A Review Paper on Green Building Research
One of the most common issues on the word right now is green building technology, with the goal of reducing the development industry's various negative effects on the environment, society, and economy. Because pollution and global warming are quickly expanding over the planet, the world urgently requires a sustainable and reasonable development. Because of the increase in Green House Gases (GHGs), dramatic climatical differences occurring everyday have been noted and are being faced by almost everyone all over the world. Within settled countries such as the United States of America, Russia, Australia, and the United Kingdom, there have already been rigorous steps taken to achieve workable development, as well as rules and regulations enacted by their respective governments to assist and accomplish a workable and environmentally approachable development of their countries. However, emerging countries such as India, China, Sri Lanka, Pakistan, and others are dragging in terms of founding supportable growth and environmentally friendly structures. In addition, there is a deficiency of public understanding about this worldwide issue in these emerging countries. According to surveys and study, these countries are also far behind schedule the established nations of the world. This article discusses the need for maintainable growth around the world, particularly in emerging countries such as India and China, which have enormous land-living masses and are fast emerging, with the potential to become new global superpowers in the near future. It also includes sustainable and monetary research with connections to Indian contexts, as well as a recent live instance study of a freshly built and constructed luxurious housing home in a densely populated area of India. The case study is a inhabited house that is planned and built as a sustainable and green structure in an extremely community inside the state of Maharashtra, India, as India is also known as a country of villages with the world's second largest population. According to India's 2012 census, 69.84 percent of the population, or 869.17 million people, live in 6,47,861 distinct villages. By using straightforward, simple, and cost-effective strategies, this study will assist Indian communities and residential buildings in becoming more sustainable and greener.

Sustainable domestic wastewater treatment in urban areas
Sustainable domestic wastewater treatment in urban areasRetired from Saxion University of Applied Sciences
This document summarizes Gerard A.M. de Fraiture's contribution to an international seminar on sustainable domestic wastewater treatment in urban areas. Conventional wastewater treatment systems in western countries are not very sustainable. Research shows that anaerobic treatment, which mimics natural biological processes, is more sustainable as it recovers energy and nutrients in a decentralized manner. Promising technologies like upflow anaerobic sludge blanket reactors and recent algae technologies follow principles of separating solids from liquids and minimizing water use for transport. Simple, robust, affordable technologies at small scale can create jobs and economic opportunities while achieving sustainability goals."Waste Management Vision For Future" - م.15- مبادرة #تواصل_تطوير- أ.د. مصطفى...

The Iron Catastrophe around 4.5 billion years ago was one of the most crucial events in Earth's formation. As the hot young planet cooled, elements like iron began moving toward the center and formed the first core. The temperatures were so high - around 1,538°C - that iron melted. Some elements like silicates and water remained near the surface while others like iron and nickel sank toward the core. Today Earth's core is still molten compared to the outer geological layers.
