“…110 An integrated zero-discharge process has been reported, which can be polished for selective production of HMF (up to 91% yield) and levulinic acid (56% yield) from aqueous seaweed extract using KHSO 4 catalyst. 111 Spent aromatic biomass has been utilised to obtain 5-(chloromethyl)furfural (CMF) with high selectivity (∼80%) using HCl as a cheap catalyst. Authors have demonstrated one-pot conversion of CMF to 5-HMF using PhIO reagent.…”

The growing worldwide concern over the environmental impact of our heavy dependence on fossil fuels has provided impetus for biomass utilisation to produce fuels and chemicals. A cost-effective conversion technology stands as a challenge for biobased fuels and chemicals to be competitive with petroleum-derived products. This review provides an overview of the recent advances in the conversion technologies of biomass, which includes thermochemical and biochemical processes. With a plethora of conversion technologies available, the choice of suitable conversion technology depends on the biomass feedstock availability and the desired end-product. It is observed that present research is focused on the development of catalysts and optimisation of process parameters to improve the economics of conversion technologies. Efforts are also on towards utilisation of cheaper substrate, lignocellulosic biomass and CO 2 -sequestering algae. Though few technologies have reached the commercial stage, conversion technologies for lignocellulosic and marine biomass are still evolving. Further, much impetus is being given to process optimisation for deriving platform chemicals from biomass for value addition and sustainability of the biorefinery concept. Some key developments in these areas are presented in this review.

The applications of lignocellulosic wastes to produce a wide variety of products, including biochemicals, biomaterials, and biofuels, can be an effective solution for utilizing these valuable waste materials. In this study, the production of furan building blocks from bagasse fibers was investigated by treating unbleached fibers with NMMO, [Bmim]Cl, and TMAH at different temperatures using AlCl3 and CrCl2 as the catalysts. The resulted liquors were extracted with CH2Cl2 to obtain furan rich fraction. Analysis of extracted fractions with GC/MS indicates the production of various furanic compounds due to catalytic solvolysis with different solvents at elevated temperatures. 2(3H)-furanone and 2-methyl-THF were the main products of catalytic treatment of bagasse fibers with NMMO. Treatment by [Bmim]Cl resulted in 2,5dihydro furanone as the dominant product at elevated temperatures. Furan carboxylic acid methyl ester and 2, 5-furan dicarboxylic acid dimethyl ester were the main TMAH reaction products with unbleached fibers. The results indicate that the type of solvent affects the solvolysis rate and dehydration of cellulose to furanic compounds. Moreover, increasing the temperature led to an increase in the formation of the furanic compounds.

“…Similarly, Kholiya et al described the extraction of agar/agarose from seaweed producing an aqueous extract followed by its conversion into HMF and levulinic acid. 29 In an alternative approach, Gonzales et al demonstrated that HMF can be sequestrated using granular activated carbon as an adsorbent from hydrolysates from lignocellulose and algal biomass. 30 Another key issue is the seasonal growth of macroalgae, which does not lend itself to an effective all year supply, thereby limiting the size or scope of a potential biorenery.…”
