Pharmaceutical and Nutraceutical
Applications in dietary supplements, pharmaceutical excipients, and controlled-release systems
Potential Applications:
- •Detoxification supplements (adsorption of heavy metals and toxins)
- •Pharmaceutical excipients (carrier for active ingredients)
- •Controlled-release drug delivery systems.
- •Antidiarrheal agents and intestinal regulators
- •Mineral supplements (source of silicon and other trace minerals)
Relevant Technical Properties:
✓Cation exchange capacity (CEC) of 150–190 meq/100g
✓Chemical and thermal stability
✓Biocompatibility and low toxicity
✓Ionic selectivity for heavy metals.
Gas and Moisture Adsorption
In powder form, clinoptilolite adsorbs target gases and moisture through its microporous structure, without requiring a granular bed
Potential Applications:
- •Adsorption of VOCs and acid gases in industrial streams (use of powder in contact processes)
- •Moisture control as a powder desiccant (sachets and packaging materials)
Relevant Technical Properties:
✓Surface area of 39 m²/g (above the average of 14–30 m²/g)
✓Selective microporous channels (0.4–0.7 nm)
✓Thermal regeneration possible (up to 700°C)
✓Long service life and low operational cost
Other Industrial Applications
CLINOMAX™ clinoptilolite zeolite can be applied across many other industries
Potential Applications:
- •Industrial catalysts (catalytic support for chemical reactions)
- •Additives for plastics (flame retardant, UV stabilizer)
- •Paints and coatings (anti-corrosion functional additive)
- •Paper and pulp (fiber and filler retention)
- •Textile industry (effluent treatment and dyeing processes)
Relevant Technical Properties:
✓Purity 80–100% clinoptilolite (vs. 50–70% in common zeolites).
✓Low heavy metal levels guaranteed
✓Consistent and traceable supply.
✓Specialized technical support
Active Packaging and Preservation
As a powdered mineral filler, clinoptilolite adds adsorption functionality (ethylene, moisture, and odors) to packaging and materials.
Potential Applications:
- •Active packaging for fresh produce (adsorption of ethylene and moisture, helping to extend the shelf life of fruits and vegetables)
- •Desiccant sachets and moisture control agents.
- •Anti-odor filler in films and packaging materials
Relevant Technical Properties:
✓Adsorption of ethylene and moisture by the microporous structure.
✓Powder form (~#200) — integrates into films and mineral fillers
✓Natural, non-toxic, and inert mineral
✓Purity 80–100% clinoptilolite
Asfalto Morno (Warm-Mix)
As a powdered mineral additive, clinoptilolite releases structurally bound water above ~100 °C, foaming the binder and enabling asphalt to be mixed and compacted at lower temperatures.
Potential Applications:
- •Warm-mix additive: water released by the zeolite foams the asphalt binder, reducing mixing and compaction temperatures
- •Partial replacement of traditional mineral filler in asphalt mastics.
- •Lower-temperature process with the potential to reduce energy consumption and emissions at the plant
Relevant Technical Properties:
✓Reduction of approximately ~30 °C in mixing/compaction temperature (Woszuk & Franus, 2017)
✓Typical dosage around 5% of the binder mass (powder form)
✓Demonstrated in research with natural clinoptilolite, without the need for synthetic additives
✓Natural and non-toxic mineral
Industrial Effluent Treatment
Through batch cationic exchange, powdered clinoptilolite captures heavy metals and ammonium from industrial effluents, with marked selectivity for lead
Potential Applications:
- •Effluents from electroplating, tanning, textile and food processing industries (heavy metals and ammonium)
- •Removal of lead (Pb²⁺), copper (Cu²⁺), cadmium (Cd²⁺), and zinc (Zn²⁺) by ion exchange.
- •Ammonium (NH₄⁺) polishing as a complementary treatment step.
Relevant Technical Properties:
✓Selectivity order Pb²⁺ > Cu²⁺ > Cd²⁺ > Zn²⁺ (Ouki & Kavannagh, 1999)
✓Efficiency depends on the metal, pH and concentration — no single universal figure
✓Hexavalent chromium and nickel have limited removal by cationic exchange (pair with suitable metals)
✓Powder form (~#200) for batch adsorption or under agitation.
Composting and Sludge Stabilization
Added as a powdered mineral conditioner, clinoptilolite captures ammonium by ion exchange before it volatilizes, preserving nitrogen and reducing odors during composting.
Potential Applications:
- •Conditioner in the composting of sewage sludge and organic waste
- •Ammonium retention, with lower ammonia (NH₃) loss and reduced odor
- •Improvement of the final compost quality (nitrogen content and organic matter)
Relevant Technical Properties:
✓Reduction of ~25% in ammonia loss during sludge composting (Witter & López-Real, 1988)
✓Gain in %N, organic matter, and compost stability (Stylianou et al., 2008; ~20% w/w)
✓Reduces the bioavailability of metals in the final compost without removing them.
✓Powder form, natural and non-toxic mineral
