Abstract:-Sphagnum culturing refers to the cultivation of Sphagnum mosses to synthesize Sphagnum bio mass sustainably. Peat land or wet land are the regions in which biomass can be sustainably produced. This paper discusses about the different aspects of sphagnum cultivation and its biomass production.

Abstract:-Biodynamic farms and gardens mainly mimic the biodiversity of natural ecosystems, amplifying the health and resilience of the farm organism. Annual and perennial vegetables, herbs, flowers, berries, fruits, nuts, grains, pasture, forage, native plants, and pollinator hedgerows can very much contribute to plant diversity. Diversity in livestock is much beneficial, as each animal species brings a different relationship to the land and unique quality of manure. The diversity of plant and animal life can be mainly developed over time, starting with a few primary crops and one or two species of livestock (even as small as earthworms or honeybees), and adding more species as the farm organism matures.

Abstract: According to The IAEA International Nuclear Event Scale (INES) the most devastating (INES Level-7) nuclear accident occurred at Chernobyl Nuclear power plant (NPP),USSR (April 26, 1986) and Fukushima Daiichi NPP, japan, (March 11, 2011) which has causes a great damages on life’s, properties and more importantly it convulses people trust on nuclear energy. Radiological impact from these two nuclear accidents is analyzed in this study. Atmospheric release of radionuclides and maximum radionuclides concentrations in air, rain water, biological material, drink water (tap water) and soil were observed based on distance and continent from the NPPs after the Chernobyl and Fukushima Nuclear power plant Accident. Most of the radioactivity releases from both accidents were noble gases, iodine, cesium, and tellurium.  The amount of refractory elements emitted from the Fukushima accident was approximately four orders lower in magnitude than the Chernobyl accident. After comparison on various issues how the laws and regulation have modified or changed (in some cases) by IAEA and other legislator organization including respective government are also observed. The main purpose of this paper is to analyze the lessons learn, implement the changes and abide by the guidelines to other currently used and under construction power plants. It must have to do to increase their safety and minimize the risk of future catastrophes. Finally our inherent objective is as Bangladesh is a newly emerged country in nuclear energy sector, lesson from these two power plant accident might help to remain more careful and keep surveillance on every sector including operation and maintenance of the plant to increase its safety and become a successful nuclear plant operating country.

Abstract: Agriculture plays vital role in the development of agricultural country. Agriculture has been one of the primary occupations of man since early civilizations and even today manual interventions in farming are inevitable. In our country, as they can be used to grow plants under controlled climatic parameters which directly or indirectly govern the plant growth and hence they produce.. Greenhouse agriculture needs to control the environmental factors to obtain the optimum growth conditions for the crop. Currently, artificial management is the major way to detect and control the environment factors, wastes lots of manpower and relatively large of monitoring error, affecting the growth of crops. To achieve the intelligent monitoring of greenhouse environment parameters like temperature, humidity, soil moisture and light intensity and keeping the user continuously informed of the conditions inside the greenhouse using IoT technology.

Abstract: Recently, there's associate increasing concern regarding the atmosphere. The requirement to come up with pollution-free energy has triggered considerable effort toward renewable energy (RE). RE sources like star, wind, flowing water and biomass supply the promise of unpolluted and plenteous energy. once energy is generated through renewable sources like star, wind, energy there's a necessity to enhance power quality and scale back harmonics thus we tend to develop the active power filter that is a complicated power device, which may be used for compensating harmonics and up power quality. the various forms of active power filters are: shunt active power, series active power and hybrid active power filters. Among the 3 sorts, the shunt active power filter injects an acceptable compensating current at purpose of common coupling so the harmonics gift within the line square measure off out and therefore the curved nature of voltage and current waveforms ar remodeled. A PI managementler primarily based control algorithmic rule is developed to manage the 3 section shunt active power filter to compensate harmonics created by the nonlinear load to enhance power quality. The fast p-q theory is employed for extracting the harmonic current. conjointly a PI controller is developed to take care of a relentless DC voltage across the capacitance of DC bus aspect of the electrical converter. The 3 section shunt active power is developed by victimisation turbine. The projected shunt active power will suppress harmonics generated by the non liner load and it will maintain the doctorate value inside the quality limit.

Abstract: E- Waste or electronic waste refers to all waste formed by electronic devices such as computer, laptop, refrigerator, Smartphone etc. All these are discarded by the owner & thrown as waste. E- Waste causes E-pollution. There are many harmful materials like lead, barium. It can be prevented by 3R (reduce, reuse, recycle). Recycling is a process where equipment is reverted to a raw material form. Part of this evolution has involved greater diversion of electronic waste from energy-intensive down-cycling processes (e.g., conventional recycling), This recycling is done by sorting, dismantling, and recovery of valuable materials. The environmental and social benefits of reuse include diminished demand for new products and virgin raw materials many company offer recycling of their product nowadays. This business is developing rapidly on large scale. The aim of this concept review paper is to study, analyse, discuss existing Ewaste recycling methodologies and conceptualize and propose some new approaches for recycling 100% of e-waste.

Abstract: Our goal for this project is to design and implement a pedaling chair power generator for the rural areas are having the common problem of hardly any resource to power up their devices due to backwardness. The “Pedal Operated Power Generator†is an initiative to bring safe and reliable power to the billions of people around the world without electricity. This goal will be accomplished by designing a safe and sturdy human powered stationary pedaling chair that produces DC energy. The DC power generated can be stored via batteries and used by the local population to use for lights and other utilities that many take for granted on a daily basis. Pedaling chair Power Generators are not a new idea, with many created by hobbyist for residential use with small scale energy in mind, to charge batteries in case of a power outage or natural disaster. We are looking to expand upon these designs and build a DC generator that will convert human power into electrical power. The objective is to build a device that is safer and more power efficient. If our product design were to be built and shipped to people across the globe, it would be imperative that it meets all the safety specifications that any national commercial product entails.

Abstract: With the rapid increase in technology, as new industries develop, as new technologies emerges, the exposure of chemicals in the environment is greatly increasing the risk of the people’s life in the society. Despite their benefits, chemicals may, especially when misused, cause adverse effects on human health and environmental integrity. And whenever there is some eruption in the chemical tanks due to any Natural Hazards or Human mistakes there is a greater risk in people’s life in the society, e.g., Bhopal gas Strategy. So the main aim of our project is to detect the presence of mixed numerous gas densities in an area where there is a possibility of eruption of Gas Tanks in the Industrial or in any real time scenario without human intervention. This can be done by designing a real time monitoring system with numerous gaseous detection, with the help of MQ-135 gas sensor, where there is a possibility of integrity of gases to the environment.
