Abstract
Biological utilisation of waste material and/or waste heat from bioreactors e.g. fermenters by supplying these waste products as plant growth factors. Utilises the very large amounts of material particularly CO2 and of heat produced from biological processes and at present entirely wasted. The CO2-containing waste air e.g. from fermenters, is pref. supplied by pipeline and distributions equipment together with waste heat, both to plants grown in open fields and to those in greenhouses. Alternatively, the waste products are utilised for submerged plant growth, e.g. algae cultivation.
Description
Gegenstand der Erfindung ist ein Verfahren zur biologischen Ausnutzung von Abfallstoffen und/oder Abwärme von Bioreaktoren, beispielsweise aus Fermentern.
Es ist bekannt, dass Bioreaktoren - speziell für die Herstellung von Mikroorganismen, welche als Nahrungs- und Futtermittel verwendet werden - einerseits grosse Mengen von Kohlensäure, anderseits entsprechend grosse Mengen von Wärme als Abfall produzieren. Je nachdem, welche Nährsubstrate für die meist aerobe Fermentierung verwendet werden, fallen 3000 bis 10 000 kg Cal pro kg erzeugte Trockensubstanz an und eine entsprechend grosse Menge von Kohlensäure. Die Wärme muss durch entsprechende Kühlung abgeführt werden, und die Kohlensäure verlässt die Reaktoren in der Abluft. Als Beispiel soll erwähnt werden, dass ein Bioreaktor von 200 m3 Nutzinhalt, in welchem Futterhefe hergestellt wird. und welcher im Tag ungefähr 20 000 kg Trockenhefe erzeugt, bei einer Belüftungsrate von 1,5 Volumen Luft pro Minute, täglich 432 000 m3 Abluft ausstösst.
Diese Abluft enthält - je nach Produkt - 2 bis 10 % Kohlensäure-Gas. Es ist dies eine enorme Menge CO2, welches in die Atmosphäre ausgeströmt wird. Auf der anderen Seite müssen durch die erwähnte Kühlung - ebenfalls je nach Produkt - pro Tag ungefähr 60 bis 200 Millionen kg Cal Wärme abgeführt werden.
Die erwähnten Hefen, oder Bakterien und Pilze, werden bekanntlich in immer grösserem Umfang als Nahrungs- und Futtermittel auf obige Weise erzeugt. Da nun vielfach in jenen Ländern. in welchen soche künstliche Eiweissprodukte hergestellt werden müssen, auch die übrigen, pflanzlichen Nahrungs- und Futtermittel fehlen - oder zumindest knapp sind, wäre interessant, eine Symbiose zwischen Bioreaktoren und Grünkulturen zu erreichen.
Aufgabe der Erfindung ist die Ausnutzung von unverwerteten Abfallprodukten von Bioreaktoren für Grünkulturen.
Die Aufgabe wird erfindungsgemäss durch ein Verfahren so gelöst. dass diese Abfallprodukte als Wachstumsfaktoren Grünkulturen zugeführt werden.
Nachstehend wird der Erfindungsgegenstand beispielsweise erläutert.
Während die Eiweisse erzeugenden Mikroorganismen Kohlensäure und Wärme als Abfallprodukte produzieren, brauchen grüne Pflanzen grosse Mengen dieser beiden Abfallprodukte für ihr Wachstum. Neuerdings werden solche Grünkulturen nicht nur auf freiem Feld produziert, sondern auch in Gewächshäusern, welche teilweise auch für kontinuierlichen Betrieb eingerichtet sind.
Es wurde gefunden, dass die erwähnten Abfallprodukte, d. h. Kohlensäure und Wärme, diesen Grünkulturen zugeführt werden können, wodurch eine beträchtliche Mehrproduktion erhalten wird. Die aus den Bioreaktoren ausströmende, kohlensäurehaltige Abluft wird in Rohrleitungen beispielsweise Freikulturen oder Gewächshäusern zugeführt. Sie kann auch in Wasser gelöst als gleichzeitige Bewässerung zu den Kulturen gebracht werden. In Gegenden, in welchen zu wenig Wärme für solche Kulturen vorhanden ist, kann die Abwärme vom Kühlsystem der Bioreaktoren ebenfalls diesen Kulturen durch ein Zirkulationssystem zugeführt werden.
Es ist also eine Kombination von Bioreaktoren mit Grünkulturen, bei welcher die Grünkultur die Abfallstoffe der Bioreaktoren ausnützt. Es soll noch erwähnt werden, dass als Grünkultur auch die Grünalgen gemeint sein können, welche CO2 verwerten und neuerdings in submersem Verfahren, d. h. in Wasser, gezüchtet werden. In diesem Fall wird das
Abgas der Bioreaktoren in die wässerige Phase eingeblasen.

**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
The invention relates to a method for the biological utilization of waste materials and / or waste heat from bioreactors, for example from fermenters.
It is known that bioreactors - especially for the production of microorganisms which are used as food and feed - produce large amounts of carbonic acid on the one hand and correspondingly large amounts of heat as waste on the other. Depending on which nutrient substrates are used for the mostly aerobic fermentation, 3000 to 10,000 kg of Cal per kg of dry matter produced and a correspondingly large amount of carbonic acid are produced. The heat must be dissipated through appropriate cooling, and the carbon dioxide leaves the reactors in the exhaust air. As an example, it should be mentioned that a bioreactor with a net volume of 200 m3 in which feed yeast is produced. and which produces around 20,000 kg of dry yeast per day, at a ventilation rate of 1.5 volumes of air per minute, emits 432,000 m3 of exhaust air daily.
This exhaust air contains - depending on the product - 2 to 10% carbon dioxide gas. It is an enormous amount of CO2 that is being released into the atmosphere. On the other hand, the aforementioned cooling - also depending on the product - has to dissipate around 60 to 200 million kg of cal heat per day.
The yeasts mentioned, or bacteria and fungi, are known to be produced in the above manner to an ever greater extent as food and feed. Since now many times in those countries. In which such artificial protein products have to be manufactured, the other plant-based food and feed are also missing - or at least in short supply, it would be interesting to achieve a symbiosis between bioreactors and green cultures.
The object of the invention is the utilization of unused waste products from bioreactors for green crops.
The object is achieved according to the invention by a method. that these waste products are fed to green cultures as growth factors.
The subject matter of the invention is explained below by way of example.
While the protein-producing microorganisms produce carbonic acid and heat as waste products, green plants need large amounts of these two waste products for their growth. Recently, such green crops have not only been produced in the open, but also in greenhouses, some of which are also set up for continuous operation.
It has been found that the mentioned waste products, i.e. H. Carbonic acid and heat can be supplied to these green crops, whereby a considerable additional production is obtained. The carbonic acid-containing exhaust air flowing out of the bioreactors is fed in pipes, for example, to free cultures or greenhouses. It can also be dissolved in water and brought to the crops for simultaneous irrigation. In areas in which there is too little heat for such cultures, the waste heat from the cooling system of the bioreactors can also be fed to these cultures by a circulation system.
It is therefore a combination of bioreactors with green cultures, in which the green culture uses the waste materials of the bioreactors. It should also be mentioned that the green algae can also be meant as green culture, which utilize CO2 and recently in a submerged process, i.e. H. in water. In this case it will
Exhaust gas from the bioreactors is blown into the aqueous phase.
