Abstract

A recycling process for composite packaging involves fermentation with the aid of a substance such as clarification sludge, using a bio-gas unit operated with or without heating. Pref., after fermentation, polyethylene floats on the surface of the fermenting substance and any metal, contained in the packaging, sinks.

Description

Der Stand der heutigen Technik hat den Nachteil, daß beim Recyclen sehr viel Trinkwasser und Energie (für die Heizung) benötigt wird.The state of the art today has the disadvantage that when recycling a lot Drinking water and energy (for heating) is needed.

Die Aufgabe der Erfindung besteht darin, daß die Verbundverpackungen kostengünstig und umweltschonend recycelt werden.The object of the invention is that the composite packaging be recycled cost-effectively and environmentally friendly.

Die Aufgabe wird durch die Vergärung mit einer gärfördernden Substanz, wie z. B. Klärschlamm, gelöst.The task is achieved by fermentation with a fermenting substance, such as z. As sewage sludge, solved.

Die Erfindung hat den Vorteil, daß die Verpackungen ohne Chemikalien, ohne hohen Trinkwasserverbrauch, sowie ohne hohe Heizkosten recycelt werden können. The invention has the advantage that the packaging without chemicals, without high drinking water consumption, as well as being recycled without high heating costs can.  

Tetrapacks sind Verbundverpackungen, die sehr häufig gebraucht werden, aber es gibt nur wenige Verwertungsanlagen in Deutschland. Trotz allem werden diese Verpackungen im Gelben Sack gesammelt. Die jetzige Verwertung ist kostspielig und aufwendig. Ein großer Bestandteil dieser Methode ist das Trinkwasser.Tetrapacks are composite packages that are used very often, but it There are only a few recycling plants in Germany. Despite everything, these are Packaging collected in yellow bag. The current recycling is costly and elaborate. A big part of this method is drinking water.

Jetzige VerwertungCurrent recovery Meine VersionMy version Die Tetrapacks werden gesammeltThe tetra packs are collected EbensoAs well Sie werden in Gruppen aufgeteiltThey are divided into groups -- Säuberung mit WasserPurification with water -- Kochen in WasserCooking in water Vergären mit KlärschlammFermentation with sewage sludge Polyäthylen und Aluminium werden von dem Gemisch abgelöstPolyethylene and aluminum are removed from the mixture EbensoAs well Alu und PE wird gesäubertAlu and PE are cleaned EbensoAs well

Bei der jetzigen Methode entsteht ein sehr hoher Trinkwasserverlust. Auch die Heizkosten sind nicht unbedeutend, ich machte einen Versuch, indem ich die Biogasanlage ohne Heizung laufen ließ. Das Ergebnis war fast gleich, zu dem des Versuchs mit Heizung, nur die Gasproduktion war nicht so gut. Also könnte man sich bei einer großen Anlage mit guter Isolierung eine Heizung und damit auch den größten Kostenpunkt sparen. Die Vergärung mit Klärschlamm ist sehr einfach, und auf den Mülldeponien wäre wieder etwas Freiraum. Bei der Sammlung könnte es direkt einen Sack für Verbundverpackungen geben, denn dadurch entfällt die problematische Trennung zwischen Verbundverpackungen und Restmüll. Der Platz für eine Vergärungsanlage entspricht ca. einem Faulturm in den Kläranlagen. Durch die Trinkwasser- und Stromersparnis ist meine Anlage preisgünstiger. Als Reaktor könnte man einen Faulturm nehmen, der aber luftdicht abgeschlossen sein müßte. Die Kosten würden ungefähr dasselbe betragen. Zum Einfüllen der ungewaschenen Verbunde eignet sich ein Förderband, der anfallende Klärschlamm wird genauso behandelt wie im Klärwerk.The current method results in a very high drinking water loss. Also the Heating costs are not insignificant, I made an attempt by putting the Biogas plant ran without heating. The result was almost equal to that of the Experiment with heating, only the gas production was not so good. So you could In a large system with good insulation, a heater and thus the save the biggest cost. The fermentation with sewage sludge is very simple, and on the landfills would be some space again. The collection could be directly give a bag for composite packaging, because this eliminates the problematic separation between composite packaging and residual waste. The space for a fermentation plant corresponds approximately to a digester in the sewage treatment plants. By the drinking water and electricity savings my system is cheaper. As a reactor you could take a digester, but the airtight would have to be completed. The cost would be about the same. To fill the unwashed Composites is a conveyor belt, the accumulating sewage sludge is the same treated as in the sewage treatment plant.

Es ist also eine ernstzunehmende Methode zum Recycling der Verbundver­ packungen.It is therefore a serious method for recycling the Verbundver packaging.
