Solid Waste Management TRIZ Cases
- Field Soil Classification Data Fusion Without Lab Equipment
Simple field tests and a neural network replace complex laboratory workflows for soil classification in compressed earth block production.
- Raw Rice Husk Building Material for Thermal Insulation and Strength
To reduce concrete’s environmental impact, raw rice husks, binder, and water create hardened products with insulation and strength.
- Perovskite-Derived Cement Additive for Reduced Clinker Use
Industrial waste-derived calcium sulfate and silica replace clinker and natural gypsum while supporting cement strength and faster setting.
- Hybrid-Treated Plastic Granules for Asphalt Binder Compatibility
Microwave treatment and carbon nanoparticles modify waste plastic surfaces, reducing phase separation in asphalt or concrete binders.
- Blended Supplementary Cementitious Materials for Early Strength
Fine and coarse natural-pozzolan fractions are blended without intergrinding to improve early strength, reduce water demand, and support durability.
- Cement Slurry Modeling for Low-Carbon Well Barriers
Property and carbon-footprint models screen cement compositions that meet wellbore barrier requirements while reducing production emissions.
- Fly Ash Carbon Burnout Through Integrated Thermal Treatment
Thermally treat recovered fly ash, burn out carbon, and mix hot ash with a second portion to cool it while reducing moisture and disposal risks.
- Reactive Lime and Magnesia Concrete Densification for Crack Control
CO2 and water densify concrete with reactive lime or magnesia at low temperature, forming carbonates that limit expansion and cracking.
- Recycled-Material Structural Concrete for Lower Density and Insulation
Combines recycled lightweight aggregates with CSA cement, grout, and fiberglass rebar to balance low density, insulation, and structural strength.
- Basalt Fiber-Reinforced Concrete With Excavated Aggregate for Crack Resistance
A 0.2% chopped-basalt-fiber mix with crushed gneiss aggregate improves toughness and crack resistance in engineering lining concrete.
- Binder-Free Refractory Brick Carbonation for Foundry Casting
CO2 carbonation converts MgO into MgCO3, forming binder-free refractory bricks while reducing harmful vapors and supporting material recovery.
- Containerized Concrete Batch Plant for Rapid Jobsite Relocation
Modular silos, conveyors, a two-shaft mixer, and pumping equipment remain contained during transport, reducing setup effort between construction jobsites.
- Magnesium Fly Ash Porous Sound-Absorbing Material with Hydrophobic Surface
Physical foaming creates a low-density magnesium sulfate cement and fly ash structure, while vapor deposition hydrophobically modifies the surface for weather resistance.
- Cement-SCM Fraction Classification for Particle Packing and Early Strength
Air classification and optional milling divide cement and SCMs into targeted PSD fractions that improve packing, early strength, and water demand.
- Discarded Power Plant And Foundry Sand Recovery for Reuse
Landfill disposal and natural-sand depletion are addressed by pretreating, drying, and after-treating discarded power plant and foundry sand for reuse.
- Low-Carbon Clay Binder Formulation for Cement-Equivalent Strength
Dehydrated raw clay and deflocculation address the strength-carbon tradeoff, enabling binder properties comparable to Portland cement with 30-85% fewer emissions.
