Sustainable human development urgently calls for decreasing the cost of energy storage. Continuous massive consumption of dedicated carbon electrode materials with complex internal molecular architectures requires rethinking both the source of materials and the process of their production. Finding an efficient sustainable solution is focused on the reuse and development of waste processing into corresponding high‐value‐added carbon materials. The processing of solid wastes into solid value‐added carbon materials (“solid‐to‐solid”) is relatively well developed but can be a two‐stage process involving carbon architecture rearrangement and heteroatom doping. Processing liquid wastes into high‐value‐added solid material (“liquid‐to‐solid”) is typically much more challenging with the need for different production equipment. In the present study, a new approach is developed to bypass the difficulty in the “liquid‐to‐solid” conversion and simultaneously built in the ability for heteroatom doping within one production stage. Polycondensation of liquid humins waste with melamine (as a nitrogen‐containing cross‐linking component) results in solidification with preferential C and N atomic arrangements. For subsequent thermochemical conversion of the obtained solidified wastes, complicated equipment is no longer required, and under simple process conditions, carbon materials for energy storage with superior characteristics were obtained. A complete sequence is reported in the present study, including liquid waste processing, nitrogen incorporation, carbon material production, structural study of the obtained materials, detailed electrochemical evaluation and real supercapacitor device manufacture and testing.

Development of sustainable bio‐based materials for removal of toxic contaminants from water is a high priority goal. Novel bio‐based binary and ternary copolymers with enhanced ion‐exchange, adsorption and antibacterial properties were obtained by using plant biomass‐derived diallyl esters of furandicarboxylic acid (FDCA) as crosslinking agents and easily available vinyl monomers. The synthesized copolymer materials showed higher sorption capacities for NiII, CoII and CuII compared to the commercial ion‐exchange resins, and they maintained their high metal adsorption capacities for over 10 cycles of regeneration. The synthesized copolymer gels containing 1–5 wt % of the crosslinker showed excellent water absorption capacities. The synthesized copolymers with 1 % crosslinker content showed swelling ratios high enough to also act as moisture absorbents. Synthesized copolymers with crosslinker content of 10 wt % performed as contact‐active antibacterials by inhibiting the growth of Gram‐positive (S. aureus) and Gram‐negative bacteria (E. coli, K. pneumonia) in suspension tests.

Agriculture is the most massive material circulation activity of humans, with significant annual volumes of production as well as substantial amounts of waste. Transforming agricultural wastes into high‐value‐added products is the key to sustainable development with efficient usage of renewable resources. The present study demonstrates the fine‐tuning of the sugar beet pulp processing to access two types of materials for cutting edge applications—supercapacitors and fuel cells. Alkaline fine‐tuning results in N,O‐doped carbon material (CM) with an advantageous combination of surface area and morphology that allows to achieve high specific capacitance (308 F g−1), and excellent stability (>10 000 charge/discharge cycles). Not limited to the CM preparation and characterization, a real device is created in the present study to demonstrate the efficient usage of the carbon electrode in the form of the assembled coin cell. Acidic fine‐tuning, in contrast, yields a methodology for P,N,O‐doped material and optimizes to form active sites with electrocatalytic activity in the oxygen reduction reaction that is used for electricity production in proton‐exchange membrane fuel cells. The developed approach demonstrates the tuning of functional properties and morphology of CMs under experimentally simple conditions using conventional reagents (KOH and H3PO4) and opens up new directions in the circular biomass usage projects.

The presence of anthocyans was studied to determine the anthocyanin profile as a tool for distinguishing grapes of the Don region of autochthonous and hybrid varieties of ARRIVW breeding and other hybrid varieties for isolation and identifying typical characteristics. The composition of anthocyans depends on both the variety and the grape habitat. The presence of 3.5-diglucosides in hybrid varieties was established.

Wine is a complex product which changes its properties at every production stage, however due to the different processes which take place in the production stage can result into the formation of unwanted turbidity, deposition or can lead to distortion of taste. Despite the advances in improving wine stabilization processes, the search for new materials continues. The present work focuses on clarification of wines on the basis of new polymers and carbon materials obtained from bio-renewable raw materials and byproducts from the production of 2,5-hydroxymethylfurfural (5-HMF).

Nowadays, commercial electric double-layer supercapacitors mainly use porous activated carbons due to their high specific surface area, electrical conductivity, and chemical stability. A feature of carbon materials is the possibility of obtaining them from renewable plant biomass. In this study, fungi (Fomes fomentarius) were used as a bio-template for the preparation of carbon fibers via a combination of thermochemical conversion approaches, including a general hydrothermal pre-carbonization step, as well as subsequent carbonization, physical, or chemical activation. The relationships between the preparation conditions and the structural and electrochemical properties of the obtained carbon materials were determined using SEM, TEM, EDAX, XPS, cyclic voltammetry, galvanostatic measurements, and EIS. It was shown that hydrothermal pretreatment in the presence of phosphoric acid ensured the complete removal of inorganic impurities of raw fungus hyphae, but at the same time, saved some heteroatoms, such as O, N, and P. Chemical activation using H3PO4 increased the amount of phosphorus in the carbon material and saved the natural fungus’s structure. The combination of a hierarchical pore structure with O, N, and P heteroatom doping made it possible to achieve good electrochemical properties (specific capacitance values of 220 F/g) and excellent stability after 25,000 charge/discharge cycles in a three-electrode cell. The electrochemical performance in both three- and two-electrode cells exceeded or was comparable to other biomass-derived porous carbons, making it a prospective candidate as an electrode material in symmetrical supercapacitors.

Sugar production is accompanied by the formation of waste in the form of beet pulp. In this study, a procedure is described for turning sugar beet pulp waste into structured carbon materials for making electrodes in supercapacitors. The overall sustainable path is to produce sugar for human consumption and prepare high‐quality carbon material for energy storage.
