Microwave and dielectric barrier discharge atmospheric plasma interaction on guava industrial biomass for biomaterial production

AbstractThis research helps to develop a novel and economical method for improving the extraction efficiency of oil and fully valorizing guava fruit processing industrial waste into biomaterial. Dielectric barrier discharge atmospheric (DBDA) plasma is a novel non‐thermal technology that has been widely used in the food processing field of research. In this study, the synergistic effect of microwave (MW) and DBDA plasma treatment under different treatment combinations on the modification of morphological and biochemical properties of the guava pomace powder on improving the efficiency of extraction of biomaterials has been investigated. The response surface model (RSM) model was then constructed using the experimental results of Box–Behnken Design (BBD) to obtain the optimal extraction conditions. The predicted optimal extraction conditions for the microwave power level of 600 W for a treatment time of 90 s under solvent extraction at 420 min; DBDA plasma treatment as 35 kV for 15 min and solvent extraction conditions were determined as 80°C for 360 min causing an increment of the oil yield up to 16.19% when extracted using solvent extractor with ethanol as a solvent. These results indicate that the DBDA plasma treatment previous to the extraction step extraction process can contribute to reducing the duration of extraction by 120 min. The obtained data indicate that the MW and DBDA plasma pre‐treatment before the extraction can reduce the extraction duration, increase the yield, and improve the nutritional quality and functional properties.

Properties and applications of α-galactosidase in agricultural waste processing and secondary agricultural process industries.

Agriculture products form the foundation building blocks of our daily lives. Although they have been claimed to be renewable resources with a low carbon footprint, the agricultural community is constantly challenged to overcome two post-harvest bottlenecks: first, farm bio-waste, a substantial economic and environmental burden to the farming sector, and second, an inefficient agricultural processing sector, plagued by the need for significant energy input to generate the products. Both these sectors require extensive processing technologies that are demanding in their energy requirements and expensive. To address these issues, an enzyme(s)-based green chemistry is available to break down complex structures into bio-degradable compounds that source alternate energy with valuable by-products and co-products. α-Galactosidase is a widespread class of glycoside hydroxylases that hydrolyzes α-galactosyl moieties in simple and complex oligo and polysaccharides, glycolipids, and glycoproteins. As a result of its growing importance, in this review we discuss the source of the enzyme, production and purification systems, and enzyme properties. We also elaborate on the enzyme's potential in agricultural bio-waste management, secondary agricultural industries like sugar refining, soymilk derivatives, food and confectionery, and animal feed processing. Insight into this vital enzyme will provide new avenues for less expensive green chemistry-based secondary agricultural processing and agricultural sustainability. © 2023 Society of Chemical Industry.

Review of mineral resource management in a circular economy infrastructure

Purpose is to substantiate foundations of sustainable management of mineral resources while implementing a circular economy model. Methods. The study has applied following research approaches: synthetic method (unification of the singled out aspects); induction method (analysis of a circular economy features); life cycle assessment (evaluation of the product influence on the environment from the viewpoint of each stage of its life cycle); circular economy toolkit (determination and evaluation of the periodicity of circular economy products and indicators); and circular economy indicator prototype (evaluation of the cyclic product efficiency). Findings. Circular economy is one of the key directions of a sustainable development policy as for conservation and protection of mineral resources; it is aimed at more efficient use and improvement of raw material extraction from industrial waste. Formation of a market infrastructure of the circular economy has been proposed based upon mining sector waste use to process it and reduce as well as to repurpose wasteless production and secondary processing of raw materials. The need has been substantiated to contribute to conservation of mineral resources for their sustainable use on the basis of the development of market infrastructure of a stable economy and mining sector waste use to process it and reduce as well as to repurpose wasteless production and secondary processing of raw materials. Originality. A concept for further development of the circular economy market infrastructure has been specified as a platform of production waste supply/demand to optimize the use and conservation of mineral resources on the principles of sustainable growth. It has been proposed to analyze assessment of business development along the lines of a circular economy while calculating parameters when manufacturing is applying primary mineral resources and industrial waste as a raw material for its further processing. Practical implications. The proposed approach of interaction between economic entities on the basis of a circular economy will provide rational use of mineral resources and contribute to the development of a sector of industrial waste processing. The abovementioned will help terminate decrease in the availability of mineral resources and form new milestones of social development on the principles of environmental friendliness and rationalism in the process of interaction with nature.

