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.
