Rice cultivation leads to the production of a significant amount of residual biomass in the form of paddy straw (PS) and husk, grossly amounting to ~134 MMT annually. The energy content of PS is 10-14 MJ/kg. The surplus PS production in the country is estimated to be over 40 MMT. There is a need for developing cost-effective technologies to utilise the PS for the production of bioenergy and bioproducts. The article talks about some of the research advances that are being made for enhanced offtake of PS.
Rice is one of the primary agricultural produces in India and a major source of sustenance. India is the secondJargest producer of rice in the world accounting for almost one-fifth of the world's supply, with an annual production of ~122 MMT (Olafisoye et al., 2022). Rice cultivation also leads to the production of a significant amount of residual biomass in the form of paddy straw (PS) and husk, grossly amounting to ~134 MMT annually. (Singh et al., 2016). The energy content of PS is 10-14 MJ/kg. The surplus paddy straw production in the country is estimated to be more than 40 MMT. Paddy cultivation, its residue decomposition naturally, or the stubble burning of paddy straw causes environmental degradation and loss of energy-rich products. The surplus PS can be an excellent feedstock for the production of bioenergy (bioethanol, biogas, biochar, pellets, briquettes, green hydrogen, etc.), and other bioproducts (Dash et al., 2021; Singh et al., 2016). Thus, there is a need for developing cost-effective technologies to utilise the PS for the production of bioenergy and bioproducts. Following are the existing pathways in which research advances are being made for enhanced offtake of paddy straw.

Small farmers are the greatest asset to India's food security: PM Modi
Prime Minister Narendra Modi centre) along with other dignitaries at the inauguration of the 32nd International Conference of Agricultural Economists ICAE) at National Agricultural Science Centre NASC) Complex, in New Delhi on August 3, 2024.
Agri Budgeting Blues
Budgeting blues is a wonderful term to identify what you have and what is necessary to investigate the need. When one deciphers the current Budget specifically for the farm sector blues, there is little Khushi (Happiness) and more Gum (sadness).
Unlocking the Potential of Municipal Solid Waste
The more conventional methods of managing waste, such burning and landfilling, become unsustainable. Landfills, although still in widespread usage, are land-use intensive and provide long-term environmental hazards, such as methane emissions and groundwater contamination. Even while incineration is a good way to reduce trash volume, it is energy-intensive and emits dangerous emissions. Cities are looking for new and creative approaches to manage garbage sustainably as conventional approaches become less practical.
Why Energy Transition Financing is Crucial for India
The whole world is badly hit by the cost of energy, including fuel, due to the ongoing geo-political issues. India’s net oil and gas import bill reportedly stood at 122 billion for 2023-24. The Indian economy is the fastest growing economy and estimated to grow between 6.8 and 7.2 per cent in the coming years. No doubt the need for energy is ever increasing. India’s per capita electricity consumption is at 1200 units as compared to the USA which is 12000 units. Energy is a growth engine for any economy. In such a situation, focusing on Energy Transition is quite crucial, with significantly long term financing for 15-20 years in place.
Navigating Upstream Challenges in Bioenergy Sector
Bharat is at the cusp of a Green Energy Revolution’; and Bioenergy, including Biofuels, is a vital Energy Engine’ to contribute towards the Net Zero 2070 commitment made by India during COP26. Surely, we will get there with collective efforts and partnerships, as we move into COP29 at Azerbaijan this year and beyond and one is sanguine that Bharat will not only lead the 2nd Industrial Revolution but also initiate and lead the Green Energy Revolution’.
Why Ensuring Adequate Biomass Supply is Fraught with Challenges
In recent years, biomass has emerged as a promising source of bioenergy, offering carbon neutral and sustainable energy. Sourcing and procurement of feedstock in India, however, presents unique challenges due to varying agricultural land, infrastructure constraints and economic conditions. Let's take a closer look.
Leveraging Bioenergy to Revitalise Indian Economy
From the early use of fire and animal power that improved lives, to the present world with use of electricity and cleaner sustainable fuels for a multitude of purposes - energy has been the enabler of development.
Can Bioenergy Adoption End Stubble Burning Practise?
Rice is one of the primary agricultural produces in India and a major source of sustenance.
Compressed BioGas: The New Hope for Energy Independence
The global bioenergy landscape is evolving rapidly, with countries around the world recognising its potential to address climate change, enhance energy security, and promote sustainable development. India, with its abundant biomass resources and growing energy demand, is uniquely positioned to lead in the bioenergy sector, particularly in the production and utilisation of Compressed Biogas CBG). Let's delve deep as to how CBG can be a new hope for energy independence for India.
Public-Private Partnership in Bioenergy Sector
Public-Private Partnerships (PPPS) represent a collaborative approach between government entities and private sector companies to achieve goals that neither party could easily achieve alone.
