In almost all developing countries, the lack of adequate supplies of cheap, convenient and reliable fuel is a major problem. Rural communities depend largely on kerosene, wood and dung for their cooking and lighting needs. But kerosene is now priced out of reach of many people and wood, except in heavily forested areas, is in short supply. The search for firewood occupies a large part of the working day and has resulted in widespread deforestation.
Dung is in constant supply wherever there are farm animals and, when dried, it is convenient to store and use. But burning dung destroys its value as fertilizer, thus depriving the soil of a much needed source of humus and nitrogen.
Rural areas of developing countries are also plagues by a lack of adequate sanitation. Improper waste disposal spreads disease, contaminates water sources and provides breeding ground for disease-carrying insects.
The problem of improving environmental hygiene, conserving resources and finding alternative sources of fuel may be unrelated. Their solutions, however, are not, as many countries experimenting with biogas technology are discovering. Biogas, a mixture of methane and carbon dioxide, is produced by the fermentation of organic matter. The process of anaerobic fermentation is a natural one, occurring whenever living matter decomposes. By containing the matter – and the process – in a digester or biogas plant, the combustible gas can be trapped and used as fuel for household lighting and cooking. The digested slurry that remains can be used on the land as a soil conditioner and fertilizer.
Biogas plants have attracted much interest in recent years and they are in use in several Asian countries: 38,000 are reported in rural area of India, 27,000 in Korea and more than 80,000 in China. In most countries, the value of the gas has been the prime factor leading to their adoption: 70 percent of India’s plants, for instance, were built during the energy and fertilizer crisis of 1975-76 – although their use in that country dates back to 1951. similarly in Thailand and Korea, biogas is being investigated as an alternative to costly charcoal and to save compost materials form being burned.
In Japan and China, reducing pollution from animal wastes has been an important factor. Privies, hen houses and pigpens are built in proximity to the fermentation chamber in China. Examinations of the digested slurry have shown that the total number of parasite eggs was reduced by 93.6 per cent, hookworms by 99 per cent and no schistosome flukes were found.
The greatest benefits from biogas systems, however, are probably to be derived from the manorial value of the slurry, although it is not widely used outside of India and China. Vegetable farmers near Calcutta found that the digested slurry produced bigger and better tasting peas than did other fertilizers and the weight of root vegetables increased by nearly 300 per cent.

Etiquette is the name we give to the rules for being polite in a social group. Business etiquette is important for people who often have to make new contacts and build relationships in their work. Politeness can also help to improve the working environment for people in the same office. Some cultures and situations are formal, which means that we have to follow rules; other cultures and situations are more informal.
Text 2 Office workers “admit being rude”
Most office workers say they are rude or bad-mannered at work. Two out of three workers regularly arrive late for meetings, most ignore emails and three out of four use bad language. In a survey of 1,000 workers, two-thirds say that pressure of work is the reason for bad manners.
Other common examples of bad office etiquette include ignoring colleagues and answering mobile phone calls during meetings. Using mobile phones in meetings is impolite and distracts others, research by the University of Surrey shows. If you respond to call when speaking to somebody, it means that the phone call is more important than the person, the survey said. If you answer a call during a meeting, it could mean that the meeting is not important.
Mr Jacobs, managing director of Office Angels, a recruitment firm say it is easy for people to forget their manners in the working environment, which is often very informal and very busy. Workers can forget proper etiquette such as introducing people at meetings, and this is often bad for working relationships.
Psychologist Dr Colin Gill believes that people are not as polite as they were twenty years ago. He said: ‘Courtesy is no longer something that is so much respected in our society.’ People think it is ‘stuffy to be polite or formal.’
Now some organisations are actually investing money in training their junior managers to be polite. Office Angels is encouraging people to arrive on time for meetings, turn off mobile phones and avoid bad manners at work is such a simple thing to do,’ Mr Jacobs says, ‘ and it can have a dramatic impact on improving your working environment and your relationships with others.’
