Ensuring cold chains: Innovative approaches in modern food supply
Current developments and future trends in refrigerated and fresh food logistics
Refrigerated and fresh food logistics is a central component of modern food supply and is currently undergoing profound changes. Industry experts are observing rapid development in various areas of this specialized logistics sector, characterized by digitalization, sustainability, and market consolidation. The continuous expansion of logistics capacities reflects the growing market for temperature-controlled transport, while at the same time, stringent requirements for maintaining the cold chain present new challenges. Fresh food logistics, in particular, is establishing itself as an independent growth area with specific requirements and solutions. This report examines the current developments and future prospects of the industry, taking into account economic, technological, and environmental aspects.

Fundamentals of refrigerated and fresh food logistics
Cold chain logistics encompasses all logistical processes and activities related to the transport, storage, and handling of temperature-sensitive goods. Unlike conventional logistics, the primary focus here is maintaining a constant temperature to ensure the quality and safety of the transported products. Different temperature ranges are defined depending on the product group: frozen products require temperatures below -18°C, fresh products such as fruits and vegetables are generally transported between 2°C and 7°C, while pharmaceuticals often require adherence to precisely defined temperature windows.
Fresh food logistics, a sub-sector of refrigerated logistics, focuses specifically on highly perishable foods such as fresh fruit, vegetables, meat, and dairy products. In addition to temperature, other factors like humidity, ethylene concentration, and particularly short transport times play a crucial role. The particular challenge lies in the fact that the shelf life of these products is very limited, and any delay or interruption of the cold chain has an immediate impact on product quality.
The cold chain refers to the continuous temperature range maintained from producer to end consumer. Any interruption can not only lead to economic losses but also pose serious health risks. Therefore, refrigerated and fresh food logistics are subject to particularly stringent legal regulations. In Germany and the European Union, the German Food, Consumer Goods and Feed Code (LFGB) and the HACCP guidelines (Hazard Analysis and Critical Control Points) form the legal framework. The transport of foodstuffs is also governed by the regulations of the ATP Convention (Convention on the International Carriage of Perishable Foodstuffs), which sets specifications for vehicles and transport containers.
The economic importance of refrigerated and fresh food logistics is steadily increasing. Changing consumer habits, rising demand for convenience products, and the growing online grocery trade are driving market growth. At the same time, the industry places specific demands on infrastructure, from specialized transport vehicles and cold storage facilities to intelligent monitoring systems. These factors make refrigerated logistics a capital-intensive sector with high barriers to entry, which promotes market concentration.
Digitalization and automation as drivers of innovation
Digitalization is fundamentally revolutionizing refrigerated and fresh food logistics, opening up new opportunities for increased efficiency and quality assurance. Artificial intelligence (AI) is playing an increasingly important role in this process. Companies like Ecocool, for example, use AI algorithms to optimize the energy consumption of refrigeration systems and achieve significant electricity savings. These systems continuously analyze operating data, environmental conditions, and load profiles to control refrigeration units according to demand and avoid energy peaks.
Internet of Things (IoT) solutions form the backbone of modern cold chain monitoring. Miniaturized sensors record temperature, humidity, vibrations, and other parameters in real time and transmit this data to central monitoring systems. These telematics solutions, such as those used by the Swiss logistics company Krummen Kerzers, enable seamless documentation of transport conditions. Deviations from target values trigger an immediate alarm, allowing for timely intervention. Such systems have become indispensable, particularly in pharmaceutical transport, where temperature tolerances of less than one degree Celsius are sometimes required.
The automation of logistics centers is also progressing rapidly. Netto Marken-Discount, for example, has implemented largely automated processes in its new fresh produce warehouse. Driverless transport systems, automated high-bay warehouses, and picking robots increase efficiency while simultaneously reducing error rates. The automated systems operate around the clock and can process goods under constant temperature conditions, thus improving product quality. Furthermore, the precise control of the flow of goods minimizes the time products spend outside of optimal refrigeration conditions.
The networking of the entire supply chain through digital platforms represents another milestone. Integrated systems enable real-time data exchange between producers, logistics providers, and retailers. Thermotraffic, for example, has implemented a comprehensive digitalization strategy that involves all stakeholders in the cold chain and creates complete transparency. This not only facilitates the planning and control of goods flows but also allows for a faster response to unforeseen events such as traffic disruptions or technical problems.
Big data and predictive analytics unlock further optimization potential. By analyzing large datasets, logistics professionals can identify patterns and generate forecasts – for example, regarding goods volume, traffic flows, or the performance of refrigeration units under various conditions. This enables proactive capacity planning and preventative maintenance, minimizing downtime and reducing operating costs. Self-learning systems continuously improve their forecast accuracy, allowing for increasingly precise control of logistics processes.
