The next-generation biomass for biorefining

Abstract

Biorefining, which uses biomass as feedstock and converts it into valuable products, is a core technology for the sustainable green industry and has high potential as an alternative to the current petrochemical-based industry. This article covers the requirements for feedstock that should be met for the economic feasibility of a biorefinery. In particular, organic waste that meets several requirements as the next-generation biomass has high potential. However, the complex and significant differences in composition depending on the origin make it difficult to follow the previous system of classification such as cellulose, hemicellulose, and lignin. In particular, several organic wastes contain high value-added bioactive components. Therefore, a strategy for the effective use of high value-added ingredients contained in trace amounts is required, which is briefly introduced in the third section of this article.

Statistical Optimization of Alkali Pretreatment to Improve Sugars Recovery from Spent Coffee Grounds and Utilization in Lactic Acid Fermentation

“…Recently, biorefinery that converts food waste into value-added materials has been attracting attention [5]. SCGs containing carbohydrates, lipids and proteins can be a potential raw material in biorefinery [6]. Various studies have been conducted to produce value-added materials such as biopolymers, biofuels and antioxidants by using the carbohydrates of SCGs as carbon sources for microbial fermentation [7,8].…”

Improved recovery of mannitol from Saccharina japonica under optimal hot water extraction and application to lactic acid production by Lacticaseibacillus rhamnosus

“…Biorefineries, defined as the production of biomaterials from biomass, are a key concept for achieving a circular bioeconomy (Yoo & Kim, 2021). For decades, lignocellulosic biomass as a biorefinery feedstock has been the focus of research, such as coconut waste, Citrus peel, persimmon calyx, and peanut shell (Kim et al., 2023; Lee, Kim, Jung, et al., 2023; Nascimento et al., 2023; Santra et al., 2023).…”

Enhanced Production of Bacterial Cellulose from Miscanthus as Sustainable Feedstock through Statistical Optimization of Culture Conditions

“…As a solution, the concept of replacing fossil fuels with biomass which is a sustainable resource has attracted attention [ 1 , 5 , 6 ]. Various studies are being conducted globally to design carbon-neutral platforms that produce value-added materials such as biopolymers, biofuels, and biochemicals using the biorefinery concept [ 1 , 2 , 7 , 8 ].…”
