“It’s Not Easy Being Green” (May–June 1994). Help the environment and hurt your business, or irreparably harm your business while protecting the earth. Recently, however, a new common wisdom has emerged that promises the ultimate reconciliation of environmental and economic concerns. In this new world, both business and the environment can win. Being green is no longer a cost of doing business; it is a catalyst for innovation, new market opportunity, and wealth creation. The idea that a…

Sponge Iron plants are highly air polluting plants. This type of industry is allowed only in Asian countries especially in India.What are its alternative and how it can be converted into less polluting is challenge of today. We should discuss on this issue.

Due to continuous high population growth and rapid economic development in urban areas, many public, private and informal sector service providers in cities in developing countries are unable to cope with increasing volumes of solid waste, especially in poor and low-income areas.



Regular and safe disposal of solid waste is the basis for hygiene and prevention of diseases and hence the foundation for any development activities oriented at poverty alleviation…

Environmental sanitation is a major public health issue in India. Recent interventional studies on environmental sanitation in India highlighted the importance of prioritizing control strategies. Environmental sanitation envisages promotion of health of the community by providing clean environment and breaking the cycle of disease. It depends on various factors that include hygiene status of the people, types of resources available, innovative and appropriate technologies according to the…

Decentralized treatment systems in India

India is the country with the highest number of people practicing open defecation. Around 600 million people in India defecate in the open which is more than the next 13 countries combined. India counts for 90% of the people in south Asia and 59% of the 1.1 billion people in the world who practice open defecation (Unicef, 2015). As can be seen from the image, almost 3/4th of Indian states have 50% or more…

Appropriate sanitation facilities are still a challenge in many parts of the world, particularly in developing countries. With regard to almost 950 million people defecating in the open, the question arises whether the existing treatment facilities are sufficient to provide for a healthy sanitation in the world. In developing countries (particularly, India) where cost is generally a very important parameter of judgment for choosing the appropriate system. This makes decentralized…

Smog now darkens the sky in cities the world over, and the same is happening in Delhi. The air we all breathe is increasingly contaminated with particulate matter and carbon monoxide. These pollutants are hazardous to human and environmental health. So how can you personally clean up the air? You might be surprised to learn how much your efforts can help reduce this pollution.

Coal will continue to be an expanding, cheap foundation for economic and social development. Backed by its vast and well-distributed resource base, coal has the potential to make a significant contribution to eradicating energy poverty. Coal can be increasingly clean - at a bearable cost in terms of technological sophistication and at little cost in terms of international technology transfer and R&D in CO2 sequestration. For this to happen, a more pro-active involvement of the…

Industrial revolution followed by the advances in information technology during the last century has radically changed people's lifestyle. Although this development has helped the human race, mismanagement has led to new problems of contamination and pollution. The technical prowess acquired during the last century has posed a new challenge in the management of wastes. For example, personal computers (PCs) contain certain components, which are highly toxic, such as chlorinated and brominated…
