It is surprising to know that a food that has enriched our dishes can end up being a tremendously polluting waste if we do not collect and recycle it well. In this section we do not want to overwhelm you with a lot of data, there are simply two DATA that are very very important.
First we have to know that it begins by affecting the plumbing of our homes and those of our towns and cities, to end in the best of cases in the EDARs, which are like large factories where they try to purify all the wastewater.
There are NOT many reliable studies of what this cost represents, in our opinion there is a serious study, it is from the Bilbao Bizkaia Water Consortium, and they quantify this cost at € 1.6 inhabitant / YEAR, now you calculate this cost only in the Spanish state, well, it will come out about € 90 million each year, that is a lot of money that goes down the drains of our houses, money that could be transformed into jobs to collect that oil and later value it.
That same study forementioned before says textually:
Eliminate and treat 1 liter of used oil that you throw down the toilet costs € 1.6 inhabitant / Year.
