Fermentation is used not only to produce alcohol but also in the production of acetone, butanol, and ethanol, for purposes such as the production of biofuels. The types of yeast and methods used in the fermentation process are constantly being refined in the interest of efficiency and sustainability, as explored in the facts below:

The success of acetone–butanol–ethanol fermentation – a process which uses carbohydrates such as starch and glucose to create acetone, butanol, and ethanol – relies on the choice of bioreactors

Currently, butanol – a substance used in biofuels – is extracted using a process which requires 220% of the energy produced by butanol itself, but methods are being developed to bring this figure below 10%

The most sustainable and environment-friendly way to produce butanol developed so far is through the microbial fermentation process

Saccharomyces cerevisiae yeast has frequently been used in the fermentation process over the course of millennia, and strains of the yeast are being investigated for second-generation ethanol production

Non-conventional yeasts are being considered as a replacement for Saccharomyces in bioethanol fermentation, as these are more tolerant to stress and might be more effective in the fermentation process

How are Biofuels a sustainable source of energy for global supply?

Biofuels are widely recognized as a sustainable source of energy because they are produced from renewable biological resources such as agricultural residues, used cooking oil, sugarcane, corn, and biomass waste. Unlike fossil fuels, biofuels help reduce dependence on finite energy sources and support long-term energy security.

From a biofuel supply and export perspective, sustainability begins with lower greenhouse gas emissions. Biofuels release significantly less carbon dioxide over their lifecycle compared to coal, petrol, and diesel. The carbon emitted during combustion is partially offset by the carbon absorbed during the growth of biomass feedstock, making biofuels a cleaner alternative.

Another key advantage is the use of waste and by-products. Export-grade biofuels such as biodiesel, bioethanol, biomass pellets, and briquettes convert agricultural and industrial waste into valuable energy. This reduces landfill waste while creating an additional income stream for farmers and processors.

Biofuels also support decentralized energy production, allowing exporting countries to supply stable fuel volumes without heavy reliance on crude oil imports. This makes biofuel exporters attractive partners for countries seeking reliable and cost-effective renewable energy solutions.

With rising global demand for clean energy, biofuels play a critical role in meeting sustainability targets. Their scalability, compatibility with existing infrastructure, and growing international trade make biofuels a practical and export-ready solution for the future of energy.

Bioethanol production from non-edible macroalgae collected in the waters of STA. ANA, Cagayan using microbial fermenters

The study determines the bioethanol production from selected non-edible macroalgae using different microbial fermenters. The bioethanol production included two processes; first involving acid pretreatment was carried out in this study to further degrade the complicated sugar present in macroalgae for seven (7) days. Second, anaerobic fermentation using four microbial fermenters. The result of the study showed that there were fifteen (15) species of macroalgae collected and identified. Among the fifteen non-edible macroalgae, the top ten with the highest percentage dry weight includes the three species of Halimedeae with Percentage Dry Weight (PDW) of 33 per cent, 27 percent and 24 percent for H. macrolaba, H. opuntia and H. tuna respectively. In terms of sugar content using Brix refractometer, the top five non-edible macroalgae species after pre-acid treatment were as follows: Liagora sp., Galaxaura oblongata, Sargassum crasssifolium with 3°Br; and Turbinaria oranata together with Padina japonica with 2°Br. The used of 30g/0.1kg dry weight sample among the five selected non-edible macroalgae utilized in the fermentation process yielded sufficient ethanol of 2.99 percent to 4.17 percent. Statistically, regardless of the non-edible macroalgae and microbial fermenter used in the study, there was no significant difference in their ethanol production. However, Liagora sp. showed the highest percentage ethanol production and the yeast microorganism Candida tropicalis was the best fermenter. Bioethanol from non-edible macroalgae such as the species of Liagora sp, G. Oblongata, S. crassifolium, T. oranata and P. japonica which were available.

What are the uses of biofuels in different industries?

Biofuels are becoming a preferred and sustainable energy source across multiple industries because they offer cleaner combustion, cost efficiency, and compatibility with existing machinery. Biodiesel is widely used in the transportation sector, powering trucks, buses, commercial fleets, and marine engines with lower emissions compared to petroleum diesel. Many industries also use biodiesel in diesel generators, ensuring reliable backup power with reduced carbon output.

In the manufacturing and industrial sector, biofuels such as biomass pellets and briquettes are used as a substitute for coal in boilers, furnaces, kilns, and steam generation units. These fuels provide steady heat, lower particulate emissions, and help industries meet sustainability targets.

Bioethanol is used in the automotive, pharmaceutical, food, and chemical industries as a cleaner-burning fuel and an eco-friendly solvent. It is also blended with gasoline in many countries to reduce carbon intensity.

The power and utility sector uses biofuels for co-firing in thermal power plants, helping reduce dependence on fossil fuels. Additionally, sectors like hospitality, textiles, ceramics, steel, and agro-processing benefit from biofuels for cost-effective heating and energy.

With growing global focus on sustainability, biofuels continue to expand their role across industries, offering a practical pathway toward cleaner energy use.
