Description

Die Erfindung betrifft ein Verfahren zum Recycling von Plastab­ fällen, vorzugsweise von Mischplastabfällen, zu deren Wiederver­ wendung bei Gebrauchsgütern, als Energiebaustein bei der Energie­ herstellung durch Verbrennung und Herstellung einer Stofform, die einen biologischen Abbau beispielsweise durch Bakterien erleichtert.The invention relates to a method for recycling Plastab cases, preferably mixed plastic waste, for their re-use Use in consumer goods, as an energy component in energy manufacture by combustion and manufacture of a fabric form, the Biodegradation, for example, facilitated by bacteria.

Es sind Verfahren bekannt, die eine Sortenreinheit der Plastabfälle bedingen, die jedoch in der Praxis kaum vorkommt und somit einen hohen Kostenaufwand beim Sortieren erfordern.Processes are known which ensure the purity of the plastic waste condition, which, however, hardly occurs in practice and therefore one require high costs for sorting.

Der Erfindung liegt die Aufgabe zugrunde, mit Hilfe von minimalem Energieaufwand ein kompaktes Produkt mit ca. dem hundertsten Teil des vorher benötigten Rauminhaltes wiederverwendbar herzustellen.The invention has for its object with the help of minimal Energy expenditure is a compact product with approximately one hundredth part to make the previously required volume reusable.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Mischplaste mit kohlenwasserstoffhaltigen Stoffen, vorzugsweise Altöl, in einem zweckmäßigen Verhältnis (vorzugsweise im Verhältnis 1 Teil Altöl: 2 Teile Mischplaste) versetzt und bei ca. 200°C verschmolzen wird.According to the invention the object is achieved in that the mixed plastics with hydrocarbonaceous substances, preferably waste oil, in one appropriate ratio (preferably in a ratio of 1 part waste oil: 2 parts of mixed plastic) and melted at approx. 200 ° C becomes.

Die Schmelze ist gießfähig und erlaubt die Herstellung von Gebrauchs­ gütern, beispielsweise Gartenteichschalen, sowie von Blöcken zur Weiterverarbeitung.The melt is pourable and allows the production of use goods, for example garden pond shells, as well as blocks for Further processing.
