Leachability of microplastic from different plastic materials.

The use of plastic has become common. Large amounts of plastic waste are disposed in landfill without the ability to biodegrade. These plastic materials often disintegrate into microplastic that end up in the leachate, a wastewater stream containing harmful contaminants extracted from the plastic.

Sustainable Management of Organic Wastes in Sharjah, UAE through Co-Composting.

Daily human activities and vast green areas produce substantial amounts of organic wastes that end up in landfills with minimal treatment. In addition to the problems associated with landfills, disposal through this method is unsustainable in the long run and does not allow recovering materials from the waste. This paper focuses on the co-composting of different organic wastes produced in The Emirate of Sharjah, United Arab Emirates (UAE), to optimize mixing proportions of three different kinds of wastes-sewage sludge (SS), green waste (GW), and food waste (FW).
