What is SAF?

SAF stands for Sustainable Aviation Fuel. It is produced by agricultural waste, solid waste and other forestry residues. These bio-waste materials are used in the SAF production facility as feedstock and the bio-zet fuel is produced. It is safer and more efficient than conventional jet fuel in terms of carbon emission and sustainability. The low sulfur of bio-jet fuel or SAF reduces the pollution from the environment and the use of waste material decreases the carbon footprint in comparison to the conventional fuel manufacturing process. India is leading the aviation sector globally to shift from conventional fuel sources to SAF.

Why is the SAF (Sustainable Aviation Fuel) important?

Climate change and global warming are pressing environmental challenges that result from the increase in greenhouse gas emissions, primarily carbon dioxide, methane, and nitrous oxide, trapping heat in the Earth's atmosphere. The aviation sector plays a substantial role in contributing to these issues. Aircraft emit significant amounts of carbon dioxide and other pollutants during their operations, releasing them directly into the upper atmosphere where their impact on the greenhouse effect is more potent. The combustion of aviation fuels, particularly jet fuel, releases not only carbon dioxide but also water vapour, contrails, and black carbon, further intensifying the sector's climate impact. The aviation industry's continuous growth, along with the lack of viable low-carbon alternatives for long-haul flights, poses a considerable challenge in mitigating its environmental footprint. Efforts made towards the shift to SAF are extremely important to deal with these global issues.

How does the use of SAF in the Aviation Sector Benefit the Environment?

The use of Sustainable Aviation Fuel or Bio-Jet Fuel brings many benefits to the aviation sector and helps the environment to sustain longer with healthy industrial practices. Some of the major benefits are as follows-

• Greenhouse Gas and Climate Change

One of the primary advantages of sustainable aviation fuels is their potential to significantly reduce greenhouse gas emissions compared to traditional aviation fuels. SAFs can be derived from renewable sources, such as biofuels or synthetic fuels produced using renewable energy, resulting in lower carbon footprints. Sustainable aviation fuels have the potential to mitigate the climate impact of aviation by reducing emissions of carbon dioxide, as well as other pollutants, such as sulfur oxides and nitrogen oxides. This can contribute to efforts to combat global warming and improve air quality.

• Diversification of Fuel Sources

Relying on a variety of feedstocks for sustainable aviation fuels, including biomass, algae, and waste, allows for a diversification of fuel sources. This reduces dependency on fossil fuels and enhances energy security by creating resilience and facing the fluctuation of oil prices and disruptions in the supply chain.

• Job Creation and Economic Opportunities

The production and use of sustainable aviation fuels can stimulate economic growth by creating jobs in the renewable energy and biofuel industries. It fosters innovation and investment in sustainable practices, contributing to a more robust and resilient economy.

• Technology Advancements & Global Collaboration

The development and adoption of sustainable aviation fuels drive technological advancements in fuel production and aircraft technology. This, in turn, encourages the aviation industry to invest in more fuel-efficient and environmentally friendly aircraft. The use of sustainable aviation fuels promotes international collaboration and cooperation to address the aviation sector's environmental impact.

• Public Perception and Corporate Responsibility

Adopting sustainable aviation fuels aligns with growing consumer and corporate preferences for environmentally responsible practices. Airlines investing in sustainability may benefit from positive public perception and enhanced corporate responsibility, potentially attracting environmentally conscious travellers and investors.

Demand and Supply of Feedstock - The Crucial Factor

The demand and supply of feedstock for Sustainable Aviation Fuel (SAF) are critical. Foreign investors offering high prices for Indian feedstock jeopardise domestic SAF production. Government policies regulating biowaste markets are needed to ensure domestic availability without harming farmers. Agricultural waste is a key feedstock, but challenges include the need for more infrastructure for SAF-appropriate materials. Despite a substantial pool of used cooking oil and animal fat, much is exported at higher prices, compromising domestic availability. However, there's optimism that existing biomass and waste can meet SAF demands, minimizing the need for fresh cultivation. Addressing these challenges requires efficient collection mechanisms and policies balancing domestic and international feedstock demand.
