AbstractBanana peel (BP) is an agrowaste produced in large volumes annually, especially by food-processing industries; however, its disposal is of significant concern. However, recent research suggests that BP is a valuable source of bioactive compounds, which can be converted into value-added products. This article reviews the conversion process of value-added products from BP and provides an outline on the chemical composition of BP and its possible applications. In addition, we also discuss the utilization of BP as a substrate to produce animal feed, biofertilizer, dietary fibers, clean energy, industrial enzymes, as well as its use in the synthesis of nanomaterials. Based on the research conducted so far, it is obvious that BP has a wide variety of applications, and thus, developing a biorefinery approach to adequately utilize BP will help realize its economic benefits to the fullest. Based on the valorization of BP, a scheme for BP biorefinery has been proposed. A material balance for BP biorefinery for 1-ton bone-dry BP is presented and our results show that 432 kg of protein or 170 kg of citric acid, 170 kg of pectin, 325 m

Allylic oxidations of olefins to enones allow the efficient synthesis of value-added products from simple olefinic precursors like terpenes or terpenoids. Biocatalytic variants have a large potential for industrial applications, particularly in the pharmaceutical and food industry. Herein we report efficient biocatalytic allylic oxidations of spirocyclic terpenoids by a lyophilisate of the edible fungus Pleurotus sapidus. This ‘’mushroom catalysis’’ is operationally simple and allows the conversion of various unsaturated spirocyclic terpenoids. A number of new spirocyclic enones have thus been obtained with good regio- and chemoselectivity and chiral separation protocols for enantiomeric mixtures have been developed. The oxidations follow a radical mechanism and the regioselectivity of the reaction is mainly determined by bond-dissociation energies of the available allylic CH-bonds and steric accessibility of the oxidation site.

Currently, the food and agricultural sectors are concerned about environmental problems caused by raw material waste, and they are looking for strategies to reduce the growing amount of waste disposal. Now, approaches are being explored that could increment and provide value-added products from agricultural waste to contribute to the circular economy and environmental protection. Edible mushrooms have been globally appreciated for their medicinal properties and nutritional value, but during the mushroom production process nearly one-fifth of the mushroom gets wasted. Therefore, improper disposal of mushrooms and untreated residues can cause fungal disease. The residues of edible mushrooms, being rich in sterols, vitamin D2, amino acids, and polysaccharides, among others, makes it underutilized waste. Most of the published literature has primarily focused on the isolation of bioactive components of these edible mushrooms; however, utilization of waste or edible mushrooms themselves, for the production of value-added products, has remained an overlooked area. Waste of edible mushrooms also represents a disposal problem, but they are a rich source of important compounds, owing to their nutritional and functional properties. Researchers have started exploiting edible mushroom by-products/waste for value-added goods with applications in diverse fields. Bioactive compounds obtained from edible mushrooms are being used in media production and skincare formulations. Furthermore, diverse applications from edible mushrooms are also being explored, including the synthesis of biosorbent, biochar, edible films/coating, probiotics, nanoparticles and cosmetic products. The primary intent of this review is to summarize the information related to edible mushrooms and their valorization in developing value-added products with industrial applications.

The valorization of rubber seed shell into useful materials for industrial applications in polymer technology is of great interest. The usefulness of this material is borne out of the ease of processing; it’s readily available at low or no cost, and less abrasive to equipment. Literature and research reports have shown that rubber seed shell has gained applications in the adhesive industry as reinforcing additive, in electrode manufacturing, as filler in polymer composites, as sorbent in the uptake of heavy metals during waste water treatments, as starting material in the production carbon materials for value added products for the industry. However, there are still outstanding prospects in the utilization of this material in various areas of polymer technology such as a lignocellulosic source for the production of biodegradable foams, polymer gels, second generation bio-plastics and biofuels, and as surfactants. This review examines the results of a retrospective and prospective study in polymer technology of the latent properties inherent in rubber seed shell with particular emphasis on its utilization in polymer technology.

For the economy is very important to have the amount of money in circulation, sufficient to serve the movement of goods and services without generating inflation, indicating an excess of money, so matching the growth rate of monetary and commodity weight control is an important task of the monetary system in all countries. During the time of the gold standard and bimetallism regulation of the economy as a whole was not considered as an important macroeconomic problem. But the economic crisis of 1929 - 1933 forced to reconsider these views and problems of regulation of financial and credit sphere began to be perceived as a function of a stable level of production and employment. The article describes the monetary factors of inflation in the economy and describes the causes, which can lead to programming of monetary growth in the Russian Federation. As the first group of factors impact on the volume of money in circulation in the national economy, the author defined low value added products produced in the country, based on the external market, and the absence, so the room for maneuver of financial resources to stabilize budget revenues with a deterioration in global market conditions. The weakening of the national currency provides large ruble revenues from exports, which reduces the growth of the budget deficit. But the decline of import revenues, which can compensate for the devaluation of the national currency, leads to higher prices in the domestic market due to the prevalence it offers imported goods. The second group of factors linked to the credit activity of banks, which consists in increasing primary issue in lending importers and secondary, which occurs during the formation of foreign exchange reserves by the Bank of Russia. Result of credit activity of banks is to increase money supply growth and the discrepancy between the higher growth of money in circulation and lower growth rates actually created in the production of value added, which leads to the weakening purchasing power of money and rising prices. Each reason has a direct impact on money supply growth and inflation initiates.

Technical Lignins

The primary aim of modern biorefineries is the efficient conversion of lignocellulosic materials into valuable products. Sugars and oils can be converted into valuable chemicals, but processing of lignin is still a challenge. A vast amount of lignin is incinerated to produce process steam and energy, and only a very small part is used for the production of value-added products. Technical lignins are isolated as by-streams in lignocellulosic refineries, e.g., as kraft, soda, organosolv, and hydrolysis lignins, as well as lignosulphonates. They have a modified structure and contain impurities that are dependent on the processing method. The structure and the composition of technical lignins restrict their subsequent applications. This paper reviews limiting factors in utilization of technical lignins. Four major classes of problems are identified, and approaches to overcoming these problems are suggested.

Abstract Recently, the utilization of wastes, recovery of high value-added products from waste, and their use as raw materials in other industries with the logic of industrial symbiosis has an important issue day by day. In this study, removal efficiency of Reactive Orange 16 (RO16) dye from aqueous solution was studied using TiO2 catalyst recycled from an industrial waste effluent. The recycling of TiO2 waste was acquired from a paints manufacturing industry by sintering the TiO2 containing waste. The catalyst usability of TiO2 containing powder was then investigated in the removal of RO16 dye by photocatalytic oxidation process. In photocatalytic oxidation studies, TiO2/UV and TiO2/UV/H2O2 processes were investigated, where the effect of annealing temperature, the effect of H2O2 concentration, the adsorption and photocatalytic effects on RO16 dye removal were studied. The results showed that 100% RO16 removal was obtained for the 10 mg/L initial RO16 concentration using TiO2 (1 g/L)/UV. At high initial RO16 concentration (50 mg/L), 100% RO16 removal was achieved by adding 10 mM H2O2.
