My name is Anzeela Arjumand. I am studying in the Punjab university Lahore in the field of biochemistry.
Advantages of Biomass
“The renewable substance of plants, animals and microorganisms is called biomass.”
It is the main source of chemical energy i.e. heat, the other name for biomass is fuel. When sunlight is absorbed by plants during the biochemical process photosynthesis, it is use for various cellular reactions including the production of biomass.
Biomass is useful form of plants, animals and provides renewable form of 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 important raw material). Biomass is an important source of energy production as it acts as 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 total.
Production of Biomass From Waste Water
The treatment of urban and rural wastewater is a life project for producing biomass. The vertically tubular PBR (photo bioreactor), prototype and measuring scale inserted in a wastewater treatment plant.
The production, quality, purification and further uses of biomass are all do through microorganisms of PBR. This treatment is quite helpful because the resulted purified water has values that can accommodate 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 for the growth of microalgae. This ultimately increases the quantity of biomass.
There are several techniques use for the production of biomass 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 large number of advantages over fossil fuels (coal, oil, natural gas). These are as follows:
- Less expensive.
- Reduce environmental waste.
- Generate electricity with same power plant.
- Major source of biodegradable fuels use in industries.
- Large amount of world’s energy is produce by biomass.
Disadvantages of Biomass
- It requires large amount of space to store and process.
- To grow biomass crops, there is an excessive need of H2 O and land.
- It cannot even cleaned properly.
- % age of energy comes from biomass is less than fossil fuels.
- Major source of deforestation.
- It releases toxins such as NO, CO2, CO, carcinogens that cause greenhouse effect, global warming and ozone depletion.
- If the release of carbon during burning increases, it leads to various chronic diseases including asthma, lungs cancer, heart diseases and kidney problems.
- Biomass plants are expensive.
- The processed mechanism of biomass is much higher than fossil fuels.
