All countries world wide share the same problem: acummulation of different types of waste. For the most part, this waste is usually linked to some kind of air pollution and water contamination. Fortunately this waste has an energy value that allows us to recover its energy becoming a real alternative to reduce our dependency to fossil fuels.
Technologies such as gasification and pyrolysis are the answer to turn waste with no value, into important raw material to generate electricity, biofuels and fertilizer.
Pyrolysis is the thermo-chemical decomposition of organic materials in an Oxygen free environment. In most cases, this process generates gas and liquid products leaving a solid byproduct rich in carbon content. The gas is known as “Syngas” which, under proper conditions, can be used as fuel to produce steam or to feed a gas turbine or an internal combustion engine to generate electricity. The oil known as “Pyrolysis Oil” is also a valuable product since it can be refined and transformed into lubricants and diesel fuel among other products.
Gasification is a process that converts carbon-containing materials into syngas using high temperatures with a controlled amount of Oxygen, air or steam, still without allowing combustion to take place. The syngas produced by gasification is exactly the same as the one produced by pyrolysis and it has the same uses. In addition, syngas can be converted to synthetic fuel, being “Fischer Tropsch” probably the most popular process.
