# Sustainability & SDG Compliance Implementation
|
||||
|
||||
## Overview
|
||||
|
||||
This document describes the implementation of food waste sustainability tracking, environmental impact calculation, and UN SDG 12.3 compliance features for the Bakery IA platform. These features make the platform **grant-ready** and aligned with EU and UN sustainability objectives.
|
||||
|
||||
## Implementation Date
|
||||
|
||||
**Completed:** October 2025
|
||||
|
||||
## Key Features Implemented
|
||||
|
||||
### 1. Environmental Impact Calculations
|
||||
|
||||
**Location:** `services/inventory/app/services/sustainability_service.py`
|
||||
|
||||
The sustainability service calculates:
|
||||
- **CO2 Emissions**: Based on research-backed factor of 1.9 kg CO2e per kg of food waste
|
||||
- **Water Footprint**: Average 1,500 liters per kg (varies by ingredient type)
|
||||
- **Land Use**: 3.4 m² per kg of food waste
|
||||
- **Human-Relatable Equivalents**: Car kilometers, smartphone charges, showers, trees to plant
|
||||
|
||||
```python
|
||||
# Example constants used
|
||||
CO2_PER_KG_WASTE = 1.9 # kg CO2e per kg waste
|
||||
WATER_FOOTPRINT_DEFAULT = 1500 # liters per kg
|
||||
LAND_USE_PER_KG = 3.4 # m² per kg
|
||||
TREES_PER_TON_CO2 = 50 # trees needed to offset 1 ton CO2
|
||||
```
|
||||
|
||||
### 2. UN SDG 12.3 Compliance Tracking
|
||||
|
||||
**Target:** Halve food waste by 2030 (50% reduction from baseline)
|
||||
|
||||
The system:
|
||||
- Establishes a baseline from the first 90 days of operation (or uses EU industry average of 25%)
|
||||
- Tracks current waste percentage
|
||||
- Calculates progress toward 50% reduction target
|
||||
- Provides status labels: `sdg_compliant`, `on_track`, `progressing`, `baseline`
|
||||
- Identifies improvement areas
|
||||
|
||||
### 3. Avoided Waste Tracking (AI Impact)
|
||||
|
||||
**Key Marketing Differentiator:** Shows what waste was **prevented** through AI predictions
|
||||
|
||||
Calculates:
|
||||
- Waste avoided by comparing AI-assisted batches to industry baseline
|
||||
- Environmental impact of avoided waste (CO2, water saved)
|
||||
- Number of AI-assisted production batches
|
||||
|
||||
### 4. Grant Program Eligibility Assessment
|
||||
|
||||
**Programs Tracked:**
|
||||
- **EU Horizon Europe**: Requires 30% waste reduction
|
||||
- **EU Farm to Fork Strategy**: Requires 20% waste reduction
|
||||
- **National Circular Economy Grants**: Requires 15% waste reduction
|
||||
- **UN SDG Certification**: Requires 50% waste reduction
|
||||
|
||||
Each program returns:
|
||||
- Eligibility status (true/false)
|
||||
- Confidence level (high/medium/low)
|
||||
- Requirements met status
|
||||
|
||||
### 5. Financial Impact Analysis
|
||||
|
||||
Calculates:
|
||||
- Total cost of food waste (average €3.50/kg)
|
||||
- Potential monthly savings (30% of current waste cost)
|
||||
- Annual cost projection
|
||||
|
||||

### Database Queries
|
||||
|
||||
**Waste Data Query:**
|
||||
```sql
|
||||
-- Production waste
|
||||
SELECT SUM(waste_quantity + defect_quantity) as total_waste,
|
||||
SUM(planned_quantity) as total_production
|
||||
FROM production_batches
|
||||
WHERE tenant_id = ? AND created_at BETWEEN ? AND ?;
|
||||
|
||||
-- Inventory waste
|
||||
SELECT SUM(quantity) as inventory_waste
|
||||
FROM stock_movements
|
||||
WHERE tenant_id = ?
|
||||
AND movement_type = 'WASTE'
|
||||
AND movement_date BETWEEN ? AND ?;
|
||||
```
|
||||
|
||||
**Baseline Calculation:**
|
||||
```sql
|
||||
-- First 90 days baseline
|
||||
WITH first_batch AS (
|
||||
SELECT MIN(created_at) as start_date
|
||||
FROM production_batches
|
||||
WHERE tenant_id = ?
|
||||
)
|
||||
SELECT (SUM(waste_quantity) / SUM(planned_quantity) * 100) as baseline_percentage
|
||||
FROM production_batches, first_batch
|
||||
WHERE tenant_id = ?
|
||||
AND created_at BETWEEN first_batch.start_date
|
||||
AND first_batch.start_date + INTERVAL '90 days';
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environmental Constants
|
||||
|
||||
Located in `SustainabilityService.EnvironmentalConstants`:
|
||||
|
||||
```python
|
||||
# Customizable per bakery type
|
||||
CO2_PER_KG_WASTE = 1.9 # Research-based average
|
||||
WATER_FOOTPRINT = { # By ingredient type
|
||||
'flour': 1827,
|
||||
'dairy': 1020,
|
||||
'eggs': 3265,
|
||||
'default': 1500
|
||||
}
|
||||
LAND_USE_PER_KG = 3.4 # Square meters per kg
|
||||
EU_BAKERY_BASELINE_WASTE = 0.25 # 25% industry average
|
||||
SDG_TARGET_REDUCTION = 0.50 # 50% UN target
|
||||
```
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Phase 2 (Recommended)
|
||||
1. **PDF Export**: Generate print-ready grant application PDFs
|
||||
2. **CSV Export**: Bulk data export for spreadsheet analysis
|
||||
3. **Carbon Credits**: Calculate potential carbon credit value
|
||||
4. **Waste Reason Tracking**: Detailed categorization (spoilage, overproduction, etc.)
|
||||
5. **Customer-Facing Display**: Show environmental impact at POS
|
||||
6. **Integration with Certification Bodies**: Direct submission to UN/EU platforms
|
||||
|
||||
### Phase 3 (Advanced)
|
||||
1. **Predictive Sustainability**: Forecast future waste reduction
|
||||
2. **Benchmarking**: Compare to other bakeries (anonymized)
|
||||
3. **Sustainability Score**: Composite score across all metrics
|
||||
4. **Automated Grant Application**: Pre-fill grant forms
|
||||
5. **Blockchain Verification**: Immutable proof of waste reduction
