Due to increasing environmental awareness and legislation, green supply chain management (GSCM) is essential for organizations. Despite significant research on GSCM principles, there is limited clarity on their specific application to sustainable sourcing and distribution. The research aims to clarify the core principles of GSCM, differentiate sustainable sourcing and distribution concepts, evaluate theoretical frameworks guiding GSCM practices, investigate recent innovations, and identify challenges and barriers to GSCM. This review explores GSCM with a focus on sustainable sourcing and distribution by utilizing the Scopus database. The database is searched from Jan 17th, 2024 to August 25th, 2024. By employing Title-ABS-Key (“green supply chain management” and “sustainable sourcing” or “sustainable distribution” or “framework” or “model” or “innovation” or “challenges” or “barriers”) search, the review includes 266 papers from period 1997 to 2024. The review delves into key theoretical frameworks such as the triple bottom line, stakeholder theory, and resource-based view, etc. and discusses their application in the context of GSCM. Findings show that (i) technological advancements like blockchain, IoT, AI, and big data analytics enhance transparency, optimize logistics, and reduce environmental impact, (ii) material innovations viz. bioplastics and recycled resources promote a circular economy and resource conservation, and (iii) supplier engagement through training, incentives, and collaboration foster sustainable practices. For green distribution, eco-friendly packaging, green transportation, and energy-efficient warehousing are important. The review also illustrates the best practices for the GSCM. The paper also addresses challenges including financial barriers, technological limitations, regulatory constraints, and cultural resistance.

The use of reverse osmosis (RO) in urban wastewater treatment plants is becoming popular due to its efficiency in producing high-quality effluent suitable for various reuse applications. However, the process generates reverse osmosis concentrate (ROC) or reject as a byproduct, which poses significant environmental concerns. One of the primary issues with ROC is the presence of organic micropollutants (OMPs). These pollutants are found in substantial concentrations in reject water, raising concerns about their potential ecological and health impacts. This review provides a summary of the characteristics of ROC from urban wastewater treatment plants, focusing on the concentrations and types of OMPs present. The study shows that ROC contains a variety of dissolved organic compounds, dissolved ions, and organic micropollutants, making its treatment a challenge. The paper discusses various technologies studied for the removal of OMPs in ROC, including adsorption, advanced oxidation processes (AOPs), and other methods. Adsorption is identified as an effective method for the removal of OMPs, although some compounds show lower removal efficiencies. AOPs also have good removal capabilities but at the cost of forming potentially harmful byproducts. Emerging technologies such as forward osmosis combined with adsorption, constructed wetlands, and other microbial processes show promise but require further research for practicality. This paper thus underscores the necessity for continued innovation and optimization in ROC treatment methods to mitigate the adverse effects of OMPs on the environment and public health.

Cotton-based textile industries sustain millions of people’s livelihoods and are significant sources of revenue for the nation’s economy. The enormous amount of biomass, processing wastes, and byproducts generated during cotton processing are usually landfilled or incinerated, which is the cause of environmental pollution and health hazards. Cotton biomass, mainly comprised of cellulose, hemicellulose, and lignin, represents a sustainable feedstock for the fermentative production of value-added bioproducts using microorganisms. Advances in microbial biotechnology have led to the effective valorization of cotton biomass and processing waste into valuable products. To date, cotton-based waste biomaterial has been utilized for microbial production of biofuel, hydrogen, biomethane, enzymes, organic acids, bio-enriched compost, and as a substrate for mushroom cultivation. Furthermore, the use of cotton biomass for developing fungal mycelial-based composite and eco-friendly packaging material is documented. Cotton seed meal, an essential byproduct of the cottonseed industry, is converted into more proteinous products and bioactive peptides via microbial-mediated degossypolization and fermentation. The potential of modern metabolic engineering tools such as gene sequencing and assembly, genome editing, clustered regularly interspaced short palindromic repeats (CRISPR), and cell surface engineering for microbial strain development is summarized. This is the first comprehensive review highlighting the aspects of cotton biomasses and byproducts, their structural composition, pretreatment strategies, and microbial approaches for bioconversion into valuable compounds. This document presents the cotton processing industry with an innovative pathway towards a waste-to-wealth solution via microbial-based biorefineries.

