Stubble Problem Solution : Local or Foreign ?

 


 

Context :

Magnitude of stubble problem grows larger: Govt review  /  ET  /  01 Oct 2022

 

Problem :

 

"The state government had not planned adequately for management of almost 5.75 mt of stubble which is a huge gap and is likely to have an adverse impact on the air quality in Delhi and NCR region," the minister said at the review

The picture is, however, equally worrying in Haryana as well, data accessed by ET shows.

Total paddy stubble generation from Punjab, Haryana and Uttar Pradesh (UP) is expected to touch 27.66 mt in 2022-23 against 26.29 mt in 2021-22, as per data shared by state governments in recent reviews held by the environment ministry, ET has gathered.

This is 1.37 mt higher than the stubble generated in 2021.

It has also been estimated that stubble management plans will probably address up to 20.55 mt of stubble generated in the key states of Punjab and Haryana through both in-situ and ex-situ methods.

 

About 17.70 mt of stubble was managed in the two states last year.

 


And here is a FOREIGN SOLUTION :

 

MIT: Processing waste biomass to reduce airborne emissions   //    30 Sept  2022

 

Massachusetts Instite of Technoloy spinoff  Takachar  has developed a means of converting agricultural waste into clean-burning fuel - winning the Earthshot Prize, the institution announced.


To prepare fields for planting, farmers often burn corn stalks, rice husks, hay, straw and other waste left behind from the previous harvest. In many places, the practice creates huge seasonal clouds of smog, contributing to air pollution that  the World Health Organisation said results in the death of seven million people globally each year.


Annually, $120 billion worth of crop and forest residues are burned in the open worldwide — a major waste of resources in an energy-starved world, said Kevin Kung SM ’13, PhD ’17. Kung is working to transform this waste biomass into marketable products — and capitalise on a billion-dollar global market — through his MIT spinoff company, Takachar.


Founded in 2015, Takachar develops ,

  #  small-scale, low-cost, portable equipment

  #  to convert waste biomass into solid fuel

  #  using a variety of thermochemical treatments,

  #  including one known as oxygen-lean torrefaction.

 

The technology emerged from Kung’s PhD project in the lab of Ahmed Ghoniem, the Ronald C. Crane (1972) Professor of Mechanical Engineering at MIT.


Biomass fuels, including wood, peat and animal dung, are a major source of carbon emissions — but billions of people rely on such fuels for cooking, heating and other household needs.

 

“Currently, burning biomass generates 10% of the primary energy used worldwide, and the process is used largely in rural, energy-poor communities. We’re not going to change that overnight. There are places with no other sources of energy,” Ghoniem said.


What Takachar’s technology provides is a way to use biomass more cleanly and efficiently by,

#  concentrating the fuel and

#  eliminating contaminants such as moisture and dirt, thus

#  creating a “clean-burning” fuel — one that generates less smoke.

 

“In rural communities where biomass is used extensively as a primary energy source, torrefaction will address air pollution head-on,” Ghoniem said.


Thermochemical treatment densifies biomass at elevated temperatures, converting plant materials that are typically loose, wet and bulky into compact charcoal.

 

Centralised processing plants exist, but collection and transportation present major barriers to utilisation, Kung said.

 

Takachar’s solution moves processing into the field - to date, Takachar has worked with about 5,500 farmers to process 9,000 metric tons of crops.


Takachar estimated its technology has the potential to reduce carbon dioxide equivalent emissions by gigatons per year at scale. (“Carbon dioxide equivalent” is a measure used to gauge global warming potential.)

 

In recognition, in 2021 Takachar won the first-ever Earthshot Prize in the clean air category, a £1 million prize funded by Prince William and Princess Kate’s Royal Foundation.

And here is a LOCAL SOLUTION  ( from my email to Shri Sisodiaji ) :

 

Dear Sisodiaji : Here is Stubble Pollution Solution  ………. [ 10 Mar 2022 ]


Extract :

Last evening, while interviewing you on NDTV, Pronoy Roy asked you :

“ So far you have been complaining about air pollution that people of Delhi suffer due to farmers in Punjab burning stubble ( crop residue ). Now that you will govern Punjab, how do you plan to stop stubble burning ? “

Your politically correct answer was :

“  We will think about it. We will find a satisfactory solution “

 

Dear Sisodiaji :

 

Following is a “ satisfactory solution “ costing less than Rs 600 crores ( a tiny

fraction of your poll promises )


And you can easily implement it in 3 months !


