Abstract:
Devices and methods for directing a non-aqueous phase liquid (NAPL) that migrate entrained in a fluid (e.g., a gas) from sediments in bodies of water by using trapping caps having an upwardly sloped surface toward an accumulation zone that contains a water table, in which migration of the gas carries the NAPL toward the accumulation zone.
Abstract:
A pharmaceutical drug disposal kit includes a container for receiving pharmaceutical drugs. Water is added to the container to create an aqueous solution with the pharmaceutical drugs, and a constituent in the container makes the solution a basic aqueous solution. A visual and/or taste deterrent is disposed in the container, and an adsorbent or absorbent is also disposed in the container to provide at least partial solidification of the solution. A binding agent is also disposed in the container to bind the ingredients of the pharmaceutical drug, the deterrent, and the adsorbent/absorbent, thereby changing the physical state of the pharmaceutical drugs into a substance that is undesirable to consume, and which enables safe disposal of the pharmaceutical drugs.
Abstract:
Provided are methods for binding particulate solids in a polymer fiber matrix utilizing composite waste products. A mixture of composite waste products and particulate solids is formed into solid products to create degradation resistant solid units which capture the particulate solids.
Abstract:
A method for making a sound-insulating load-bearing floor, includes the following steps: applying a sound-insulating material over a load-bearing floor as to form a continuous coating layer; allowing the continuous coating layer to harden; applying a covering floor over said hardened continuous coating layer; wherein the sound-insulating material includes: 40% by weight to 95% by weight, preferably 60% by weight to 90% by weight, with respect to the total weight of the sound-insulating material, of at least one rubber in a subdivided form; 5% by weight to 60% by weight, preferably 10% by weight to 40% by weight, with respect to the total weight of the sound-insulating material, of at least one binding agent including: a first, component including at least one organic compound having at least one acid functional group or a derivative thereof, the first component having a Brookfield viscosity, measured at 23° C., of 0.1 Pa·s to 100 Pa·s, preferably 0.2 Pa·s to 50 Pa·s, more preferably 0.5 Pa·s to 20 Pa·s; and a second component including at least one metal oxide or hydroxide.
Abstract:
A process for producing a new material consists of utilising pieces of waste material which are to be discarded from a process of scrapping a product such as a vehicle where the product is passed through a shredding machine (12) which shreds, chops or fragments the product which is to be scrapped into small pieces and after at least part of the re-useable pieces have been recovered, mixing or coating (22) the remaining waste material with an encapsulating material for wholly or partially encapsulating the waste material therein to form a new composite material.
Abstract:
From one aspect, there is provided a method of treating a volume of plastics waste, the method including providing a volume of plastics waste comprising one of more plastics types, the or each plastics types having a melting point and a flash point and providing a heating zone having an entry zone through which the volume of plastics waste is feedable. The heating zone is brought to an operating temperature so as to avoid carbonisation of the plastics waste and the plastics waste is heated so that at least some of the plastics is melted to form a flowable plastics melt. The flowable plastics melt is caused to flow though the outlet under the influence of gravity into a cooling zone during which gas is allowed to escape to facilitate the flow. From another aspect there is provided an apparatus for treating a volume of plastics waste including a melt chamber defining a heating zone and heating means for heating the volume of plastics waste. The heating means includes a plurality of heating members which extend transversely to the flow of plastics waste and which are arranged to create a non-uniform thermal surface in the region of an inlet of the melt chamber.
Abstract:
The present invention provides a process for recycling waste FRP which can simply and effectively reuse waste FRP. This process comprises the steps of mixing a cellulose fine powder derived from wood, a resin powder, and an FPR powder derived from waste FRP, to obtain a mixture; and melting and molding the mixture into a given shape to prepare a molded resin product containing 10-65% by weight of said cellulose fine powder, 25-40% by weight of said resin powder, and 10-30% by weight of said FPR powder on the basis of the mixture.
Abstract:
A structural material formed of concrete-like substances which includes lead-including sand embedded within the structural material. One aspect bind the lead-containing sand using the biopolymer and/or a cross-linking agent. The biopolymers can be Xanthan gum, guar gum, and/or Chitosan. Different materials can be used for the cross-linking agent including boric acid. The materials cause the lead to be bound within a matrix within the structure, and prevent the lead from leaching out.
Abstract:
The invention relates to a method of preparing material to be further subjected to a heat and/or compaction treatment. The method comprises the step of—introducing the material in a plastic recipient (20) having an inner layer and an outer layer. The inner layer has a melting point lower than the temperature reached during the heat treatment, whereas the outer layer has a melting point higher than the temperature reached during the heat treatment.—closing the plastic recipient in such a way that the inner layer is not appearing at the outer surface of the closed recipient. The invention further relates to a method of disinfecting or sterilizing material.
