What is biofuel, and how to make it?
More and more renewable energy sources or those that do not pollute the environment are being developed. We must keep in mind that changing the existing energy model becomes more difficult overnight. Therefore, we are immersed in the so-called energy transition. One of the elements contributing to the reduction of pollution is biofuels Rashtriya Jaiv Indhan Niti We can intuitively understand what this entails, nothing but the name. However, many people do not know what they are made of, what they are for, and what advantages they offer over conventional fuels.

Were you interested in learning more about biofuels? In this article, we will explain everything in detail.

What is biofuel

Biofuels are also known as biofuels. Mixtures of substances of organic origin form these compounds. These substances are used to generate energy. This is considered renewable or cleaner energy since the imports come from biomass. Consequently, this organic matter, which arises and accumulates, can be renewed over time.

There is controversy over the balance of CO2 emissions and CO2 uptake by this biofuel. Since the substances that make up this compound are organic, they absorbed CO2 during photosynthesis during their life. When they finish their lives, they are used to generate this fuel. Unlike other renewable energy sources such as solar, this biofuel also creates carbon dioxide emissions. A balance is calculated between the CO2 emitted during its use and the CO2 absorbed during the production of organic materials (plantations).

It has been argued that the balance is positive so that less CO2 is emitted when used than when it is formed.

The advantage of these Jaiv Indhan Niti 2018 is that they can replace much of the consumption of fossil fuels. This reduces their impact and reduces greenhouse gas emissions worldwide. Although the emissions from both fuels are the same, CO2 is not absorbed during oil formation, as is the case with biofuels.

What are they made of

Now we will get acquainted with the types of plants from which. Can produce biofuels. Many people think that this is a waste of land, over-exploitation of land in agriculture, and food waste. You have to think about what food is being used. The remaining food is used to form biofuels.

Plant species used include:

• soya beans
• Corn
• Sugar cane
• Cassava
• Sunflower
• Eucalyptus
• palm trees
• Los Pinos
• Algae oil

These biofuels can be divided into three large groups depending on the raw materials used in the production process. There are first, second, and third-generation biofuels. We are going to analyze each of them:

• Biofuels of the first generation. These come from crops that are used to produce food for human consumption. These production systems are the simplest as they use leftovers from the production of these products. Plus, they're cheaper. However, it does have some limitations that may endanger food supply and biodiversity due to the reduction of plant species in ecosystems.
• Biofuels of the second generation. This type of fuel is due to the high demand for biofuels. It is obtained from biomass produced in the forest environment. These materials are lignocellulosic and their natural woody or fibrous materials. It is a biofuel that continues to reduce CO2 emissions but is more expensive and more difficult to produce than the first generation. They are made from products not intended for human consumption or are waste.
• Biofuels of the third generation. They come from biomass that is not intended for human consumption or waste. In this category, we include microalgae. Molecular biology techniques are used in its production, and microalgae can be created for the subsequent production of biofuels.
Types of biofuels

We are going to analyze the different types of biofuels that are most known and used by everyone:

• Bioethanol. This is the one that is formed from the alcoholic fermentation of sugars present in some plant species. We can find sugar cane, beets, or some cereals among these species.
• Biodiesel. It is made from vegetable oils, including soybean oil, rapeseed, and jatropha. These species are grown for use as biodiesel.
• Biopropanol or biobutanol . These two types are less popular but are currently being researched as . may use them just as often as the previous two.

Advantages and disadvantages

While they may seem like a lifesaver, they have both advantages and disadvantages. Let's list the benefits:

• The cost will be less than that of gasoline or diesel. Raw materials are practically absent, as they are waste.
• This creates jobs locally.
• They reduce emissions.
• More efficient production processes and less pollution.
• It has a higher level of security when handled.

But not everything can be an advantage. Let's list the disadvantages:

• Using nitrogen fertilizers for crop production increases nitrogen oxide emissions and pollutes water and soil.
• They give less energy than regular ones.
• Loss of forest area for crops and these species are CO2 consumers.
• Fossil fuels are used to produce some biofuels, further increasing emissions.

I hope that you can learn more about these alternative energy sources that are causing controversy as to whether they are truly sustainable or not and that their use should increase in society.
