Enviro-Pig
Is able to digest cereal grain phosphorus there is no need to supplement the diet with
either mineral phosphate or commercially produced photoset, and there is less
phosphorus in the manure. When the phosphorus depleted manure is spread on land in
areas of intense swine production there is less potential of phosphorus to leach into
freshwater ponds, streams and rivers. Because phosphorus is the major nutrient enabling
algal growth that is the leading cause of fish kills resulting from anoxic conditions, and
reduced water quality, the low phosphorus manure from Enviropigs has a reduced
environmental impact in areas where soil phosphorus exceeds desirable levels. Therefore
the environing biotechnology has two beneficial attributes, it reduces feed cost and
reduces the potential of water pollution. Furthermore, the technology is simple, if you
know how to raise pigs, you know how to raise Enviropigs!

Ethanol is a clear, colorless liquid with a characteristic, agreeable odor. In dilute
aqueous solution, it has a somewhat sweet flavor, but in more concentrated solutions it has a burning taste.
Ethanol,
Is a biofuel that helps cars go places and it helps out the Earth at the same time but it cost a lot of money.
to a carbon atom. The word alcohol derives from Arabic al-kuhul, which denotes a fine powder of antimony used as
an eye makeup. Alcohol originally referred to any fine powder, but medieval alchemists later applied the term to
the
refined products of distillation, and this led to the current usage.
Ethanol melts at –114.1°C, boils at 78.5°C, and has a density of 0.789 g/mL at 20°C. Its low freezing point has
made it useful as the fluid in thermometers for temperatures below –40°C, the freezing point of mercury, and for
other
low-temperature purposes, such as for antifreeze i automobile radiators.
Ethanol has been made since ancient times by the fermentation of sugars. All beverage ethanol and more than
half
of industrial ethanol is still made by this process. Simple sugars are the raw material. Zymase, an enzyme from
changes the simple sugars into ethanol and carbon dioxide. The fermentation reaction, represented by the simple
equation
C6H12O6
2 CH3CH2OH + 2 CO2
Biodiesel
– Biodiesel is the name of a clean burning
alternative fuel, produced from domestic,
renewable resources. Biodiesel contains no
petroleum, but it can be blended at any level with
petroleum diesel to create a biodiesel blend. It can
be used in compression-ignition (diesel) engines
with little or no modifications. Biodiesel is simple
to use, biodegradable, nontoxic, and essentially
free of sulfur and aromatics.
Methane Gas as Energy Source
• Methane is combustible, and mixtures of about 5 to 15
percent in air are explosive. Methane is not toxic when
inhaled, but it can produce suffocation by reducing the
concentration of oxygen inhaled. A trace amount of smelly
organic sulfur compounds (tertiary-butyl mercaptan,
(CH3)3CSH and dimethyl sulfide, CH3–S–CH3) is added to give
commercial natural gas a detectable odor. This is done to
make gas leaks readily detectible. An undetected gas leak
could result in an explosion or asphyxiation C2H6), and 5%
other hydrocarbons, such as propane (C3H8) and butane
(C4H10). The "firedamp" of coal mines is chiefly methane.
Anaerobic bacterial decomposition of plant and animal
matter, such as occurs under water, produces marsh gas,
which is also methane.
Plastic Products made from Corn
• The resin, known as polylactic acid (PLA), will be formed into
containers and packaging for food and consumer goods. The trendy
plastic has several things going for it. It’s made from a renewable
resource, which means it has a big leg up—both politically and
environmentally—on conventional plastic packaging, which uses an
estimated 200,000 barrels of oil a day in the United States. Also,
PLA is in principle compostable, meaning that it will break down
under certain conditions into harmless natural compounds. That
could take pressure off the nation’s mounting landfills, since plastics
already take up 25 percent of dumps by volume. And corn-based
plastics are starting to look cheap, now that oil prices are so high.
