Abstract: A method for producing an object, wherein the method comprises drying the object or a primary product thereof, the object or a primary product thereof being at least partially dried in at least one drying device, wherein at least one of the at least one drying units contains at least one infrared radiator which is at least partially heated by means of biogas, a combustion gas selected from the group consisting of oxygen, air or other oxygen-containing gases is added to the biogas before said biogas is supplied to the at least one infrared radiator in order to heat said at least one infrared radiator, and the oxygen content in the waste gas resulting from the at least one infrared radiator being heated by means of the biogas is measured by means of a measuring device and the amount of combustion gas added to the biogas.

Abstract: The present invention relates to a method and to a device for continuous cleaning of process water circulating in a device for treating waste paper.

Abstract: The present invention relates to a method for cleaning process water circulated in a paper recycling system, comprising a process water treatment step, which comprises at least one pre-acidification step and at least one anaerobic cleaning step, wherein at least some of the process water to be cleaned is subjected to hydrolysis and acidification in the at least one pre-acidification step and the process water thus treated is then brought into contact with anaerobic microorganisms in the at least one anaerobic cleaning step in order to break down impurities in the process water, wherein at least one saccharide-splitting enzyme is added to the process water before or during the pre-acidification step, and the pH of the process water is set to 8.0 or lower at least during the at least one pre-acidification step and during the at least one anaerobic cleaning step.

Abstract: An apparatus for processing a rope formed in a pulper, comprising a conveying mechanism, in particular a winch, for pulling the rope, with the forward end first, out of the pulper, is characterized in that the conveying mechanism is positioned and designed in such a way that the rope can be fed, with the forward end first, directly to a shredder by the conveying mechanism.

Abstract: The invention relates to a conveyor system for conveying at least one material to be conveyed, comprising a continuously circulating conveyor, at least one transponder, preferably an RFID transponder, arranged on or in the conveyor, and at least one communication device for wirelessly transmitting data to the transponder and/or for wirelessly reading data saved in the transponder, said conveyor being a pocket conveyor belt. The conveyor preferably comprises a plurality of transponders arranged at regular intervals, wherein the data transmitted to the individual transponders or the data saved in the individual transponders preferably relates to information about a defined section of the conveyor, such as information relating to the type and/or amount of the material to be conveyed in a section of the conveyor assigned to the respective transponder.

Abstract: The invention relates to a device for processing composite materials containing fibers, in particular packaging materials containing fibers and in particular used beverage packagings. Said device comprises a double container, which comprises: an inner drum-like container having a hollow cylindrical drum body, which is closed by means of an end bottom at one of two end faces of the drum body and is open at an opposite end face of the drum body, wherein the drum body has screen holes at least on a section of the circumferential surface of the drum body, and wherein at least one baffle is provided at least on a section of the circumferential surface of the drum body and/or on the end bottom, and an outer container, which at least partially surrounds the drum body of the inner, drum-like container, such that an intermediate space is formed between the outer surface of the inner, drum-like container and the inner surface of the outer container, wherein the double container can be pivoted in the vertical plane.

Abstract: The invention relates to a method and a system for purifying process water, particularly for continuously purifying process water in the paper industry. The method comprises at least one process water treatment step, which comprises the following steps: a) an anaerobic purifying step, wherein process water to be purified is brought in contact with anaerobic microorganisms in an anaerobic reactor in order to decompose impurities present in the waste water, b) a first separating step, wherein gases present in the process water obtained in step a) are separated from said process water, and c) a second separating step, wherein solids present in the process water obtained in step b) are separated from the process water.
