Sustainable practices in intralogistics operations

Sustainability and intralogistics: areas of technical intervention

Optimizing sustainability in intralogistics operations requires specific interventions across multiple fronts:

• Energy efficiency: implementing high-efficiency systems, such as synchronous reluctance or permanent magnet motors (IE4/IE5) in handling equipment, and adopting peak shaving strategies through Battery Energy Storage Systems (BESS). Smart lighting based on presence sensors and daylight harvesting completes the picture.
  
  
• Space optimization: maximizing storage density through solutions like vertical AS/RS systems or shuttle systems, increasing utilized volume and reducing the need for building expansion. This translates into reduced emissions associated with the construction and management of new spaces.
  
  
• Waste Reduction: minimizing picking and putaway errors through automated vision and robotics systems, applying FIFO/FEFO (First-In, First-Out/First-Expire, First-Out) logic via WMS, and intelligent inventory management to reduce obsolescence and returns.
  
  
• Eco-compatible materials and packaging: utilizing materials with post-consumer (PCR) or post-industrial (PIR) recycled content, or biodegradable/compostable solutions. Volumetric optimization of packaging through software algorithms reduces voids and material usage.
  

Enabling technologies for sustainability

Technological innovation drives the transition towards sustainable intralogistics, offering tools to measure, optimize, and reduce impact.

Automation Systems and Robotics

• Automated Storage and Retrieval Systems (AS/RS): these systems, particularly those equipped with regenerative braking motors, can feed up to 30% of the consumed energy back into the warehouse's electrical grid during descent or deceleration operations. Optimizing work cycles and planning through algorithms can further reduce energy demand.
  
  
• AGV and AMR: their energy efficiency surpasses that of traditional forklifts. The adoption of Li-ion batteries allows for shorter charging cycles (e.g., charging during micro-stops, "opportunity charging"), increasing operational autonomy and reducing dependence on non-renewable energy sources. Navigation systems based on SLAM (Simultaneous Localization and Mapping) and LiDAR contribute to more efficient routes and lower energy expenditure.
  
  
• Automated picking systems: robots equipped with 3D vision systems and artificial intelligence algorithms can identify and pick items with high precision, reducing picking errors (up to one error per 10,000, compared to one per 100 for manual picking), which translates into fewer returns and, consequently, less transport and packaging waste.

Management and data analysis software

• Warehouse Management Systems (WMS) integrated with sustainability modules: an advanced WMS can track and correlate operational data (movements, storage) with energy data (electric consumption per area/equipment) and environmental data (waste generated, emissions per unit moved). Integration often occurs via RESTful APIs or standard protocols like OPC UA, enabling granular visibility into consumption and the identification of inefficiencies.
  
  
• Predictive analysis and flow optimization: applying Machine Learning (ML) models to historical production and logistics data can optimize route planning (e.g., variants of the Traveling Salesperson Problem), load balancing, and fleet management, reducing kilometers traveled and energy consumption. Predictive optimization algorithms can also anticipate failures or anomalies in systems (predictive maintenance), reducing downtime and resource waste.
  
  
• Digital platforms for ESG transparency and reporting: utilizing platforms that support reporting standards like GRI (Global Reporting Initiative) or SASB (Sustainability Accounting Standards Board) facilitates the collection, analysis, and disclosure of ESG (Environmental, Social, Governance) data. Integration with blockchain technologies can ensure the immutability and traceability of sustainability information throughout the supply chain.
  
  

Renewable energies and intelligent management

• Integration of Photovoltaic Systems: installing solar panels on warehouse roofs (with efficiencies that can exceed 20-22% for monocrystalline modules) can meet a significant portion of the facility's energy needs, reducing the carbon footprint. Their integration with local microgrids ensures resilience and autonomy.
  
  
• Energy Storage and Management Systems (BESS): allow storing energy produced from renewable sources or drawn from the grid during lower-cost hours. These systems can perform peak shaving (reducing consumption peaks) and load balancing operations, optimizing energy costs and reducing grid pressure.
  
  
• LED Lighting and Efficient HVAC Technologies: LED lighting with motion and brightness sensors (daylight harvesting) can reduce energy consumption by up to 70-80% compared to traditional systems. Intelligent HVAC (Heating, Ventilation, and Air Conditioning) systems, integrated with the Building Management System (BMS), optimize climate control based on occupancy and external conditions.

Challenges in implementing sustainable intralogistics

Adopting sustainable practices and associated technologies in intralogistics, while advantageous, presents specific technical and operational challenges:

• Initial investments: acquiring advanced automated systems and upgrading infrastructure (e.g., solar panels, BESS) requires significant CapEx. Evaluation must consider the Total Cost of Ownership (TCO) in the long term and ROI.
  
  
• Integration with legacy systems: compatibility between new sustainable solutions (e.g., WMS with ESG modules, FMS for AGV/AMR) and existing IT and OT (Operational Technology) infrastructures can be complex. It requires developing robust API interfaces, using middleware (e.g., EAI platforms), and careful data mapping to ensure seamless information flows and reduce latency.
  
  
• Training and change management: introducing new technologies requires not only upskilling staff on specific technical skills (e.g., robotic maintenance, IoT sensor data analysis) but also a cultural shift towards a mindset oriented to sustainability and operational efficiency.
  
  
• Monitoring and measurement: defining clear performance indicators (KPIs) for sustainability (e.g., kWh/ton moved, kg CO₂/shipment) and implementing reliable systems for data collection, analysis, and reporting is crucial to assess progress and demonstrate value.

Best practices for integrating sustainability with a technical approach

To successfully address these challenges, a methodical and technically aware approach is essential:

• Detailed energy and environmental audit: conduct in-depth audits (e.g., compliant with ISO 50001) to identify major energy consumption and environmental impact sources. Use Life Cycle Assessment (LCA) methodologies for a holistic evaluation of products and processes.
  
  
• Progressive adoption of green technologies: plan the implementation of modular and scalable solutions, facilitating gradual integration into brownfield contexts. Focus on areas with a rapid ROI in terms of sustainability.
  
  
• Collaboration with technology providers: prefer partners who not only offer cutting-edge solutions but also demonstrate a commitment to sustainability through product certifications (e.g., EPD, Environmental Product Declarations) and a transparent supply chain.
  
  
• Continuous training and skill development: invest in technical training for staff on new technologies and awareness of sustainable practices, promoting a proactive approach.
  
  
• Monitoring, analysis and transparency: implement advanced data analytics systems to continuously monitor sustainability KPIs, use ESG reporting platforms to transparently communicate results, and leverage blockchain for the immutability of traceability data.

Addressing the challenges of investments, integration with legacy systems, and change management requires a technical-scientific approach and rigorous planning. Companies that navigate this complexity will not only contribute to a more sustainable future but also gain lasting competitive advantages, such as reduced operational costs, improved corporate reputation, and regulatory compliance, positioning themselves as industry leaders. Sustainability in intralogistics is an investment in the future that combines environmental responsibility with economic success.
