- Barriers and challenges to waste management hindering the circular economy in Sub-Saharan AfricaPublication . Debrah, Justice Kofi; Teye, Godfred Kwesi; Dinis, Maria Alzira PimentaMore and more, waste generated in most parts of the Western world has been recycled and transformed into new circularity products. However, managing waste within Sub-Saharan Africa (SSA), such as in Ghana, has become a challenge due to the continued practice of the old traditional linear waste economy, that is, the taking, making and disposing methods of management, representing a threat to global environmental sustainability. Despite the need to revise current linear waste management (WM) in order to turn to the circular economy (CE) model, which consists of the concept of renew, remake and share, to advance sustainable development, a number of factors restrict the CE realization in practice, specifically in developing countries. An integrative methodology was used in this article to identify some of the challenges that hinder the achievement of CE in SSA countries. The results revealed the absence of educational programs and public awareness of waste management activities. The findings also highlight the lack of political will, funding and national policies on WM as some of the most significant issues. The study contributes to further encouraging policymakers and policy implementers, entrepreneurs and relevant interested groups to commit resources to sustainable WM services aiming to advancing CE in SSA countries.
- Factors influencing management of dry cell battery waste: a case of Greater Accra Region in GhanaPublication . Debrah, Justice Kofi; Teye, Godfred Kwesi; Dinis, Maria Alzira PimentaIndiscriminate disposal of dry cell battery (DCB) waste contributes to environmental and public health issues in developing countries such as Ghana, due to the toxic nature of this specific waste. Accordingly, a study was conducted in Accra, Ghana, to determine the socio-economic and demographic factors influencing handling DCB waste, aiming a sustainable environment. Using a random sampling technique, a descriptive cross-sectional survey was conducted, encompassing 367 respondents from the Accra-Tema Metropolitan areas and Tema West Municipal Assembly in Greater Accra, Ghana. Using descriptive and multivariate statistical methods, the survey data were analysed with the Statistical Package for Social Sciences (SPSS) version 27. The results of this study show that female gender and residential area are likely to positively influence the use of DCB at home. Education significantly affects the use of DCB and its proper disposal. The results also suggest that 78% of the respondents disposed of DCB waste in waste bins. The mean monthly income of the respondents stands at USD 270, which is average and likely partially to positively influence the disposal of the DCB. The data collected revealed that female gender, age group, family size, and education level influence the indiscriminate disposal of DCB waste and DCB waste recycling. The results highlight that educated females above the age of 55, with a monthly income, are likely to properly segregate DCB waste. This study contributes to the knowledge gap in relation to dry cell battery waste management (DCBWM) in developing countries, aiming to advance global sustainability. This study is expected to contribute to educate and create awareness in managing DCB waste to reduce its indiscriminate disposal which leads to environmental pollution and negatively affects human health and environmental sustainability in Ghana.
- Industrial waste management in Ghana: environmental challenges and climate change impacts on human healthPublication . Debrah, Justice Kofi; Teye, Godfred Kwesi; Wahaj, Zujaja; Dinis, Maria Alzira PimentaWaste having a significant and relevant material presence in our everyday life was not considered worthy of human attention up until the 1990s. Most probably, this delayed recognition of waste is due to the fact that it has been mistakenly understood as something that is supposed to remain invisible to the human eye in a sense that it is assumed to be occupying those spaces that are not inhabited by human beings. Contemporary times, however, are marked by giving due importance to waste. It is seen as a crucial environmental and health challenge for species’ survival on earth and is therefore placed center stage in the United Nations Sustainable Development Goals (SDGs) that aim to protect the planet. More recently, SDG 12, ensuring sustainable consumption and production patterns, has alerted to fast-growing waste management (WM) environmental issues. With the earth being viewed as a limited natural resource and having the inadequate capacity to accommodate wastes leading to adverse environmental and health consequences, caution must be taken to understand the associations between global consumption, total waste, and wasting patterns. Conceptualizing waste as a globally circulating material, particularly in terms of greenhouse gas emissions (GHG) such as carbon dioxide (CO2), methane (CH4), and sulphur oxide (SOx), the governance of waste has become a global concern. This chapter focuses on WM in Ghana, a middle-income economy country in the West of Africa. Due to rapid industrialization, Ghana is witnessing an ever-escalation of the country’s contribution to global environmental waste issues, especially GHG emissions. This study aims to identify and address the challenges associated with managing waste in Ghana. Additionally, it proposes specific measures to mitigate climate change and its effects on the environment and human health resulting from WM. A descriptive cross-sectional study was conducted with 101 responses received from WM experts based on the aim. The data were analysed using the statistical package for social sciences (SPSS) version 27. 72% of respondents were male, with most completing first and second degrees and have been working between 11 and 15 years. Although most of the respondents’ report waste being poorly managed, 93% consider that the associated causes of improper WM include inadequate infrastructure, lack of landfills, lack of tools and logistics, and equipment. All respondents believed that the challenges affect climate change through the emission of GHGs and particulate matter, resulting in global warming and impacting human health.
