Mineral exploitation and mining are expanding with increasing industrialization, and as exploitation increases, so will their enormous environmental impact. The biological technique was found to be a suitable alternative for treating mine wastes and recovering toxic heavy metals. Acid Mine Drainage (AMD) or Acid Rock Drainage (ARD) is the most wellknown mining waste laden with heavy metals that remains untreated. Microorganisms help in detoxification and thereby facilitate the extraction of pollutants from mine waste. Sulfate Reducing Bacteria (SRB), among all known microorganisms, play an important role in mine waste treatment by neutralizing acidity and reviving alkalinity. The use of microorganisms in treating overburden dumps helps reduce the amount of waste, augment natural resources via metal recovery, and maintain a healthy environment. Such a technique picks up momentum due to its low cost, easy availability of ingredients, and eco-friendly nature. Such a treatment system may or may not be capable of removing toxicity. Therefore, it is advisable to use the same along with other techniques depending upon site conditions, the nature of the deposit, and the availability of essential requisites. This paper attempted to highlight potential thrust areas requiring this technique as well as limiting factors.
This article provides a summary of the strategies currently in use to extract energy from municipal solid waste. Special trash is ignored since its characteristics greatly vary from type to type and from region to region. However, municipal solid waste has properties that make it amenable to a more standardized investigation of its energy potential. The initial part examines the methods for extracting usable energy from garbage. The second part discusses energy availability in the context of the changing qualitative and quantitative characteristics of Municipal Solid Waste (MSW). The third section takes a look at selective collection and how it serves the larger goal of energy recovery. In the fourth part, the significance of Directive 1999/31/CE and its effect on energy recovery strategies are discussed in the context of the current trend in the use of residual municipal solid waste. A mandatory pre-treatment makes less interesting the option of landfilling, moving the energy exploitation of residual municipal solid waste towards thermal treatments. Also, research shows how thermal treatments and anaerobic digestion could work together to provide for a local resident's energy needs.
The oil production and water cut prediction is one of the most interesting research area of the reservoir production performance analysis. In this research, the focus was to use the growth curve method, and the main reason behind selecting this particular method is that it has the advantages of the general water drive curve method. Also, the fast and simple calculation with fewer parameters and the combined solution model method, widely used in production prediction, are two advantages. There are two growth curves, i.e., 4W and 4Y4, and based on the analysis of these two model growth curves, a new generalized growth curve has been proposed for the well production performance. A new model will be developed that should be efficient and feasible in predicting cumulative oil production, annual oil production, and water cut at different oilfield development periods. So, this research will use software, a Matrix Laboratory (MATLAB) programme will be developed to derive the parameters of the new model that is to be proposed in this work. Two oil fields will be chosen for the test case of our new model to check its vitality when it is applied to the production data of the Samattalol and Daqing oilfields situated in China. The new model will predict the cumulative oil production, annual oil production, and water cut closer to the actual production data, and satisfactory results will be obtained according to our hope, which would showcase the reliability and practicability of the new model.
Globally, agriculture is frequently impacted by climate change. Choosing the optimum cropping system and related farming techniques is crucial to implementing an agricultural production system that is both economical and environmentally friendly. One of the main agricultural systems and industries in the nation that has the potential to significantly sequester CO2 is coconut farming and the coconut agro-ecosystem. Only one state produces 2.11, 3.10, and 3.96 tons per acre per year, which is Tamil Nadu. In Vellore district, coconut trees aged five, ten, fifteen, twenty, and twenty-five could sequester 1.48, 1.37, 1.78, 2.42, and 4.63 tons per acre per 365 days, respectively. The C-capture potential of a 10-year- old tall or dwarf coconut tree was roughly 18 to 28 kilograms per tree per year. The Vellore district's tall and dwarf coconut plantations, which spanned fifteen years from 2003–2004 to 2017–18, removed 1.15 million tons of carbon dioxide from the environment. This research mainly contributes to the utilization of carbon in increasing yield of coconut trees.
The desalination process is used to reduce the salinity of water to meet the water demand in water-scarce regions. There are several methods available for water desalination, each with merits and demerits in terms of raw water treatment, process operations, and water quality management. In the present analysis, a systematic review of various desalination processes is presented based on technical, economic, and environmental analyses. Thermal and Reverse Osmosis (RO) processes are widely studied in the literature and used for Sea Water (SW) desalination on a larger scale to produce drinking water. The technical and economic criteria are used to show that Seawater Reverse Osmosis (SWRO) technology is better when compared to other desalination technologies.
The energy that's generated by the moving wind is named as "wind energy." It's abundantly available within nature. In India, grid-connected wind power generation has now gained a high level of attention and acceptability as compared to other renewable technologies available in the country. Many developed and developing countries are now captivated by wind energy to fulfil many important aspects such as irrigation and electricity generation in remote areas. It's a clean source of energy, which has upmost importance within the growing rate of industrialization, agricultural development, etc. India has the fifth-largest installed alternative energy capacity. India has about 7% alternative energy installations, and about 2–3% of the whole energy generation is from wind. This paper will describe India's wind generation potential as well as the global status of wind energy. The objective of this study is to look at the present developments that have been made in India in the field of renewable energy and to analyze the future of our country in this world.
