Modi, Swedish king to launch pilot project in Mohali for making green coal from paddy stubbleUpdated: Nov 29, 2019 12:42 IST
What if all the paddy stubble that is causing Delhi-NCR’s air to turn so toxic due to burning is turned to something useful instead? Sweden is showing the way to turn the troublesome stubble into green coal or energy pellets that can be used as fuel instead.
On Monday, Prime Minister Narendra Modi and visiting Swedish King Carl XVI Gustaf would through pressing of a button to officially launch a pilot project in Mohali, Punjab, to produce green coal with paddy straw, with the collaboration of Swedish firm Bioendev.
In January this year, National Agri-Food Biotechnology Institute (NABI), in Mohali, signed a memorandum of understanding (MoU) with Bioendev AB, Sweden, to set up the pilot project.
The government of India and Bioendev AB are in a 50-50 collaboration on the project.
The Swedish firm, which specialises in turning forest waste into energy pellets, has fine-tuned its process to make it suitable for paddy and wheat straw, Swedish ambassador Klas Molin said.
A huge plant has been set up in Mohali to convert paddy straw into the energy pellets, said the envoy.
NO CARBON FOOTPRINT
The plant uses the process of torrefaction, a thermal process to convert biomass into a coal-like material. The green coal leaves no carbon footprint.
According to Bioendev’s website, energy from 35 million tonnes of paddy is wasted every year in India. It can be converted to bio coal and replace 21 million tonnes of fossil coal a year.
This would work out to 48 million tonnes of carbon dioxide equivalent reduction, or equivalent to green house gas emissions from 10.2 million Indian cars.
According to the website, the Bioendev process of turning biomass, in this case stubble, into green coal offers an effective alternative to fossil fuels such as coal, and helps to significantly reduce the carbon footprint.
STUBBLE TO HOME DECOR
Not just green pellets. Sweden has other things on offer to turn paddy stubble into useful alternatives such as table mats, decorative pieces and lamp shades.
Swedish major Ikea, the world’s largest furniture retailer, has been collecting paddy stubble from farmers in Punjab and working on ways to turn it into attractive home decor.
The stubble is mixed with textile material through a process. The end products, in blue and white, would be exhibited on Tuesday at a function at the Habitat Centre in Delhi to be graced by the Swedish royal couple King Carl XVI Gustaf and Queen Silvia.
Ikea has been working with farmers in Punjab for the past two years on this project, Molin said.
The spike in air pollution is mainly due to the burning of paddy stubble and straw in the fields of Punjab and Haryana after the kharif crop is harvested. To plant the rabi crop in October, farmers clear their fields in a hurry, and stubble and straw burning is the fastest and cheapest way to do it. The smoke from the burning stubble blows into neighbouring Delhi, and combined with the pollution from vehicles, causes heavy smog.
The Swedish royals are visiting India from December 2-6 at the invitation of President Ram Nath Kovind. They will travel to Delhi and Mumbai besides the state of Uttarakhand.
