BIOGAS

How does it work? It uses trash to transform in different energies like electric power. Utiliza la basura para transformarla en diferentes energías como la energía eléctrica.

Where can you find “plants” of this source and why? You can find “plants” of this source in places where there is a lot of organic waste, because this waste releases biogas which is burnt to produce heat and there from energy. Puedes encontrar “plantas” de esta fuente en los lugares donde hay gran cantidad de residuos orgánicos, ya que estos desechos libera el biogás que se quema para producir claor, y de ahí, la energía.

Can it be used in Spain, why/why not? Yes, it can be used, because it’s a very conscious country and because they recycle thrash. Sí, se puede utilizar, porque es un país muy concienzudo y porque reciclan la basura. Is it expensive? No, because the energy comes from the waste. No, porque la energía proviene de los residuos. What is the effect on the enviroment? It’s a positive effect because it eliminates the organic waste, that people sees like a problem, to create energy. Es un efecto positivo, ya que elimina los residuos orgánicos, que la gente ve como un problema, para crear energía. Are you dependent of other countries/people when you want to generate electricity with this energy source? No. Waste is available everywhere. No. Los residuos están dsponibles en todas partes. How much electricity is generated in one plant? Each cubic meter (m3) of biogas contains the equivalent of 6 kWh of calorific energy. Cada metro cúbico (m3) de biogás contiene el equivalente de 6 kWh de energía calorífica. What are the advantages and disadvantages of this energy source? The advatages are:

  1. Reducing trash volume up to 90%.
  2. Energy recovery.

The disadvantages are:

  1. If you burn the trash without separeting, it ca produe highly toxic produts.
  2. The ash combustion products containing heavy metals should receive special treatment.

Las ventajas son:

  1. Reducir el volumen de la basura hasta un 90%.
  2. Recuperación de energía.

Las desventajas son:

  1. Si quemas la basura sin separarla, pueden producirse productos altamente tóxicos.
  2. Los productos de lacombustión de cenizas que contienen metales pesados deben recibir un tratamiento especial.

Is it sustainable? Yes, because waste is produced continously and is free. Sí, porque los residuos e producen contuamente y es gratis.
