A group of Spanish developers working under the company name Ecofasa, headed by chief executive officer and inventor Francisco Angulo, has developed a biochemical process to turn urban solid waste into a fatty acid biodiesel feedstock.

Here is a translated description of the tecnology:

ECOFA is a new fuel, which due to its origin, its production, and its solution to the inherent problems in any kind of organic waste, specially the urban solid waste, it is called 'eco.combustible' adding FA (initials of Francisco Angulo) in honor of its discoverer.

Ecofa biofuel is a subgroup of biofuels that comes from fatty acids biosynthesized from microbes and to used it in current internal combustion engines and diesel

It is based on the metabolism's bionatural principle, by mean of which all living organisms, including bacteria, produce fatty acids. The great contribution of Francisco Angulo's patents, this is why its incalculable economic value, is exactly that this principle is used to the biofuel's production and comes from the carbon of any organic waste.

The microorganisms that synthesize useful products for men represent, at most, a few hundred species among the more than 100,000 described in Nature. The few that have been useful for industry are valuated for procuding a substance that can not be achieved easily or cheaply by other methods. Next it is going to be explained the advantages that ECOFA has with regard current biodiesel:

  • Almost the whole solution to the problem that exists in municipalities with the treatment and storage of domestic rubbish. Moreover, the process produces methane gas and  it is also left a remain that could be used as organic fertilizer for fields.
  • It would not be necessary to used specific fields of maize, wheat, barley, beets, etc.. which would remain for human consume without creating distortions or famines with unforeseeable consequences.
  • So, it would be possible that farmers had to use less plowing , so the field could recover, in a natural way, the lost carbon ( agriculture's conservation).
  • The monocultures's productions are always more favourable to pests, as it is not spread (because it is not only used to biodiesel ) the risk is lower
  • Possibility for town halls of the autonomous processing in its own plants that will generate and will bring wealth to rural populations. The production would be mainly in consumption's towns, so it would not be necessary  pipelines, nor ships sailing with cargo that could be poured into the sea, since the producing plants are not very complex nor expensive and any town can install it without too much complications.
  • According to the environment, the use of  RSU (Solid Urban Waste) for energy production, is expected to present some added benefits of those that already exist in biofuels. Particularly with regard to smells, the improve of the landscapes and the reduction of pollution in the air, water and soil.
  • Finally this microbial technique can be extended to other organic debris, plants or animals, such as those contained in the urban sewage. You can even experiment with other materials such as carbon sources, and this opens up a lot of possibilities; it is only necessary to find out the appropriate bacteria and make them work as a huge army of workers without pay, eating letfovers without stopping, as they reproduce by cloning and therefore bringing more and more quantity of ecocombustible.


ECOFA by their origins, already would represent a first relief to three problems that we suffer nowadays:

  • urban solid waste, that would benefit mainly the town halls which have to suffer the logistical problems
  • contribution of its share to the supply of the general fuel's demand .
  • and contribution of its share to the solution of climate change problem

But there are also other connotations as important:

  • Its production does not cause famine, on the contrary it would generate wealth in the areas of production. Town halls would be again favoured
  • As biotechnology takes part in it, and the yeasts and bacteria produce the process, it does not require the input of energy or heat, that others need, so it is also highly worthwhile in terms of its energy balance. Bacteria do not consume energy from others while they are working
  • As the biotehconology is the responsible, bacteria and yeast, due to their metabolism, produce fatty acid from any carbon source, including all the organic waste, since it can be done at any stage with the appropiate bacterium: sewage, waste of slaughterhouses, remains and stubble of the field, paper, gauze and cotton (from hospitals, for example) and any other organic waste.
  • It is not renewable but multirenewable, since (CO2) that comes from its combustion, leads to the growth of any kind of plants which they do not have to be used to produce biofuels, they might also come in useful for a food cycle and / or biological, leading to organic debris of any kind.
  • It is also multisustainable. Obviously, this is due to the diverse origins of organic waste, the logistics of   ECOFA' s raw material , can come from any rubbish and from any place on the planet.


The origin is in some patent, whose owner is Francisco Angulo Lafuente, that support biotechnological processes in order to achieve a fuel from remains and organic waste.
