water and oil (fried) many have wondered, after every fry, where you can pour the waste oil? And the oil canning? Butter and margarine that remain in the pots? Finally today this problem has a solution, curbing environmental pollution that we all, unknowingly, we have helped to generate.
When oils and fats, cooking oil come from any productive activity are considered "non-hazardous waste", destined for recovery in accordance with art. 184 paragraph 2, of Legislative Decree 152/2006.
Decree Law No. 152/2006, is the standard reference in the field of waste management. It established the National Consortium for collecting and processing of oils and fats of plant and animal catalysts (cone), which ensures the proper management of such waste, ie: their collection from the creators because of his professional activities, transportation, storage, treatment, and finally, recovery. In fact, oils and fats, animal and vegetable oils, are "recoverable", that if subjected to appropriate treatment processes and regeneration, enable as "secondary raw materials" the production of fat for construction, glycerin and methyl ester, vegetable oil lubricant, soaps, biodiesel, electricity.
Many of us with irresponsible habit, have always poured into sinks, and therefore in sewage, soil or even in your garden, the remaining oil or butter for seasoning, frying, canning, food subt ' oil (eg canned tuna), unaware of the consequences, in terms of environmental pollution generated by this gesture: pollution of underground water courses surface of the water (preventing oxygen and endangering the ' existence of flora and fauna) as well as problems of proper management and operation of wastewater treatment plants of civilians. Discard the oil in the sewage is highly polluting! Remember that the environment is a gift you received from your parents and you are required to give to your children.
USED VEGETABLE OIL FOR FRYING: A THREAT TO THE ENVIRONMENT In Italy are every year, released for consumption (directly as cooking oil or because present in other food) to 1.4 billion pounds (1,400,000 tons) of vegetable oil for an average consumption of about 25 kg per capita per year (source: Ministry of Health). Of this quantity is estimated to be remaining unused amounts to about 20%. We are therefore faced with more than 280 million pounds (280 thousand tons.) of used vegetable oil, about 5 kg each, every year "give back" to the environment, largely as a residue frying, and therefore "rich" of pollutants.
There are several experimental works of Italian and foreign researchers aim to study the dynamics of the reactions and thermal that oxidative and the quality and quantity of more or less toxic substances that are produced during the frying of food.
vegetable oil, in fact, led to the high temperatures needed for frying , changing its structure. A complex series of reactions leading to the formation of numerous oxidation products and a large number of breakdown products of volatile and nonvolatile. The volatile compounds are lost during frying non-volatile oil to accumulate in the latter after a certain number of heating, it must be considered damaged and more has absorbed the pollutants resulting from the charring of the food waste.
The changes above are also discernible effects such as defects in the smell and flavor, darkening of the color, viscosity increase, lowering the smoke point, foaming, etc.. directly related to the state of degradation of the oil.
The result is a substance that has lost virtually all of the original purity and authenticity, and that has become a serious hazard if dispersed in the environment.
oil that enters the ground is deposited with a thin film around the soil particles and thus forming a barrier layer between the particles own, the capillary water and the roots of plants, preventing the intake of nutrients. If the ' oil reaches the mirror of the water table form on the same layer with a thickness of 3-5 cm. that moves with the water downstream, so drinking water wells can reach very far, making them unusable, because a quart of oil mixed with one million gallons of water is enough to alter the taste in a restriction which conflicts with the potability.
oil instead reach any body of surface water can go to form a thin waterproof film that prevents oxygen and undermines the existence of flora and fauna. It 'amazing to think that one kilogram of oil used is sufficient for this film with an area of \u200b\u200b1000 square meters.
Disposal of this huge amount of oily residue will cause problems even where there are proper sanitation, because it can undermine the proper functioning of water treatment plants (negatively influence the biological treatment) and still make it secure economy, in fact in the preliminary phase of treatment requires the creation of special oil separators, based on the principle of flotation to separate the form of material floating oils and fats present in sewage.
Only a correct and controlled disposal of vegetable oil used can therefore ensure the protection of the environment.
A SOURCE OF ENERGY SAVING
Like many other residues also ' used vegetable oil can be, if separately collected from other waste and environmental benefits also a source of energy savings because it is possible after correct processes of regeneration, a re-use industry.
L ' used vegetable oil collected from companies authorized pickers in suitable containers for storage and transport companies to start regeneration.
Here you proceed to the stage of screening to separate the solids, then stored and then treated. Then the continuous regeneration process by bringing the compound at a temperature of about 70 degrees and carried in special "agitators serpentine" or " centrifuge, and separated from other substances, and then cooled. The water thus obtained, in turn, are purified.
Then you add the additives and carbonaceous substances are filtered.
The material obtained is subjected to heat treatment to remove the volatile acids present in small percentages, but responsible for odor of treated products.
