Abstract

Foamed starch in the form of particles can be used as an additive in composting or to improve soil. Pref. the starch particles are 2-10 mm. When used in the composting of clear or watery muds, esp. contamined mud, the starch particles are pref. mixed with the mud which has been substantially dried. Alternatively the starch particles are mixed with soil or the crude compost in the cases of improving soil or composting organic waste. USE/ADVANTAGE - The starch particles are porous and have a large surface area to and are thus able to loosen and aerate the compost or soil and thus save the need to turn the soil or rotting compost repeatedly in order to promote microbial growth and the biological degredation of the organic components. The starch particles can be used to compost organic waste, be it of domestic or industrial origin, but are esp. useful in the composting of clear and watery mud, such as habour mud, esp. contaminated mud, and to improve the soil in fields or contaminated soil. The starch is able to a large extent to remove organic poisons.

Description

Die Erfindung bezieht sich auf die Verwendung verschäum­ ter Stärke.The invention relates to the use foaming ter strength.

Es ist bekannt, verschäumte Stärke als Verpackungsmate­ rial, insbesondere für Nahrungsmittel, zu verwenden, da sie leicht biologisch abbaubar ist und sich in großen Mengen aus pflanzlichen Rohstoffen gewinnen läßt.It is known to use foamed starch as a packaging material rial, especially for food, since it is easily biodegradable and large Lots can be obtained from vegetable raw materials.

Erfindungsgemäß wird vorgeschlagen, derartige verschäumte Stärke in Form von Teilchen als Zusatz bei der Kompostie­ rung oder zur Bodenverbesserung zu verwenden.According to the invention, it is proposed to foam such Starch in the form of particles as an additive in composting or to improve the soil.

Hierbei tragen die Stärketeilchen, vorzugsweise in einer Größe von zwei bis zehn Millimeter, aufgrund ihrer Poro­ sität und dementsprechend großen Oberfläche zur Auflocke­ rung und Belüftung des Kompostes bzw. des Bodens bei und ersparen ein mehrmaliges Umsetzen des angerotteten Kom­ postes bzw. des Bodens, um das mikrobielle Wachstum und damit den biologischen Abbau der organischen Bestandteile des Rohkompostes bzw. Bodens durch Mikroorganismen zu för­ dern. Here, the starch particles carry, preferably in one Size of two to ten millimeters, due to their poro and accordingly large surface area for loosening ventilation and aeration of the compost or soil at and save the repackaged comm postes or the soil to the microbial growth and thus the biodegradation of the organic components the raw compost or soil by microorganisms other.  

Besonders geeignet ist die Verwendung dieser Stärketeil­ chen zur Kompostierung von Klär- und Gewässerschlamm, wie Hafenschlamm, insbesondere kontaminiertem Schlamm, aber auch zur Verbesserung von Ackerböden oder kontaminierten Böden, bei der die Stärketeilchen mit dem weitgehend getrockneten Schlamm bzw. der Erde vermischt werden. Hier­ bei kann der Schlamm oder die Erde in einem solchen Men­ genverhältnis, je nach Belastung des Schlamms oder des Bodens durch organische Gifte, bis hin zu Dioxin, mit den Stärketeilchen, gegebenenfalls nach dem Abbau der organi­ schen Gifte erneut, vermischt werden, so daß der kompo­ stierte Schlamm schließlich als Düngemittel verwendet und der zuvor kontaminierte Boden schließlich als entgiftet betrachtet werden kann.The use of this starch part is particularly suitable Chen for composting sewage and water sludge, such as Port sludge, especially contaminated sludge, however also to improve arable land or contaminated Soils in which the starch particles largely with the dried sludge or soil. Here at the mud or the earth in such a menu ratio, depending on the load of the sludge or the Soil through organic poisons, down to dioxin, with the Starch particles, if necessary after the decomposition of the organi poisons again, are mixed so that the compo bulled mud finally used as fertilizer and the previously contaminated soil is finally detoxified can be viewed.

Bei nicht zu hoch durch organische Gifte belasteten Schlämmen oder Böden kann ein Zusatz von Stärketeilchen in einem Mengenverhältnis von 10 bis 25 Gewichtsprozent, bezogen auf das Gemisch, ausreichend sein. Mit einem hohen Anteil organischer Gifte belastete Schlämme können nach herkömmlichen Sortierverfahren, z. B. nach weitgehen­ der Entwässerung in halb durchlässigen Säcken, sogenann­ ten Schrumpfsäcken, in weniger und sehr hoch belastete Anteile aufgeteilt werden, wobei dann die weniger belaste­ ten unter Zusatz von Stärketeilchen kompostiert und zu­ mindest bis auf einen ungefährlichen Anteil organischer Gifte entgiftet, dagegen die hochbelasteten verbrannt wer­ den.In case of organic toxins not too high Sludge or soils can add starch particles in a ratio of 10 to 25 percent by weight, based on the mixture, be sufficient. With a sludge contaminated with high levels of organic toxins according to conventional sorting methods, e.g. B. go after drainage in semi-permeable bags, so-called th shrink bags, in less and very heavily loaded Shares are divided, then the less burden composted and added with the addition of starch particles at least up to a harmless part of organic Toxins detoxified, whereas those who are heavily loaded are burned the.

Zur Verbesserung oder Kultivierung unbelasteter Böden kann dagegen eine Beimischung in einem Verhältnis von 5 bis 9 Gewichtsprozent Stärketeilchen, bezogen auf das Gemisch, ausreichend sein.To improve or cultivate unpolluted soils on the other hand, an admixture in a ratio of 5 to 9 weight percent starch particles, based on the Mixture, be sufficient.

Desgleichen können die Stärketeilchen zur Kompostierung organischer Abfälle, seien es Haus- oder Industrieabfälle, verwendet werden, wobei auch hier die Stärketeilchen mit dem Rohkompost vermischt werden, z. B. in einem Men­ genverhältnis von 10 bis 30 Gewichtsprozent Stärketeil­ chen, bezogen auf das Gemisch.Likewise, the starch particles can be used for composting organic waste, be it domestic or industrial waste,  are used, the starch particles also here are mixed with the raw compost, e.g. B. in a menu ratio of 10 to 30 weight percent starch chen, based on the mixture.
