“…The second phase, LCI analysis, collects LCI data (e.g., mass and energy balances, and environmental emissions) based on the goal and scope defined in the first phase. , The LCI data used in previous engineered wood products LCA mainly come from four sources, namely literature, process-based simulation, databases (e.g., ecoinvent and US LCI database), ,, and survey data. ,,,− For multiproduct systems, system expansion or allocation can be used to determine the environmental burdens associated with individual products. , …”

The building sector, including building operations and materials, was responsible for the emission of ∼11.9 gigatons of global energy-related CO2 in 2020, accounting for 37% of the total CO2 emissions, the largest share among different sectors. Lowering the carbon footprint of buildings requires the development of carbon-storage materials as well as novel designs that could enable multifunctional components to achieve widespread applications. Wood is one of the most abundant biomaterials on Earth and has been used for construction historically. Recent research breakthroughs on advanced engineered wood products epitomize this material’s tremendous yet largely untapped potential for addressing global sustainability challenges. In this review, we explore recent developments in chemically modified wood that will produce a new generation of engineered wood products for building applications. Traditionally, engineered wood products have primarily had a structural purpose, but this review broadens the classification to encompass more aspects of building performance. We begin by providing multiscale design principles of wood products from a computational point of view, followed by discussion of the chemical modifications and structural engineering methods used to modify wood in terms of its mechanical, thermal, optical, and energy-related performance. Additionally, we explore life cycle assessment and techno-economic analysis tools for guiding future research toward environmentally friendly and economically feasible directions for engineered wood products. Finally, this review highlights the current challenges and perspectives on future directions in this research field. By leveraging these new wood-based technologies and analysis tools for the fabrication of carbon-storage materials, it is possible to design sustainable and carbon-negative buildings, which could have a significant impact on mitigating climate change.

“…al., 2023). Most publications seldom take into cognisance the contraryto-fact end-of-life scenarios which may interrupt the smooth functioning of naturally occurring gases, thus interfering with the carbon cycle (Lan et al, 2022). The increasing levels of organic and inorganic wastes in the environment are major sources of global greenhouse gas emissions (Huun, 2020).…”

The predominance of unwanted materials lying fallow in the environment, and the availability of information on waste management, offer the opportunity to explore the use of these resources as sources of recovered material. Regulatory drivers aim to harmonise the recovery potentials of wastes, thereby reducing the volumes sent to landfill. In this vein, this paper investigates the emissions from municipal solid wastes, which can lead to major environmental impacts. This study assessed the influence of recovery efforts on solid waste management practices in Nigeria. This was done by examining available literature chronicling pollution from unregulated dumpsites which can bioaccumulate in the environment, causing climatic impacts. It was discovered that emissions from waste can impact soil, water, and air, thus contributing to greenhouse gas emissions. Many developed countries have recorded significant improvement in adopting treatment facilities that can enable them to meet up sustainable development goals. However, developing countries still need assistance in developing a sustainable waste management programme that can help change their lifestyle, thus improving the management of the waste they produce. It becomes imperative that making the right choices can change the consumption pattern, thus, reducing the influx of pollutants whilst fostering a clean environment. Thus, a high-level recovery of resources can secure a sustainable future and a healthy environment.

“…To address this gap, we develop a framework powered by LCA, Green Chemistry (GC) principles, TEA, and eco-efficiency analysis to identify the pathways of producing greener and lower-cost nanomaterials. In this framework, LCA assesses the life-cycle environmental impacts of a material; [10][11][12] TEA evaluates the economic performance of emerging technologies and various production pathways. 6,13,14 This framework uses the GC principles to develop improvement strategies and scenarios towards greener production.…”