Biochar is a useful bioproduct with a wide range of promising applications. The main objective of this study is to investigate the effect of pyrolysis temperatures on the physicochemical properties of biochar produced from pine wood using a slow pyrolysis methodology. Fourier transfer infrared (FTIR) spectroscopy analysis uncovered that the biochar synthesized at the different temperatures selected possessed distinct functional groups. The elemental analysis confirmed that an increase in pyrolysis temperature led to a rise in the carbon (C) concentration, whereas conversely there is a reciprocal decrease in the levels of oxygen (O) and hydrogen (H). Consequently, biochar produced at high temperatures showed low (O/C) and (H/C) fractions. Surface area (gas adsorption) studies indicated that the biochar surface area and pore volume increase at higher pyrolysis temperature. In contrast, the pore size was found to decrease at high temperatures. It was found that increased pyrolysis temperature resulted in reduced biochar yield. Biochar for use in specific applications like as an adsorbent material is ultimately influenced by the pyrolysis temperature. Therefore, it can be concluded that the results of the current study enhances the understanding on the effect of pyrolysis temperature on biochar synthesis and how different parameters can be used to tailor the material characteristics for specific applications.

Crop residues are valuable sources of lignocellulosic biomass that will continue to be available as long as food production for humanity continues. Maize, a cereal crop that serves as a staple food in many parts of the world and is cultivated in numerous countries, holds great importance. The surge in maize production generates substantial amounts of corncobs which can be used as feedstock for the production of xylitol, a compound with a rapidly growing market, and ethanol. In this study, hemicellulose was extracted from the corncobs to obtain xylose by subjecting them to acid hydrolysis with 1 % H2SO4. Non-conventional yeast strain Candida tropicalis Y6 isolated from rotten vegetables was tested for growth and xylose utilization potential on synthetic and acid pre-hydrolysate medium supplemented with mineral salts. Candida tropicalis Y6 exhibited high growth and sugar utilization. On synthetic medium with xylose as the sole C source it produced 6.71 g/L and 0.38 gg-1 of xylitol showing maximum conversion efficiency (53 %) at 24 h, and also produced 0.3 g/L ethanol at 48 h. When cultured on undetoxified corncob hydrolysate, C. tropicalis Y6 produced 0.41 g/L xylitol and 0.74 g/L ethanol. Its xylose conversion was severely affected in acid hydrolysates possibly due to the presence of inhibitors. This C. tropicalis Y6 strain was distinct from other reports in producing a higher level of ethanol than xylitol during fermentation of corncob acid prehydrolysate pointing towards the ratio of XR and XDH enzymes activities under studied conditions.

农作物秸秆是木质纤维素生物质的宝贵来源，只要人类的粮食生产还在继续，农作物秸秆就会一直存在。玉米是一种谷类作物，是世界许多地区的主食，在许多国家都有种植，其重要性不言而喻。玉米产量的激增产生了大量的玉米秆，这些玉米秆可用作生产木糖醇（一种市场快速增长的化合物）和乙醇的原料。在这项研究中，通过用 1 % H2SO4 酸水解玉米棒，从玉米棒中提取半纤维素以获得木糖。从腐烂蔬菜中分离出的非常规酵母菌株 Candida tropicalis Y6 在添加了矿物盐的合成培养基和酸性预水解培养基上进行了生长和木糖利用潜力测试。热带念珠菌 Y6 表现出较高的生长和糖利用率。在以木糖为唯一碳源的合成培养基上，它在 24 小时内分别产生了 6.71 克/升和 0.38 克/升的木糖醇，显示出最高的转化效率（53%），在 48 小时内还产生了 0.3 克/升的乙醇。在酸性水解物中，可能由于抑制剂的存在，木糖的转化率受到严重影响。与其他报道不同的是，该 C. tropicalis Y6 菌株在玉米芯酸预水解物发酵过程中产生的乙醇水平高于木糖醇，这表明在研究条件下 XR 和 XDH 酶活性的比例。

