My name is Anzeela Arjumand. I am studying in the Punjab university Lahore in the field of biochemistry.
“The renewable substance of plants, animals and microorganisms is called biomass.”
It is the primary source of chemical energy, i.e., heat; the other name for biomass is fuel. When plants absorb sunlight during the biochemical process of photosynthesis, it is used for various cellular reactions, including biomass production.
Biomass is a functional form of plants and animals and provides renewable energy to the environment on burning. Liquid biofuels and biogas are obtained directly from the burning of biomass. They provide fuels essential for generating electricity, run generators, motors, and other machinery.
Their energy densities are much lower than fossil fuels (other crucial raw materials). Biomass is an essential source of energy production as it acts as a raw material in various industrial processes to form a variety of products use in heating.
Biomass comes from the waste of plants, animals, crops, forests, farming, horticulture, humans and sewage plants, etc. Biomass chemical and functional properties vary, and so the potential of producing energy varies. The world’s largest biomass is located in BRAZIL, where it is present as 86% of the total.
Production of Biomass From Waste Water
Urban and rural wastewater treatment is a life project for producing biomass—the vertically tubular PBR (photobioreactor) prototype and measuring scale inserted in a wastewater treatment plant.
The production, quality, purification, and further uses of biomass are all done through PBR microorganisms. This treatment is quite helpful because the resulted purified water has values that can accommodate the environment. The maximum biomass energy of 89% can obtain by this process.
The production of biomass and biofuels from microalgae applications has increased due to their wide range of importance and advantages in this process. The wastewater acts as a media that provides culture enriched with minerals, nutrients, and other elements needed to grow microalgae. This ultimately increases the quantity of biomass.
Several techniques are valid for biomass production, but the most common and efficient method among them is “natural flocculent.” It produces high-quality biomass and increases its yield due to the absence of certain by-products. There is no toxin production in this method; thus, the biomass obtained is of good quality.
Advantages of Biomass
Biomass has a large number of advantages over fossil fuels (coal, oil, natural gas). These are as follows:
- Less expensive.
- Reduce environmental waste.
- Generate electricity with an identical power plant.
- A major source of biodegradable fuel use in industries.
- A large amount of the world’s energy is produced by biomass.
Disadvantages of Biomass
- It requires a large amount of space to store and process.
- To grow biomass crops, there is an excessive need for H2 O and land.
- It cannot even be adequately cleaned.
- % age of energy comes from biomass is more minor than fossil fuels.
- The primary source of deforestation.
- It releases toxins such as NO, CO2, CO, carcinogens that cause the greenhouse effect, global warming, and ozone depletion.
- If the release of carbon during burning increases, it leads to various chronic diseases, including asthma, lung cancer, heart diseases, and kidney problems.
- Biomass plants are expensive.
- The processed mechanism of biomass is much higher than fossil fuels.

Thank you so much.
