Recycling of human excreta /waste

Recycling of human excreta /waste

Approximately each human needs 1250 grams (1.25 kg) to consume as food from more raw agricultural produces each day. We can assume the quantity of organic waste from human excreta (Waste matter, such as sweat, urine, or feces, discharged from the body) every day in India connected with population. From this organic waste we can produce more to feed the entire population by protecting soil degradation. The sewage waste are dumping at those places where roots of plants and trees can't reach. Thus the organic recycling is a difficult one. When the population density increases E.coli bacteria spread in rivers, wells etc which affects human health. It is our duty to save the soil, air and water from polution of our generation as well the coming generations. 

This is an eco-friendly tiolet designed by Biotech at Trivandrum which is a private firm. The installation of these type of toilet can be build for single or collective basis. We can use other organic wastes with it to produce more bio gas and slery. We can apply slery directly to plants and trees with doubled nutrients than ordinary organic manure. In this way by treating drainage waste without soap water can provide bio gas by fermentation process with the help of methrogenic bacteria. The colifarm bacteria will be at deadly stage on slery. "This is a great revolution if it is brought to practice properly. The question of recycling of human excreta /waste was discussed by Karl Marx and Karl von Leibig way back in 1843. There should be different models. Wide scale demonstrations etc. Study results regarding the items of concern should be well discussed like Microbial load, parasitic load etc." said by Dr. K.M.Sreekumar,Associate Professor (Agrl. Entomology),College of Agriculture, Padannakkad, Kasaragod 671 328, Kerala.

This is a multipurpose bio gas plant of keralafarmer constructed by Biotech-India with water jacket system including inner and outer cylinders to take maximum benefit of fermentation process and given Rs. 3500 as subsidy from Govt of India. Between the two cyliders around the bio gas container fresh water is available which can use to feed small fishes to reduce larve and mosquitos. The manhole at right hand side for sewage waste without soap water from bathroom. Soap water will not support fermentation process. At left hand side in higher level is for the input of cowdung diluted with 1/3 water and other organic wastes from the house. At the rear end at left hand side the manhole is the exaust of slery. 4" PVC pipes are used on both sides of input and output which can be cleaned with a long stick on any obstacles.

By using the sewage waste with other organic matter can produce more grains than we uses. It keeps the soil healthy for agriculture, clean water to drink and the clean air for us to breath without allergies to human.
