Sago residue is being explored as an alternative material in construction materials because of its natural source, good performance, eco-friendly nature, and biodegradable properties. Sago residue is categorized into particles and fiber, so it has various fabrication methods and applications. This study examines various sago residue extraction methods, including traditional manual techniques, mechanical processes, and chemical or enzymatic methods, highlighting their impact on the properties of construction materials. Furthermore, factors such as constituent materials, processing methods, composition, fiber and particle size, environmental conditions, and manufacturing processes can all influence the physical and mechanical properties of sago residue-based construction materials. This review emphasizes the importance of material characterization in understanding their suitability for specific construction applications, ensuring product quality and safety, and identifying opportunities for sustainable development in the construction industry. It was also shown that this study provides important insights and explores the potential of sago waste as a construction material that can be degraded in the environment. Future research may explore the impact of fiber and fiber orientation treatments on the heat resistance, sound absorption ability, and tribology properties of construction materials made from sago waste.

While wood has been a renewable and versatile material for centuries, its susceptibility to biotic and abiotic degradation remains challenging. Traditional preservation methods, though effective, raise increasing concerns about environmental and health toxicity, cost, and post-consumer fate of the treated wood products. To address these issues, more sustainable and effective preservation methods have emerged. This review examines the latest innovations, particularly nanotechnology and self-emulsifying drug delivery systems (SEDDS), highlighting their applications, advantages, challenges, and research gaps. It focuses on literature from 2019 to 2024, exploring advancements in wood preservation. It also discusses the potential of these technologies to revolutionize wood preservation, offering promising and innovative solutions for the future.

Climate change is a serious global challenge with rising greenhouse gas emissions driving the need for effective carbon sequestration strategies. Carbon sequestration plants, such as fast-growing tree species, bioenergy plants, agroforestry systems, and blue carbon ecosystems, play a critical role in capturing and storing atmospheric carbon dioxide. Despite increasing interest, there is a lack of integrated reviews that connect plant-based sequestration mechanisms with emerging technologies and policy instruments such as carbon credits. This review explores the mechanisms of carbon sequestration in plants, emphasizing the contributions through aboveground and belowground biomass accumulation, soil carbon retention, and microbial interactions. Key plant species, including Eucalyptus, Paulownia, bamboo, and mangroves, have demonstrated high sequestration potential and are discussed. This article aims to synthesize current knowledge while identifying opportunities for enhancing carbon sequestration through biotechnology and policy. This review also highlights emerging biotechnological advancements, such as genetic modifications, to improve carbon uptake efficiency and growing potential of blue carbon ecosystems. Emerging digital tools such as AI-based monitoring and blockchain supported carbon credit tracking are discussed as complementary systems to improve data transparency, verification and trust in carbon markets. By aligning scientific innovation with policy and social engagement, carbon credit can serve as a key element for climate mitigation strategies.
