Verfahren zur Herstellung eines aus kompostierbaren bzw, verrottbaren Materialien gebildeten Gegenstandes sowie hieraus gebildeter GegenstandProcess for the production of an object formed from compostable or rotten materials and object formed therefrom

BESCHREIBUNGDESCRIPTION

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines aus kömpostierbaren bzw. verrottbaren Materialien gebildeten Gegenstandes, sowie einen hieraus gebildeten Gegenstand.The present invention relates to a method for producing an article formed from combable or rotten materials, and to an article formed therefrom.

Es wurden bereits Verfahren entwickelt, Gegenstände aus verrottbaren Materialien herzustellen. Diese Verfahren erzeugen jedoch Gegenstände, die nicht feuchtigkeits- und lüssigkeitsfest sind. Dies bedeuted, daß sie insbesondere nicht geeignet sind Flüssigkeiten oder mit Feuchtigkeit versehene Gegenstände aufzunehmen, da die Gefahr besteht, daß diese sich dabei zesetzen.Processes have already been developed for producing articles from decomposable materials. However, these methods produce objects that are not moisture and liquid resistant. This means that they are particularly unsuitable for absorbing liquids or objects provided with moisture, since there is a risk that they will decompose.

Somit ergibt sich der wesentliche Nachteil, daß diese Gegenstände nicht geeignet sind als Verpackungen und/oder Geschirr, insbesondere Einweggeschirr verwendet zu werden. Somit können sie insbesondere nicht für Getränke, Flüssigkeiten, Soßen und dergleichen eingesetzt werden. Schließlich enthält zumindest jedes zubereitetes Nahrungsmittel in großem Maße Flüssigkeit oder zumindest Feuchtigkeit.This results in the essential disadvantage that these objects are not suitable for use as packaging and / or tableware, in particular disposable tableware. In particular, they cannot be used for drinks, liquids, sauces and the like. Finally, at least every prepared food contains a large amount of liquid or at least moisture.

Weiterhin wurde vielfach nicht verrottbares Einweggeschirr insbesondere in Fast-food Geschäften verwendet, was zu erheblichen Umweltbelastungen führt. Unter dem Zwang der Vermeidung eines derartigen stetigen Anwachsens des Mülls wurde wieder zurückgegriffen auf wiederverwendbare Artikel, wie beispielsweise Porzellangeschirr und Metallbesteck. Dies erfordert jedoch wiederum einen erhebliche Reinigungsaufwand, wobei bei dieser Reinigung äußerst scharfe Reinigungsmittel eingesetzt werden, so daß dadurch das dabei sich ergebende Abwasser stark verschmutzt wird. Dies macht wiederum hohe Aufwendungen zur Klärung des Abwassers notwendi .Furthermore, non-rotten single-use tableware has been used in many cases, particularly in fast food shops, which leads to considerable environmental pollution. Under the constraint of To avoid such a steady growth of the garbage, reusable items such as porcelain dishes and metal cutlery were used again. However, this in turn requires a considerable cleaning effort, with extremely sharp cleaning agents being used in this cleaning, so that the resulting wastewater is thereby heavily contaminated. This in turn makes high expenses for the treatment of the waste water necessary.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zur Herstellung eines kompostierbaren bzw. verrottbaren Gegenstandes zu schaffen» mit dem es möglich ist auch feuchte und/ oder flüssige Materialien aufzunehmen. Darüberhinaus soll die vorliegende Erfindung einen Gegenstand schaffen, der als Verpackungsmateriel bzw. Einweggeschirr dienen kann.The present invention is therefore based on the object of creating a method for producing a compostable or decomposable article » with which it is also possible to take up moist and / or liquid materials. In addition, the present invention is intended to provide an object which can serve as packaging material or disposable tableware.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelös .This object is achieved by the features of claim 1.

Mit Hilfe des Zusatzes von Wasserglas zu dem kompostierbaren bzw. verrottbaren Material ist es möglich einen feuchtigkeistwiderstandsfähigen Gegenstand zu schaffen, der seine Kompostierbarkeit nach Gebrauch aufrechterhält und für seinen Gebrauch gleichzeitig die notwendigen Eigenschaften, insbesondere Lebensmittelverträglichkeit sicherstellt.With the addition of water glass to the compostable or rotten material, it is possible to create a moisture-resistant object that maintains its compostability after use and at the same time ensures the necessary properties, in particular food compatibility, for its use.

Insbesondere ergibt sich eine vorteilhafte Herstellung durch Beimischung des Wasserglases zu den den Gegenstand bildenden Materialien.In particular, there is an advantageous production by admixing the water glass with the materials forming the object.

Weiterhin ist besonders vorteilhaft die Ausbildung mit oder ohne Beimischung durch Beschichten des Gegenstandes mit Wasserglas. Dies kann durch Besprühen, Bestreichen und/oder Eintauchen des Gegenstandes in Wasserglas erfolgen. Als Wasserglas kann ein wenigstens ein Wasserglasderivat, Natronwasserglas und/oder Kaliwasserglas verwendet werden.Furthermore, training with or without admixture by coating the object with water glass is particularly advantageous. This can be done by spraying, brushing and / or immersing the object in water glass. An at least one water glass derivative, sodium water glass and / or potassium water glass can be used as the water glass.

Besonders vorteilhaft ergibt sich, daß als kompostierbares bzw. verrottbares Material ein nachwachsender Rohstoff verwendet wird.It is particularly advantageous that a renewable raw material is used as the compostable or rotten material.

Dies hat den großen Vorteil, daß das Material als Rohstoff der Biomasse zugeführt werden kann und somit in den natürlichen Naturkreislauf rücküberführbar ist.This has the great advantage that the material can be added to the biomass as a raw material and can thus be returned to the natural cycle.

Hierbei ist das verwendete Material vorteilhafterweise aus Stärke und/oder aus pflanzlichen Fasern und/oder aus wenigstens einem Getreideprodukt gebildet.Here, the material used is advantageously formed from starch and / or from vegetable fibers and / or from at least one cereal product.

Aufgrund der erfindungsgemäßen Ausgestaltung eignet sich der erfindungsgemäße Gegenstand besonders als Verpackungsmaterial und/oder Einweggeschirr.Because of the configuration according to the invention, the object according to the invention is particularly suitable as packaging material and / or disposable tableware.

Darüberhinaus ist der erfindungsgemäße Gegenstand auch geeignet an Tiere verfüttert zu werden. Dadurch wird er auch über diese "Entsorgung" dem natürlichen Kreislauf wieder zurückgeführt.In addition, the object according to the invention is also suitable for being fed to animals. As a result, it is returned to the natural cycle via this "disposal".

Zusammenfassend ergibt sich somit, daß mit dem erfindungsgemäßen Verfahren ein Gegenstand geschaffen wird, der die Anforderungen an Recyclingfähigkeit bzw. Verrottbarkeit voll erfüllt unter Schaffung eines für die massenhafte Verwendung geeigneten Gegenstandes. In summary, it follows that an object is created with the method according to the invention that fully meets the requirements for recyclability or rotability while creating an object suitable for mass use.
