Innovative Food Waste Valorization Solution in Saudi Arabia: Tire-Biogas Residue Synergistic Sand Fixation and Planting System

Zero New Inputs

Direct synergy between waste tires and biogas residue.

Positive Ecological Loop

100 tons of food waste → 8.5 ha desert fixed annually + $430,000 annual revenue.

National Strategy Delivery

Advances Saudi Arabia's "Green Saudi" and "Circular Economy" Vision 2030 goals.

Overview

This solution, based on Saudi Patent No. SA1020254994, innovatively integrates biogas residue from food waste processing with waste tires to achieve three key objectives: desert greening, agricultural cultivation, and waste valorization. It directly supports Saudi Arabia's "Green Saudi" and "Circular Economy" Vision 2030 goals.

Core Advantages

🌱 Technical Compatibility: Precise Match Between Residue and Tires

Moisture Retention Advantage: Wet biogas residue (moisture content >40%) directly fills tires without pre-drying, meeting the initial water needs of climbing plants (e.g., date palms, Arabian jasmine).
Nutrient Supply: Complies with SASO-1993 organic fertilizer standards, providing slow-release N/P/K to support root establishment and vertical growth.
Micro-Climate Environment: Stacked tires create a nutrient-enriched zone for roots, significantly enhancing plant survival rates.

🌍 Ecological Benefits: Dual Stress Resistance

Synergistic Sand Fixation:
- Surface: Tire grid blocks wind, organic matter cements sand.
- Subsurface: Stacked structure anchors sand, microorganisms improve soil.
- Vertical: Framework for climbers + continuous nutrient supply.
Enhanced Water Cycle:
- Active Water Harvesting: Tire condensation collects 1066L/day (from 1333 tires).
- Passive Water Saving: Reduces irrigation demand by 40%.
- Plant survival rate increases from <30% to >65%.

💰 Economic Viability: Triple Revenue Streams

Direct Cost Savings:
- Eliminates dewatering: Saves $35,000/year in electricity (for 100 tons/day capacity).
- Replaces imported substrates: Saves $230/m³.
Derived Value Creation:
- Annual sand fixation: 8.5 hectares.
- Date palm cultivation revenue: $8,000/hectare/year.
Strategic Alignment:
- 100% utilization of waste tires (1333 tires/day).
- Organic waste valorization rate increases from <10% to 80%.

Validation Data (Saudi Environment Tested)

🔥 Material Resilience

Withstands extreme heat (60°C); tires remain intact, residue maintains 35–40% moisture.
No hardening, no nutrient loss.
