  1. Biomass By: Christina, Angel, Kathleen, Yscilla, Jasmine

  2. What is Biomass? Renewable energy source A biological material from living, or recently living organisms Can be used directly, or converted into other energy products such a biofuel. Derived from five distinct energy sources: garbage, wood, waste, landfill gases, and alcohol fuels.

  3. Source of biomass

  4. Use of biomass • Biomass used for electricity production ranges by region. • Forest by-products, such as wood residues, are popular in the US. Agricultural waste is common in Mauritius (sugar cane residue) • Animal husbandry residues, such as poultry litter, are popular in the UK.

  5. Plants & animals Biomass is plant matter used to generate electricity with steam turbines or produce heat, usually by direct combustion. Examples are forest residues (like dead trees, branches and tree stumps), yard clippings, wood chips and municipal solid waste.

  6. Biomass includes plant or animal matter that can be converted in fibers or other industrial chemicals including biofuels. Industrial biomass can grow from many kinds of plants: Miscanthus Switchgrass Corn Willow Sugarcane Variety of tree species Eucalyptus to oil palm (palm oil).

  7. Waste energy • Waste energy is the second largest source of biomass energy. • Main contributors of waste energy are municipal solid waste, manufacturing waste, and landfill gas. • Biomass alcohol fuel, or ethanol, is derived primarily from sugarcane and corn. It can be used directly as a fuel or as an additive to gasoline.

  8. Can biomass be changed? • Biomass can be changed into other usable forms of energy like methane gas or transportation fuels like ethanol and biodiesel. • Rotting garbage, and agricultural and human waste, release methane gas (landfill/biogas). • Crops like corn and sugar cane can be generated to produce ethanol. • Biodiesel can be produced from leftover food products like vegetable oils and animal fats

  9. Is it really environmentally friendly? • Biomass as fuel produces air pollution in the form: • carbon monoxide • nitrogen oxides • volatile organic compounds • particulates and others…

  10. Use of biomass in US • Biomass power generate industry in the US produces about 1.4% of the US electricity supply • The New Hope Power Partnership is the largest biomass power plant in North America. • Facility uses sugar cane fiber (bagasse) and recycled urban wood as fuel to generate enough power for its large milling and refining operations • Supply renewable electricity for nearly 60, 000 homes • Recycling sugar cane and wood waste, it preserves landfill space in urban communities in Florida.

  11. Wood Energy • Wood energy is derived both from direct use of harvested wood as a fuel and from wood waste streams. • Largest source of energy from wood is pulping liquor or “black liquor,” a waste product from processes of the pulp, paper and paperboard industry.