The derivative of this process, depending on the degree of purity and transparency achieved, can be reused in various ways, for example, as a base (up to 20-30%) for mineral oil, or started the production of emulsifiers for asphalt and bitumen road.
one kilogram of vegetable oil used are obtained 0.8 kg of regenerated lubricating base: a significant saving when you consider that the alternative to the recycled product would consist of synthetic mineral oil derivante da prodotti petroliferi.
Il 20% di residuo che deriva dalla rigenerazione viene utilizzato in impianti adatti a farne usi industriali come ad esempio la produzione di mastici, distaccanti per casseforme di cemento, inchiostri da stampa e saponi industriali, inoltre attraverso controlli adeguati e sofisticati cicli di rigenerazione, può essere anche riutilizzato nella mangimistica animale.
Negli ultimi anni in Italia quasi l’80% del prodotto rigenerato dall’olio vegetale usato è stato riutilizzato in mangimistica animale fino a maggio di quest’anno quando è scoppiato lo scandalo dei polli alla diossina in Belgio.
DIOXIN SCANDAL IN BELGIUM
In Belgium as early as January-February 1999, some engineers had discovered that the intensive farming of chickens for eggs and chickens were born without a shell, analyzing the chickens had been discovered that they had a very high percentage of dioxin. The Belgian government has kept around until June 1999 when the scandal broke.
According to experts, after investigation, the source of pollution by dioxins in eggs and poultry should be sought in the use of feed supplemented with fat derived from '
oil grill , repeatedly and incorrectly used. The Accused would in particular the system of separate collection of waste frying in Belgium. It is therefore possible that in containers designed to collect edible oils have been thrown mineral oil, a possible source of contamination. Dioxin can not be in any way in
frying oils, nor can it be contained meat and bone meal to make if they are used only fats and vegetable oils and animal bones .. Although the collection is made in Italy with a door to door based on agreements between companies gatherers and producers of vegetable oils, and then you can check the source of the product, the feed Italians have decided not to use meat and bone meal with the addition of vegetable oils
.
In part it arose the question of disposal, recovery and reuse the oil as was the enormous amount used by companies for processing into flour and it was decided to use it for processing into bio-diesel project that was already in experimental stage and now uses most of the oil used.
THE BIO-DIESEL The Bio-diesel , the best known of the fuel alternative to diesel, is extracted from plants and seeds for its non-polluting. It is used both for transport and for heating fuel this plant for its nature helps to reduce atmospheric emissions of pollutants, typical of mineral fuels and / or methane. The vegetable oil exhausted, as well as extracts of plant seeds, is used as a basis for making Bio-diesel
or
ecological fuel, then the product is greatly ennobled passing from waste to fuel ecology.
PROCESSING OIL USED FOR THE BIO-DIESEL arrival of the waste in the factory are made to quality control and routine analysis, then
is done by unifying and elimination of odors and winterizzazione necessary for use as bio-diesel
. This process serves to lower the temperature at which the product is still able to run (ie it is still liquid) and is brought to the pour point of -6 ° C °.
The next process consists in a transesterification with methyl alcohol is then ready for the Bio-diesel made from vegetable fatty acid methyl esters.
After we saw the damage that may result in non-disposal through official channels of '
used vegetable oil and its possible uses in industry, animal feed, and as an energy source, we see what is being done in Italy to try to recover most of that refusal.
IDEA CONSORTIUM
The "National Consortium for collecting and processing vegetable oils and animal fats" was founded in 1991 by an agreement between companies and companies harvesting regenerators used vegetable oil, in order to optimize the collection throughout the country and provide its customers, on the one hand a comprehensive and efficient service, the other, the absolute guarantee of compliance with current legislation.
Since 1991, the Consortium continues to expand as both volume collection, both in number of customers served (mostly workers in the catering sector), and for many other associated companies of the Consortium shared the spirit and objectives.
Today the Consortium has 15 companies and 120 companies regenerative pickers.
entrepreneurs who lead them, the obvious desire to live and advance their businesses, which together employ more than 1000 employees combine a profound ecological awareness and stimulating the conviction to make with their work and with over 5 million oil used crop an active contribution to environmental protection.
SERVICE
The quality of the service is any of the carriers on which the Consortium has based its strategy.
The goal has been from the outset and is increasingly to combine a standard supply and efficiency of a customized service.
Each of the companies serve more than 50,000 members of the Consortium bins provide a suitable container to the collection and storage of used oil to an appropriate size of volumes produced by each customer (if required) the complaint to the land waste, namely
the MUD (single model of environmental statement) . Significantly
valuable, especially at a time like the present where all the regulations on classification, collection and allocation of waste is in constant evolution is also the activity of "advice" that the consortium can offer to their customers, updating them timely information about obligations under new legislation passed or rules introduced and providing them with an excellent service in compliance with the legislation.
