1. CO₂ Emissions Reduction

1.1 Methodology

Turash uses GHG Protocol-compliant calculations for CO₂ emissions avoidance from industrial symbiosis exchanges. The platform tracks:

1. Waste Heat Recovery - Displacing fossil fuel-based heating/cooling
2. Material Reuse - Avoiding virgin material production
3. Water Recycling - Reducing energy-intensive water treatment
4. Waste Diversion - Avoiding landfill methane emissions

1.2 CO₂ Calculation Methods

Heat Recovery (Primary Impact - Year 1 Focus)

Formula:

CO₂ Avoided (t) = Heat Energy Recovered (MWh) × Grid Emission Factor (t CO₂/MWh) × Conversion Efficiency Factor

Parameters:

• Grid Emission Factor: 0.3 t CO₂/MWh (EU average, 2025)
• Conversion Efficiency Factor: 0.9 (accounting for heat exchanger losses)
• Source: European Environment Agency (EEA) grid mix data

Calculation Example:

• 500 GWh waste heat recovered (Year 1 target)
• CO₂ Avoided: 500 GWh × 0.3 t CO₂/MWh × 0.9 = 135,000 t CO₂ (Year 1)

Conservative Estimate (accounting for variable demand):

• 100,000 t CO₂ avoided (Year 1, realistic with 70% utilization rate)

Material Reuse & Waste Diversion

Formula:

CO₂ Avoided (t) = Waste Diverted (t) × Production Emission Factor (t CO₂/t) × Waste-to-Energy Credit (t CO₂/t)

Parameters:

• Production Emission Factor: Varies by material (steel: 2.0, concrete: 0.3, plastics: 2.5 t CO₂/t)
• Waste-to-Energy Credit: 0.2 t CO₂/t (avoided landfill methane)
• Average Material Impact: 1.5 t CO₂/t (blended across materials)

Year 1 Example:

• 50,000 t waste diverted
• CO₂ Avoided: 50,000 t × 1.5 t CO₂/t = 75,000 t CO₂

Water Reuse

Formula:

CO₂ Avoided (t) = Water Reused (m³) × Treatment Energy (kWh/m³) × Grid Emission Factor (t CO₂/MWh) / 1000

Parameters:

• Treatment Energy: 0.5-1.5 kWh/m³ (typical industrial water treatment)
• Average: 1.0 kWh/m³
• Grid Emission Factor: 0.3 t CO₂/MWh

Year 1 Example:

• 2.5 M m³ water reused
• CO₂ Avoided: 2.5 M m³ × 1.0 kWh/m³ × 0.3 t CO₂/MWh / 1000 = 750 t CO₂
