RECYCLING METHOD OF WASTE FISHNET
A recycling method of waste fishnet is provided. The waste fishnet is processed with steps of cutting, removing impurities, cleaning, and drying to form fishnet chips. The recycling method of waste fishnet includes the following steps. The fishnet chips are mixed with nylon-66, wherein the fishnet chips are of 70% by weight, and nylon-66 is of 30% by weight. The mixture is heated and molten. The molten mixture is then processed with the step of granulation. The grains are then processed with the step of spinning Thereby, the waste fishnet can be recycled and transferred into useful plastic materials.
Post-Consumer Scrap Film Recycling System and Process
A system for processing a supply of post-consumer scrap linear low density or low density polyethylene film into near-virgin quality blown film product. The system includes tearing the supply of film in a shredder, wherein the surface area of the film is exposed, including delaminating the film. The torn supply of film is washed in a hot water bath including a surfactant. The film is agitated in the bath containing the surfactant wherein contaminants on the film are removed from the film. The washed film is ground into smaller pieces and additional washing of the ground film in a rotating friction washer occurs wherein additional contaminants are removed from the film. The ground film is then dried in a dryer and compacted in a compactor without addition of water into granulated objects of near-virgin quality blown film product.
Improved method and system for reclaiming the individual components of a synthetic or artificial turf product
The present invention relates to an improved method and system for reclaiming the individual components of a synthetic or artificial turf product in a form almost similar to their original outset. The result is achieved by a method divided in three sections a first section in which the turf is downsized and dried, a second section where infill, such as rubber and sand, is separated and a third section where grass fiber and backing are separated.
PLASTIC RECYCLING METHOD FOR PROCESSING PLASTIC WASTE
A plastic recycling method for processing plastic waste, including providing a plastic waste mixture stream having, on the one hand, a variable proportion of 2D material and a variable proportion of 3D material and, on the other hand, an inhomogeneous density distribution, the proportions varying over time. Washing both proportions of the plastic waste mixture stream together. Shredding both proportions of the plastic waste mixture stream together while supplying a cleaning fluid. Density-based separation of the plastic waste mixture stream into at least two fractions, wherein the separation is performed as a function of a predeterminable density separation cut; and for at least one of the separated fractions: separating the fraction of 2D material and the fraction of 3D material from each other.
RECYCLING PROCESSING METHOD FOR WIND TURBINE BLADES
A recycling processing method for wind turbine blades, which uses an acidic degradation solution for recycling waste material from wind turbine blades, mainly using a hardware design that involves immersing waste material comprising composite material of fiberglass or carbon fiber in the acidic degradation solution, effectively causing the composite waste material to swell and separate to form degradable glass fiber cloth, which is finally cleaned and dried to achieve a glass fiber cloth with no surface residual glue and a resin degreasing rate of 99.6%. Accordingly, effectively achieving recyclables by carrying out a degradation process at normal temperature to save hardware costs, and enabling reclaiming the degradation solution using fractionation by distillation, which can then be reused. Hence, the recycling processing method has the advantages of involving a simple manufacturing process, high efficiency, and the ability to process waste materials on-site, without bearing the high cost of transportation.
Chemical recycling of processed mixed plastic waste streams
Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.
A METHOD FOR MANUFACTURING A COMPOSITE STRUCTURE USING RECYCLED FIBRE MATS
A method for manufacturing a composite structure (24), such as an epoxy composite structure, is disclosed Layers of fibre mats (13) are arranged in a mould (18), the fibre mats (13) comprising oriented fibres. A resin is infused in the layers of fibre mats (13), and the resin is cured to form the composite structure (24). The fibre mats (13) are recycled fibre mats (13), e.g. retrieved from an original composite structure, such as a wind turbine blade (6).
Methods for recycling plastic Nylon 6,6 from vacuum bags to obtain filaments or powder for 3D printing processes
Methods for recycling plastic Nylon 6,6 from vacuum bags to obtain filaments or powder for 3D printing processes. The method to obtain filaments includes a step of providing used Nylon 6,6 vacuum bags, a quality control step to check the status of the used vacuum bags, a step to form smaller parts, such as smaller pieces or pellets, from the used vacuum bags, quality control step to check the status of the smaller pieces or the pellets, an extrusion step wherein the smaller pieces or the pellets are introduced into an extruder, where they are melted, and the molten mixture is cooled and expelled through the die of the extruder to produce the recycled filaments, and a winding step wherein the recycled filaments that go out of the extruder are rolled up in coils.
