SUMMARY:
Poultry manure disposal is a relevant issue in countries of South East Asia due to the constantly increasing demand for chicken products. Since poultry manure is commonly applied in agriculture for its fertiliser value, there is also a market opportunity associated with it. The price for manure varies depending on the market demand, which leads to transportation of untreated manure over long distances. The risk of this procedure is obvious, as diseases can be spread to a wider area.
A simple treatment before trading the manure would result in several advantages, including hygienisation, volume reduction and easier handling. The EU project CHIMATRA “Chicken Manure Treatment and Application” is currently looking at low tech options for the treatment of chicken manure. One of the recommended methods is a composting system which was implemented as a demonstration plant for training purposes in Malaysia. The major goal of this pilot plant was to demonstrate that a simple composting system could help create a valuable fertilizer from chicken manure. The system consisted of a box composter with a passive chimney aeration and online temperature measurement. The box system was only being used for demonstration purposes; on a larger scale the system can be constructed as a windrow system. Experiments were carried out both in Germany and in Malaysia. During the trials, different constellations of chimneys were evaluated, but the focus of the experiments was on the temperature devolution and evaluation of the hygienisation effectiveness. To compost chicken manure from layers, structural material was added in the form of oat paddy (during experiments in Germany) as a substitute for rice paddy in Asian countries. Furthermore, different types of chicken manure were evaluated. The paper will discuss the results of the composting experiments and further possible application options in South East Asia. Also included is a short summary of a training course with chicken farmers in Malaysia that was undertaken in March 2006 on the pilot plant site. The major goal of the course was to teach interested farmers the use of simple technologies for the treatment of poultry manure.

Europäische Rechtsvorgaben und Auswirkungen auf die Bioabfallwirtschaft in Deutschland

Bioabfälle machen 34 % der Siedlungsabfälle aus und bilden damit die größte Abfallfraktion im Siedlungsabfall in der EU. Rund 40 Millionen Tonnen Bioabfälle werden jährlich in der EU getrennt gesammelt und in ca. 4.500 Kompostierungs- und Vergärungsanlagen behandelt.

Auch mittel- bis langfristig steht zu erwarten, dass die Kaskade aus anaerober und aerober Behandlung Standard für die Biogutbehandlung sein wird.
Die Mischung macht‘s - Der Gärrestmischer in der Praxis

Zur Nachbehandlung von Gärrest aus Bio- und Restabfall entwickelte Eggersmann den Gärrestmischer, der aus Gärresten und Zuschlagstoffen homogene, gut belüftbare Mischungen erzeugt. Damit wird den besonderen Anforderungen der Gärreste mit hohem Wassergehalt begegnet und eine effiziente Kompostierung ermöglicht.
