This article takes us into the world of municipal solid waste entrepreneurs, revealing how public awareness campaigns and behavioural change efforts intertwine with entrepreneurial endeavours. Through conversations with 11 key participants-entrepreneurs from four geopolitical zones of Nigeria and a senior management figure from the Lagos State Waste Management Authority-I hear firsthand accounts of the challenges they face and their strategies to transform waste into opportunity. Guided by the theory of planned behaviour, this study sheds light on how these entrepreneurs perceive the role of public awareness in shaping waste management behaviour and driving business innovation. From their stories, a common theme emerges: the need to educate the public about responsible waste practices while developing creative business models that engage communities. Concepts like "freemium-to-premium" offerings are explored as ways to break through psychological barriers and inspire wider participation in waste management initiatives. These voices illustrate how awareness campaigns are not only about fostering environmental responsibility, but also about creating pathways for entrepreneurial growth, ultimately contributing to a more sustainable and circular economy. This study contends that public awareness extends beyond mere knowledge; it acts as a form of infrastructure in its own right. Rather than being just an end goal, awareness becomes a vital foundation in the pursuit of improved waste management practices, serving as a key driver for meaningful environmental action.

In recent years, coffee capsule waste has been generated on an increasingly large scale worldwide, but disposing of it in an environmentally sustainable and economical manner still poses major challenges. This work maps the original scientific production focused on the valorization of coffee capsule waste through a bibliometric review based on scientific articles published in the last 10 years (from 2014 to 2024) in the Scopus database. The review identified different ways of valuing coffee capsule waste, including the development of composite materials, composting, energy production, jewelry and decorative items, and the construction of supercapacitors and sensors.

One of the challenges encountered in mining is acid mine drainage (AMD) in sulphurous ores in response to rainfall and groundwater. CPB one of the most prevalent waste management systems addresses this issue today. Nevertheless, in the long term, the concretion in CPB may become ineffective because of external factors, such as groundwater and rainfall.

Microplastics (MPs) are emerging pollutants that pose significant risks to ecosystems due to their inherent toxicity, capacity to accumulate various pollutants, and potential for synergistic impacts. Given these concerns, the focus of this research is on the critical need for effective MPs removal from aquatic environments. Using BBD method, this study aimed to identify the key parameters affecting the removal of MPs by algal biomass from aqueous solutions.

We conducted surveys of Mediterranean beaches in Egypt, Morocco, and Tunisia including 37 macro-litter (> 25 mm) and 41 meso-litter (5-25 mm) assessments. Our study identified key litter items and assessed pollution sources on urban, semi-urban, tourist, and semi-rural beaches. Macro-litter concentration averaged 5032 ± 4919 pieces per 100 m or 1.
