Action Plan for Biomass Management | 09 Jul 2018

Introduction

The farm burning, specific to the paddy-wheat cultivation cycle in the rural regions of Northern and North-Westerns states of India, has been identified as a major source of air pollution. It not only affects the air-quality in rural areas but also causes an episodic rise in air-pollution during October and November in Delhi-NCR.

CII-NITI Aayog ‘Cleaner Air Better Life’ initiative aims to bring together all relevant stakeholders for designing a set of solutions to the identified sources of air pollution. For this initiative, the findings of IIT-K study are being considered as basis of designing the action plans.

Anchored by the Ministry of Environment Forests and Climate Change, the task force on Biomass Management has identified certain avenues for the alternate usage of paddy straw/crop residue

The task force has suggested a two-pronged approach to tackle the issue:

From the farmers’ end

  • In-situ utilisation or soil incorporation of crop-residue (that remains standing in the field after combine harvesting) needs to be prioritised and popularised among the farmers. This is important, not only to ensure that crops are not burnt but for long-term conservation of micro nutrients in the soil.
  • In-situ utilisation of straw which remains rooted in the soil, requires a change in farming practices. For this purpose, specialised machinery is required at different stages of farming.
  • Apart from directly ploughing and mixing (mulching) the residues back into the soil, on-farm management techniques (composting, pyrolysis or biochar) are effective in bringing the nutrients back to the soil
  • There is increasing evidence that soil incorporation has long-term benefits for improving the quality of soil, increasing water-use efficiency and reducing the intensity of fertilisers being used.

From the government’s end

Table 1: Actions to combat air pollution by subtle burning

Immediate action

Medium and long-term actions
Financial support to farmers Impact fund for Air-pollution Upscale technologies Reword and Monitor at local level Regulatory support Awareness tools
  • Incentives to farmers through Direct Benefits Transfers.
  • Set-up clean impact fund to support clean technologies and link it with the national clean Energy Fund
  • Service-based shared infrastructure (with 50% capital subsidy on select implements).
  • Process-based incentives.
  • Accelerated depreciation for farm implements.
  • Reword for panchayats INR 1 Lakh per panchayats with zero burning.
  • Monitoring through advanced remote sensing data and mobile base app for general public.
  • Reassessing fuel for criteria for briquettes/
    pellets From paddy-straw.
  • Directive to thermal power plants to produce paddy-straw briquette/
    pellets
  • Removing the size limitation for bio-power captive generation
  • Awareness campaign for farmers.
  • Farmer recognition programme.
  • Manuals and information tool for in-situ mulching and on farm management


Table 2: Solutions and technologies for utilisation of farm waste

S. No Utilisation Methods Applications Barriers Enablers
1 Biochar
  • Soil conditioner
  • Bio remediation
  • For making value added products
  • Lack of financial support
  • Lack of equipments
  • Awareness on benefits
  • Market development for biochar products
  • Research and development
2 Briquetting
  • Fuel in gasification furnace, heaters, hot-water boilers, industrial boilers
  • It is a very good substitute for furnace oil, coal or direct wood.
  • Lack of availability of dry biomass because of dew in winter season.
  • Lack of transportation facilities
  • Proper recognition for industry and those using briquettes.
3 Pelletisation
  • It has good potential for being used as fuel in cooking stoves and heating applications in domestic as well as industry.
  • Availability of raw materials crucial for business model.
  • Often has a large size that leads to a high storage and transportation cost.
  • Subsidy on cook stoves targeting specific users for replacing wood or coal usage.

BioCNG

  • Commercial–hotels, canteens, bakeries, resorts, residential clusters.
  • Industrial-glass and ceramic, cement, metal process, textiles, food processing,
  • Lack of financing.
  • Organized supply chain-Transportation of raw material from farmer to biogas plant needs to be streamlined.
  • Funding support to entrepreneurs willing to establish 2G biogas/ Bio CNG units under NABARD soft loan scheme.
  • Exemption of GST on Biogas/Bio CNG and capital equipment and installation
  • Tax breaks
5 Liquid fuels
  • The petrol and diesel produced through this method will conform to Bharat VI norms and can be used directly in cars, trucks, engines etc
  • Varying feedstock costs (collection and transportation costs might vary).
  • Storage and transportation
  • Effectiveness and efficiency needs to be proven
  • Monetize urban/rural wastes (assigns economic value to wastes)
6 Bio-ethanol
  • It could pave a way in the future for second generation biofuels derived from crop-residues
  • Lack of investments
  • Pre-treatment of paddy straw is being deployed at commercial scale and viability gap funding can be explored for such projects
