The upcoming jet fuel.. Could it be produced from "sugarcane waste"?

SadaNews - A joint research team from the University of Queensland in Australia and the Indian Institute of Technology in Delhi has successfully developed a new method to convert sugarcane waste into aviation biofuel in a more environmentally friendly and cost-effective manner.

The study, published in the journal "Biofuels, Bioproducts and Biorefining," demonstrated the feasibility of simplifying the processing of sugarcane residues, known as "bagasse," using a biodegradable solvent called "deep eutectic solvents," instead of conventional expensive and polluting acids.

These solvents are environmentally friendly liquids made by mixing two solid materials to form a liquid at a low temperature, which allows interaction with agricultural waste without the need for toxic acids or large quantities of water.

The major advantage of these solvents is that they do not destroy the enzymes and yeast required to convert sugars into biofuel, streamlining the process into a single step and saving time and energy. Thanks to this technique, sugarcane waste can be transformed into sustainable biofuel for use in aircraft, while reducing the environmental impact of the traditional burning of waste in the fields.

Addressing Key Challenges

This technique addresses one of the major challenges in biofuel production, which is the presence of lignin that hinders access to fermentable sugars.

Unlike traditional methods, the new approach allows for the entire conversion process to be performed in one step, without the need for separation or the use of large quantities of water, thereby reducing energy consumption and time.

The results also showed that selecting sugarcane varieties with high cellulose content and low lignin increases the efficiency of producing bioethanol. Models indicate that integrating this technology with sugar mills could make biofuel production more economically feasible and environmentally sustainable.

Researchers hope that these findings will contribute to better uses for agricultural waste, especially in countries suffering from its burning and the resulting air pollution, thereby enhancing global efforts to combat climate change and accelerate the transition to alternative energy sources.
