The process includes the step of extracting blood from at least one donor, manufacturing fibrinogen from the blood extracted in a known manner, dissolving the fibrinogen in a buffer, and effecting a sterile filtration of the buffer-dissolved fibrinogen by means of a static filtration device at a pressure of less than 0.5 atmospheres.

Abstract: Vermiculite which exists as the product of weathering of certain minerals, such as for example magnesium mica, is used after the technical expansion in a certain particle size smaller than 15 mm, preferably 3-6 mm, and a pouring weight which is smaller than 200 g/l, as an absorbent for animal excreta, for which it has excellent absorption characteristics. The water absorbing capability of the absorbent amounts to 400-600% (g/100g) of the original weight. By the addition of disinfecting agents a litter may be produced having bacteriocidal and fungicidal characteristics. Additionally added surfactant substances make the absorbent readily dispersible, so that it can be flushed without difficulties through e.g. a house toilet. By admixing of gypsum and/or clay powder a certain increase in the specific weight of the litter may be achieved, which thereafter no longer adheres even to very long-haired animal pelts.
