摘要： A method of additive manufacturing is comprised of providing a material comprised of a ethyl cellulose polymer having an ethoxy content of 43% to 52% by mass and a plasticizer. The material is heated and dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base and successive layers of the material are adhered on the initial layer to form an additive manufactured part by repeating the aforementioned steps. The article formed of the ethyl cellulose polymer may be used in many applications such as those related to the pharmaceutical and food industries.

摘要： There are provided recycled polystyrene polymers having a melt flow index of less than about 25 g/10 min. There are provided processes for recycling polystyrene waste. The processes can comprise dissolving said polystyrene waste in p-cymene under conditions to obtain a polystyrene/p-cymene mixture, adding the polystyrene/p-cymene mixture to a hydrocarbon polystyrene non-solvent under conditions to obtain precipitated polystyrene and washing the precipitated polystyrene with additional portions of hydrocarbon polystyrene non-solvent under conditions to obtain twice-washed polystyrene. The twice-washed polystyrene can optionally be dried and formed into polystyrene pellets. There is also provided recycled polystyrene obtained from such processes for recycling polystyrene waste.

摘要： Provided are a composition for swelling pretreatment of a cured thermosetting resin material before decomposition, including a surfactant and an acidic material, and a method for swelling pretreatment of a cured thermosetting resin material before decomposition by using the same. When carrying out swelling pretreatment of a cured thermosetting resin material before decomposition by using the composition, it is possible to accelerate infiltration of the acidic material into the cured thermosetting resin material and swelling of the cured thermosetting resin material by virtue of the surfactant, and thus to increase the decomposition reactive surface area. Therefore, it is possible to increase reaction efficiency during the subsequent decomposition process, and to increase the decomposition ratio during the same period of time.

The method comprises mechanical removal of at least part of the glass (30, 40), placing residual waste (350) with glass particles in a vat (360) comprising a separation fluid (375) to produce a mixture of glass particles and polymer pieces from the residual waste, from which the polymer pieces can be screened off, washed and dried for reuse. The separation fluid (375) comprises water and at least one alcohol.

摘要： Methods for the recycling of carpet are disclosed that produce clean face fiber suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester or a polyamide, from carpets that includes a face fiber material and a backing material, and include the steps of heating the carpet to a temperature lower than the melting point of the face fiber material, but higher than the initial thermal decomposition temperature of the backing material, for a time and at a temperature sufficient to thermally decompose, pyrolyze, or oxidize at least a portion of the backing material, rendering the backing material friable, that is more friable than the untreated backing; and applying mechanical force to the carpet so as to liberate the friable backing material from the face fiber material.
