Bioethanol is taking on a relevant role in the fight against climate change, thanks to its ability to reduce dependency on fossil fuels and his contribution to transition to renewable sourcesThis biofuel is used both as a gasoline additive and in fueling vehicles and heating systems, representing one of the most versatile tools to reduce Emissions of greenhouse gases.
In recent years, the European Union has strongly opted to incorporate bioethanol into traditional fuels, advancing the requirement for blends above 5%. This trend not only translates into a reduction in CO2 release, but also boosts the search for alternative raw materials that do not compete with the food industry.
Innovation: agricultural waste as raw material
One of the main challenges of development of biofuels such as bioethanol is to use waste that does not interfere with the food chain. In Spain, the University of Valladolid has investigated the utilization of apples from agricultural thinning and pruning remains for the production of bioethanol. These byproducts, previously considered waste, are collected and processed using enzymatic and distillation methods, achieving a bioethanol suitable for internal combustion engines.
This approach utilizes up to 2.000 tons of apples annually., along with some 250.000 kilos of pruning wasteAccording to experts, this model improves energy efficiency compared to other biofuels, while helping to meet the commitments of CO2 reduction set by the EU for 2030 and 2050.
Disruptive technology and investments in the chemical industry
La startup Catalyxx, from its headquarters in Andalusia, has developed a patented catalytic process that transforms bioethanol and agricultural waste into biobutanol and other industrial alcohols without resorting to fossil fuels, reducing costs and improving the environmental footprint of chemical production. Its internationally award-winning technology is backed by significant investment from the European Investment Bank to build the first industrial biobutanol plant in France and to strengthen R&D in the Andalusian region.
The Catalyxx method stands out for its Energy Efficiency and its ability to adapt to different agricultural waste, which has a positive impact on both industrial sectors and rural development and the creation of green jobs. In addition, the company has the support of European entities and seeks to position itself as a key player in the sustainable chemistry and advanced aviation fuels.
Business leadership and production strategies
Companies like Vertex Bioenergy consolidate Spanish leadership in the bioethanol production, with four plants in Spain and France and one capacity of up to 780 million liters per year. The company, which recently appointed Jorge Lanza as non-executive chairman, also produces derivatives for animal feed, green electricity, and captured CO2. Its strategic location allows it to meet demand in Southern Europe and the Mediterranean and support new lines of business linked to the energy transition, such as the development of biomethane and high-value-added refined alcohols.
At the forefront of these projects, Vertex seeks consolidate its role on the international scene through investments exceeding 300 million euros, focusing on diversification, sustainability, and innovation in biofuels.
Bioethanol in global markets
En Latin America, initiatives such as the sugar campaign of Tucuman, Argentina, reflect the growth of the industry. There, more than 65% of the sugar produced is used to make alcohol, with a significant portion transformed into bioethanol for blending with fuels. The region is experiencing increases in both sugarcane crushing and alcohol production and is seeking to increase the proportion of bioethanol in gasoline, following the example of countries like Brazil. Updated laws and a stable regulatory framework are essential to ensure the viability and sustainability of this sector.
En Mexico, the recent energy reform and the enactment of a new biofuels law They open the door to the development of bioethanol through the use of agricultural surpluses (sugarcane, sorghum, and corn). However, the country still relies heavily on imports and faces challenges in infrastructure, legislation, and the adaptation of service stations, which require considerable investment for their modernization. The potential is present, and there is consensus on the need for clear incentives and regulatory frameworks to attract capital and foster growth in the sector, although the local industry still has a long way to go to catch up with major global producers.
Changes in fuel composition and technical challenges
The arrival of fuels type E20, with 20% bioethanol, presents new opportunities and technical challenges. These fuels allow for a reduced carbon footprint, as the CO2 emitted during combustion corresponds to that previously absorbed by plants during their growth. However, high percentages of bioethanol may not be compatible with all engines, especially in older vehicles, and can lead to increased fuel consumption and the need to adapt components such as hoses, carburetors, and tanks.
The widespread use of bioethanol requires updating existing infrastructure, both in vehicles and at service stations, to ensure safety and optimal performance. Furthermore, the varying energy output and bioethanol's propensity to absorb moisture are factors to consider in fuel management and storage.
Bioethanol continues to establish itself as a fundamental piece in the energy transition, through the technological innovation, The revaluation of agricultural waste and cooperation between industry, governments, and research centers. Its development promises not only to reduce dependence on fossil fuels, but also to stimulate rural economies, generate green jobs, and promote a more circular and environmentally friendly chemical industry.
