With the development of agriculture in India, the production of agricultural wastes increased rapidly. Basically these wastes are bio products and are very important for survival of animals and human beings. The occurrence of agricultural wastes is unique in the different areas. The agricultural straw and livestock excrement are considered to be potential resources. These substances are widely available on earth and can be a good source of energy or be converted into useful products. The wastes generated from crop have a good potential to convert to energy through related energy sector. The waste produce from animal or from crop residue is called biomass which has an interdependent relationship with ecosystem from production to disposal and has physicochemical properties. The recycling and utilization of agricultural wastes are considered to be the important step in environmental protection, energy structure and agricultural development. The present review deals with the research work carried out in the conversion of biomass and agricultural waste and to illuminate the potential environmental risk, recycling and utilization pathway, influencing factors and policy suggestions in the recycling and utilization progress of agricultural wastes. An attempt is carried out to increase the economic value of agricultural waste into useful product. The survey provided the development mode of industrialization and scale of agricultural waste recycling. The recycling and utilization pathway of agricultural wastes were also analysed. The crucial suggestions may be proposed, such as cultivating new industry, building economy incentive standard, improving laws and regulations, and creating rural market strengthening medium and long-term plans of agricultural waste recycling. The resource consumption, ecological crisis and other issues caused by agricultural wastes were evaluated.

The emerging concept of university social responsibility (USR) consists in the fulfillment of the mission of the university in terms of ethical standards, community support, respect for human beings, and respect for the environment. Thus, universities must not only provide professional training but also instill ethical principles in students to allow them to behave as good citizens and help solve community problems. On the other hand, competition for students requires efficient management of university reputation and communication with their stakeholders, to demonstrate the accomplishment of the university’s mission and attract potential students. The objective of this paper is thus to explain the causal relationship between communication about university social responsibility (USR) activities through institutional websites and university selection, as well as the role of reputation. Research work was carried out based on an explanatory cross-sectional design, with a sample of 356 subjects from a population of 11th-grade students from public and private schools in the City of Barranquilla (Colombia). The results revealed that USR communication through institutional websites has a significant influence on university selection, not only directly but also indirectly, through reputation as a mediating variable. These findings contribute at a theoretical level by providing empirical evidence to understand and explain the analyzed topic. Furthermore, the results provide useful information to evaluate USR disclosure and implement strategies to make progress on USR issues. Resumen El naciente concepto de responsabilidad social universitaria (RSU) consiste en el cumplimiento de la misión de la universidad dentro de unos estándares éticos, de apoyo a la comunidad, respeto al ser humano y al medio ambiente. Así, pues, la universidad no sólo debe impartir formación profesional, sino inculcar a sus estudiantes principios éticos que les permitan comportarse como buenos ciudadanos y contribuir a la solución de los problemas de la comunidad. Por otra parte, la competencia entre universidades exige una gestión eficiente de su reputación y de la comunicación con sus distintos stakeholders, para demostrar a la sociedad el cumplimiento de su misión social, y para atraer estudiantes potenciales hacia la institución. Por lo tanto, este artículo tiene como objetivo explicar la relación de causalidad entre la comunicación de las prácticas de RSU en los sitios web institucionales y la selección de universidad, y el papel mediador de la reputación en esta relación. Para lograrlo, se llevó a cabo una investigación cuantitativa de nivel explicativo experimental y diseño transversal, con una muestra conformada por 356 sujetos, de una población de estudiantes de grado 11º de colegios públicos y privados de la ciudad de Barranquilla (Colombia). Los resultados revelan que la comunicación de las prácticas de RSU en los sitios web institucionales ejerce una influencia significativa directa en la intención de selección de universidad, e indirecta, a través de la reputación como variable mediadora. La evidencia empírica aportada representa un avance teórico en la comprensión y explicación del fenómeno estudiado, e igualmente servirá para que las universidades evalúen si están comunicando adecuadamente su responsabilidad social y adopten estrategias para avanzar en este aspecto.

Edward Schillebeeckx’s theology of creation can serve as a foundation for authentic Christian self-understanding in relation to the ecological crisis. Schillebeeckx provides a Thomistic view of humanity and creation as both autonomous and “given” from God. Schillebeeckx’s anthropocentric “creation faith” and nuanced view of secularization provide a way of preserving the uniqueness of humanity without devaluing nature. Structural parallels with Pope Francis’s Laudato Si’ are developed in order to provide a fundamental-theological foundation for determining the proper role of human beings in relation to creation.