More than 4 years ago, I sent following e-mail to all Cabinet Ministers / State

Chief Ministers :


Ø  Smog in Brain ?..................... [ 10 Nov 2017 ]

 

Where I suggested :


              #   About 3 million acres are cultivated for paddy in Punjab and 20

                   million tonnes of stubble are generated every year

                   

                    #   Harvesters skim from the top and leave 80 % of the paddy plant –

                         6” to  8” long – on the field


                    #    Since farmers need to sow wheat within a fortnight of harvesting

                          paddy, they burn the straw , or  paraali , to save time, labour and

                          money

                          

                  #   As per Manjeet Singh Makkar ( Head , Farm Machinery and Power

                       Engineering Department , Punjab Agricultural University ) , following

                       are three solutions :

                       

                  #  Straw Chopper – cum- Spreader

                 This machine chops the stubble and mixes it in the soil either with the

                 help of water or a rotavator


              #   Straw Management System and a “ Happy Seeder “

                It cuts the straw into small pieces and scatters it evenly. Next, a Happy

                Seeder mounted on a tractor can be used to sow Wheat and put the cut

                straw over the area as mulch, which improves soil fertility

              

                The two machines cost Rs 1.25 lakhs

        

        #   A Baler , which bales the straw .

                These can be used in power plants or card-board factories

 

       “ Given a choice between a box of match-sticks and machinery worth Rs 2

         lakhs , what will you choose ? " , asked Billa Singh , a farmer in Phagwara

             

         Now consider this :


         Between harvesting paddy and sowing wheat, there is a 15 day window


·              One pair of machines ( described above ) can work 6 / 7 acres/day


    ·         That is 100 acres in 15 days ( with one pair )


    ·         Paddy Stalk needs to be removed from 30 lakh acres, in 15 days


    ·         That means , Punjab needs 30,000 pairs of machines ( for 15 days )

    ·         One pair costs Rs 2 lakhs

 

·             So , 30,000 pairs will cost Rs 60,000 lakhs ( Rs 600 crores )

 

·             In Maharashtra , nearly 80 lakh farmers will get farm-loan waiver

              amounting to Rs 34,000 crores

 

·             In UP , 12 lakh farmers got farm-loan waiver of Rs 36,000 crore

 

·            Who can believe that Shri Amrinder Singhji ( CM – Punjab ) cannot find Rs

             600 crore to create FARM HELP SPV , which will own those 30,000

             machines and let farmers rent out @ Rs 10 / day ?

             

              

            And , through this method ( # 1 above ) , can we assure the farmers that

            their,

·           #   soil will become more FERTILE

        #   YIELD will go up by 100 %

        #  Income will rise dramatically ,

 

     as the farmers of Maharashtra are discovering , using SRT farming    

    method developed  by Chandrashekar      Bhadsavle 

     

I urge Shri Amrinder Singhji to read the following :


“ A Maharashtra Farmer’s AgriTech Holds Promise for Delhi’s Pollution Woes 

https://economictimes.indiatimes.com/news/politics-and-nation/this-farmers-agri-technology-can-help-solve-indias-pollution-woes/articleshow/61600114.cms

 

And can someone figure out how to combine this [ SRT ] with the following

technology from China to provide a powerful incentive to the Punjab farmers to

stop burning paddy stalk ?

Shri Sisodiaji  [ msisodia.delhi@gov.in ] 

 

Shri Bhagwant Mannji  [ bhagwant.mann@sansad.nic.in  / bhagwantmann@gmail.com ]

 

Shri Raghav Chadhaji  [ raghavchadha111188@gamil.com ]

 

I hope that this solution is adopted in the very first meeting of the new AAP government in Punjab

Barely one-third of the crop residue administration machines deployed by Punjab authorities to discourage farmers from burning stubble have been used.

As farmers harvest paddy and prepared their fields for rabi crops, Punjab authorities has ready an intensive month-long motion plan to stop stubble burning, which contributes to pollution in northern India. At the core of the motion plan is behavioural change of Punjab farmers who’ve been shunning mechanisation of harvesting and crop residue administration. Speaking to ET, Punjab Pollution Control Board member secretary Karunesh Garg stated, 

“About 50% of the paddy straw generated is treated in-situ, which means the farmers burn them. 

Punjab agriculture department and the pollution control board are running an intensive campaign to discourage farmers from burning the stubble. We are increasing awareness that machines are available for them to use.

” There are 90,000 crop residue administration machines out there for the farmers.

 “The usage is very low. Just about 30-35% machines were used till the last harvest season in March-April,” stated Garg including, “If we are able to improve this utilization to 50%, it should make a giant distinction in stubble burning incidents.”

The Punjab authorities has gone down to the micro-level and has launched iKhet app which maps these machines to farmers and reveals availability

The agriculture division has recognized hotspots on the idea of fireside incidence and has elevated the allocation of machines in these areas. 

However, the quantum of the stubble drawback has solely elevated. 

As per PPCB statistics, paddy straw generated final 12 months was about 18 million tonnes however with space below rice cultivation growing additional, about 19.99 million tonnes of paddy straw is probably going to be generated this season.

 “About 50% of the paddy straw is treated in-situ, which is about 9 million tonnes is either burnt or mechanically treated using machines in the field. 

About 2.5 m tonnes is used as fodder. 

The remaining is an opportunity for ex-sity usage – which includes waste to energy or in industries,” stated Garg. 

However, final 12 months, Punjab may use barely 1.2 MT ex-situ

The goal this 12 months is sort of doubled to 2.1 MT. 

Last 12 months, industrial boilers used 0.3 MT and this 12 months, about 0.7 MT of paddy straw is probably going to be despatched to boilers. 

There had been tie-ups with 5 industries final 12 months, which has one up to 12 this 12 months,” stated Garg.
