Abstract
Agricultural crop residues include leftover and unmarketable materials, such as crop stover, weeds, leaf litter, sawdust, forest litter, and livestock manure originating from crop cultivation, and post-harvest activities. Such residues are a storehouse of plant nutrients and several other resources and therefore need to be managed in an environment- friendly manner with minimum loss of plant nutrients and other resources that can be recovered. Microbial starter consortia are a key component in the rapid recycling of farm residue wastes and the production of other valuable products, such as biogas, bioethanol/biofuel, enzymes, molecules, and metabolites. Recent advances in microbial biotechnology can also facilitate the conversion of farm residues into economically valuable materials, i.e. soil additives, adsorbents, energy, and enzymes, thereby contributing to a circular economy. This special issue attempts to compile the latest advancements in the field of agricultural crop residue management for enhanced nutrient recycling and resource recovery by the use of compost starters and inoculant formulations.

NANOMATERIALS (BASEL, SWITZERLAND) 2023; 14:83. [PMID: 38202538 PMCID: PMC10780386 DOI: 10.3390/nano14010083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 12/22/2023] [Accepted: 12/25/2023] [Indexed: 01/12/2024]
Abstract
In this work, photoluminescent (PL) carbon nano dots (CNDs) prepared from argan waste were embedded in highly optical transparent poly(styrene-co-acrylonitrile) (PSA) and cyclo-olefin copolymer (COC) matrices, which were further processed into thin films. In the first step, the luminescent CNDs were prepared through thermal processing of fine-groundargan waste, followed, in the second step, by direct dispersion in the polymer solutions, obtained by solving PSA and COC in selected solvents. These two polymer matrices were selected due to their high optical transparency, resilience to various environmental factors, and ability to be processed as quality thin films. The structural configuration of the CNDs was investigated through EDX, XPS, and FTIR, while DLS, HR-SEM, and STEM were used for their morphology investigation. The luminescence of the prepared CNDs and resulted polymer nanocomposites was thoroughly investigated through steady-state, absolute PLQY, and lifetime fluorescence. The quality of the resulted CND-polymer nanocomposite thin films was evaluated through AFM. The prepared highly luminescent thin films with a PL conversion efficiency of 30% are intended to be applied as outer photonic conversion layers on solar PV cells for increasing their conversion efficiency through valorization of the UV component of the solar radiation.

Abstract
The cement industry contributes substantially to world emissions. Sustainable and circular practices are adopted globally to mitigate such emissions. Developing countries like Pakistan lack adaptation to circular and sustainable practices. The study proposes an alternative mix of coal and crop residues that can be used for cement production. The study aims to find the best mixtures of coal with crop residue for combustion purposes in cement industries. The Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) are implemented for the environmental and economic viability of the proposed material mixtures. Moreover, the study seeks to explore risks associated with the implementation of circular practices in the cement industry of a developing country. The study adopts Modified Safety Improvement Risk Assessment (SIRA) for assessing the risks. The results suggest that the partial replacement of coal with bagasse is the most viable mixture with lower environmental emissions and is economically feasible among other alternate mixtures. In terms of risk assessment, there is a lack of governmental support for adopting circular economy (CE) practices and profit uncertainties of these CE practices.

Foods 2023; 12:foods12102010. [PMID: 37238827 DOI: 10.3390/foods12102010] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 04/27/2023] [Accepted: 05/09/2023] [Indexed: 05/28/2023] Open
Abstract
Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm mushroom contains bioactive compounds with both antimicrobial and prebiotic properties, which are distributed in the mushroom mycelium, fruiting body, and spent substrate. The mushroom is rich in nondigestible carbohydrates like chitin and glucan, which act as prebiotics and support the growth and activity of beneficial gut bacteria, thereby maintaining a healthy balance of gut microbiota and reducing the risk of antibiotic resistance. The bioactive compounds in P. ostreatus mushrooms, including polysaccharides (glucans, chitin) and secondary metabolites (phenolic compounds, terpenoids, and lectins), exhibit antibacterial, antiviral, and antifungal activities. When mushrooms are consumed, these compounds can help preventing the growth and spread of harmful bacteria in the gut, reducing the risk of infections and the development of antibiotic resistance. Nonetheless, further research is necessary to determine the efficacy of P. ostreatus against different pathogens and to fully comprehend its prebiotic and antimicrobial properties. Overall, consuming a diet rich in mushroom-based foods can have a positive impact on human digestion health. A mushroom-based diet can support a healthy gut microbiome and reduce the need for antibiotics.

Abstract
Climate change and environmental crises are currently affecting the living environment of both people and the planet in general. This necessitates businesses to have a prompt and effective response to minimize or improve the harmful effects that lead to environmental imbalance and fulfill corporate social responsibility through focusing on transitioning to a model of sustainable economic development and encouraging the development and production of green products. This study discovers that the five factors green creativity, green dynamic capabilities, green transformational leadership, reactive green innovation, and proactive green innovation have a positive influence on and aid in the creation of exceptional green product development performance. A survey questionnaire was used to collect data for this research with the participation of more than 1000 people. These figures reveal that the participants are people who are knowledgeable about environmental issues and are actively interested in environmental protection (as well as people who have used green products). Research using software to support SPSS.20 and AMOS.24 to test the hypotheses. The study serves as a framework to help businesses better comprehend the relationship between economics and the environment with the purpose of providing valuable data and raising awareness for innovation in development models for businesses and organizations.
