- Environmental waste sustainability: organic valorisation and socioeconomic benefits towards sustainable development in GhanaPublication . Debrah, Justice; Vidal, Diogo Guedes; Dinis, Maria Alzira PimentaEnvironmental waste sustainability is a challenge in Africa, and specifically in Ghana. The absence of adequate facilities and infrastructure for sustainable waste management in metropolitan, municipal, and district assemblies (MMDAs) in Ghana has led to negative and unsupervised environmental impacts of all types. This study aims to assess the organic waste generated and the ecological impacts of organic fertilizer and energy production for the Ashaiman community, Ghana. The analysis of this research focuses on how the organic waste collected in this location is treated in an anaerobic digester to produce organic fertilizer, wastewater irrigation, and biogas for electricity purposes, contributing to this community’s socioeconomic benefit. Safi Sana company role in the community is presented as an example. The production of waste generated in the community leads to better development for a clean and sustainable environment. This alternative is as an acceptable way to face the challenges associated with the Sustainable Development Goal (SDG) 6 of the UN 2030 Agenda and its interconnections among the other SDGs.
- Sustainable pharmaceutical waste management: pharmacist and patient perception in ghanaian hospitalsPublication . Debrah, Justice; Vidal, Diogo Guedes; Dinis, Maria Alzira PimentaPharmaceutical waste (PW) is known to be a health problem in developing countries, being harmful to human beings, animals, and the environment, with a high potential for the transmissibility of diseases. This study aims to address the implementation of strategies in the hospital context in Ghana, Africa, regarding the proper pharmaceutical waste management and the relationship with the environment and public health from both pharmacists and patients. Based on a questionnaire and observation, a cross-sectional exploratory-descriptive study with quantitative and qualitative approaches (mixed method) was carried out in selected hospitals in Ghana. A total of 111 responses were received, with 23 (76.7% rate response) being the professional pharmacists and 88 (60.7% rate response) from patients. The survey used random sampling, and the data collected were analyzed using SPSS version 27. The result shows that most of the participants were aware of what constitutes PW and had social awareness of PW. The majority of both types of respondents do not segregate PW, resulting in poor disposal. Unsegregated PW from the professionals was due to a lack of logistics like color-coding. The problems associated with PW in Ghana will be better managed through continued education and awareness at all levels to promote waste segregation.
