Abstract: A device for classifying a material mixture of multiple materials has a first transport unit into which the material mixture to be classified is deposited by a supply device. A second transport unit is arranged downstream. A first chute is provided between the first and second transport, via which a first material with a first fluid resistance can be separated from the material mixture. At least one third transport unit is arranged downstream of the second transport unit, such that a transit route for the materials is formed between the second and third transport units. A second chute is provided between the second and third transport units, via which at least the second material with a second fluid resistance can be separated from the material mixture. The third transport unit is designed so that material can pass through and/or a fluid flow can pass through.

Abstract: A method and device are used for separating particles of plastic foil from organic material. The device includes a chamber with a perforated wall. A mixture of particles of plastic foil and organic material is fed into the chamber through a feed opening. The mixture is set into a rotating movement inside the chamber by a rotor. In the vicinity of the perforations, the centrifugal force to which a particle is subjected is at least fifty times greater than the gravitational force to which the particle is subjected. An airflow is generated in the chamber parallel to the rotational axis of the rotor. Particles of organic material leave the chamber through the perforations. Particles of plastic foil are carried along by the first airflow and then discharge through an opening in the chamber.

Abstract: A beneficiation process and apparatus for the continuous treatment of comminuted woody biomass, particularly hog fuel, to substantially remove mineral impurities and bark and to recover white wood therefrom for use as industrial feedstocks.

Abstract: The method and systems efficiently extract recyclable materials from a mixed solid waste stream. The methods and systems use sizing, density and dimensional separation to produce intermediate waste streams that are enriched in particular recyclable materials. The recyclable materials can then be efficiently sorted from the individual intermediate streams using mechanized sorting equipment.

Abstract: Solid waste that includes a mixture of wet organic material and dry organic material can be are separated using mechanical separation to produce a wet organic stream enriched in wet organics and a dry organic stream enriched in dry organics. The separated wet organic stream and dry organic stream are separately converted to renewable or recyclable products using different conversion techniques particularly suited for the separated wet and dry organic streams.

Abstract: The invention provides a process for comminuting coal or other fuel solids in a shear field, and for optionally coating the solids with catalysts for combustion, liquefaction, and or gasification during the milling process. The process further provides for control of water content in the solids may be controlled before, during and after the milling in order to obtain micronized solids with fine hydration layers. The output fuel solids from the process can burn at low temperatures, avoiding emissions of nitrogen oxides, and they also have improved properties for surfactant-free suspension in either water or oil media, as well as for liquefaction and gasification.

Abstract: An absorbent composition of matter acts as a carrier for an active ingredient. The active ingredient is gradually released by the carrier in a controlled manner, which is compatible with the environment and current tendencies towards the use of organic and biodegradable products. The carrier is characterized as being particles obtained from the milling, separation, air wash and classification of the different fractions obtained from corncobs. The active ingredient is, for example, an essential oil, such as garlic oil or extract that may be combined with other essential oils for a synergistic effect that results in an improved insecticide/fungicide that is natural and contains no chemical additives. Alternatively, an artificially obtained substitute, for example, allyl isothiocyanate (AITC), can be used as a substitute for mustard seed oil.

Abstract: A new product is described characterized by its qualities to absorb undesirable scents present in the air, while serving at the same time as a carrier for aromas, fragrances, flavorings, repellents, attractants and other active ingredients. The active ingredients are gradually released by the carrier, which is compatible with the environment and current tendencies towards the use of organic and biodegradable products. The composition comprises a carrier and an active ingredient. The carrier is characterized as being particles obtained from the milling, separation, air wash and classification of the different fractions obtained from corncobs.

Abstract: A method for breaking down used materials or items, particularly wooden or motor-vehicle items, into reusable components with the use of fractionating tools, with which the accelerated parts of used material interact. The breakdown is effected selectively through impacts, deformation tension, bending stress, friction and/or shearing, with the shape and arrangement of the fractionating tools being set and/or matched to the structure and size of the used feed materials and/or the obtained recycled material.

Abstract: A system (30) and method for determining stock consistency and for using consistency as a process variable to control some aspect of operation of a refiner (32) used to refine stock. The system includes at least one sensor (70 or 180) from which some refiner characteristic is obtained that is used by a processor (38) in determining consistency. The method uses the characteristic, such as temperature or pressure inside the refiner or in a refining zone (304) of the refiner, along with at least one other refiner parameter in determining consistency. A controller (274) uses the consistency determined in controlling some aspect of refiner operation. In one preferred controller, consistency is compared with a consistency setpoint and adjustments are made to try to converge consistency with the setpoint. The controller can be paused to accommodate other changes made to refiner operation and released when steady state refiner operation is achieved.

Abstract: A method for recovery of branch knot wood and/or normal wood from oversize chips in which the oversize chips are ground to splinter, which then is dried and mixed with water, and then the sedimented splinter containing high concentrations of extractive substances and having a high specific weight is recovered and extracted in order to recover valuable extractive substances, particularly lignans. The lighter splinter floating up to the water surface is recovered in order to recover normal wood material for the pulp production.

Abstract: A method of rejuvenating and preserving a forest by transforming wood waste. Tree species are identified in a forest area. Equipment is then selected or modified based on the identified tree species. Wood waste of the identified tree species is gathered and transformed into useful wood derived end products with the selected or modified equipment. The wood waste may be transformed into wood charcoal and used as a fuel in a furnace to heat a boiler to produce steam. The steam is used to drive a turbine that runs an electric generator to produce electricity to run equipment that transforms the wood waste.

Abstract: A method and equipment manufacturing predetermined low bark content wood chips and a high bark content fuel fraction from wood chips with bark attached, includes mechanical bark removal treatment, in which the bark is removed from the chips and their size is reduced; pre-cleaning of the flow of chips with bark attached, into a flow of chips with a bark content of less than 10% and high bark content rejects, with the aid of pneumatic and mechanical sieving; final cleaning of the aforesaid wood chip flow from the pre-cleaning, with the aid of an optical separator, to create low bark content wood chips and a fraction with a higher bark content; collection of the rejects leaving the process, to create the aforementioned high bark content fuel fraction; and seiving out of the flow of wood chips, before the mechanical bark removal process, a predetermined thin fraction of the chips, which bypasses the debarking process.

Abstract: A recycling process for garbage containing a high proportion of paper where printed paper is first separated from the garbage. The garbage is then into pieces and light and heavy components are separated out in a classification tank. The remaining organic mass suspended in water is hydrolyzed and subjected to anaerobic digestion followed by aerobic co-composting. The resulting solid is a high grade fertilizer while biogas produced by the process is converted to electrical energy in a combined cycle installation.
