An arrestor bed for slowing an aircraft overrunning a runway, including an elongated excavation and a plurality of irregularly shaped foamed glass bodies at least partially filing the excavation. Each respective irregularly shaped foamed glass body has an aspect ratio between 1:1.6 to 1:1.7 and a diameter of about 1 inch. The irregularly shaped foamed glass bodies intersect to define stacking angles of about 35 degrees. Under compression, the irregularly shaped foamed glass bodies crush and break up before slip failure occurs such that the roadbed has a crushing failure mode.

Systems and methods are disclosed for landfill systems, comprising waste, a geosynthetic product, and a layer of foam glass aggregates interposed between the waste and the geosynthetic product.

Provided herein are processes for preparing glass powder product, the process including steps of: providing a crushing waste glass; sorting the crushed waste glass in a primary air classifier to provide a first stream and a reject stream, the first stream comprising a pulverized glass within a predetermined first particle size range and the reject stream comprising crushed waste glass excluded from the first stream; separating the reject stream based on size to provide a coarse stream and a fine stream, the fine stream having a predetermined second particle size range; and milling the first and fine streams to provide the glass powder product. Glass powder products, as well as systems for producing such glass powder products, are also provided.

A briquette for use as a mineral charge in a cupola furnace for the production of mineral wool fibres is produced by—combining: a) recycled waste mineral wool selected from i) waste mineral wool comprising uncured sugar containing binder, ii) waste mineral wool comprising cured binder, iii) waste mineral wool without binder and iv) combination thereof, b) cement, and c) additional sugar(s) to form a mouldable mixture and—moulding and curing the mouldable mixture to form the briquette.

The present disclosure relates to mineral wool compositions and articles, as well as methods for manufacturing mineral wool compositions and articles.

A glass ceramic and a preparation method thereof include a step of melting calcined electrolytic manganese slag to obtain molten glass. The molten glass is sequentially molded, nucleated, and crystallized to obtain the glass ceramic. The calcined electrolytic manganese slag is taken as a raw material, so that harmful gases are not generated in the raw material melting process, and secondary pollution is not caused. The preparation method provided by the present invention has the advantages of simple operation, high utilization rate of electrolytic manganese slag and low cost. Moreover, the prepared glass ceramic has good mechanical properties and corrosion resistance.

A system and method for processing leaded glass are presented, in which glass input is tumbled within the cylinder of a ball mill while it is being exposed to an electrolytic fluid. As the glass input is tumbled, balls within the ball mill pulverize the glass input into pulverized glass input particulate matter thereby exposing lead or other heavy metals contained within the glass input to a surface of the pulverized glass input particulate matter. The exposed lead or other heavy metals are largely dissolved by the electrolytic fluid leaving a mostly lead or heavy metal free pulverized glass input particulate matter. A reagent is applied to the pulverized glass input particulate matter to neutralize any residual lead or heavy metal within the pulverized glass input particulate matter thereby allowing the processed pulverized glass input particulate matter to pass a Toxicity Characteristic Leaching Procedure (TCLP) environmental test.

A method of recycling a composite material which comprises a mineral portion maintained within a thermoset resin, wherein the thermoset resin makes up at least 30 wt % of the composite material; and wherein the mineral portion makes up at least 30 wt % of the composite material comprises: introducing the composite material in granulated form into a mineral melt in a submerged combustion melter; providing additional heat energy to the mineral melt by combustion of the thermoset resin of the composite material within the mineral melt; and melting and incorporating the mineral portion of the composite material in the mineral melt by heat transfer from the mineral melt.

Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.

To provide a method for recycling a solar cell module glass, which enables development of other novel applications of a waste glass of a solar cell module while controlling an elution amount of Sb from the waste glass into water. Disclosed is a method for recycling a solar cell module glass, the method comprising: grinding a solar cell module glass into a glass powder; adding at least one foaming agent selected from SiC, CaCO.sub.3 and a seashell, and a particular inhibitor to the glass powder to produce a mixture; and heating the mixture to 700 to 1,100 C. to produce a foam glass.
