Knitting industry is one of the flourishing business in India in recent times. This knitting industry provides huge collection of knitted fabrics in different forms and styles. Apart from the fabrics they also provide employment to lot of people. A drastic problem in this industry is the fibre fly generation. These fibre fly are generated in the knitting machine from cotton yarns in different zones of the knitting machine which may be due to friction, yarn breakage and bending of yarns at the needles, sinkers, guides and other regions. They may also be produced due to rotational movement of yarn in the cone unwinding and guiding zone, vibrations during the movement of yarns and friction occurring due to interaction between yarns. At present these fibre fly are removed by using large blowers in large scale industry. These blowers are not affordable in small scale industries due to the cost of blower, power consumption after installation, etc... People exposed to these fibre fly may suffer from serious diseases which may have acute and chronic symptoms. This is a serious problem which can be overcomed by using the dust (fibre fly) collector. It can be used by all types of knitting industry and also removes maximum dust produced. This paper is about the dust collector in knitting Industry. This paper briefly discusses about the technique used in the fibre fly collector for removing the dust in knitting industry and how to avoid the risk of air pollution and effect of fibre fly.

To evaluate CO2 emission mitigation potential and cost effectiveness of rice husk utilization, Life Cycle Analysis was conducted for 9 scenarios. The results showed that, gasification is the most efficient CO2 mitigation. From cost analysis, the cost mitigation can be achieved by replacing the current fossil fuels in cooking scenarios. Among the power generation scenarios, it was found that 30MW combustion and 5MW gasification power generations were the most economically-efficient scenarios. The briquette combustion power generation appeared less cost-competitive than direct combustion, whilst the large-scale gasification scenarios and the pyrolysis scenarios give the increase in cost from the baseline. From the viewpoints of both CO2 and cost, it was indicated that the win-win scenarios can be the rice husk use for cooking, for large-scale combustion power generation, and for small-scale gasification. Để đánh giá tiềm năng giảm thiểu phát thải CO2 và hiệu quả chi phí của việc sử dụng trấu, phương pháp đánh giá vòng đời sản phẩm đã được thực hiện cho 9 kịch bản. Kết quả cho thấy, khí hóa trấu để sản xuất điện có tiềm năng giảm phát sinh khí CO2 nhiều nhất. Kết quả phân tích chi phí cho thấy việc giảm thiểu chi phí có thể đạt được khi thay thế sử dụng nhiên liệu hóa thạch trong kịch bản dùng trấu cho nấu ăn.

In this study a new method of locating culverts is presented with the composition of achieved discharge from hydrological analysis and simulated forest roads in RoadEng 3D simulator to improve drainage condition. Locating culverts was performed on a small scale (1:20 000, using GIS) and large scale (1:2 000, road geometric design simulator). The small-scale study regarding the achieved discharge from streams shows that the installation of some culverts is not necessary. The large-scale study also showed that the geometric design of forest road has a significant effect on locating culverts and its accuracy. To improve drainage conditions 6 culverts and 2 waterfronts taking into account the geometric design of forest road, hydrological conditions and appropriate intervals (155 m) have been proposed. No installation or lack of accuracy to find the best location of culverts may result in the occurrence of creep and landslide, so the cost of destruction would be several times higher than the cost of technical buildings construction.

Critical Overview

This chapter provides a critical overview of urban air pollution and traffic congestion in India. It discusses temporal and spatial variations in the level of urban air pollution and traffic congestion in the country and challenges posed by them. India loses about 2 per cent of its GDP because of urban air pollution. Urbanization of small-scale industries and increasing demand for private vehicles are major determinants of urban air pollution and traffic congestion. Legitimacy in enforcement of polices is a strong predictor of success of a policy. Growing demand for green cities coupled with transparency in governance will reduce frictions arising from pollution and congestion.

Nigeria is one of developing countries in the world that experience shortage of electricity for her economic and social development. In Nigeria, most of the small-scale industries use diesel/petrol-based systems to generate their electricity. However, due to the cost fluctuation of oil and gas fuel, an alternative power generation should be considered. This paper targets to examine the cost analysis of system for supplying electricity to LUMATEC Aluminium products shop in Mubi, Adamawa state Nigeria. Hybrid Optimization Model for Electric Renewable (HOMER) is used as a tool for cost analysis. The scenario consider in this study was only stand-alone with battery system. Results revealed that the system have 10kW PV with cost of electricity (COE) of $0.312/kW. The initial capital cost and total net present cost (NPC) are $21.775 and $26.148 respectively, with payback period of 5.8years. In conclusion, this study provides the solution of power supply to the small-scale industries at cost effective and available throughout the year and it is feasible to solve the small-scale industries, rural and urban electricity supplying in this country (Nigeria). It is recommended that Nigerian Government & Law makers should promotes the use of standalone PV system for domestic and small-scale industry by providing financial assistance through soft loans, subsides and grants.
