Dispose of used oil
Often the waste product and the rest of frying, the exhausted oil is generally disposed of because it contains harmful substances that are highly and irreparably toxic for the environment, for humans and for the economy if they are not treated properly beforehand.
Italy has a happy record in disposal, while England (do you remember the project "The Dirty Beaches"?), Which has begun to regenerate exhausted oil recently, is the bottom of Europe. This is why it is more than important, we would say fundamental, to know how to properly dispose of and recycle used oil .
How often do you use oil for frying?
It is usually recommended to use the oil to fry only once. This is because, as seen, vegetable oils generate a high quantity of toxic substances, as in the case of sunflower oil, for example, which generates a very high amount of aldehydes .
Sometimes, when frying for a small amount of food, the food is immersed in dry and well-cleaned boiling oil, without being added to other ingredients - for example spices and various flavorings - you can try using the oil a second time, but at most, no more.
However, it should be well filtered with a dense mesh strainer and kept for a short time in a glass jar or aseptic and well sterilized airtight container, taking care to fry the same kind of food to avoid alterations in flavor.
How to recycle frying oil
Superfluous it is perhaps to remember that the exhausted frying oil is not a biodegradable or organic product, but a food that dispersed in the water forms a thick patina and very harmful for the environment, so much to make even the ground water not potable and spoiling filters and purifiers.
Once the oil has been collected in the special convenient container that can be requested at your town of residence, the oil is brought to the special bins for separate collection, recycling or ecological islands that host them, in fact each municipality has at least one. The alternative is to bring the used oil to supermarkets or petrol stations that take care of collecting and collecting it for free.
What is done with recycled waste oil
Once in the disposal process, the used oil is duly treated, cleaned and regenerated so as to be able to re-enter the vital chain and be reintroduced into the market in other product forms: it is vegetable lubricants for machinery, biodiesel, surfactants, fuels and for energy recovery or glycerine by saponification.
The Conou is the "National Consortium for the management, collection and treatment of used mineral oils", an excellent point of reference for any further clarification or clarification.
In this case, Italy has an excellent record, it is the European leader (Adnkronos) in the collection of used lubricated oils; The English percentage is still too low ; Inghiltarra is still launching awareness campaigns on the subject, aimed at increasing and encouraging the collection of waste oils, both from private individuals and from restaurants or other activities.
