The paper presents an overview of some marketing strategies that are strongly influencing on the Nepalese un-plasticized poly vinyl chloride door and windows market. The result of the study reveals that product quality improvement is one of the important products related marketing strategies in the doors and windows market of Nepal and addition of new features. The study also reveals that advertisements and exhibitions/meets are two important promotional strategies influencing the consumers in their purchase. This study followed a judgmental sampling technique. The study shows that there is enough evidence to indicate that the brand preference is dependent on market segment in un-plasticized poly vinyl chloride windows in Kathmandu Valley market. Upon the analysis of the product delivery report of the past five years the market seems to be growing at an average rate of 25% annually. Un-plasticized poly vinyl chloride has comparative advantage over wood and aluminum profiles on technical, physical as well as overall performance comparison hence proving to be a better material for doors and windows.

Nepal has an abundance of biomass resources. Heavy dependence on traditional source and waste management resulting from agricultural waste is one of the major problem in our country. Briquetting from agricultural waste can be an option for resource management. This study was undertaken to investigate the physical and combustion properties of briquettes produced from dried banana tree waste (leaves + pseudostem). Altogether four types of briquettes were produced, two from uncharred biomass using screw extruder and hydraulic jack briquetting machine and other two briquettes were produced from uncharred biomass/charcoal using screw extruder and beehive briquetting machine.For charred briquette, the density of screw extruder briquette (1.06 g/cm3) was higher than hydraulic briquette (0.33 g/cm3). For uncharred briquette, the density was higher (0.72 g/cm3) for screw extruder than beehive briquette (0.44 g/cm3). The Moisture content of briquettes varied from 7.23 to 11.04%, Volatile matter varied from 11 to 68.74%, Ash content varied from 4.94 to 49.43% and fixed carbon content varied from 15.27 to 32.34%. The calorific values of the briquettes ranged from 2462.0827 - 3899.193 kcal/kg, while the thermal efficiency ranges between 24.02– 30.71%, other results shows that the average burning rate between 3.55 and 6.41 g/min. Screw extruder briquette from uncharred Banana tree waste and beehive from charred/carbonized banana tree waste biomass was found to be comparatively better from the present study.
