Plastic is one of the most serious environmental threats. Plastic is a non-biodegradable substance that releases various hazardous compounds that cause cancer and other serious illnesses, as well as endangering aquatic life and polluting the environment. The use of waste plastic in the production of a variety of nanomaterials can protect people and the surroundings from the dangers of plastic waste, while simultaneously producing useful compounds for other applications. This critical review summarizes the current plastic waste circumstances investigation of the worldwide energy crisis, as well as a recent development in the structural forms and presents a situational investigation of common plastic waste into valuable carbon-based nanomaterials (CNMs) like carbon quantum dots, carbon nanoparticles, Carbon nanotube (CNT), graphene, and 3D porous carbon, which can be used as supercapacitor electrode materials. The impact of various structural alterations on CNMs on the charge storage mechanism has been widely addressed for the manufacture of high-performance electrode materials for supercapacitors, and their future potential. We think that our review reveals a promising long-term strategy for using plastic waste for supercapacitor electrode applications, as well as a new way for humanity's future energy and waste management challenges. © 2022

Conventional concrete significantly affects the environment due to high CO2 emission into the atmosphere during the production process. In order to improve concrete performance and arrest the incidence of global warming, the use of additive materials for cement replacement has been promoted worldwide. This study was designed to investigate the mechanical properties of high-performance fiber-reinforced concrete (HFRC) produced using rice husk ash (RHA) and hybrid fiber (HF) in accordance with the densified mixture design algorithm (DMDA) mix design method. Samples were produced using RHA as a direct replacement for cement at 10%, 20%, and 30%. HF, comprising steel and polypropylene fibers, was added (by volume) to the 20% RHA group mixture to improve the HFRC sample properties. Based on the experimental results, higher RHA contents had a generally negative effect on the fresh properties of the HFRC mixtures. Compressive strength values ranged from 53 to 72 MPa with various RHA and HF content. RHA replacement levels up to 20% had an insignificant effect on the strength development and dynamic modulus of the HFRC samples. However, the addition of HF improved splitting tensile strength, flexural strength, and dynamic modulus remarkably at all curing ages. Furthermore, the 91-day drying shrinkage was in the ranges of 0.032%–0.039% and 0.023%–0.034% using different RHA and HF levels, respectively. Increasing both RHA and HF contents significantly reduced drying shrinkage in the samples. Multivariable regression was also performed, clarifying that all tested results were consistent and had good correlations. The results of this study also provide a potentially effective use for abundantly available industrial waste products such as fly ash (FA) and RHA to promote the production of greener and more sustainable concrete. © IMechE 2023.

Air pollution has become a serious global issue, which has significant impacts on both human health and the environment. Over the past decade, air quality has deteriorated due to various anthropogenic activities including construction, urbanization and industrialization. These activities release hazardous particles and harmful gases into the atmosphere, contributing to poor air quality. Developing countries such as India have been particularly affected, with some of their cities among the most polluted worldwide. To address this serious concern, it is imperative to develop and implement air pollution control technologies for both indoor and outdoor environments. This study focuses on the structured investigation of the performance of locally available air filter media in terms of their removal efficiency for submicron and micron-size particles. Various indigenous air filter media are subjected to rigorous testing to evaluate their overall and size-specific filtration efficiency and corresponding differential pressure drop. The results of these performance evaluations are then compared to their effectiveness in removing coarse and fine particles from the air. This research aims to provide valuable insights into the development of effective air filtration systems to combat air pollution. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Waste generation from food manufacturing facilities poses a serious hazard like environmental degradation, water pollution, and land pollution due to its high nutrient composition. Specifically, solid waste(powder) disposal requires additional energy sources in terms of scientific treatment, structured collection, and disposal packaging according to the safety regulation. Thus, this research discusses the viewpoint of integrating food processing waste as an organic carbon source with BG-11 medium for Chlorella vulgaris(FSP-E) growth. The food processing waste powders investigated in this study were obtained from milk, and biscuit manufacturing facilities. The culture medium was modified by combining both BG-11 and food processing waste powders to identify the optimal algal growth and biochemical *** to the microalgae grown in BG-11 alone(IBG), the combination of biscuit waste and IBG produced higher biomass concentration(44%), with increased lipid(11%), protein(20%), and carbohydrate(57%) contents. Chlorella vulgaris was able to uptake nutrients from the culture medium with combination of food processing waste and IBG thus enhancing its growth. The results obtained also indicate that an integrated culture system using food processing waste and synthetic sources can generate energy out of waste by improving the bio-composition of the microalgae biomass.

Microbially induced calcite precipitation (MICP) is an emerging geotechnical improvement technology that has received wide attention from researchers around the world. The applications of MICP in geotechnical field including soil improvement, surface resistance from erosion, coastal protection, and slope stabilization have been investigated by previous researchers. This paper presents a review on application of MICP for slope stabilization. Three subtopics were selected to be discussed: application of native bacteria, modified MICP methods, and field-scale studies. This review reveals that (1) MICP has the potential for slope stabilization;(2) native bacteria are ideal for use in MICP for application in slopes located in regions with variable cold climatic conditions;(3) to improve the effectiveness of MICP for slope stability, traditional MICP needs be modified;(4) MICP appears to have the potential to be one of the future landslide mitigation strategies since it works effectively in the field-scale test. Additionally, the recommended further researches in MICP for slope stabilization are: (1) Study on the other types of native bacteria for diverse environmental condition is required;(2) to discover the best slope stabilization method, the combination of MICP and other traditional slope stabilization techniques should be investigated;(3) it is critical to investigate the effectiveness of the MICP technology for slope stabilization under various conditions in the field. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Improving energy content and hydrophobic nature of woody biomass can be pursued through torrefaction. This gives torrefied biomass with a low bulk density, potentially increasing storage and transport costs. To overcome this issue, densifying the torrefied biomass is necessary. However, poor binding of particles makes densification challenging without using a binder. Therefore, the aim of this study was to investigate the physicochemical characteristics and techno-economic aspects of torrefied rubberwood biomass (TRWB) when pelletized using various cassava-based binders at different blending ratios. The selected binders included cassava starch (CS), cassava pulp (CP), and cassava chip (CC). Each binder at 5%, 10%, or 15% (wt.) was mixed with TRWB and water before pelletizing using a flat die machine. The results revealed that pelletizing TRWB with different cassava-based binders at various blending ratios influenced the physicochemical characteristics of the TRWB pellets, particularly dimensions, bulk density, fuel and atomic ratios, and energy content. The TRWB pellets demonstrated energy densities in the range of 7.95–11.39 GJ/m3, and their mechanical durability and fine content fell within acceptable ranges. The TRWB pellets maintained their shape during 120 min of water soaking, with water absorption levels varying by binder dose. The pelletizing ability, material, and energy costs of TRWB pellets depend on binder type and dose. CP can be applied as a binder for pelletizing torrefied rubberwood biomass. However, the mechanical durability of the product needs to be above the user requirement or standard. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
