Cow dung: a dirty Big work in India, Part 1

At first glance, a pile of fresh cow dung deposited on the road may not seem like much, and just under a pile of cow dung. But after traveling in rural India, the tourists are starting to see this resource, as the Indians: the goods in order to survive so intertwined that it is almost impossible to imagine life without it.

There are more than 283 million cows roaming the terrain in India. This is equivalent to more than 700 million tons of fertilizers are manufactured on a daily basis, must be collected, distributed, disposed of or otherwise used in any other way. Surprisingly little wasted, because the genius of the Indian rural population. Part 1 uses cow dung in India focuses on collecting, drying and burning of organic wastes.

Enough fuel to support energy in the country, 1.1 billion people may seem an insurmountable task. 75% of India’s population lives in rural areas, and continuous access to fuel still a luxury for most people, the daily food and heating will depend on cow dung. The lack of firewood or brush are many ways of rural India will be forced to turn cow dung for their energy needs. The heat from the flames of dried cow manure, leaves much to be desired and, therefore, other additives are combined to create a better combustion.

Manure is collected by men and women, but is generally left to women to complete the process of mixing and drying of manure. Farmers and villagers who have their own cows have a lot of manure a source close to the people or those who can not afford a cow wandering roads of their own local or popular routes where the cows run frequently. Young children are often recruited and are paid very little to accomplish this task in the cities that still rely on the old tradition of burning cow dung.

Once collected, the manure is mixed with straw or coal, formed in melon-sized ball and press firmly against the wall with good sun exposure. In good weather, flat round discs (about 8 “in diameter) is dried and ready to record within 3 to 4 days. Storage of dried cow manure disks varies by region of India. In the villages where tradition still batteries run deep, wonderful cow dung were removed. The top of the pile, the most influence on people. In other villages, it is common to see dried manure piles in a bridge structure of fortune, and then covered with a layer of fresh cow dung which designs are drawn still wet. The internal storage offers protection from the monsoon and winter season, it is difficult to produce more fuel hamburgers.

It is unfortunate drawbacks of the use of dried cow dung patties for fuel. Long-term exposure to airborne particles has been associated with higher rates of cataracts and other eye problems, acute respiratory infections (including tuberculosis), chronic obstructive pulmonary disease and cancer. Studies have found an increased incidence of these problems among people who use manure as fuel inside for cooking or heating. Other studies of households in cow dung-cake-fired kilns used consistently have found significant concentrations of arsenic in indoor air samples. Inhalation of arsenic can cause respiratory problems such as persistent cough, chronic bronchitis and changes in X-rays.

Cooking with cow manure is not very different from that of wood or other gases. The flame lit under the pots and pans, or fanned by cooling to achieve the right temperature, and quickly came to a halt when the cooking is completed. Flue fire is said to improve the taste. Many of the Indians swear the food tastes when cooked in coals cow manure is much more than food cooked in an ordinary petrol or kerosene.
