“…Addressing operational challenges related to improved sorbent nano/microparticle shift at elevated gas flow rates requires exploring immobilized particle forms for improved applicability and facilitated recovery. Additionally, the life cycle of bio-based sorbents warrants equal consideration, with life-cycle assessment (LCA) emerging as a crucial tool for estimating environmental impacts throughout the sorbent’s entire life cycle [ 125 ]. Strategies such as reusing spent bio-based sorbents as biofuel or catalysts for multiple applications, and employing renewable energy sources are highly sought after to enhance the efficiency and sustainability of carbon capture processes [ 121 ].…”

Carbon dioxide (CO2) impacts the greenhouse effect significantly and results in global warming, prompting urgent attention to climate change concerns. In response, CO2 capture has emerged as a crucial process to capture carbon produced in industrial and power processes before its release into the atmosphere. The main aim of CO2 capture is to mitigate the emissions of greenhouse gas and reduce the anthropogenic impact on climate change. Biopolymer nanocomposites offer a promising avenue for CO2 capture due to their renewable nature. These composites consist of biopolymers derived from biological sources and nanofillers like nanoparticles and nanotubes, enhancing the properties of the composite. Various biopolymers like chitosan, cellulose, carrageenan, and others, possessing unique functional groups, can interact with CO2 molecules. Nanofillers are incorporated to improve mechanical, thermal, and sorption properties, with materials such as graphene, carbon nanotubes, and metallic nanoparticles enhancing surface area and porosity. The CO2 capture mechanism within biopolymer nanocomposites involves physical absorption, chemisorption, and physisorption, driven by functional groups like amino and hydroxyl groups in the biopolymer matrix. The integration of nanofillers further boosts CO2 adsorption capacity by increasing surface area and porosity. Numerous advanced materials, including biopolymeric derivatives like cellulose, alginate, and chitosan, are developed for CO2 capture technology, offering accessibility and cost-effectiveness. This semi-systematic literature review focuses on recent studies involving biopolymer-based materials for CO2 capture, providing an overview of composite materials enriched with nanomaterials, specifically based on cellulose, alginate, chitosan, and carrageenan; the choice of these biopolymers is dictated by the lack of a literature perspective focused on a currently relevant topic such as these biorenewable resources in the framework of carbon capture. The production and efficacy of biopolymer-based adsorbents and membranes are examined, shedding light on potential trends in global CO2 capture technology enhancement.

Today, facing difficult environmental and sustainability questions, the palm oil industry is an important force in global trade and development. As a transformative solution to these problems, this review assesses the implementation of circular economy (CE) strategies. CE principles promote the transformation of waste into value through recycling, upcycling and other low-carbon innovation applications. This review estimates the capability of palm-based biomass, including palm oil mill effluent (POME) and refinery wastes. It evaluates how different technologies such as gasification are used to change these fuel sources into energy fuels and value-added products for industry. It also involves incorporating Industry 4.0 to boost efficiency and waste value creation into the operation. Although the potential of CE in creating an eco-friendly, profitable palm oil industry is apparent, nevertheless it must overcome all kinds and levels of barriers – from economic to technological to social. This review points out for collaborative efforts, technological advancement, and supportive policies to navigate these challenges, advocating for a unified shift towards sustainability and efficiency in the palm oil sector.

“…As Southeast Asian countries have many agricultural resources such as palm oil and rubber, agricultural forms the local and socio-political economies for tropical countries (Farid et al 2019) leading to a high reliance towards the agricultural sector. Being one of the main industrial sectors, the amount of wastewater produced is high and has a major impact on the environment due to the high content of pollutants in wastewater [7,23]. Southeast Asia's gross domestic product (GDP) grew by an average of 6.3% per year between 2003 and 2016 but the average agricultural growth rate was about 3.2% [24].…”

Wastewater pollution from industrial sector has tremendously increased in recent years and has posed severe environmental and health problems in many countries worldwide. Humans and other living organisms need clean water to sustain life and performing other daily activities, such as growing crops in agriculture, mining, and manufacturing. However, lack of effective water treatment and poor management of water sources caused by wastewater discharge to the environment without sufficient treatment have contributed to the high concentration of organic matter and hazardous compounds. In Southeast Asian countries, several treatments are employed in treating wastewater such adsorption, advanced oxidation process and membrane filtration reactor. As there are limited data demonstrating the most efficient and cost-effective way for wastewater treatment in the Southeast Asia’s industrial sector, this paper aims to examine the existing and advanced methods for treating industrial wastewater in Southeast Asian countries and assess its efficacy in removing contaminants from the industrial wastewater. PRISMA approach was used to conduct the review of this study with 64 articles making the final selection from 5 Southeast Asian countries (Malaysia, Singapore, Indonesia, Thailand and Vietnam). The review found that the anaerobic aerobic-wetland sequential system and a convective sludge dryer removed the highest number of contaminants eliminating almost 99% of chemical oxygen demand (COD), volatile suspended solid (VSS), and volatile fatty acid (VFA) with an added benefit of being cost effective, environmentally friendly and sustainable.
