Nagpur: A city-based organic products company, Biocare India Pvt Ltd, has developed a fast-acting waste decomposer for agricultural waste. This bio decomposer can convert the agriculture waste into bio-manure in 30-40 days instead of the conventional time of 90 days.The waste decomposer is particularly useful for sturdy waste like the rice straw, the sugar cane stubble etc which are otherwise difficult to decompose. Generally, the farmers burn this waste. The burning of the rice waste in the fields in Punjab had caused pollution and smog in Delhi that forced the educational institutions to shut for many days last year.The new waste decomposer by Biocare can apparently prevent this burning as the entire waste can be decomposed in the process without causing any pollution. Biocare chairman-cum-managing director Suhas Budhe told TOI that though the company is in the process of testing the results at various places in the country, initial results in the company’s fields were very promising.The company has basically used a consortium of three different types of bacteria. They can enhance the pace of the composting. These bacteria were first mutated using irradiation by the Bhabha Atomic Research Centre (BARC) Mumbai, which is a partner in the project. “We cannot share the names of the bacteria yet but BARC has patented them. Normal composting takes about 90 days but our decomposer converts the waste into manure in just 30-40 days,” he said.Composting can be done in two ways. In the first process, the waste left after cutting the paddy or the sugar cane the field is left as it is and the waste generated after cutting the crop is spread throughout the field along with the mixture of the bacteria. In the second process, all the waste is dug out and stored at one place and the composting procedure is implemented.Budhe said that only one kg of the bacteria is needed to decompose 1 tonne of the waste. The total process costs Rs1000 per tonne along with labour etc. The rapid composting minimizes the composting time as well as improves the quality of the bio-manure.The process is basically simple and reliable. The compost is available as ready to use. It has longer shelf life. It converts the organic waste into compost. It is low cost product. “Best results are obtained when proper aeration is facilitated by turning the pile periodically. This ensures uniform composting,” said Budhe.
