"GREEN" VS "NATURAL" CHEMICAL PRODUCTS

It has been known that there is a great difference in the market between "organic" and common vegetables; specially in price!! But what is really an organic or totally natural vegetable, and how is this related to chemical products??
Well by definition a totally natural material is one that has not been contaminated or transformed by any additive or process derived from human source. So if an apple is washed with soap, or washed with chlorinated water, or waxed, is then not natural and if it is collected and processed by a machine, then it is not natural by definition. So if a natural soap which is derived from coconut oils, oleic acid, glycerin and soda is reacted in a reactor and finally filtered, then would not be considered natural. I think that is not fare; since we should really qualify them as natural based on their biodegradability and their re utilization potential, in addition to the safety of use that they represent
Another great topic of concern is the use of "green bio-fuel".
It is known that everybody is now concerned with the environment and the reduction on the use of synthetic and hazardous materials, via the formulation of chemicals that will not harm the environment and are safer to use.
See constant issues and advances on this topics in http://www.icis.com/blogs/green-chemicals/ and in www.icis.com/blog for advances in chemical news. In the April 2008 issue of the publication HAPPI, see at: www.happi.com, we can see the advantages and disadvantages of the use of renewable resources as crops and other vegetables, as a substitute for hydrocarbons derived from the petrochemical industry; also the resolution of some big chains like Wall-Mart are requesting their supplier to provide green products.
The final concern is that even though the use of bio-fuels is practically a need due to lowering availability of oil with time, and its negative effect on the environment, also is very true that the use of crops will reduce its availability for human and animal nutrition and will also require more energy feed to transform them in alcohols or other fuel additives.There has also been concern on the volatile emissions of these bio-fuels into the environment, once they are used as fuel.
One thing seams to be true and this is that there will be no cost reduction on the use of crops as alternative fuel feeds. Methanol from garbage digestion seams to be a good alternative but is less viable due to the extent of conversion and efficiency.
