Practical Relevance Of Dissolution Kinetics In Recycled Cullet With Respect To Their Infuence On Container Glass Quality

Cullet recycling in the German container glass industry amounts to 2.7m tonnes cullet/year. The reuse of recycled cullet in the production of new glass containers is above 60%. The cullet ratio depends on the glass colour, the level of impurities, and on availability. The highest cullet ratio with more than 90% is realized for green glass. As a side effect of cullet waste management, the occurrence of metallic and ceramic impurities cannot be avoided.