A CONSORTIUM TO MANDATORY
Two important elements of consideration:
- the very high power pollutant of a substance such as' used vegetable oil that, by its very nature as a "liquid", is certainly more insidious than other waste, because more easily disposed of improperly,
- read the following estimation :
70 million gallons of used oil products from restaurants ,
5 million gallons disposed of by the member companies ,
5 million gallons disposed of by other companies authorized , then
There are about 60 million liters or not disposed of or if they are not is known for much of route and destination.
The strong suspicion is that in the absence of a monitoring and a systematic, much of this oil can be used illegally on the road to re-use in the food industry.
is insufficient evidence to suggest that the sector needs to be carefully regulated.
The most satisfactory results in recent years by the Consortium Required that deals with the collection of mineral oils exhausted, albeit carefully assessing the differences between the two waste reinforces the belief that the most effective way to go for vegetable oil is similar. And in fact with the Legislative Decree No 22 of 5 February 1997 was Chartered
Mandatory Consortium of vegetable oils that will be responsible for organizing and controlling the collection and disposal of used oil is made, on the whole national territory, in full compliance with applicable laws.
RECYCLING PILOT PROJECT
L '
product used vegetable oil from restaurant operators
(
restaurants, pizzerias
,
canteens , etc..) is not a party, although significant, the total quantity.
The other major source of dispersal of
used vegetable oil, is produced by the oil poured into sewage systems as household waste. Amounts are individually insignificant, but taken together incredibly large: 210 million liters per year, equivalent to about 3.8 kg capita.
collect this oil is also very difficult undertaking, however, that it becomes impossible if you are unable to activate the cooperation of every citizen and local government and for this to happen it is essential that there is information and awareness.
The organization of a collection service from the capillary allowed to recover from even this large amount of oil poured down the sink now.
In concert, each domestic producer, as well as to provide also raising awareness, should strive to give the 'old oil
at
special containers located in the spaces provided by the public and / or businesses.
laudable initiatives have already started in some cities, ecological islands in Macerata, and other places are being launched. The confusion, however, between the types of mineral oil and vegetable oil, for which the waste may be mixed incorrectly, causing a real problem of disposal for the impossibility of re-use, requires that containers be placed in controlled spaces. This, perhaps, together with a certain inertia of local and an investment is not supported by quantitative initially recover from domestic production was one of the limitations encountered so far at the takeoff of a collection plan that involved staff all citizens, which now even if armed with good will, they do not know where or how to give them more or less small but significant amount of waste.
We believe that several initiatives can be viable for the involvement all institutional bodies and individuals.
Regions, to boost recycling of waste vegetable oils
and oppose this massive loss could have its own specific rules.
Municipalities should include in their regulations the manner of collection of service with the definition of areas in which every citizen can possibly give their plastic containers and economic support to be provided for new projects. These areas can be identified in local areas (ecological islands) or private (condominiums, commercial areas, schools, parishes). Important
still proves the work of all who see this initiative as a real contribution to environmental protection by helping to raise awareness, promote and facilitate by all administrations, the establishment of separate collection of waste vegetable oils.
We are still in their infancy, but these proposals, even under the infant's Mandatory National Consortium, is certainly in the right direction is towards the establishment of a challenging project and an investment that are adequate to solve a major problem for the Protection of 'environment.
SOME BRIEF EXPLANATION ON PREVIOUS
= OXIDATION chemical reaction for which a substance or item is combined with oxygen.
CARBONIZATION = process of reduction of organic substances, which tends to keep only the carbon
FLOTATION = exploits the properties of certain solids to be hydrophilic, that is to absorb water compared to others that are hydrophobic, which water does not stick. This is accomplished pulverizing the solid mixture and suspending it in water. Then added a foaming agent and blows into the water. The hydrophilic component, which became heavier, settles on the bottom of the container, while the hydrophobic adheres to bubbles gas and this is dragged to the surface.
DIOXIN = is the chemical with the highest content of toxic, man-made as a byproduct of certain harmful chemical reactions and as a byproduct of any generic form of incineration, in small quantities. Of course you should try to minimize emissions to very low levels, but "Zero Dioxin ', zero = zero, the value expressed by Greenpeace in its report, is unthinkable. If we are serious about zero, you should eliminate all forms of heating with fossil fuels, stop driving on the engine, close all factories, whether they use or do not use chlorine because they generate all the quantities, even if infinitesimal traces of dioxin and other harmful substances that are spread out to air, water and soil. And, finally and most important, you should stop nature because nature itself produces dioxin from burning natural.
There have been incidents in which they were made large amounts of dioxins, and from which we can deduce what are the risks in the short and long term the drug-related. The most famous is the incident at Seveso. Caused by an overheated reactor began to issue in the area surrounding a cloud of chemicals produced by the reaction, including from a few hundred grams to a few pounds of the type of the most toxic dioxin.
