Waste accumulation is reported to be one of the serious environmental problems. Organic wastes such as organic fraction of municipal solid waste (OFMSW) or sewage sludge (SS) can be treated using aerobic microbial decomposition called composting. It is important to know when composts obtained in co-treatment processes turns to be safe but not toxic for the environment. In this study, we estimat...

Thermal plasma vitrification is a successfully used technology to treat and recycle hazardous wastes. High plasma temperatures enable to destroy complex molecules and to encapsulate the toxic elements in a non-leaching glass or ceramic matrix, obtaining nonhazardous wastes with large volume reductions. In this work, hazardous incinerator residues (bottom and fly ashes) have been treated by mean...

Aquaculture is the fastest growing food-producing sector accounting for almost 43% of the world’s food fish. There is however a need to increase aquaculture production in the next two decades in order to satisfy the minimum protein requirement for human nutrition. There are many constraints that limit the maximum production in aquaculture systems such as water quality and adequate live feeds. W...

Citrus is a major processed crop that results in large quantities of wastes and by-products rich in various bioactive compounds such as pectins, water soluble and insoluble antioxidants and essential oils. While some of those wastes are currently valorised by various technologies (yet most are discarded or used for feed), effective, non-toxic and profitable extraction strategies could further s...

Hazardous solid wastes may pose a serious risk to human health and to the environment, if not managed appropriately and disposed of safely. In this study, the effective stabilization of tannery sludge, a toxic industrial solid waste produced from the physico-chemical treatment of tannery wastewaters, was examined by the addition of ladle furnace slag (LFS), another industrial solid waste. Moreo...

With rapid industrial development, problems related to pollution are becoming severe Water pollution is one of the most serious problems because inorganic and organic wastes are discharged to the aquatic environment either in water soluble or insoluble forms. Heavy metal ions have lethal effects on all forms of life and these enter the food chain through the disposal of wastes in water channels...

Arsenic (As) is a toxic trace element with many sources, including hydrocarbons such as oil, natural gas, oil sands, and oil- gas-bearing shales. from these hydrocarbon sources can be released to the environment through human activities of production, storage, transportation use. In addition, accidental release aquifers naturally occurring (geogenic) As induce mobilization groundwater biogeoche...

The World Health Organization (WHO) has declared the novel Covid-19 pandemic currently ravaging world as a global mishap due to its wide-spreading across different nations. As number of confirmed cases continues increase daily, there will be great need for delivery pharmaceutical palliatives developing nations them manage situation. Most supplies used in many countries such test kits and protec...

Mishandling of hazardous wastes, like their unauthorized disposal in abandoned dump yards or sites, in river beds, estuaries or in the sea, causes substantial damage to the environment and its resources and, given the persistence and toxicity of these pollutants, they can seriously damage human health and quality of life. The importance of controlling management, transport, and disposal of toxi...
