Abstract:
Recently, agro-waste valorization has become a megatrend of research and development. This is obvious from the point of availability (world widely around 140 billion metric tons/year), cost and underutilization of the material. In our research two types of processing methods were compared, namely, hot pressurized water extraction and extraction with green solvents. These two methods were considered as green alternatives to the traditional pulping methods. Since herbaceous biomass has different composition compared to wood, our focus was particularly on valorization of hemicellulose and lignin components. This study is built as a literature analysis and can be considered as a preparative stage in designing of pilot scale facilities. The value-added hemicellulose- and lignin-based products generated by different processes were compared and their potential applications were discussed. The extraction processes studied resulted in products having different characteristics and as a result different potential application. The processing parameters and operating conditions affecting the quality and quantity of products were evaluated. Predicably, temperature and residence time were identified as key parameters affecting extraction. It was proposed that the combination of these two methods will be beneficial for obtaining high value-added fractions of biopolymers. The complex approach allows us to see the hidden possibilities.
