Biomass is the oldest source of renewable energy and one of the most plentiful globally. It refers to biological material from living or recently living organisms that can be used as fuel. Biomass contains stored chemical energy from sunlight that plants absorbed, and this energy is released as heat when biomass is burned. Common sources of biomass include forestry and agricultural crops/residues, sewage, waste, and residues from animals and industry. Biomass can be used to generate electricity by burning it to produce steam that powers turbines, or to produce liquid biofuels or bioproducts. While biomass is a cheap and sustainable energy source, its use also faces challenges such as potential deforestation, pollution

Biomass - A Crucial Renewable Energy Source if Generated CorrectlyEES Africa (Pty) Ltd
Biomass is a renewable energy source derived from biological material, such as plants, wood and farming by-products. As an energy source, it can be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel.
Biomass energy has a dual effect, depending on where and how it is produced. If generated correctly it can be produced in ways that reduce global warming, as opposed to increasing it. It can help clean up the air, water, soil, and protect wildlife, or it can degrade lands, forests, water, and harm public health.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
2. Renewable Energy
Several countries have adopted ambitious plan to obtain their power from
renewable energy. They accelerating RE installations and integrating RE into their
existing infrastructure to reach a 100% RE mix. To many people, the most
familiar forms of renewable energy are the wind and the sun. But biomass (plant
material and animal waste) is the oldest source of renewable energy, used since our
ancestors learned the secret of fire.
Biomass is one of the most plentiful resources available globally, and demand for
it, is likely to increase substantially as the world looks to wean its dependence from
fossil fuels and on-going commitments to reducing greenhouse gases and
emissions.
3. Biomass and its process
Biomass is the biological material derived from living, or recently living organisms. It is
known as ‘natural material’. Biomass contains stored energy, in the form of chemical
energy - that’s because plants absorb energy from the sun through the process of
photosynthesis - as the plants died, the energy is trapped in the residue, so when biomass is
burned, this stored energy is released as heat.
In biomass, power plants, wood waste or other waste are burned to produce steam that
runs a turbine to make electricity, or that provides heat to industries and homes.
Fortunately, new technologies - including pollution controls and combustion engineering -
have advanced to the point that any emissions from burning biomass in industrial facilities
are generally less than emissions produced when using fossil fuels (coal, natural gas, oil).
5. Sources
• Forestry crops and residues.
• Agricultural crops and residues.
• Sewage.
• Municipal solid waste.
• Animal residues.
• Industrial Residues.
6. Biomass Energy technology applications
Biofuels: Converting biomass into liquid fuels for transportation. The two most
common types of biofuels are ethanol and biodiesel.
Biopower: Burning biomass directly, or converting it into a gaseous fuel or oil,
to generate electricity. Types of biopower systems: direct-
fired,cofiring, gasification, anaerobic digestion, pyrolysis, and small
modular.
Bioproducts: Converting biomass into chemicals for making products that
typically are made from petroleum.
7. EXAMPLES
Biomass can be used to produce
a variety of biodegradable
plastic.
Corn can be harvested to
produce ethanol.
8. EXAMPLE
Biomass is the largest source of renewable energy in Europe
Biomass alone accounts for 68.5 % of the renewable energy produced in EU-27, mainly in the
form of solid wood biomass for heating:
9. Advantages & Disadvantages
☺ It is a cheap and readily available source of energy.
☺ If replaced, biomass can be a long-term, sustainable energy source.
☺ Capable of being implemented at all levels of society.
☺ It can complement other renewables.
☻ Is only a renewable resource if crops are replanted.
☻ When burned, it gives off atmospheric pollutants.
☻ The use of wood and other plant material for fuel may mean deforestation.
☻ If not managed carefully, biomass can be harvested at unsustainable rates, damage ecosystems,
and consume large amounts of water.
10. Biomass Importance
Biomass energy resources are easily available in rural and urban areas of all
countries. Biomass-based industries can provide appreciable employment
opportunities and promote biomass re-growth through sustainable land
management practices.
When compared with wind and solar energy, biomass plants are able to provide
crucial, reliable baseload generation. Biomass plants provide fuel diversity,
which protects communities from volatile fossil fuels. Biomass power
greatly reduces our dependence on foreign energy sources and increases
national energy security.
11. General Conclusion
Every one of these power sources (with the exception of hydroelectric) has low environmental
costs, and combined have the potential to be important in avoiding a monumental crisis when
the fossil fuel crunch hits. These energy sources are often non-centralized, leading to greater
consumer control and involvement.
However, currently each of these energy forms is significantly more expensive than fossil fuels,
which will lead to economic dislocations and hardship if they become the only power source
for the future.
Biomass is an environmentally system very recommendable because it is a renewable, clean,
ecological, and at the same time is a fuel much cheaper than the natural gas, butane, propane or
diesel. Biomass helps to decrease volume of garbage and waste, since subsequent use is used
for energy production.