Sustainability and emissions reduction as a key challenge
Refrigerated logistics faces particular challenges regarding environmental protection and sustainability. Conventional refrigerated transport generates significant CO2 emissions – both through vehicle fuel consumption and the additional energy required for refrigeration units. Furthermore, many older refrigeration systems still use refrigerants with high global warming potential. The industry is therefore under increasing pressure to improve its environmental footprint.
Electric drive concepts are gaining in importance. The Nagel-Group, for example, is increasingly relying on electric trucks for inner-city distribution. Ritter Sport is also increasingly using electric vehicles for the distribution of its temperature-sensitive chocolate products. The particular challenge with electric trucks in refrigerated logistics is that, in addition to traction, energy must also be provided for cooling. This requires larger battery capacities or innovative solutions such as separate energy storage systems for the refrigeration units. However, current developments show significant progress in the range and cost-effectiveness of these vehicles.
Alternative drive concepts such as LNG (Liquefied Natural Gas) and hydrogen are also being tested. The Swiss transport company Thurtrans has integrated LNG-powered refrigerated vehicles into its fleet, which have lower emissions than diesel vehicles. The company Stroetmann is testing hydrogen-powered vehicles for refrigerated logistics that produce virtually no local emissions. However, both technologies still face challenges regarding infrastructure and economic viability in everyday operation.
Innovative approaches to powering refrigeration units are being intensively researched. The Fraunhofer Institute is working on developing photovoltaic roofs for refrigerated trailers that use solar energy to power the units. This could significantly reduce external energy requirements and improve the environmental footprint. Electrically powered refrigeration units, which are supplied with electricity via the vehicle's engine or separate batteries while driving, are increasingly replacing conventional diesel-powered units. These systems not only produce fewer emissions but are also significantly quieter, which is a crucial advantage, especially for nighttime deliveries in residential areas.
Sustainable refrigerants are gaining importance. The industry is gradually switching to natural refrigerants such as ammonia, CO2, or propane, which have a significantly lower global warming potential than the previously used CFCs or hydrofluorocarbons. This transition requires, in some cases, considerable investment in new refrigeration systems and safety systems, but contributes to reducing environmental impact in the long term.
Optimized route planning and improved vehicle utilization offer further potential for emission reduction. Modern dispatching systems based on AI algorithms can consolidate the transport needs of different customers and calculate the optimal routes. This reduces empty runs and shortens distances traveled. Furthermore, innovative concepts such as city logistics are being tested, in which goods are consolidated at hubs on the city's outskirts and then delivered to city centers using environmentally friendly vehicles.
Market dynamics: Consolidation and investments
The refrigerated and fresh food logistics market is undergoing a period of intense consolidation. Large financial investors are increasingly recognizing the potential of this sector, leading to significant acquisitions. A prime example is the purchase of refrigerated logistics properties from the Nagel Group by the investment giant Blackstone. This transaction illustrates the growing interest in the specialized infrastructure of refrigerated logistics as an asset class. The Nagel Group can free up capital for its core business by selling its properties, while Blackstone benefits from the stable returns and long-term leases.
Market consolidation is also taking place among logistics service providers themselves. The Austrian company Müller Transporte acquired Fedl Kühllogistik to strengthen its market position in the Alpine region. Hellmann expanded its portfolio through the acquisition of a joint venture for fresh food logistics and HPL Apollo, thereby increasing its expertise in temperature-controlled transport. Particularly noteworthy was UPS's entry into the European refrigerated logistics market through the acquisition of Frigo-Trans and BPL. These acquisitions demonstrate that global logistics groups have also recognized the growth potential of refrigerated logistics and are entering this specialized market. FM Logistic took over transport for the food company Mondelez in Italy, reflecting the increasing integration of trade and logistics activities.
The refrigerated logistics industry is experiencing impressive growth. According to industry analyses by trans.info, the market is growing continuously at rates between 5 and 7 percent annually. This growth is driven by various factors: the increasing demand for fresh and frozen foods, the growing online trade in temperature-controlled products, and stricter regulatory requirements that necessitate specialized logistics solutions. Thermologistic is one example of a specialist company that is benefiting from this trend and pursuing a significant growth trajectory.
The positive market development is also reflected in substantial investments. A new cold storage center is being built in Bad Hersfeld with an investment volume of €25 million. The Nagel Group is expanding its logistics facility in Nuremberg to meet increasing demand. Major retail chains are also investing heavily in their fresh food logistics: Edeka and Rewe are building new fresh food centers to strengthen their competitiveness in the quality-oriented fresh food segment. These investments demonstrate the companies' confidence in the long-term development of the temperature-controlled logistics market.
