Polycyclic aromatic hydrocarbons (PAHs) are common and persistent environmental pollutants produced during the incomplete combustion of fuels. They are known for their carcinogenic and mutagenic properties. Thus, their removal from water bodies is highly crucial and has become a critical issue globally. As a solution, here an electrospun polycaprolactone (PCL) membrane with a mean fiber diameter of 2.74 ± 1.3 μm was produced by electrospinning. Water contact angle (WCA) analysis confirmed the hydrophobic nature of the PCL membrane with a WCA of 124°, which remained stable over time.

A dynamic growth model (CO2FIX) has been used for estimating the Carbon Sequestration Potential of Kafal (Myrica esculenta), an indigenous multipurpose tree used for timber, fuel wood, fiber and in addition to its medicinal value. The present study has been carried out in the campus of V.C.S.G. College of Horticulture, U.U.H.F., Bharsar, Pauri Garhwal, Uttarakhand. The altitude of the location is ranging from longitude 78.59’:20.28’E, latitude 79.00’:30.05’N and 2000 m MSL altitude. The temperature and rainfall of this hilly area ranged from -4.0 to 28.

Women of Rajasthan has to perform agricultural practices and contribute a major share of family economy in terms of food grains, oilseeds, vegetables, fruits, milk, wool, fuel, fiber, timber etc. The average sex ratio of the region is low. The literacy status of the women is also lower than their male counterpart. The participation of women in the tertiary sector such as medical, teaching, administrative and other official services is lower than the male population.

During the last 4-5 decades of agricultural research and development in India, major emphasis has been given to component and commodity based research projects for developing crop varieties, animal breeds and farm implements etc, mostly conducted in isolation and at the institute level. This component, commodity and discipline based research has proved largely inadequate in addressing the multifarious problems of small farmers.

With the increasing amount of waste generation from different processes, there has been a growing interest in the use of waste in producing sustainable building materials to achieve potential benefits. This study investigated the influence of waste polypropylene carpet fibers and palm oil fuel ash (POFA) on the microstructure and residual properties of concrete composites exposed to elevated temperatures. Four mixes containing carpet fibers (0% and 0.5%) and POFA (0% and 20%) were prepared. The specimens were exposed to high temperatures (200, 400, 600 and 800 C) for 1 h.

Whether to co-process alternative fuels in cement kilns can be evaluated upon environmental and economic criteria. As is discussed in detail below, the potential benefits of burning alternative fuels at cement plants are numerous. However, the contrary is possible, when poor planning results in projects where cement kilns have higher emissions, or where alternative fuels are not put to their highest value use. Five guiding principles outlined by the German development agency, GTZ, and Holcim Group Support Ltd.

Inventions in steam engines, cotton mills, and iron works converged in the eighteenth century to propel the First Industrial Revolution. Inventions in internal combustion engines, electrification, and steelmaking in the nineteenth century ushered in the Second Industrial Revolution. Today, twentieth-century inventions in digital technology are being conjoined with twenty-first-century innovations in software, materials and advanced manufacturing processes, robotics, and web-based services to inaugurate the Third Industrial Revolution.

Soil fertility is critical for the provision of adequate food, fiber and renewable natural resources(fuel,wood etc.). In the developing world soil fertility is linked to economic well being of many farm families. Poor soils means poor harvest leading to low returns for the over 60% of the population of developing countries relying on agriculture for survival.Use of inorganic and organic fertilizers in addition to biological processes to improve the fertility of the soil requires good understanding of their practical use and management.

Soil fertility describes soil nutrient status and the factors controlling the supply of nutrients to plants. Continued efforts to improve soil fertility are required to support the world's growing demand for food, fiber, and renewable fuels. Important ecological services provided by soils, such as biodiversity, buffering capacity, and nutrient recycling benefit from the amendments applied to sustain soil fertility. Those amendments need to be applied in a manner that is both economical and practical for the producer to achieve agronomic objectives that are environmentally sound.

On the other hand, salinity affects 7-9 % of the world’s land area (Szabolcs, 1994), and the area is increasing (Ghassemi et al., 1995). Nowadays, one of the major technological goals of the energy production is the replacement of the fossil-based fuel for biofuel, mainly due to environmental issues. Bearing that in mind, it is mandatory to investigate the effect of water deficit and salinity stress in plant species with high potential for application in large scale production of nonfossil based fuels....

Of course, biomass and food brought this key trade-off biomass use: the controversial food or fuel. With two primary uses of biomass appropriate resolution of this balance is essential for biomass acceptable and beneficial use in the future. Obvious example of biomass for energy is ethanol misuse produced from corn, a conversion process is relatively inefficient as well as a direct Collision course with the way corn as food.

Petroleum products are everywhere around us. They appear in visible forms, such as gasoline, diesel, kerosene, and aircraft fuels, and in less visible forms over the entire spectrum of industry, such as automobile lubricants, greases, carbon black for truck tires, bitumen for road building, the waterproofing in house roofs, feedstock for petrochemicals, synthetic fibers, and plastics. Petroleum feedstock is used in the manufacture of white mineral oils in eye ointment, hair oils, cosmetics, petroleum solvents, and pest control sprays....
