Cow Dung: Cow rearing has been practiced in India since ages. Hindu deities are believed to reside in this animal. Cow’s milk has many medicinal properties, which give a boon to a human being to have a healthy and disease-free body. The practice of cow rearing is increasing in the village. The government is also promoting indigenous cow rearing. Adding to this, the model of zero budget natural farming has been invented, so that the cost of farming can be reduced. Cow dung and cow urine are very helpful in this work. Organic fertilizers and fertilizers are made from these for natural farming, which help in improving the fertile power of the soil.
Today, paint, lamps, fertilizers, extracts, toothpaste, soap, decoration items, garlands, bangles and don’t know how many products are being prepared from cow dung. The gas of the stove burning in the kitchen is now also available from the cow dung based biogas plant.
A research conducted some time back has also revealed that cow dung plays an important role in reducing the impurities of water. It can make it reusable by taking out chemicals and heavy metals from the water.
heavy metals will come out of the water
Scientist of IIT-ISM has invented energy storage technology from cow dung, which will also purify water. Actually, with this technique, chemical and heavy metals present in water can be taken out.
In their research, scientists have found that cow dung is very efficient in removing heavy metals and chemicals from water, which can be used in natural energy storage. For this research, cow dung samples were collected from many places and after drying, work was done to purify water from them.
Poisonous water will be used again
Brijesh Kumar Mishra, associate professor of IIT’s Environmental Engineering Department and the scientist who led this research, which makes energy storage and water purification possible from cow dung, told that the water used in industrial works contains many toxic substances and heavy metals.
In these, there is a considerable amount of Cadmium Cd, Cr (Chromium), Pb (Lead), Ni (Nickel), Cu (Copper), Zn (Zinc) etc. On the other hand, due to the heavy metals released from the industries, the amount of lead in the water reaches up to 500 mg per litre.
In addition, 38.4 mg/l zinc from dye manufacturing washing, 45.58 mg/l copper waste from textile mill manufacturing and 35.4 mg/l chromium from paint and paper mill manufacturing industries are released directly into the water. are given.
Scientists have found in their research that cow dung contains many minerals like phosphorus, nitrogen and carbon, which come out of lignin, cellulose and hemicellulose and clean the toxic water. Once water is purified from cow dung, then this water can be used at home as well.
being used in these countries as well
It is obvious that a large amount of contaminated water comes out from industry, which later goes inside the ground and destroys the organisms, but if cow dung is used properly, energy can be saved in industrial work, rather Water can also be recycled and used. Apart from India, Bangladesh and Malaysia are also realizing the importance of cow dung. Like India, these countries have also adopted cow dung and its products.
energy from cow dung
Animal husbandry is done on a large scale in India. It provides economic strength to the rural economy. 9 to 15 kg of cow dung is being received from every big cattle in the village, which is being used only in agriculture, but if proper use of this cow dung is ensured, many villages can produce their own cooking gas.
According to a research done on cow dung, it can also be used in energy storage. For this, in the second phase of water purification research, scientists developed an electrode used as an energy storage device by using an adsorbent obtained from cow dung.
Scientists said that this energy storage device can be made from waste materials, which will be cheap, solar panels can also be connected to it, which will increase the lighting in the village and also benefit the environment.
