According to Kings Research, the global second generation biofuels market was valued at USD 12.32 billion in 2024 and is projected to grow from USD 15.00 billion in 2025 to USD 70.14 billion by 2032, registering a CAGR of 24.65% during the forecast period.
The rapid expansion of sustainable aviation fuel, renewable diesel, low-carbon transportation, and advanced ethanol technologies is creating significant opportunities for second-generation biofuel producers. Increasing investment in large-scale production facilities and improvements in biomass conversion technologies are also accelerating commercialization.
What Are Second Generation Biofuels?
Second-generation biofuels are advanced renewable fuels produced from non-food biomass sources. These include agricultural residues, forestry waste, municipal solid waste, algae, and dedicated energy crops such as switchgrass and miscanthus.
The production of these fuels generally involves advanced biochemical or thermochemical conversion technologies. Major products include cellulosic ethanol, biodiesel, bio-butanol, renewable diesel, and other advanced fuels.
A key advantage of second-generation biofuels is that they can reduce competition between fuel production and food production. They also enable the utilization of waste materials that might otherwise be burned, landfilled, or left unused.
The technology is particularly important for difficult-to-decarbonize sectors such as aviation, maritime transportation, heavy-duty road transportation, and industrial applications.
Rising Global Demand for Biofuels Drives Market Growth
The increasing global demand for cleaner transportation fuels is one of the primary factors driving the second generation biofuels market.
Governments and industries are establishing emissions-reduction targets, encouraging the development of renewable fuels that can reduce lifecycle greenhouse gas emissions. Airlines are also increasing their focus on sustainable aviation fuel as they seek alternatives to conventional jet fuel.
According to Kings Research, the International Energy Agency reported in January 2024 that global biofuel demand was expected to increase by 38 billion liters between 2023 and 2028, representing nearly a 30% increase compared with the previous five-year period.
This growing demand is encouraging energy companies and technology developers to invest in advanced biomass conversion, production facilities, and feedstock supply chains.
Sustainable Aviation Fuel Creates New Opportunities
The increasing demand for sustainable aviation fuel (SAF) is emerging as one of the strongest growth opportunities for second-generation biofuels.
Aviation is difficult to electrify at scale because of aircraft weight, energy density requirements, and long-distance operating conditions. As a result, sustainable liquid fuels are expected to play an important role in aviation decarbonization.
Second-generation feedstocks such as agricultural residues, waste oils, and other non-food biomass can be converted into fuels suitable for aviation applications.
Large-scale investments in SAF production are therefore creating new opportunities for biofuel companies. Producers are developing integrated facilities capable of producing renewable diesel and SAF from waste-based feedstocks.
In February 2024, Apical, through its renewable energy subsidiary Bio-Oils, began construction of a USD 1.28 billion second-generation biofuels facility in partnership with Moeve. The facility is expected to begin production in 2026 and produce approximately 500,000 tons of SAF and renewable diesel using agricultural waste and used cooking oils.
High Production Costs Remain a Major Challenge
Despite strong growth prospects, high production costs remain a major challenge for the second generation biofuels industry.
Converting lignocellulosic biomass into usable fuel is technically complex. Feedstocks such as agricultural residues and forestry waste contain cellulose, hemicellulose, and lignin, requiring specialized pretreatment and conversion processes.
Advanced enzymes, pretreatment technologies, specialized equipment, energy consumption, and complex supply chains can increase production costs. These factors can make second-generation fuels less competitive with conventional fossil fuels.
Companies are addressing this challenge through technological improvements, integrated production systems, process optimization, strategic partnerships, and economies of scale.
Reducing enzyme consumption, improving biomass conversion efficiency, recovering process energy, and developing low-cost feedstock supply chains are expected to remain key priorities.

The lignocellulosic biomass segment generated USD 6.31 billion in revenue in 2024, making it the leading feedstock category. Its strong position is attributed to its wide availability and effectiveness in producing cellulosic ethanol.
Lignocellulosic biomass can be sourced from:
- Agricultural residues
- Forestry waste
- Crop stalks
- Sugarcane residues
- Dedicated energy crops
- Other plant-based materials
The use of agricultural residues provides an important circular-economy opportunity. Instead of treating these materials as waste, producers can convert them into valuable renewable fuels.
Sugarcane residues are particularly attractive in countries with large sugar industries. In May 2024, Raízen launched a second-generation ethanol facility at its Bonfim Bioenergy Park in Brazil. The plant is designed to produce 82 million liters of second-generation ethanol annually from sugarcane residues.
Cellulosic Ethanol Holds a Leading Position
The cellulosic ethanol segment accounted for 57.32% of the market in 2024. The segment benefits from growing transportation fuel demand and compatibility with existing fuel infrastructure.
