India is an agriculture-oriented country. According to a survey report, 60 percent of the country's land is used for agriculture. This means that a significant portion of the population in the country is involved in farming. As a result, India generates a substantial 7.6 million metric tons of crop residue, commonly known as paddy straw, annually. Farmers consider burning this residue to be a cost-effective solution compared to incorporating it into the soil. However, this practice leads to severe pollution and poses a significant environmental problem.
A solution to this problem has been proposed by researchers at the Indian Institute of Technology Madras (IIT Madras). The researchers have planned to develop an environmentally-friendly technology to repurpose rice straw as an asset by creating supercapacitors. This would enable the production of raw materials from agricultural waste for various industries.
A Source of Income for Farmers: IIT Madras stated in a press release that the researchers have devised a plan to develop environmentally-friendly technology to recycle rice straw for the creation of raw materials to be used in industries. This technology would provide an additional source of income for farmers. Rice straw can be used to produce energy devices that can be utilized by industries.
The Benefit of Organic Waste: Researchers are developing activated carbon from organic waste, especially kitchen waste. Activated carbon is a key component of supercapacitors. Through this research effort, a new 'farm-energy synergy' is being promoted. The use of activated carbon obtained from paddy straw can contribute to a reliable and sustainable source of energy storage. By presenting supercapacitors as a modular attachment, the technology will be beneficial not only to the farming sector but also to the industrial sector. This endeavor will help address the issue of burning crop residues and agricultural waste in Northern India.
Benefits of the Plan: Dr. Joe Thomas, the lead researcher on the project, stated that this initiative would help convert crop residue, particularly rice straw, into economically beneficial carbon material. Moreover, the activated carbon obtained from rice straw can be used in various sectors, including energy, pharmaceuticals, and biocarbons. IIT Madras' researchers have developed an environment-friendly technology that recycles rice straw into activated carbon, which will cater to the needs of electronics, energy, and agriculture sectors and contribute to energy self-sufficiency.
Usage in Various Applications: Activated carbon finds utility not only in the energy sector but also in water treatment, pharmaceuticals, and biochar production. The researchers at IIT Madras who are creating supercapacitors using activated carbon have also noted the potential benefits for the energy and transportation sectors. For example, electric vehicles could benefit from the supercapacitors produced in the campus lab. In summary, IIT Madras researchers are working on a pioneering project that promises to turn crop residues, specifically rice straw, into a valuable resource in the form of activated carbon for various industries. This environmentally-friendly approach aims to address the issue of crop residue burning while providing economic opportunities for farmers and sustainable energy solutions for various sectors.
