Abstract: A composite material is formed by preparing mass particles consisting of a fibrous material at least partially derived from recycled post-consumer materials and preparing particles of a binding material consisting of a thermoplastic material at least partially derived from recycled post-consumer material. The prepared mass particles and particles of binding material are mixed together such that the binding material liquifies and coats the mass particles which are subsequently then pressed together to form a composite article in which the mass particles typically occupy between 35% and 60% by weight of the composite material and the binding material occupies between 40% and 60% by weight of the composite material. The composite material is suitable for replacing concrete, wood, or other construction, manufacturing or industrial materials, and possesses properties that in some applications may be equal or superior such materials.

Abstract: A biodegradable bioplastic may be formed from starch or cellulose. A carbohydrate may be reacted with chloroacetamide and further reacted with one or more cross-linking agents to obtain a bioplastic material. The bioplastic material may be insoluble in water, and/or hydrophobic and/or substantially transparent. The bioplastic material may be formed into numerous shapes and structures. The bioplastic material may have high toughness, flexibility and/or moldability whereby the material is suitable for further processing into a wide variety of different shapes and structures. The bioplastic material may also be utilized as a barrier or coating on paper or other substrates for food packaging and other applications.

Abstract: Medical Implant (100), comprising



a microbial cellulose tube (1), comprising a wall (2) having an inner surface (3) and an outer surface (4), wherein the wall comprises several layers (5, 6, 7) of microbial cellulose, wherein said layers are concentric or substantially concentric to a longitudinal axis (L) of the tube,
a stent (9) which placed inside of the microbial cellulose tube (1), wherein an outer surface (10) of the stent contacts the inner surface (3) of the microbial cellulose tube (1), and method for producing such implant.




The implant can be covered with newly created bile duct epithelium, thereby creating a new bile duct from body cells. The implant can be removed after completion of creation of the new bile duct. So, the implant as suitable as a temporary implant.
The implant can be used for surgery, such as surgery of gall bladder, bile duct and/or liver, e.g. gall bladder removal, hepatobiliary malignancy surgery or liver transplantation.
The implant can particularly be used for repairing or regeneration of bile duct. Further fields of use are the use as esophagus implant or urether implant.
