So far we have only been talking about bioethanol and biodiesel , but there are not only liquid biofuels. Wood and charcoal are the oldest biofuels in existence, although they are not the only solid biofuels. In Sweden, the sawdust produced in their extraordinary wood industry is compacted and formed into pellets. They are an excellent fuel for their large, efficient boilers that heat entire districts.
The organic waste produced in these cities is also a source of biofuels. It is transported through an elaborate system of pipelines to bioreactors where it is broken down into methane , a gaseous biofuel that can be used both in homes and to power vehicles.
The wood industry is also a source of liquid biofuels. Black liquor is a byproduct of the process of converting wood into paper. This black liquor can be treated to turn it into methanol , a compound that cayman islands phone data can be used as a fuel. All of these options would fall under what is known as second-generation biofuels .
There are several types of second-generation biofuels. Those obtained from non-edible crops , preferably grown on land not suitable for edible crops. And, as in Sweden, those produced by good management by administrations, air pollution technicians and waste policies in general.
In addition, to be considered second generation they must meet a series of requirements:
They must be able to be produced with low CO emissions.2.
It must be synthesized with a responsible use of soil and water.
And its cultivation must respect biodiversity and human rights.
