Biomass energey from starch a good chance

Biomass feedstocks include:

1. 
   agricultural residues (straws, corn stalks and cobs, bagasse, cotton gin trash, palm oil wastes, etc.),
2. crops grown specifically for their biomass (grasses, sweet sorghum, fast growing trees, etc.),
3. paper (recycled newspaper, paper mill sludge's,
sorted municipal solid waste, etc.),
4. wood wastes (prunings, wood chips, sawdust, etc.),
and
5. green wastes (leaves, grass clippings, vegetable and fruit wastes, etc.).

The ability to utilize low cost feedstocks, and/or those that command tipping fees, to produce products that sell into highly efficient markets provides a viable business that can be sited in almost any geographic area, urban or rural. Due to its moderate use of thermal energy, the production of no waste streams, its significant environmental benefits, and minimal permitting requirements, the Technology also makes an ideal "thermal host" for cogeneration
facilities. This feed stock is excellent for xellulosic ethanol making.
A good technology was developed, you can see here

Eat plastic and drive on food

Profit is motion of every activity. Profit at any price is disaster. This title concern to something strange happen around us. Everyone has some small knowledge, or at least hear about biogas like solution for fuel. Few people go inside the problem.

Animal manure was centuries ago main resource for fertilizing land. Spread on fertile land on winter, wait for putrefaction, ridging the land in spring are elementary things known by all land farmers. Land cultivation is science. The main element which enrich the power of land is urea. As a consequence of industry growth, balance between number of animals, and land tilling decreased considerably.
New technologies use artificial fertilizer, produce in factories from row material gas, where they obtain nytrogen the main resource for urine thus produce different categories of land fertilizer.
Tilling grains, nourishing domestic animals we have as a final product instead of meat taste of plastic when eat.

Then if use animal manure for biogas production, and gas for land fertilizing you can properly tell: eat plastic and drive on food.
As a result of profit at any price.

Bio Energy Myths

Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugar cane, and many other byproducts from a variety of agricultural processes. Bioenergy is Renewable Energy derived from biological sources like plants, can be used for heats, electricity, or as fuel in vehicles. Its production for fuel has bad implications for agriculture. It also can be used in gasoline blends. In USA most biofuel is ethanol, and is produced from corn. What could sources for ethanol? It is grain general, corn especial, sugar can, sugar beet, switch grass (for cellulosic ethanol), fruits and all bioproduces which contain sugar. Disadvantage of every renewable source of energy is that you must consume energy to produce it in classic form of use. Now lets see corn like source of ethanol. Heavy demand for ethanol guide to higher prices for corn. The result is reduction in corn used for livestock feed, the largest use of corn. Reduction of the exported amount very important for global markets. Result is that retail food prices are projected to increase. Result is that retail food prices are projected to increase.
Conclusion is that production of ethanol has an serious impact on agricultural and food sector.
