Abstract: A polishing slurry for semiconductor planarization containing cerium oxide particles and water, wherein the content of the cerium oxide particles having a diameter of 3 ?m or more is 500 ppm or less (weight ratio) in a solid, preferably 100 ppm or less and it is more preferable that D99 (99% by volume of the whole particles in polishing slurry) of the cerium oxide particles is 1 ?m or less. The polishing slurry can reduce the generation of scratches, and can polish a surface of the semiconductor substrate in the wiring formation process of semiconductor device precisely at a high speed.

Abstract: A method for automated destringing and breaking down of baled biomass material using limited manual labor is disclosed. The method includes selecting and moving one bale of biomass material from a stack of bales to an automated destringing station where the string is removed from that bale. The bale is then lined up next in line with previously processed destrung bales and advanced along a continuous process line through a bale chopper that breaks the biomass material down into useful pieces for further processing at the facility. In a preferred embodiment an automated initial quality control evaluation step can be provided with a bale rejection system operated on detected non-conforming bales before they are destrung.

Abstract: By utilizing specially processed waste carpeting as a filler in the production of carpet backcoating, roofing materials, or other similar products, the amount of waste carpeting that is landfilled or otherwise disposed of is significantly reduced as is the need for mining the mineral fillers. Waste carpeting (post-consumer and/or waste from new carpet manufacture) containing calcium carbonate and a thermoplastic resin is collected and size-reduced to a size corresponding to the size of calcium carbonate typically used as a filler. The size-reduced waste carpeting is added as filler to at least one other material, such as polymers in standard latex, EVA, or PVC carpet backcoatings, to provide a composite used in the manufacture of a useful product (like carpet backcoating), and then the composite material is used to make the useful product (such as carpet backcoating, which is used as a primary or secondary backcoating in the manufacture of new carpeting).

Abstract: Method for comminuting and cleaning waste plastic, in particular, mixed plastic (MKS) with the following steps: a compacted material, especially, an agglomerate is produced from film scraps or film remnants comminuted into flakes and/or thick-walled plastic parts chopped up into chips, the compacted material is introduced into a disc or drum refiner and is ground therein in the presence of water, wherein the portion of compacted material of the goods located in the refiner amounts to at least 10 percent by weight, a fine grain fraction is removed from the ground stock exiting from the refiner, the remaining ground stock is washed and either mechanically dewatered and dried, or pulverized again in a further refiner stage in the presence of water, and subsequently dewatered and dried.

Abstract: The present invention provides a recycler that recycles a printed circuit board for separating and retrieving a metallic material, which includes a printed metallic material, and an insulating material, both composing the printed circuit board. The insulating body base of the printed circuit board as the waste printed circuit board can be a thermoplastic resin or a mixture of thermoplastic resin and inorganic loading material. The recycler includes a pressuring device that pressurizes the waste printed circuit board, a heater that heats the waste printed circuit board to a predetermined temperature at which the waste printed circuit board is at least softened, and a filter that filters the resin material from the waste printed circuit board. The heater can be maintain the filter at the predetermined temperature provided by the heater.

Abstract: The invention relates to a process for recovering monomeric units of a nylon from carpet material. The carpet material includes fibres containing nylon bound to a backing containing one or more non-nylon components. The carpet material contains between 15 and 35 wt. % of the nylon. The process includes: a) mechanically separating the carpet material into an enriched carpet mixture containing between 35 and 55 wt. % of said nylon and into a depleted carpet mixture having a lower content of nylon than the carpet material; and b) exposing the enriched carpet mixture to conditions at which depolymerization of the nylon is effected.

Abstract: The invention relates to a process for separating tenaciously elastic materials such as plastics and rubber from materials tearing and/or defiberizing under high mechanical stress, particularly paper, and to a device for performing said process. The process is characterized in that the mixture of materials to be separated is subjected to high radial, axial and tangential acceleration forces, whereby a mass flow of shredded fibrous material and a mass flow of substantially unshredded plastics is withdrawn separately. The device for performing the process consists of a screen basket which is cylindrical or preferably polygonal in shape and has borings in its jacket to let the defiberized material pass through, a rotatable driving shaft being arranged coaxially inside the screen basket, with blades being attached to said driving shaft, preferably in rigid connection.
