wastes

Abstract Through a series of case studies it is demonstrated that microwave dielectric heating can be a powerful tool to recover and synthesize valuable molecules from a wide range of biomass types. In addition, under microwave irradiation the production of chemicals from biomass proceeds at markedly lower temperatures (up to 150 °C) compared to conventional heating. This has a secondary benefit in that molecules with a high degree of functionality are produced while conventional heating tends to produce a great proportion of lower value gases. Furthermore, the technical set-up of a microwave reactor can easily accommodate for an in-situ separation of acids and valuable products therewith improving the shelf life of the latter. The benefits of combining hydrothermal conditions with microwave irradiation are also illustrated. In addition, a specialized case of selective heating in a biphasic reaction system is discussed, allowing for improved yields and selectivity.