Nutritional value of black solder fly (Hermetia illucens Linnaeus, 1758) larvae reared on fermented milk industry waste as an ingredient of fish feed

Black soldier fly larvae are omnivorous and have high activity of amylases, lipases and proteases in their gastrointestinal tract, so they are of interest concerning the processing of various organic industrial and agricultural wastes into biomass suitable for feeding farm animals. Black soldier fly larvae are a new protein-lipid component that seems quite promising for inclusion in the diet of fish, since its cultivation allows processing waste from various industries and agriculture. The protein obtained from black soldier fly larvae has been approved for use as a component of the feed ration for farm animals in the European Union, but the possibility of using black soldier fly larvae in aquaculture has not been fully studied and requires studying of a number of issues. In this study, the nutritional value of larvae grown using fermented milk waste was assessed by the content of fat, protein, moisture, macronutrients (K, Ca, Mg) and micronutrients (Fe, Cu, Mn, Zn, Co, Se), as well as amino acid composition. The content of fat, protein and water was estimated by the extraction/gravimetric method. The content of macro— and micronutrients was measured by inductively coupled plasma mass spectrometry (ICPMS). The amino acid composition was determined by a high performance liquid chromatography (HPLC) method adapted to this task. Chemical analysis showed that the larvae are generally of nutritional value, but additional data on fatty acid analysis and vitamin content are required. In addition, it is necessary to test the feed on fish of various species and ages in order, in particular, to evaluate the effect of the studied component on the palatability of the feed, as well as the digestibility of the chitinous cover of the insect.

The impact of pollutant emissions from co-incineration of industrial waste in municipal solid waste incinerators

A large amount of industrial solid waste (including waste plastics, textiles, wood, etc., which are byproducts of industrial production) urgently needs to be treated. Incineration is undoubtedly the most efficient and convenient method. The existing municipal solid waste incineration plants can be transformed to burn such industrial wastes. However, the potential risks associated with high levels of heavy metals in industrial waste and the air pollution caused by co-incineration pose significant challenges to the co-incineration disposal of industrial solid waste. The change of physical and chemical properties of municipal solid waste and the emission characteristics of flue gas pollutants after co-incineration of industrial waste were studied by means of material flow simulation and experiment. In addition, experiments were designed to study the effects of temperature, calcium sulfur ratio and chlorine content on heavy metal emission during the incineration of industrial waste. The results showed that co-incineration of a certain proportion of industrial waste significantly increased the calorific value of municipal solid waste, but excessive mixing of plastic and paper industrial waste would increase the ash content. Co-incineration of plastic industrial waste can significantly increase HCl, and with the increase of temperature, the transformation of Cl to HCl is more thorough. The increase of temperature can promote the migration of Cr, Pb and Se elements to the gas phase. When Cr, Pb, and Se elements are present in the gas phase, they can combine with other gases and aerosols to form particulate matter and toxic substances, causing air pollution. When Ca/S is 1, Ba, Mn, Ni, Zn can effectively reduce the retention rate of elements in the ash. Under certain conditions, chlorine in industrial waste plastics will react with Zn to form tiny particles and low boiling point chlorides, which will increase its volatility. The mineral components in the ash can also be used for making ceramsite and building materials. These results will provide reference for the pollutants controlling during co-incineration of industrial waste and municipal solid waste process.

