Solution Overview
Problem
Recycling glass waste containing organic matter often results in glass products of mediocre quality due to carbon particle inclusions and disrupts melting and shaping conditions, limiting the amount of waste that can be introduced into glass production methods.
Innovation Solution
A method involving a vitrifiable mixture of materials with organic matter, melted using submerged burners and supplemented with a solid oxidant, such as manganese dioxide, to produce high-quality mineral material suitable for glass melting without carbon particles and controlled redox levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If glass waste containing organic matter is directly recycled into glass production methods, then recycling effectiveness is improved, but carbon particle inclusions and mediocre quality result
Solution Approach 1:
The patent applies preliminary action by introducing a solid oxidant before the melting process to pre-oxidize organic matter in the glass waste. This preliminary oxidation converts carbon-containing compounds into carbon dioxide gas that escapes during melting, preventing carbon particle inclusions in the final glass product while maintaining high recycling effectiveness
Solution Approach 2:
The patent uses strong oxidants (such as nitrates, sulfates, or peroxides) to accelerate the oxidation of organic matter in the glass waste. This accelerated oxidation ensures complete combustion of carbon-containing compounds before melting, eliminating carbon particle inclusions and improving glass quality while maintaining high recycling rates
2Manufacturing precision
If glass waste containing organic matter is combusted before recycling, then organic components are removed, but an additional process step is required
Solution Approach 1:
The patent merges the oxidation of organic matter with the glass melting process by introducing a solid oxidant directly into the melting batch. This combination eliminates the need for a separate pre-combustion step, reducing process complexity while effectively removing organic components and preventing carbon particle inclusions in the final glass product
3Productivity
If large amounts of glass waste are introduced into glass production methods, then recycling effectiveness is improved, but melting and shaping conditions are disrupted
Solution Approach 1:
The patent uses strong oxidants to accelerate and complete the oxidation of organic matter in large amounts of glass waste before melting. This ensures that even when large quantities of waste are introduced, all carbon-containing compounds are converted to gas and escape, preventing carbon particle inclusions and maintaining reliable melting and shaping conditions
