摘要:
Beschrieben wird die Verwendung von modifizierten Abfallprodukten der Zellstoffgewinnung als hochwertigen Torfersatz, wobei die Rejekts aus der Zellstoffindustrie, gegebenenfalls nach Neutralisierung, beispielsweise mittels in der Zellstoffindustrie anfallender geeigneter Abwässer, gereinigt und als Ersatzmaterial für natürlichen Torf verwendet werden.
摘要:
The invention concerns a high-grade long-duration organic fertilizer and a method of manufacturing it by the oxidative ammonolysis of industrial lignin. The fertilizer contains nitrogen in the form of ammonium compounds, normally hydrolysable amides and more strongly bound organic nitrogen, the proportion of more strongly bound organic nitrogen being 55 to 85 %, preferably 65 to 80 %, relative to the total nitrogen content of the fertilizer. The manufacturing process uses industrial lignin precipitated under alkaline conditions from alkaline waste liquors, extracts or solutions. Preliminary tests have confirmed that this process gives a natural-like high-grade, long-duration fertilizer similar to humus in character and with surprisingly good environmental compatibility.

摘要:
Die Erfindung betrifft ein Verfahren zur Behandlung von Gülle, bei welchem die thixotropen Eigenschaften der Gülle durch Zusatz von Hemizellulosen und Zucker enthaltendem Calzium- oder Magnesiumlignosulfonat geändert werden und die derart aufbereitete, zum Teil desodorierte Gülle in mehreren Teilmengen auf ein organisches oder anorganisches Sorptionsmaterial aufgebracht wird, das zwischen den einzelnen Teilmengenzufuhren durchgemischt und durchgelüftet wird. Nach Aufbringen der gewünschten Güllemenge wird das entstandene Gemisch mit das Pflanzenwachstum günstig beeinflussenden Stoffen angereichert, und dieses Gemisch dient als Düngemittel mit geregelter Nährstoffdesorption, bestehend aus (nach Gewicht) 10 bis 50 Teilen geschroteten Abfällen auf Phytomassebasis, 30 bis 60 Teilen mit 1 bis 20 Teilen Calzium- oder Magnesiumlignosulfonat aufbereiteter Gülle, 0 bis 40 Teilen Kalkstein, 0 bis 20 Teilen Ammoniumsulfat und 0 bis 20 Teilen Phosphaten.
摘要:
The present invention primarily relates to a preparation comprising or consisting of 40 - 99.9 wt.-% of lignin, preferably unmodified lignin, 0.1 - 50 wt.-% of minerals, preferably 0.1 - 30 wt.-%, 0 - 25 wt.-% of one or more mono- and oligomeric carbohydrates, preferably 0.1 - 20 wt.-%, and 0 - 15 wt.-% of one or more solvents, in particular water, preferably 0.1 - 4 wt.-%. Furthermore, the present invention relates to a fertilizer comprising or consisting of such a preparation and to the use of such a preparation as fertilizer, as ingredient for a fertilizer or for producing a fertilizer.

This invention relates to high organic matter plant food products for agronomic uses. Also disclosed are combination products comprising the high organic matter plant food products, articles made from and incorporating same and methods of using same in agricultural operations for restoration and/or maintenance of organic matter values and/or nutrient values in soils, particularly certified organic farm soils.
摘要:
The present invention relates to a method for producing a soil improvment material. According to the invention such a material is produced by the steps of mixing wood fiber slurries from paper mills and fly ash from fossil fuel power and heating plants and of further treating the material to obtain a packetable product. The wood fiber slurry is treated to become an almost gruel-like slurry and is pressed through a sieve belt press (4) to become considerably dewatered, down to a water content of about 20 %, after which the slurry is pre-mixed with fly ash, after which the main mixing is carried out to obtain homogenous lump-like particles, which are subjected to a size reduction process through screening or the product after the main mixing and a possible size reduction process is pelletized. The invention also relates to an apparatus (1) designed to carry out the method as well as a soil improvement material obtained according to the method and by means of the apparatus respectively.
摘要:
The invention relates to a process for treating bleaching liquors from pulping processes based on organic acids. The process is characterized in that inorganic acid, such as nitric acid, phosphoric acid and/or sulphuric acid, is added into a bleaching liquor obtained from the bleaching or a stage closely associated with bleaching, whereby organic acids contained in the bleaching liquor are released into the bleaching liquor. The organic acids are then separated from the bleaching liquor and recycled to the cooking stage to be used as cooking chemicals. The nitrogen-, phosphor- and/or sulphur-containing product thereby produced, from which organic acids have been separated, is recovered to be used as a fertilizer or as raw material for a fertilizer.
