Descrizione della domanda di Brevetto per Invenzione Industriale dal titolo: Description of the patent application for Industrial Invention entitled:
"Procedimento per ottenere stoviglie e contenitori monouso in plastica biodegradabili e stoviglie e contenitori così ottenuti". "Process for obtaining disposable dishes and containers in biodegradable plastic and dishes and containers thus obtained".
DESCRIZIONE PROVVISORIA PROVISIONAL DESCRIPTION
L'invenzione, di cui alla presente domanda, ha per oggetto un procedimento per ottenere stoviglie e contenitori monouso in plastica biodegradabili e stoviglie e contenitori così ottenuti. The invention of the present application relates to a process for obtaining disposable dishes and containers in biodegradable plastic and dishes and containers thus obtained.
Trova sempre più diffusione, per la consumazione di prodotti alimentari, l'utilizzo di stoviglie monouso realizzate in materiale plastico. The use of disposable tableware made of plastic material is increasingly widespread for the consumption of food products.
Detta diffusione ha causato gravi conseguenze in tema di smaltimento dei rifiuti, è infatti noto che il tempo di decomposizione delle materie plastiche sintetiche derivanti dal petrolio è di circa 1.000,00 anni. This diffusion has caused serious consequences in terms of waste disposal, it is in fact known that the decomposition time of synthetic plastic materials deriving from petroleum is about 1,000.00 years.
Sono noti impieghi di materiali alternativi al fine di rendere più veloce il processo di biodegrazione o decomposizione delle materie plastiche. In particolare, la decomposizione consistente nella mineralizzazione delle strutture organiche da parte di microrganismi che trasformano le c.d. bioplastiche in biossido di carbonio, metano, acqua e biomassa. Uses of alternative materials are known in order to speed up the biodegration or decomposition process of plastic materials. In particular, the decomposition consisting in the mineralization of organic structures by microorganisms that transform the so-called bioplastics in carbon dioxide, methane, water and biomass.
L'impiego di detti materiali presenta, comunque, una serie di inconvenienti, primo fra tutti la riduzione della disponibilità di derrate alimentari, se prodotte a partire da prodotti agricoli come il Zea mays. Le plastiche bio attualmente sul mercato sono: Mater-Bi, Pia Ingeo, Biolice, Biotec, Biograde, Cereplast Compostables, composte principalmente da farina o amido di mais, grano o altri cereali. The use of said materials has, however, a series of drawbacks, first of all the reduction in the availability of foodstuffs, if produced starting from agricultural products such as Zea mays. The bio plastics currently on the market are: Mater-Bi, Pia Ingeo, Biolice, Biotec, Biograde, Cereplast Compostables, mainly composed of flour or starch of corn, wheat or other cereals.
Scopo della presente invenzione è risolvere i problemi su descritti fornendo stoviglie e contenitori in genere, monouso. The object of the present invention is to solve the problems described above by providing disposable dishes and containers in general.
Altri scopi e vantaggi del procedimento per ottenere stoviglie e contenitori in generale, monouso biodegradabili, di cui alla presente invenzione, risulteranno evidenti dalla descrizione che segue. Other objects and advantages of the process for obtaining biodegradable disposable crockery and containers in general, of the present invention, will become evident from the following description.
Così come rivendicato, le stoviglie monouso, di cui alla presente invenzione, sono prodotte in plastica tradizionale (polistirolo cristallo e polistirolo antiurto - o polipropilene o Pet - , masterbatch coloranti e masterbatch stabilizzanti) con aggiunta di additivi oxobiodegradabili e/o idrodegradabili. As claimed, the disposable tableware, according to the present invention, are produced in traditional plastic (crystal polystyrene and shockproof polystyrene - or polypropylene or Pet -, coloring masterbatches and stabilizing masterbatches) with the addition of oxobiodegradable and / or water degradable additives.
Il processo di degradazione è comune a tutte le plastiche, ma nel lungo periodo le stoviglie ed i contenitori realizzati con il presente procedimento, comprimono tale naturale processo, facendo sì che invece di centinaia di anni, la degradazione sia della durata di un periodo compreso tra minimo 36 mesi a massimo 9 anni. The degradation process is common to all plastics, but in the long term the dishes and containers made with this process compress this natural process, causing instead of hundreds of years the degradation to last for a period between minimum 36 months to maximum 9 years.
Il processo produttivo si compone delle seguenti fasi: The production process consists of the following phases:
composizione del mix tra granuli di polistirolo (o Pet o polipropilene) e additivo oxodegradabile/idrodegradabile; composition of the mix between polystyrene granules (or Pet or polypropylene) and oxodegradable / hydrodegradable additive;
estrusione del granulo così ottenuto in foglia; extrusion of the granule thus obtained into a leaf;
termoformatura della foglia estrusa mediante l'utilizzo di stampi; thermoforming of the extruded sheet through the use of molds;
eventuale bordatura/rifinitura del prodotto finito; possible edging / finishing of the finished product;
confezionamento del prodotto. product packaging.
Il processo di degradazione avviene grazie all'aggressione di microrganismi che disgregano le catene polimeriche e attraverso ossigeno e/o acqua le riducono in entità frammentate. Le entità frammentate avranno un peso molecolare molto ridotto rispetto ai polimeri tradizionali derivati dalla petrolchimica. The degradation process takes place thanks to the aggression of microorganisms that break up the polymer chains and through oxygen and / or water reduce them into fragmented entities. The fragmented entities will have a very low molecular weight compared to traditional polymers derived from petrochemicals.
Si noti che in natura non esistono le catene polimeriche delle plastiche, poiché esistono invece i monomeri che, grazie all'azione deN'uomo, vengono legati in catene, caratteristica che rende la struttura difficile da degradare; la frammentazione facilita l'aggressione da parte dei funghi e dei batteri. Il residui che si produrranno dalla "digestione" dei batteri saranno humus, C02 e metano. It should be noted that in nature the polymeric chains of plastics do not exist, since there are monomers which, thanks to the action of man, are linked in chains, a characteristic that makes the structure difficult to degrade; fragmentation facilitates aggression by fungi and bacteria. The residues that will be produced by the "digestion" of the bacteria will be humus, C02 and methane.
