“…This increase is attributed to the introduction of various MSW valorization streams throughout the scenarios. Many researchers have found that the less amount of MSW is landfilled, due to MSW treatment activities’ introduction, the less negative environmental impact is observed [ 46 , 47 , [55] , [56] , [57] ]. In this study, landfill diversion rates increase because the burden on the landfilling decreases.…”

“…In Nottingham (England), for example, results from LCA indicated an improvement in greenhouse gas reduction while improving waste collection, treatment, and material recycling [ 55 ]. Furthermore, in Arusha (Tanzania), LCA results revealed that a combination of recycling, composting, and landfill performed better in alleviating environmental impacts [ 56 ]. This underlines the importance of conducting such studies in the waste management sector to induce evidence-based decision-making and efficiently contribute to improving the MSW field.…”

“…Another interesting work of Richard et al [ 21 ] investigated the economic cost and environmental burdens in municipal solid wastes (MSW) management. Compared to the other scenarios, one of the solutions, which is a combination of recycling, composting, and landfilling, had the lowest economic cost and environmental impact in most categories.…”

Life Cycle Assessment (LCA) of Particleboard: Investigation of the Environmental Parameters

Particleboard is not entirely a wood replacement but a particular material with its properties, making it more effective at different times than heavy or solid wood. The world’s biggest concern is environmental problems with formaldehyde as a particulate board binder that can lead to human carcinogenic agents. A cradle-to-gate life cycle assessment (LCA) of particleboard production was performed using openLCA software. The impact assessment was carried out according to the software’s features. This preliminary investigation aims to analyze the chemical composition of particleboard and identify its environmental impact. The Fourier-transform infrared spectroscopy (FTIR) system was used to track the functional group of aliphatic hydrocarbons, inorganic phosphates, and main aliphatic alcohols found in particleboards made in Malaysia. Based on the FTIR results, aliphatic groups were found in numerous aggravates that the spectroscopic infrared was likely to experience. The most important vibrational modes were C–H, at approximately 3000 cm−1, and –CH deformations around 1460 cm−1 and 1380 cm−1. Eight effect groups demonstrated that 100% of the input and all analyses produced the same relative outcome. The life cycle of a product is determined by pollution of the air, water, and soil. Thus, particleboard has a minimal impact on the environment, except for global warming.

Life cycle assessment (LCA) is a vital tool for evaluating the environmental burden of solid waste. This study investigated the outcomes of selected studies that applied the LCA methodology in assessing the environmental consequences of solid waste management (SWM) systems in Africa. Thirteen process-based LCA studies on SWM were reviewed, drawing from established criteria in databases such as SCOPUS, Elsevier, and Google Scholar. These studies were distributed across various African countries, with three conducted in Mauritius and Nigeria each, two in Zimbabwe and South Africa each, and one in Tanzania, Ghana, and Uganda, respectively. The evaluated parameters included aspects such as goal and scope, functional unit, system boundary, impact assessment categories, and sensitivity analysis. The findings revealed that majority of the studies employed similar waste management scenarios to determine the most environment-friendly, yet they differed considerably in some parameters. Climate change and global warming were the most assessed impact categories. Municipal solid waste (MSW) and plastic waste were the leading waste categories. MSW typically comprises paper, bottles, metal, plastics, glass, organics, and mixed waste proportions. The study also stated that the lack of reliable data on solid waste was a significant challenge faced by African countries in LCA studies. The paper’s findings highlighted that a significant number of the studies, particularly in Nigeria, did not incorporate sensitivity analysis into their assessments, a crucial component for result interpretation. Consequently, the study emphasizes the importance of conducting more LCA research studies in African countries to produce pertinent data on SWM.
