Today energy systems not only put pressure on natural energy resources which are nearly running down but also they involve an increase in the greenhouse gas emissions.

In the long term, through the genetic engineering development, the joint production of several profitable co-products (pharmaceutical and nutraceutical products, animal feed supplements, bioplatsics, etc.) and the link with other processes (such as the waste gas recovery and the wastewater treatment), it is expected, as well as the environmental sustainability, also the economic feasibility of the biodiesel production by microalgae.

Abstract
Today energy systems not only put pressure on natural energy resources which are nearly running down but also they involve an increase in the greenhouse gas emissions. After the development of the 1st and 2nd techniques of biofuels generation and considering the several issues bound up with their production, the attention is now shifting to the 3rd generation technologies, which use microalgae as feedstocks (since their main features are the high oil content, the high oil and biodiesel yield, the low land area needed). These technologies have been developed only in pilot plants (ponds or photobioreactors), with high capital expenditures. In the long term, through the genetic engineering development, the joint production of several profitable co-products (pharmaceutical and nutraceutical products, animal feed supplements, bioplatsics, etc.) and the link with other processes (such as the waste gas recovery and the wastewater treatment), it is expected, as well as the environmental sustainability, also the economic feasibility of the biodiesel production by microalgae.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
