Bioplastics are becoming more and more widespread as substitutes for petroleum-derived plastics due to their biodegradability. Bioplastics degradation under different environments has been described and reported to depend mainly on bioplastics' compositions and the environmental conditions. Incomplete degradation during waste management processes and leakage of bioplastics into the environment are becoming major concerns that need to be further investigated. In this context, the present paper aimed to review recent literature dealing with biodegradation of bioplastics under industrial (e.g. anaerobic digestion and composting) and natural (e.g. soil and water) environments, and to link it to the potential bioplastics' leakage into the environment. Reviewed data were used to estimate the potential role of waste management processes in decreasing the potential leakage of bioplastics. Depending on bioplastics' type and processing conditions, waste management can effectively reduce bioplastics' potential leakage, decreasing the concentration of these materials that can reach the natural environments.

Background: In developing countries, due to improper management of domestic animals' exposures, under-five (U5) children have been affected by diarrhoea. However, there is no evidence that shows the presence of diarrhoea-causing pathogens in the faeces of U5 children and animals residing in the same houses in the Sidama region, Ethiopia.
Methods: A laboratory-based matched case-control study was conducted on children aged 6-48 months in the Sidama region of Ethiopia from February to June 2023.

This study examines the Waste Kuznets Curve (WKC) hypothesis by integrating it with the Tapio decoupling model to explore the relationship between economic development and e-waste imports in 45 emerging economies from 2002 to 2022. The empirical results show that (1) the relationship between economic growth and e-waste imports exhibits an inverted U-shaped curve, with decoupling achieved when GDP per capita exceeds the WKC turning point of $10,755.23; (2) Emerging economies are categorized into six quadrants based on their e-waste decoupling status: high-income non-decoupling, low-income non-decoupling, low-income relative decoupling, high-income relative decoupling, low-income absolute decoupling, and high-income absolute decoupling; (3) Most emerging economies remain in low-income non-decoupling state, with only a few countries like China and Poland achieving high-income absolute decoupling.

According to the Food and Agriculture Organization of the United Nations (FAO) more than 14% of the world's food production is lost every year before reaching retail, and another 17% is lost during the retail stage. The use of the expiration date as the main estimator of the life-end of food products creates unjustified food waste. Sensors capable of quantifying the effective food freshness and quality could substantially reduce food waste and enable more effective management of the food chain.
