摘要:
The present invention concerns an anaerobic digestion of animal manures, energy crops and similar organic substrates. The process is capable of refining nutrients comprised in the digested biomass to fertilizers of commercial quality. The invention also provides a method for processing animal carcasses or fractions thereof including meat and bone meal etc., with the objective of providing an alternative means for processing the organic waste material of animal origin while at the same time facilitating the production of fertilizers. The risk of spreading BSE prions or any other prions to animals or humans is thus substantially reduced if not eliminated. The bio-gas and slurry separation system according to the present invention is preferably integrated with the operations of animal husbandries into a total concept in which the internal and external performances of animal husbandries are optimised. The internal performances concern quality aspects related to the management of the animal houses and include industrial hygiene, animal welfare, gaseous and dust emissions and food safety. The external performances concern mainly energy production and emissions to the environment of nutrients and greenhouse gasses and the sale of high quality food product.

A method and an apparatus is provided for aeration of organic material, wherein the organic material undergoes an aerobic composting process, such that air is caused to evenly penetrate the organic material. The organic material is first sealed in a vessel. Air is then delivered to the contents of the vessel such that an air pressure of from about 1 to about 1000 kPa above atmospheric pressure is maintained in the vessel. A pressure differential initially forms and is then allowed to equilibrate over a period of time, in which time air flows from areas of high pressure to areas of low pressure in the organic material thus ensuring that aeration is evenly distributed throughout the organic material.

Vorgeschlagen ist ein Verfahren zur Behandlung eines phosphorhaltigen Materials, insbesondere von Klärschlamm oder Tiermehl, umfassend die folgenden Schritte: - Bereitstellen eines phosphorhaltigen Materials mit einem ersten Wassergehalt; - Vermischen des phosphorhaltigen Materials mit zumindest einer kaliumhaltigen Substanz, um ein Gemisch zu erhalten; - Reduzieren des Wassergehalts des Gemisches auf einen zweiten Wassergehalt; - Thermisches Umsetzen des Gemisches, insbesondere unter reduzierenden Bedingungen, um ein Produkt zu erhalten. Ferner ist ein Düngemittel oder Düngemittelzusatz sowie die Verwendung eines Produktes, jeweils herstellbar mit einem derartigen Verfahren, vorgeschlagen.

Dispositif modulable de collecte, transport, entreposage et trempage lors d'un processus d'hydrolyse alcaline pour des cadavres d'animaux familiers. L'invention concerne un dispositif modulable (1) de collecte, transport, entreposage et trempage lors d'hydrolyse alcaline de cadavres d'animaux familiers utilisable pour la prise en charge de façon individuelle, séparée et identifiable, collective des cadavres. Le dispositif (1) est un récipient modulable comportant une paroi pleine à hauteur réglable (9), une paroi supérieure à hauteur variable (6), plusieurs ouvertures dans des plans différents (10a, 10b, 10c), un système de guidage (11) pouvant le solidariser à une structure externe, des pieds (12) et poignées (13) permettant sa manutention horizontale comme un brancard, au moins deux roues éventuellement amovibles (16) permettant son déplacement comme un diable de manutention et des parois internes amovibles réglables (17) permettant de le fractionner en espaces séparés et identifiables. Le dispositif (1), selon l'invention, est particulièrement destiné au domaine du traitement des cadavres d'animaux familiers.
摘要:
There is provided a carcass disposer sterilizing a carcass by supplying high-pressure steam into a steam drum seated on one side of an upper portion of a base frame. The carcass disposer includes a cover installed upright to horizontally move along transfer rails installed on the other side of the base frame, and selectively opening and closing the steam drum; and a carcass loading table integrally connected to an inner surface of the cover, and being automatically taken in or out along transfer rails inside the steam drum as the cover is selectively opened and closed.