This study explored the co-valorisation of cassava peel and rice husk into biofuel precursors through pyrolysis. The research involved characterization of the biomass, and thermogravimetric analysis at heating rates of 5, 10, and 15 °C/min. An intermediate pyrolysis was conducted using a laboratory-scale setup with a stainless-steel reactor and a Swagelok double-ended tube, yielding pyrolytic oil for analysis. Proximate analysis revealed cassava peel (CP) contains 9.23 wt% ash, while rice husk (RH) has 16.50 wt% ash respectively, while the combined samples of cassava peel and rice husk (CS) had ash content of 74.27 wt%, fixed carbon of 70.07 wt%, and volatile matter of 75.72 wt%. The heating values for the samples were 17.15 MJ/kg, 15.22 MJ/kg, and 17.06 MJ/kg for cassava peel, rice husk, and combined sample respectively. Ultimate analysis indicated the following elemental compositions: CP (40.95 % C, 5.67 % H, 0.22 % N, 0.09 % S, 52.17 % O₂), RH (40.15 % C, 5.98 % H, 0.41 % N, 0.78 % S, 52.68 % O₂), and the CS (43.06 % C, 6.41 % H, 0.32 % N, 0.41 % S, 49.80 % O₂). Kinetic and thermodynamic analysis from the distributed activation energy models revealed average activation energies of 184.95 kJ/mol (CP), 140.56 kJ/mol (RH), and 125.63 kJ/mol (CS). The pyrolysis products consist of 37.50 wt% pyrolytic oil, 11.12 wt% bio-char, and 51.38 wt% non-condensable gases.

The increasing volume of solid waste generated globally necessitates efficient classification systems to enhance recycling and waste management processes. Convolutional Neural Networks (CNNs) have emerged as a powerful tool for image classification tasks, including solid waste identification. However, difficult external variables including changes in illumination, occlusion, and background clutter can have a big impact on CNN performance. Furthermore, pooling procedures frequently cause classic CNNs to lose spatial information, which might impair performance on tasks requiring extremely fine sense of place. This paper presents a comprehensive study on the application of an improved CNN-based models for solid waste classification. In the present study we explored image data resizing, augmentation technique and hyperparameter tuning to improve the performance of the proposed model. The results demonstrate that the improved-CNN model achieved high accuracy of 94.40 % compared to the conventional CNN and other deep learning model such as ResNet-50, Inception-V3 and VGG-19 (81.83, 66.67, 52.83 and 56.00 %).

全球产生的固体废物数量不断增加，需要高效的分类系统来加强回收和废物管理流程。卷积神经网络（CNN）已成为图像分类任务（包括固体废物识别）的强大工具。然而，光照变化、遮挡和背景杂波等难以解决的外部变量会对 CNN 的性能产生很大影响。此外，池化程序经常会导致经典 CNN 丢失空间信息，这可能会影响对位置感要求极高的任务的性能。本文对基于改进型 CNN 的固体废物分类模型的应用进行了全面研究。在本研究中，我们探索了图像数据大小调整、增强技术和超参数调整，以提高所提模型的性能。结果表明，与传统 CNN 和其他深度学习模型（如 ResNet-50、Inception-V3 和 VGG-19）（81.83%、66.67%、52.83% 和 56.00%）相比，改进型 CNN 模型的准确率高达 94.40%。

Tea (Camellia Sinensis) is a popular and extensively consumable drink after water due to its excellent health benefits and medicinal properties. Global tea production is rapidly increasing to keep up with demand, but this also creates massive waste piles of tea that negatively influence the environment. By 2025, tea consumption is expected to have increased from approximately 6.3 million tons in 2020 to 7.4 million tons. Increasing the intake rate of tea has also been accompanied by a spike in the production of tea waste after usage. The present review study investigates the emerging application of tea waste management. Also, it addresses the sustainable recycling of waste from the tea industry, the beneficial application of biomass in agriculture composting, and other applications. Additionally, a thorough assessment of the manufacture of various value-added products from the generated tea waste. A detailed explanation of the challenges and new prospects of using tea waste in multiple industries, such as energy production and environmental remediation. The outcomes of this review research are essential for the world’s sustainable and environmentally friendly growth. This review will address resource management within the framework of zero-waste principles and a regenerative economy. Also, this study will help academics acquire extensive knowledge about the many sustainable uses of waste from tea production as an economical and environmentally favourable alternative to biomass.
