Advanced biofuels refers to a subset of biofuels that can be produced from non-food feedstocks or waste materials. These biofuels are regarded as having lower emissions of greenhouse gases compared to traditional biofuels. In contrast to traditional biofuels, also known as first-generation biofuels, which are primarily derived from food crops like corn, soybeans, or sugarcane, advanced biofuels can be derived from a wide variety of non-food sources like agricultural wastes, algae, municipal solid waste, or wood chips.
Using advanced biofuels is a risk-free, tried-and-true, and scalable solution to reduce carbon emissions in the transportation industry, particularly in long-distance trucks and aviation. When compared to fossil fuels, the emissions that can be cut by using advanced biofuels range from 70% to 80%. It is generally agreed that advanced biofuels, as opposed to standard, first-generation biofuels, are more environmentally friendly.
Traditional biofuels often make use of “food-based” feedstocks, and these biofuels have garnered a lot of criticism for the fact that they redirect edible crops toward fuel production rather for food providing. Innovative biofuels make a contribution to the concept of a circular economy by making use of waste bio-feedstocks that would otherwise be thrown away in landfills and serve no other function. In addition, the utilization of refineries that are already in operation in order to manufacture renewable hydrocarbon fuels from the aforementioned bio-feedstocks is a method for lowering carbon emissions that does not require an excessive amount of investment in refinery infrastructure.
There are several types of biofuels, made from different feedstock and using different production methods, namely;
These biofuels are created from the cellulose and hemicellulose found in non-food crops and agricultural waste, such as maize stover, switchgrass, or wood chips. Cellulose is broken down into sugars, which are then fermented into ethanol or other fuels. This type of biofuel has the potential to minimize greenhouse gas emissions and can be created from waste sources.Baca Selengkapnya
