Despite rapid population growth, urbanization, and economic development in Bangladesh, there is a lack of evidence to measure the impact of dumpsites on human health and the environment. This study sought to assess the health impact of temporary disposal sites in Khulna city on residents living nearby. Data was collected through self-administered questionnaire surveys surrounding the dumpsite areas. Altogether 180 households were surveyed by random sampling approach from >50 m (close to the dumpsites, CD) and 50-300 m radius (away from the dumpsites, AD) of the dumpsite. The participants were mostly employed with low income (

As the demand for sustainable energy sources intensifies, biodiesel emerges as a compelling renewable alternative to petroleum-based fuels. Leveraging waste cooking oil (WCO) as a feedstock not only offers an environmentally friendly fuel source but also addresses waste disposal issues. However, biodiesel production from WCO faces challenges, particularly due to its high free fatty acid (FFA) content, which can hinder efficient conversion and lead to soap formation in traditional alkaline-catalysed processes.

The complex composition of real plastic wastes poses a significant challenge for their large-scale disposal. A responsive on-site compositional analysis of plastics is informative in choosing downstream processing methods. Nanocatalyst-based assay kit is highly qualified for this scene; however, there remain no efficient nanocatalysts for plastics due to their highly inert chemistry.

Coal fly ash (CFA) is a predominant waste by-product of coal combustion which is disposed of in open ash dams that utilize large pieces of land. This waste material is classified as a hazardous substance in South Africa as well as in other countries due to its fine particles that are easily blown to the atmosphere and the unacceptable levels of heavy metals and persistent organic pollutants. Contaminants in CFA can pollute surface and ground water, agricultural sites, soil and therefore pose risks to the health of humans and the environment.
