Carbon Neutral Fertilizer MAde Possible by Belgian Scientists
Making fertilizer ('artificial manure' is the literal translation of the Dutch word) is one of the most polluting processes on earth. Belgian scientists have found a way to produce it locally on a small scale using nothing but the energy coming from a number of solar panels and the air around them.
They use techniques know from diesel engines to produce the ammonia and hydrogen needed for fertilizer. It is estimated that 2% of the worldwide CO2 emmissions come from the production of ammonia.
Because the system is small farmers can produce their own fertilizer eliminating the need for polluting transportation. Because of this the system can also be applied in remote areas where the farmers normally don't have access to a regular supply of fertilizer.
