“…Hence, the conversion of cellulose has attracted worldwide interest; however, the effective degradation of cellulose is a challenge because the polymer has rigid, chemically-stable, and water-insoluble properties, which are induced from the inter-and intra-molecular hydrogen-bondings [15][16][17][18]. A large number of strategies have been applied in this subject [19][20][21][22][23]. Homogeneous catalysts such as sulfuric acid and cellulase enzymes produce glucose in high yields from cellulose [24,25], but these processes suffer from the complicated separation of products from the solution [26] and high costs.…”

Conversion of biomass to renewable and valuable chemicals has attracted global interest in order to build up sustainable societies. Cellulose is the most abundant and non-food biomass; however, the low reactivity of cellulose has prevented its use in chemical industry except for the paper manufacturing. The heterogeneous catalysis for the conversion of cellulose has been expected to overcome this issue, because various types of heterogeneous catalysts can be designed and applied in a wide range of reaction conditions. Furthermore, solid catalysts are easily recovered and reused. In this review article, we show the present situation and perspective of heterogeneous catalysis for the transformation of cellulose into useful platform 2 chemicals.

“…One promising biologically based chemical is 2,5-furandicarboxylic acid (FDCA). This chemical building block has been mentioned for many years as having great potential for future applications (1,2). Recently, new technologies in the polymer industry have already led to the production of an FDCA-based polymer, polyethylene furanoate (PEF).…”

In the search for useful and renewable chemical building blocks, 5-hydroxymethylfurfural (HMF) has emerged as a very promising candidate, as it can be prepared from sugars. HMF can be oxidized to 2,5-furandicarboxylic acid (FDCA), which is used as a substitute for petroleum-based terephthalate in polymer production. On the basis of a recently identified bacterial degradation pathway for HMF, candidate genes responsible for selective HMF oxidation have been identified. Heterologous expression of a protein from Methylovorus sp. strain MP688 in Escherichia coli and subsequent enzyme characterization showed that the respective gene indeed encodes an efficient HMF oxidase (HMFO). HMFO is a flavin adenine dinucleotide-containing oxidase and belongs to the glucose-methanol-choline-type flavoprotein oxidase family. Intriguingly, the activity of HMFO is not restricted to HMF, as it is active with a wide range of aromatic primary alcohols and aldehydes. The enzyme was shown to be relatively thermostable and active over a broad pH range. This makes HMFO a promising oxidative biocatalyst that can be used for the production of FDCA from HMF, a reaction involving both alcohol and aldehyde oxidations.

“…Since the ''carbon-neutral'' sustainable chemistry became increasingly important issue, [1][2][3][4][5][6][7][8] the utilization of waste biomass such as lignin has long been expected to develop. 4 Although biodegradable materials was thought to be one of the target products, recent social demands require the certain characteristics or properties of such materials to replace ordinary plastics with bio-based materials.…”

Polyesters of 2-Pyrone-4,6-dicarboxylic Acid (PDC) as Bio-based Plastics Exhibiting Strong Adhering Properties

2-Pyrone-4,6-dicarboxylic acid (PDC), a chemically stable metabolic intermediate of lignin, its bis(hydroxyethyl) derivative (BHPDC) and bis(hydroxyethyl) terephthalate (BHT) were polymerized to prepare the corresponding polyesters carrying the oxyethyleneoxycarbonyl(2-pyrone-4,6-diyl)carbonyl and oxyethyleneoxy-terephthaloyl units [x and y units, resp., x þ y ¼ 1] by polycondensation eliminating water and/or 1,2-ethanediol molecules. The polyesters were mostly stable up to 210 C, after that the degradation of pyrone ring commenced. These polyesters exhibited strong adhering properties against metal, glass and surfaces with increasing the x unit content to 0.4-0.6, such as about 50-60 MPa for SUS/polyester/SUS or Al/ polyester/Al samples, by the JIS K 6849:1994 testing method of tensile strength. As the fracturing plane was the midst of the polyester layer and at the interface, the polyester was tenaciously adhering to the metal surface.
