| Abstract Scope |
Cold sintering and other methods may be useful as low-cost and low-energy methods to briquette fines from the recycling stream that are currently not used in the cullet stream. The use of cullet significantly lowers energy use to produce consumer glass, and 20 to 30% of glass cullet is lost to fines. Purified fines from post-consumer glass are generally not used due to small bubbles being formed, which would require an unreasonable quantity of fining agents to be added to the melt. Previous work has been done with sintering glasses using the hydrothermal hot press technique, but cold sintering has shown to be a viable method for glass sintering in recent years. We show the chemical analysis of a range of commercial glasses and glass-ceramics and demonstrate the required cold sintering parameters needed to get porous vs. dense briquettes using both purified and unpurified cullet fines. |
