Glass recycling plant

The Glass Recycling Plant is a set of machines to produce Supersol, a pumice-like light porous foamed material, from waste glass produced in the local community as 99% of its basic materials.

The Glass Recycling Plant consists of 9 machine units, a bottle supply hopper, a bottle conveyor, a crusher, a cullet mill, powder conveyors, a powder sifter, a mixing machine, a baking machine and a Supersol sizer; and automatic control panels. The bottle supply hopper can hold about 4.5 m 3 of waste glass, which is crushed into cullet of less than 6 mm in size by the crusher. The cullet is then milled into glass powder with a median grain diameter of 35 µm by the cullet mill. The glass powder is sent to the powder sifter, which removes foreign objects and powder grains that are not of a specified size. The mixing machine mixes glass powder and add-in materials, and continuously sends the resulting powder mixture to the baking machine. There the powder mixture is preheated, softened, baked and foamed in the temperature range of 700 ~ 920 degrees centigrade. The layer of glass powder mixture having an initial thickness of 15 mm is converted into a light porous slab having a thickness of about 60 mm. More than 70% of these machines have originally been developed by Trim.

Most conventional glass recycling machines crushes glass only into cullet. The resulting cullet is used for making glass again if it is transparent or brown, and other cullet is mixed in secondary concrete products, asphalt paving and blocks. The cullet, however, is low-value-added products, and its use in business is limited. On the other hand, Supersol, produced by the Waste-Glass Recycling Plant, has a wide range of application, such as a light embanking material in civil engineering, a culture medium or an inorganic soil amendment in horticulture and agriculture, a purification material in water purification and an insulator in architecture. It is now used in various areas for various purposes.
