  1. Alternative Energy Forest Products and Residues What do we have? How can we use it? http://www.bionomicfuel.com/how-does-cellulosic -ethanol-production-work/ http://www.panoramio.com/photo/44421156 http://www.smartinnova.com/index.php?p=re-gasify http://planetearth.nerc.ac.uk/news/story.aspx?id=361

  2. Harvesting for Cellulosic Residues (La cosecha de los biocombustibles celulósicos) Pros Cons Transportation of harvest Possible mass-farming and clear-cutting Harvesting would have to occur before pay-off Some farmers will need to have set-aside land As difficult as encouraging recycling • Doesn’t require diverting the use of cropland • Can be made from non food plants • Creates jobs for the harvesters and those building the plant and working in it • Renewable (if done correctly)

  3. Biomass and Burning Old ideas New perspective

  4. Cellulosic ethanol What is it? Is a renewable energy resource used as transportation fuel as one of the alternatives to petroleum from the cellulose in plant biomass (Kumar and Murthy,2011). • What is the cellulosic ethanol made from? • Materials such as: • Wood • Grasses • Wastes How is cellulosic ethanol made? Is cellulosic ethanol a good Idea? The answer could be No, but also Yes. No : -High deforestation -Further expansion of monoculture tree plantations Yes: -Operation in small-scale- The main raw materials used could be waste- Based on locally available resources Source: http://ethanol.yolasite.com/process.php
