“…Single-stage processes of wood peroxide fractionation on cellulose and soluble lignin in "hydrogen peroxide-acetic acid-water" medium in the presence of TiO 2 catalysts were developed [14]. The processes of catalytic peroxide fractionation were employed for the green biorefinery of birch wood to xylose, pure cellulose, glucose and liquid hydrocarbons [15], larch-wood to dihydroquercitin, arabinogalactan, microcrystalline cellulose and soluble low molecular weight lignin [16].…”

The kinetic study and optimization of pine wood peroxide fractionation in the medium acetic acid-water over TiO 2 catalyst were firstly accomplished. Kinetic regularities and products composition of green processes of catalytic peroxide fractionation of softwood (pine, abies, larch) and hardwood (aspen, birch) over 1 wt% TiO 2 catalyst in the acetic acid-water medium were compared at the temperature range 70-100°C. For all type of wood the processes of peroxide delignification are described by the first order equations and their activation energies are varied at the range 76-94 kJ/mol. According to FTIR, XRD, SEM, NMR data the cellulosic products of peroxide delignification have a structure similar to microcrystalline cellulose regardless of the nature of wood. Soluble products are presented by organic acid and monosaccharides. The scheme of green biorefinery of pine wood based on extractive-catalytic fractionation of wood biomass on microcrystalline cellulose, hemicelluloses, aromatic and aliphatic acids, monosaccharides, turpentine and rosin was developed. Green and non-toxic reagents and solid catalyst are used in the developed scheme of biorefinery.

In the present work, a kinetic study and optimization of the process of spruce wood peroxide oxidation in "acetic acidwater" medium in the presence of suspended TiO 2 catalyst at temperatures 70-100 °C were accomplished for the first time. The effect of wood species and organic solvent nature on the features of the processes of catalytic peroxide fractionation of wood biomass on microcrystalline cellulose and soluble organic products from lignin and hemicelluloses is described. Solid products of wood peroxide oxidation were characterized by FTIR, XRD, SEM, solid state 13 C CP-MAS NMR and soluble products were identified by GC-MS. The experimental optimization of the process of birch wood oxidation by oxygen in "water-alkaline" medium in the presence of suspended Cu(OH) 2 catalyst was carried out at temperature range 160-180 °C. The scheme of biorefinery of birch wood, based on catalytic oxidative fractionation of wood biomass with the production of pentosans, vanillin, syringaldehyde and levulinic acid was developed. The resulting products are in demand in many areas, including food, pharmaceutical, chemical, cosmetic industries, synthesis of new functional and biodegradable polymers.

“…A large number of 'valorization' or 'biorefinery' publications on food waste or other common organic waste in MSW can be found in the literature [151][152][153][154][155]. Further, numerous research publications indicating the feasibility of resource recovery from homogenous biomass, for example, biofuel residues, crop wastes and sawdust, are also available [156][157][158].…”

Municipal solid waste (MSW) management has emerged as probably the most pressing issue many governments nowadays are facing. Traditionally, Waste-to-Energy(WtE) is mostly associated with incineration, but now, with the emergence of the bioeconomy, it embraces a broader definition comprising any processing technique that can generate electricity/heat or produce a waste-derived fuel. Under the ambit of the circular economy many nations are looking for, additional effort must be made to be sure of acquiring the most updated information and paving a sustainable path for managing MSW in such a frame. In this regard, we have undertaken a critical review of various technologies, with their updated progress, involved in the exploitation of MSW as a renewable resource, along with the critical advantages and limitations on energy and material cycling for sustainable MSW management. Incineration, the most widely used method, is nowadays difficult to further apply due to its dubious reputation and social opposition. Meanwhile, to address the organic fraction of MSW which currently is mostly unrecycled and causes disposal issues, the biological approach presents an attractive option. The new emphasis of bioeconomy leads us to understand how environmental biotechnologies should be better connected/integrated for more sustainable MSW management. This article is concluded with advances of future prospects, which can serve as a timely reminder to encourage competent authorities/researchers to work towards further improvement of the present MSW management system.
