Dear Friends and Students
Approx. 680 million tons of rice is grown and approx. 120 million tons of rice husk produced every year across the world. Roughly it contains 97% silica. It produces ash at 700°C and its melting point is at ~1,440°C, proves a good insulation material. Now you can imagine its potential. (frontiersin.org).
Rice husk can provide power to communities. 940 million (13% of the world) do not have access to electricity 3 billion (40% of the world) do not have access to clean fuels for cooking (ourworldindata.org). Husk Power Systems is born (in Bihar) seeing these heart-wrenching statistics. Created a system to turn rice husk into electricity, that is reliable, eco-friendly, and affordable for families that can spend only $2 a month for power. It is started by Gyanesh Pandey, Manoj Sinha, Ratnesh Yadav, and Charles W. Ransler, who met attending different schools in India and the United States. They made multiple experiments and finally started Husk Power Systems (huskpowersystems.com)
Now, SEAT, a Spanish Automobile Manufacturer, is testing the use of rice husk as a substitute for plastic in its new Leon car, especially in the hatchback. It is lighter than plastic! It is a non-petroleum based product. It is going through load tests of up to 100kg. If this works, you would see multiple other by-products of Rice Husk. India produces approx. 24 million tons of rice every year. Assuming 20% of this becomes husk, approx. 5 million tons of husk is produced in India. Bihar alone produces 1.8 billion kilograms of rice husk per year. If it is not used properly, most of it ends up rotting in landfills and emitting methane, a greenhouse gas.!
For Students: Recently one student asked in our discussion: What is the paddy harvesting process? Just for information- Rice Plant->Harvesting (->Rice Straw)->Paddy Drying->Paddy Storage->Milling (Husking (husk)->Polishing(bran))->Milled Rice (knowledgebank.irri.org).
Proposal to Rural Professional Students: You are all living closer to Nature! Can you think of another innovative idea using Rice Husk? Think Big. Waste to Wealth is the Only Mantra.
Your well-wisher
