Biomass as Renewable Source of Energy: Possible Conversion Routes
Biomass is renewable organic material that comes from plants and animals. Biomass was the largest source of total annual U. Biomass continues to be an important fuel in many countries, especially for cooking and heating in developing countries. The use of biomass fuels for transportation and for electricity generation is increasing in many developed countries as a means of avoiding carbon dioxide emissions from fossil fuel use. Biomass contains stored chemical energy from the sun. Plants produce biomass through photosynthesis.
Biomass is fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power. With a constant supply of waste — from construction and demolition activities, to wood not used in papermaking, to municipal solid waste — green energy production can continue indefinitely. Our facilities collect, process and recycle items for use as fuel, as well as green energy facilities that create power from that waste. Biomass power is carbon neutral electricity generated from renewable organic waste that would otherwise be dumped in landfills, openly burned, or left as fodder for forest fires. When burned, the energy in biomass is released as heat. If you have a fireplace, you already are participating in the use of biomass as the wood you burn in it is a biomass fuel. In biomass power plants, wood waste or other waste is burned to produce steam that runs a turbine to make electricity, or that provides heat to industries and homes.
Terrestrial lignocellulosic biomass has the potential to be a carbon neutral and domestic source of fuels and chemicals. However, the innate variability of biomass resources, such as herbaceous and woody materials, and the inconsistency within a single resource due to disparate growth and harvesting conditions, presents challenges for downstream processes which often require materials that are physically and chemically consistent. This increase in ash and reduction in lignin leads to biofuel conversion consequences, such as reduced pyrolysis oil yields for herbaceous products as compared to woody material. In this review, the sources of variability for key biomass characteristics are presented for multiple types of biomass. Additionally, this review investigates the major impacts of the variability in biomass composition on four conversion processes: fermentation, hydrothermal liquefaction, pyrolysis, and direct combustion. Finally, future research processes aimed at reducing the detrimental impacts of biomass variability on conversion to fuels and chemicals are proposed. Biomass is poised to make significant contributions to the domestic and carbon neutral production of fuels and chemicals.

Sources of Biomass Feedstock Variability and the Potential Impact on Biofuels Production
We may not realize it, but nearly all of us rely heavily on products derived from energy resources. Examples of such products include fossil fuel-based chemicals like plastics that are used almost everywhere in our daily lives. At present, most of our energy and petroleum-derived materials are made from nonrenewable resources, such as coal, petroleum, oil, and natural gas fossil fuels , because they have been historically available as primary products from long-established industries. However, for several reasons, there is a growing urgency to produce energy and related bio-based products from renewable resources. Firstly, fossil fuels will be depleted very quickly because they cannot be replaced or produced as fast as they are being consumed.
Biomass feedstocks include dedicated energy crops, agricultural crop residues, forestry residues, algae, wood processing residues, municipal waste, and wet waste crop wastes, forest residues, purpose-grown grasses, woody energy crops, algae, industrial wastes, sorted municipal solid waste [MSW], urban wood waste, and food waste.

Biomass is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops and waste from forests, yards, or farms. More often than not, the word biomass simply denotes the biological raw material the fuel is made of. The word biofuel is usually reserved for liquid or gaseous fuels, used for transportation. The U.
Energy Potential of Biomass Sources in Slovakia
Renewable energy has provided many potential benefits, including a reduction in greenhouse gas GHG emissions, the diversification of energy supplies, and a reduced dependency on fossil fuel markets oil and gas in particular. The growth of renewable energy sources RES may also have the potential to stimulate employment in the European Union EU , through the creation of jobs in new green technologies. In this chapter, first, we introduce the information on renewable energy sources, their statistics, and legislation background in Slovakia. In more detail, we further introduce the information on forest and agricultural biomass as a renewable energy source. In the experimental part, we introduce two case studies—the assessment of the potential stock of woody biomass and the determination of energetic properties of woody biomass, i.
People have used biomass energy ever since the very first cave-dwelling person thought to make a fire out of wood! Today, biomass power plants use everything from animal waste to wood pellets to create electricity. There are lots of advantages to biomass energy, which is a renewable energy source. Here at OVO, we chose to remove biomass from our fuel mix in , in favour of cleaner energy sources: wind , solar , hydro and tidal energy. Ready to learn more? Read on to find out everything you need to know about biomass and biofuels.
Energy from Organic Materials Biomass pp Cite as.