Abstract Bamboo trees are one of the fastest growing trees in tropical rainforests around the world, they have various uses ranging from construction to fly ash generation used in oil and gas cementing, to development of activated carbon which is one of the latest uses of bamboo trees. This paper focuses on development of activated carbon from bamboo trees for carbon capture and sequestration. The need for improved air quality becomes imperative as the SDG Goal 12 and SDG Goal13 implies. One of the major greenhouse gases is CO2 which accounts for over 80% of greenhouse gases in the environment. Eliminating the greenhouse gases without adding another pollutant to the environment is highly sought after in the 21st century. Bamboo trees are mostly seen as agricultural waste with the advent of scaffolding and other support systems being in the construction industry. Instead of burning bamboo trees or using them for cooking in the local communities which in turn generates CO2 and fly ash, an alternative was considered in this research work, which is the usage of bamboo trees to generate activated, moderately porous and high surface area carbon for extracting CO2 from various CO2 discharge sources atmosphere and for water purification. This paper focuses on the quality testing of activated carbon that can effectively absorb CO2. The porosity, pore volume, bulk volume, and BET surface area were measured. The porosity of the activated carbon is 27%, BET surface area as 1260m²/g. Fixed carbon was 11.7%, Volatility 73%, ash content 1.7%.

Nutmeg is a source of income for some people in South Aceh, and some types of nutmeg, like mace nutmeg, are of better quality. Mace nutmeg is also an agricultural community with great economic value and benefits for humans, as it can be processed into spices and herbs. A range of products includes nutmeg oil and medicines. The harvesting and drying of mace nutmeg, which is still considered a problem by nutmeg growers, cannot be isolated from the processing of the basic ingredients. The natural process of drying mace nutmeg involves the use of sunshine, which necessitates a considerable drying time. Therefore nutmeg farmers frequently complain of erratic weather, especially during the wet season. The constant rain can cause the mace to rot, causing the nutmeg farming community's revenue to become unstable. Methods and steps of research work starting from the study of literature, determination of design specifications, hardware design, software design, toolmaking, tool testing.Good results were reached with the dryness of the mace nutmeg, which can be adjusted, and without putting into account the weather in the drying process, which is usually done with the heat of the sun, per the results of the testing of the designed tools.The average dryness of mace nutmeg is at a temperature of 45 percent with a time of 4 hours and a capacity of 100 grams; according to the test results of the automatic mace drying machine, it produces 50 grams of dry mace.

Fishes are found adequately in the different water sources of Jaunpur India. Five rivers (Gomti, Sai,Varuna,Pili and Basuhi) ,Gujar tal and different pond are available here as a aquatic habitat. In research work author consider only two sites of river Gomti and two different ponds in district Jaunpur, U.P. They are external as well as internal .In this studyauthor focused on digenetic trematodes parasites. Digenean trematodes are completing their life cycle in two hosts so both are susceptible to the infection. There are considerable change occur in the environment wih the passage of time. We also know that environmental factors affect the life forms of any place. So it is important to study the different ecological terms in relation to the host and their infectious agents. From ancient time humans beings use large amount of fish food for survival because they are easily available from different water sources. When human beings eat unadequate cooked fish then suffered with food borne tremadiases.So it is important to know the infection level in the fishes.

Electronic e-waste (e-waste) is a growing problem worldwide. In 2019, total global production reached 53.6 million tons, and is estimated to increase to 74.7 million tons by 2030. This rapid increase is largely fuelled by higher consumption rates of electrical and electronic goods, shorter life cycles and fewer repair options. E-waste is classed as a hazardous substance, and if not collected and recycled properly, can have adverse environmental impacts. The recoverable material in e-waste represents significant economic value, with the total value of e-waste generated in 2019 estimated to be US $57 billion. Despite the inherent value of this waste, only 17.4% of e-waste was recycled globally in 2019, which highlights the need to establish proper recycling processes at a regional level. This review provides an overview of global e-waste production and current technologies for recycling e-waste and recovery of valuable material such as glass, plastic and metals. The paper also discusses the barriers and enablers influencing e-waste recycling with a specific focus on Oceania.
