Recommendations (10)
Prioritize recycled-crystal architectural cladding (“cristalejos”) as the lead application and industrialize its production through resizing, alternative manufacturing routes, and installation refinements to reduce cost and improve adoption.
- Scope:
- Meso → Macro
- Time Horizon:
- Short → Medium
- Evidence Strength:
- Indicative
- Feasibility:
- Medium-High
Concentrate future product development on solutions where recycled crystal visibly preserves its core qualities—especially transparency/translucency, light refraction, and brightness—because these attributes drove the best evaluations.
- Scope:
- Meso
- Time Horizon:
- Short
- Evidence Strength:
- Indicative
- Feasibility:
- High
Implement traceability and end-of-life labeling for recycled-crystal products so they can be correctly routed, recovered, or reprocessed when they reach the end of their useful life.
- Scope:
- Macro
- Time Horizon:
- Medium
- Evidence Strength:
- Indicative
- Feasibility:
- Medium
Pursue price-parity strategies versus conventional alternatives—especially by industrializing production, resizing products, and simplifying processes—because market acceptance drops sharply when recycled-crystal products cost more.
- Scope:
- Meso → Macro
- Time Horizon:
- Short → Medium
- Evidence Strength:
- Indicative
- Feasibility:
- Medium
Design explicit end-of-life recovery solutions for crystal–cement composites before scaling urban products, since composite disposal was a recurring concern in the expert validation.
- Scope:
- Macro
- Time Horizon:
- Medium
- Evidence Strength:
- Indicative
- Feasibility:
- Medium
Expand architectural applications beyond the current prototypes to include exterior light-transmitting cladding, translucent roof/tile systems, and hydraulic floor surfaces incorporating recycled crystal.
- Scope:
- Meso → Macro
- Time Horizon:
- Medium
- Evidence Strength:
- Exploratory
- Feasibility:
- Medium
Investigate recycled-crystal products for urban mobility and comfort—such as directional signage, green-zone delimiters, drinking fountains, planters, tree guards, and beach/coastal equipment—taking advantage of the material’s resistance in saline environments.
- Scope:
- Macro
- Time Horizon:
- Medium
- Evidence Strength:
- Exploratory
- Feasibility:
- Medium
Test hybrid recycling routes that combine recycled crystal with other compatible industrial glasses and with rare-earth additives to generate new optical effects such as iridescence, fluorescence, or photoluminescence.
- Scope:
- Meso
- Time Horizon:
- Medium
- Evidence Strength:
- Exploratory
- Feasibility:
- Medium
Develop thermoformed textures and tactile/informational sign systems—including Braille and broadly understandable codes—to turn recycled crystal into accessible guidance and communication surfaces.
- Scope:
- Macro
- Time Horizon:
- Medium
- Evidence Strength:
- Exploratory
- Feasibility:
- Medium
Explore therapeutic and sensory-environment applications (for example Snoezelen-type settings) that use recycled crystal’s light, color, and texture effects as part of multisensory design.
