If renewable feedstocks are used as a substitute for fossil raw materials, prices of all valuable alternatives start to correlate, as has been shown for the case of sugar, when it has been converted to biofuel. The argument that the prices of renewable feedstocks are relatively stable is only true, if they are not used for new applications, rising their demand. Therefore, new technologies should consider their impact on prices in the long run. Fossil-derived products lack the ecological and ethical dimension, since they are not CO2-neutral and their exploitation limits the opportunities of future generations. Biomass derived products such as sugar and starch for biofuels also entail certain ethical dilemmas, seeing that they are one of the main sources of food. A possible way to avoid this conflict would be the use of waste streams and non-edible biomass such as wood. Progress made in modern biotechnology is gradually increasing the possibility of converting lignocelluloses (cellulose and hemicelluloses) into fermentable sugars, when the food vs. fuel (or chemistry) discussion would no longer apply, at least superficially. In this context, it must be noted that food as such is not the limiting factor but arable land itself. Non-edible crops which could be cultivated on marginal lands would provide that best augmentations. On the other hand, additional processes for pretreatment would be necessary for lignocellulosic biomass which increases investment and utility consumption. Only if all the dimensions of a issue are favorable, will the production of products in the chemical industry be sustainable. Should white biotechnology further develop, a significant quantity of biofuels, bioenergies and also biochemicals would be made readily available. This would help the chemical industry to diversify their feedstock supply, even though they will be in direct competition with other branches and applications. Mirrored to fossil fuels, the chemical industry will have a greater access to biomass feedstocks, due to the higher added value involved. Currently, CO2-neutral production is fiction. Biotechnology and renewable resources will, however, contribute to future development towards CO2- neutral production systems
