Water samples were collected from different localities of Mingora Swat, Pakistan and were analyzed for both physical and chemical parameters. The results show that the sample area is moderately polluted and the source of pollution is the municipal sewage of the local community located around the Mingora Khuwarr. The water of Mingora Khuwarr then joins the main Swat River which is a main source of drinking and irrigation for the lower Swat. However due to dilution factor the concentration of pollutant further decreases in the bulk water and thus its toxicity also decreases. However the water...

Butyl inner tubes are used as inner tubes and inner liners in tubeless tyres. After some time it is disposed as waste because its efficiency has become reduced. Proper disposal or beneficiation of waste inner butyl tubes are of the great concern, both environmentally and for resources conservation. An environmentally friendly method for conversion of used isobutyl isoprene rubber inner butyl tube into useful products has been investigated. The method is based on catalytic cracking using batch type reactor. Optimum conditions like temperature, catalyst weight and reaction time were optimized...

Catalytic pyrolysis has the potential of transforming used plastic and tyres into useful chemicals. Used plastic and Scrap tyres represent a major environmental problem. Catalytic Pyrolysis is an environmentally friendly process to transform used polymers into useful products likes gas, oil and pyrolytic carbon black. Tyre recycling has become a necessity because of the huge piles of tyres that represent a threat to the environment. The used tyres represent a source of energy and valuable chemical products. Waste tyres & plastic were pyrolysed catalytically in a batch reactor under...
