The main advantage of using biomass and bioenergy is as a renewable and environmentally friendly energy source. Biomass can be renewed through the process of photosynthesis and has a carbon neutral impact because the amount of carbon released during combustion is proportional to the amount of carbon absorbed by plants during their growth. Biomass is organic material that can be used as an energy source. Biomass sources can come from various sources, such as plant remains, agricultural waste, food waste, industrial waste, or even marine biomass. Biomass can be converted into bioenergy through thermochemical or biochemical processes. Biochemical processes involve the breakdown of biomass by microorganisms under anaerobic or aerobic conditions. Anaerobic processes produce biogas, while aerobic processes produce heat or electricity through combustion. Biogas is a gas mixture of methane (CH4) and carbon dioxide (CO2) produced from the decomposition of organic wastes such as agricultural waste, food waste, or animal waste. In addition, the use of biomass also helps in managing organic waste, reducing dependence on fossil fuels, and reducing greenhouse gas emissions. Biomass also has the potential to increase agricultural sustainability and promote local economic development. In thermochemical processes, biomass can be converted into solid, liquid, or gaseous fuels through processes such as pyrolysis, gasification, or combustion. Examples of thermochemical biomass fuels include charcoal, wood pellets, bioethanol, biodiesel and biogas. 14 2.4 Biomass and ionenergy fuels Machine Translated by Google
15 However, the use of biomass and bioenergy also faces several challenges. One of them is the availability and diversity of biomass sources. Ensuring a sustainable supply of biomass and avoiding the use of biomass sources that have the potential to damage the environment or food balance are important factors. In addition, biomass conversion technology also requires significant development and investment. The efficiency of the biomass conversion process needs to be increased so that bioenergy is more economical and competitive with fossil fuels. In order to optimize the use of biomass and bioenergy, it is important to take a holistic approach, taking into account environmental, social and economic aspects. Appropriate regulations, continuous technology research and development, and awareness of sustainability are the keys to utilizing biomass and bioenergy in an effective and sustainable manner.
