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

# 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:

-- 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:

-- 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';
