3 Things You Need To Know About Bioproducts With the increasing discussions about the environment and how human behaviour and practices are having a negative impact on the environment, we all must ... have heard about the “bioproducts” at least once. In this blog, I will be talking about that same elephant in the room. So here are 3 things that you need to know about bioproducts: What are Bioproducts? Bioproducts are products composed with biological or biorenewable resources. The “bio” in bioproducts refers to biological resources like trees from forests and agricultural crops. Bioenergy is the most common thing that we obtain from bioproducts. We all know and understand the use of trees as a source of bioenergy since we can easily burn the wood but what about crops? Sugars are the most important material when it comes to bioenergy. Human beings and other animals respire to release energy from sugars (E.g. Glucose) in the presence of oxygen. These sugars are made in plants by photosynthesis, by using carbon dioxide, water, and energy. The energy used by plants for photosynthesis is stored in sugars (like starch) which can be used later. Similar to respiration, combustion is burning of carbon containing products in the presence of oxygen to generate energy. Sugars or carbon containing products (E.g. Hydocarbons) are obtained from plant sources which can be used to make bioproducts that is used to generate bioenergy. How are Bioproducts made? The few most commonly used bioproducts are ethanol, used as fuel for energy, oils from plants, used as fuel or lubricant and as an ingredient for cooking, and bioplastics, used as packaging material. The major components of all these products are made from biological materials. Ethanol is produced by the fermentation of plant based sugars. Fermentation is a process which converts sugars into ethanol and carbon dioxide, in the absence of oxygen with the help of microorganisms like yeast. The yeast fungus anaerobically respires to grow in number while also producing ethanol. The ethanol produced is later mixed with gasoline [Show More]
