Progress in Biofuels Production

We've been getting an onslaught of press releases from a number of it's great! cheap levitra from uk companies all promoting their biofuel production facilities and buy ultram canada the deals they are making to provide biofuels to various industries and markets. Numerous airlines and branches of the military have tested biofuels in their aircraft to verify it is safe to use. In many aspects, biofuels are a growing business.

However, despite the buy levitra wholesale flurry of production, biofuels are still a long way from replacing conventional fossil fuels. While the numbers can be impressively large-sounding, these still represent only a tiny percentage of the total amount of fuel that is consumed by motor vehicles annually. The output from a pilot plant may sound impressively large if thinking about the volume of fuel in comparison to how to get cialis in canada one's individual use. But when considered against the millions of vehicles on the road, it is completely dwarfed by the volume of fuel consumed annually (or even just daily) across the nation for transportation.

In addition, as part of brand name levitra the federal Renewable Fuel Standard, the EPA has recently set the http://www.karlbarth.nl/viagra-for-sale annual production volume target for bio-based diesel at 1.28 billion gallons, a volume which is levitra generic cialis in line with current industry production and capacity. The EPA rule does not mandate a particular percentage of biofuel to be incorporated into diesel fuels, but instead is an amount that industry is required to accommodate. This serves to guarantee a place for biodiesel in the fuel mix and is part of the Energy Policy Acts of 1992 and 2005.

According to the EPA, this use of biodiesel offers benefits to the nation, noting that "[q]uantified estimates of benefits include $41 million in energy security benefits and $19-52 million in air quality disbenefits." Additionally, there are likely to be direct and indirect employment benefits and GHG emissions reductions.

Biofuels are not a silver bullet solution, however, and there are a number of drawbacks to viagra soft generic many current forms of biofuel production. Unfortunately, many of the sources for biodiesel and only here cialis shop ethanol are competing with food uses of land and are using food crops like corn and soybeans as feedstocks for fuel. Rainforest lands are also being cleared for plantations of levitra 50mg sugarcane and jatropha that is being used for fuel. Despite these problems, in the long term, the growth of this industry can be useful in developing non-fossil fuels that can replace the current unsustainable fuel sources.

Volkswagen Pursuing Diesel Research

Volkswagen has announced partnerships with two manufacturers of biodiesel fuel as part of their ongoing work in developing diesel automobiles. The two companies are each receiving two VW diesel automobiles: a Passat TDI and a Jetta TDI, and they will each study how their fuels perform in these vehicles. The two companies, Amyris and Solazyme, will share the results of their research with VW over the 12-month period to help VW to "develop more efficient, cleaner burning diesel powertrains for future products."

Both companies are making biodiesel fuel with renewable materials as feedstock, instead of using petroleum. But the two companies are using different approaches to making fuel. Amyris uses a fermentation process to produce fuels from plant-sourced sugar feedstock. Solazyme uses an algae-based process, which also requires plant sugar feedstock, to produce its fuel. We've had both of these companies on our radar for the cialis online us]non generic cialis past few years, and they are both survivors in a startup industry that has seen a number of other players fall by the wayside.

Volkswagen is already a significant presence in the diesel portion of the passenger fleet in the United States. Although VW represents only about 2.5% of the US market, over 20% of that is with diesel automobiles.

Germany is Powering Cars on Food Scraps


A pilot project in Germany is collecting food waste from wholesale fruit and vegetable markets and buy levitra professional cafeterias to ferment and make methane, which will then be used to power vehicles that have been converted to www.velikibrat.us run on natural gas.

The pilot plant has been developed by the Fraunhofer Institute for Interfacial Engineering and Biotechnology and is located next to Stuttgart's wholesale produce market for easy access to food waste. The plant will make methane from the waste by using microorganisms to break down the food in a two-stage digestion process over a few days.

Because the food waste being fermented on any given day can be more or less acidic depending on www.asian-americans.com what was tossed out, the pH levels have to be constantly monitored in order for the microorganisms to best do their thing. The waste is held in several tanks that feature a management system that monitors many parameters, including pH level. The software then calculates how many liters of which waste should be mixed together to feed to the microorganisms.

The plant produces about two-thirds methane and one-third carbon dioxide from the process, but nothing goes unused:  the filtrate water which contains nitrogen and phosphorous, and the carbon dioxide produced from the fermentation are both used to cultivate algae for another project, while the sludge left behind from the fermentation is best prices on viagra in drugstores sent to http://www.way2age.com/buy-generic-levitra other institutes that are capable of making methane from it.

The pilot project has been funded by the German Federal Ministry of Education and Research and viagra 50mg online has partnerships with energy company Energie Baden-Württemberg, which is processing the biogas, and with Daimler, which is supplying natural gas-converted vehicles to run on the fuel.

Disadvantages of Aviation Biofuels

In the past couple of years, we've seen many, many tests being carried out by numerous different airlines and agencies to study the possibilities of using biofuel as an entire replacement for or as a blend with conventional jet fuel. But biofuels as a replacement for petroleum-based jet fuel may not be the http://www.supplychaincanada.com/viagra-soft-gel ideal solution.

Biofuels are better than straight petroleum-based products, but there are drawbacks to biofuels, as well. Dedicating cropland to buy cialis next day delivery grow fuel crops can cut down on the available land and farming resources for food production. There are arguments against algae-based fuels, as well. They don't compete with food for farmland, but the industrial infrastructure needed to produce algae-based fuel at scale is a daunting prospect.

Of course, conversion to any new material is a daunting prospect. The development of tramadol cats new technologies will eventually be necessary, one way or another. To continue to research alternatives and to find the best mix of feedstock for alternative fuels is importatnt not only for aviation, but for all energy technologies.

Virgin Atlantic, which is one of the many airlines to have tested biofuels, is now exploring a jet fuel replacement that, rather than using bio materials as feedstock, is derrived from waste industrial gas from steel production.  But if that relies on petroleum fuels as the original feedstock, then the long term viability of that process is also questionable.

Panda Poo Could be Key to Cheaper, Cleaner Biofuels


Scientists from Mississippi State University have discovered that panda poo could hold the answers to faster, cleaner and cheaper biofuels.

It has long been suspected that animals like pandas that each giant amounts of tough plant matter every day have bacteria in their digestive systems that are especially efficient at breaking down the cellulose in plants into nutrients. The hope is that those bacteria could make a big difference in the production of biofuels from tougher, non-food plants, like switchgrass, corn stalks and wood chips.  After collecting panda feces from the Memphis Zoo for over a year, researchers found that was definitely the case.

So far the cheap cialis online online scientists have identified several types of digestive bacteria from the feces. Some are similar to those found in termite feces, but the study has shown the bacteria in the panda feces could be even better at breaking down cellulose than those in termites.

Based on this study and others, the researchers believe that the panda gut bacteria could convert 95 percent of best price viagra australia plant biomass into simple sugars.  The enzymes in this bacteria are so potent that they can eliminate the need for heat, acids or high pressure processes in the manufacture of biofuels. Eliminating those processes would make biofuel production less energy intensive, faster and, of course, cheaper.

Researchers are working on identifying every bacteria present in panda intestines in order to single out the most potent of the enzymes.  Those enzymes could be put into yeasts through genetic engineering, which would allow for the mass production of those enzymes for the biofuel industry.
