  • Patent number: 9517578
    Abstract: Method for manufacturing biodegradable moldings, in particular tableware and packages, with application of the method of evoking the water vapor pressure inside the mold consists in that loose bran, preferably the wheat bran, of granulation from 0.01 up to 2.80 mm in the amount of 95-100% of weight containing more than 14% of water structurally bound in the form of moisture, if needed, is mixed in the dry form with additional substances in the amount of up to 5% of weight in total, and the measured amount of dry material obtained in that way is placed in one of the parts of multipart mold, then the mold is closed and the mixture is subject to the simultaneous operation of temperature and pressure of the scope 1-10 MPa. The mold is heated up to temperature above 120° C., then the mold is closed, and then is depressurized, thus forming a gap between the edges of the mold not wider than 0.5 mm, and then the mold, if needed, is closed again, and the depressurization cycles are repeated.

  • Publication number: 20030068427
    Abstract: Material for making biodegradable mouldings, in particular table utensils and packaging containers according to this invention consists in 95-100% w/w of loose bran, in particular the wheat one, constituting a selected bran fraction of grain size from 0.01 to 2.80 mm containing from 7% to 45% of structurally bonded water in the form of moisture and possibly in up to 5% w/w of a mixture of impregnating substances and/or fragrance and/or aroma giving additives and/or non-fibrous fillers and/or moisture retaining agents and/or colouring additives. Method of making biodegradable mouldings, in particular table utensils and packaging containers, using grain grinding products consists in that the loose bran, in particular wheat one, of grain size 0.01 to 2.
