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 of Mingora Khuwarr is further recommended for treatment before its discharge into the main River.

The use of herbal medicines in the recent years has tremendously increased due to their lesser side effects and acceptability to a majority of population. These herbal medicines have been used for thousand of years by Asian people for the remedy of many diseases. Currently increased scientific interest and consumer demand for alternative therapies have promoted the development of herbal products is dietary supplements for health outcome. Plant based medicaments have been man's prime therapeutic weapons to rescues him from diseases. As nutrients (both macro and micro) play a vital role to assess the medicinal value of a plant and therapy in health and disease. Theses nutrients are essential in sufficient quantities for nutritional, enzymatic reactions and metabolic processes.

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 for maximum conversion into oil for a variety of catalysts.

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 atmospheric pressure. The objective of the present study was to convert waste plastic and used tyres catalytically at relatively low temperature as well as to derive oil in the boiling range of commercial fuel oil.
