Recycling of glass

Stuitevant Inc. produces three sizes of screen-type hammermiUs with 5 to 50 hp (4 to 37 kW) capacity, suitable for recycle of glass and... 

A pyrolysis technique was investigated as a method for the chemical recycling of glass fibre-reinforced unsaturated polyester SMC composites. The proeess yielded liquid products and gases and also a solid residue formed in the pyrolysis of glass fibres and fillers. The solid residue was used as a reinforeement/filler in unsaturated polyester BMC composites, and the influenee on mechanical properties was studied in comparison with BMC prepared entirely from virgin materials. 

Recycling of glass fibre-reinforced plastics is reviewed, with special emphasis on remelting of thermoplastic composites, mechanical recycling of thermoset composites, depolymerisation and dissolution of thermosets and thermoplastics, closed loop recycling of glass, and the use of glass as a mechanical compatibiliser. 32 refs.

For thermoplastic composites, the recycling of glass mat thermoplastics has been investigated. One possibility is to remelt GMT mould directly into new shapes. 

Each vehicle generates 500—800 pounds of residue. The aimual U.S. total is about 3.5 million tons or about 1.3% of the municipal soHd waste generated aimuaHy (3). The mixture is too complex to separate and recycle. Depending on the amount of glass, water, metal, and dirt present, the residue... 

In fact, recycling was a valuable U.S. industry for decades (witness the success of industrial recycling), especially in metals, newsprint, and some types of glass and aluminum cans. Only when regulators, in response to pubHc pressure, attempted to mandate the collection of materials that were in many instances expensive to collect and process did recycling begin to encounter problems.