Critical Assessment of Hydrogen and Methane Production from 1G and 2G Sugarcane Processing Wastes Using One-Stage and Two-Stage Anaerobic Digestion

Sugarcane is a lignocellulosic crop which is used to produce sugar in sugarcane processing industries. Globally, sugarcane processing industries generate solid and liquid wastes amounting to more than 279 million tons per annum and by-products; namely, trash, bagasse, mill mud, and molasses. The valorisation of waste and by-products has recently increased and is playing a significant role in achieving policies and goals associated with circular bioeconomy and sustainable development. For the valorisation of sugarcane processing industry waste and by-products, a number of technologies are well established and in use, while other innovative technologies are still ongoing through research and development with promising futures. These by-products obtained from sugarcane processing industries can be converted into biofuels like hydrogen and methane via anaerobic digestion. Molasses belongs to the first-generation (1G) waste, while trash, bagasse, and mill mud belong to second-generation (2G) waste. Various studies have been carried out in converting both first- and second-generation sugarcane processing industry wastes into renewable energy, exploiting anaerobic digestion (AD) and dark fermentation (DF). This review emphasises the various factors affecting the AD and DF of 1G and 2G sugarcane processing industry wastes. It also critically addresses the feasibility and challenges of operating a two-stage anaerobic digestion process for hydrogen and methane production from these wastes.

Valorization of Biomass-Derived Polymers to Functional Biochar Materials for Supercapacitor Applications via Pyrolysis: Advances and Perspectives.

Polymers from biomass waste including plant/forest waste, biological industrial process waste, municipal solid waste, algae, and livestock are potential sources for renewable and sustainable resources. Converting biomass-derived polymers to functional biochar materials via pyrolysis is a mature and promising approach as these products can be widely utilized in many areas such as carbon sequestration, power production, environmental remediation, and energy storage. With abundant sources, low cost, and special features, the biochar derived from biological polymeric substances exhibits great potential to be an alternative electrode material of high-performance supercapacitors. To extend this scope of application, synthesis of high-quality biochar will be a key issue. This work systematically reviews the char formation mechanisms and technologies from polymeric substances in biomass waste and introduces energy storage mechanisms of supercapacitors to provide overall insight into the biological polymer-based char material for electrochemical energy storage. Aiming to enhance the capacitance of biochar-derived supercapacitor, recent progress in biochar modification approaches including surface activation, doping, and recombination is also summarized. This review can provide guidance for valorizing biomass waste to functional biochar materials for supercapacitor to meet future needs.

ABSTRACT In this study, the removal of RhB from water by furfural residue (FR) biochar was prepared by hydrothermal carbonization (HTC) and citric acid (CA) modification and named this biochar as CHFR (C refers to citric acid, H refers to hydrothermal carbonization and FR is furfural residue). The CHFR were characterized by SEM, FT-IR and XPS, and CHFR was investigated by the effects of initial concentration, adsorbent dosage, pH, and contact time on the removal of RhB, and the experimental data were analyzed using the adsorption isotherm models, the adsorption kinetic models and thermodynamics, et al. The results showed that CHFR has strong adsorption performance, and the theoretical maximum adsorption capacity of RhB was 39.46 mg·g−1 under the reaction conditions of pH3, the dosage of 1.5 g·L−1, and 120 min contact time, with a removal efficiency close to 100%. the adsorption of RhB by CHFR is spontaneous and endothermic, which is consistent with the Freundlich adsorption, and the isotherm model fits well with the pseudo-second-order model, and the adsorption rate could still be as high as 92.74% after five regenerations, therefore, CHFR is an environmentally friendly and efficient adsorbent with excellent adsorption regeneration performance.

Emergy-accounting-based comparison of carbon emissions of solid waste recycled concrete

The carbon emission emergy factor (Em-CEF) model is applied to evaluate the carbon emissions associated with the traditional concrete production method, fly ash concrete production method, coal gangue concrete production method, and recycled aggregate concrete production method in the complete lifecycle. The highest emission reduction can be achieved when solid industrial waste is used to replace part of the traditional raw materials, and the processing and treatment of industrial waste are simplified. Among the four production methods, gangue concrete production corresponds to the highest emission reduction. When solid waste recycled concrete is applied to reduce carbon emissions, coal gangue concrete can be prioritized.
