Glass Aggregate

The mineral and glass fraction of shredder residue — the part that carries no fuel value and no metal value — is often written off as the unavoidable ash. Ash melting changes that verdict by turning it into glass aggregate, a genuine construction product.

When the residue’s inorganic output is melted to fusion and cooled, it forms a dense, glassy slag. Ground to a controlled size, that slag becomes an aggregate usable where natural aggregate would otherwise be quarried.

From Ash to Asphalt Filler

At Klean’s automotive-shredder-residue reference plant, the molten glass product meets Japan’s stringent soil standards and, after grinding, is sold to the construction industry as asphalt filler. The material is not merely disposed of — it is specified into the built environment.

The environmental standard is the load-bearing detail. A vitrified slag is inert and non-leaching, so it can enter construction applications without the heavy-metal or leaching concerns that keep raw fly ash out. The melting step is what earns the material its market.

Every Fraction, a Product

The strategic point is completeness. When the mineral fraction becomes aggregate, shredder residue leaves no residue of its own — energy, metals and minerals all exit as outputs, and the landfill disappears from the material balance entirely.