The internationalization of cold chain logistics is also progressing rapidly. European providers are expanding into new markets, particularly in Eastern Europe and Asia, where the growing middle class is generating increasing demand for high-quality, fresh food. At the same time, supply chains for fresh produce are becoming increasingly global: fruit and vegetables from various climate zones are in demand year-round, requiring complex intercontinental cold chains. This development places high demands on logistics service providers, who must guarantee uninterrupted cold chains across long distances and various modes of transport.
New business models are emerging as a result of digitalization and changing market demands. Specialized last-mile delivery providers are developing solutions for delivering temperature-controlled goods directly to end customers. Platform-based approaches enable the flexible brokering of transport capacity for refrigerated goods, similar to Uber for refrigerated logistics. Pay-per-use models are also gaining importance, where refrigerated containers or units are no longer purchased but rented on demand. These new business models promote industry flexibility and lower the barriers to entry for smaller providers.
Challenges and risk management in the cold chain
Maintaining an uninterrupted cold chain is a key challenge for the industry. Any deviation from the prescribed temperature conditions can have serious consequences – from quality losses to significant health risks for consumers. The causes of cold chain disruptions are manifold: technical defects in refrigeration units, power outages in storage facilities, human error during loading, or insufficient cooling during transshipment between different modes of transport. Particularly critical phases are the transfer points between the various actors in the supply chain, where responsibility changes and waiting times often occur.
The numerous product recalls of recent years highlight the risks of interrupted cold chains. Examples such as the recall of liverwurst or pesto due to cold chain disruptions demonstrate that even established manufacturers face these challenges. Such incidents not only incur significant direct costs for the recall and destruction of the affected products, but can also lead to long-term reputational damage for the companies involved. Reports of unrefrigerated food products in stores are particularly alarming, as they may indicate systemic problems within the cold chain.
Quality assurance and control are therefore becoming increasingly important. Modern quality management systems include continuous temperature monitoring, regular audits of logistics processes, and comprehensive training for all employees who handle temperature-sensitive products. The industry is also developing stricter standards for the transport of temperature-controlled goods, exceeding the minimum legal requirements. These higher standards are often documented through certifications such as GDP (Good Distribution Practice) for pharmaceutical products or IFS Logistics for food products and are verified by independent bodies.
Innovative technologies support quality assurance. Time-temperature indicators can be attached directly to product packaging and indicate, through a color change, when a product has been exposed to elevated temperatures for too long. RFID tags with integrated temperature sensors enable seamless documentation of temperature conditions throughout transport. Advanced insulated bags with phase-change materials can compensate for short-term temperature fluctuations, thus ensuring product quality even during temporary interruptions of active cooling.
Risk management in the cold chain is evolving into a discipline in its own right. Companies are implementing systematic risk assessments, identifying critical control points, and developing contingency plans for various scenarios. Defining clear responsibilities and procedures for handling cold chain disruptions is particularly important. Crucially, companies must determine when and how affected products must be withdrawn from circulation and what documentation requirements exist for authorities. Insurance solutions specifically for losses due to cold chain disruptions are gaining in importance, with premiums increasingly tied to documented risk management and implemented monitoring systems.
The COVID-19 pandemic presented unique challenges for cold chain logistics, particularly in the transport of vaccines. mRNA vaccines required temperatures as low as -70°C, necessitating specialized transport solutions and meticulous monitoring of the cold chain. These extreme demands accelerated the development of ultra-low temperature refrigeration solutions and set new standards for risk management in pharmaceutical logistics. The experience gained and the technologies developed are now benefiting other areas of cold chain logistics and contributing to a general improvement in standards.

Fresh food logistics as a specialized growth market
Fresh food logistics is developing into a particularly dynamic sub-sector of refrigerated logistics. The focus is on products with a short shelf life, such as fresh fruits and vegetables, dairy products, fish, and meat. These product groups place special demands on the logistics chain: in addition to temperature, other parameters such as humidity or gas concentrations often need to be monitored, and short transport times play a crucial role in product quality. The growing demand for fresh, minimally processed foods, as well as the trend toward regional products, is driving the growth of this segment.
Optimizing structures and networks is central to many corporate decisions. Landgard, one of Europe's largest marketers of flowers, fruit, and vegetables, has comprehensively revamped its logistics network to shorten transport routes and improve product freshness. Veiling Rhein-Maas, a major auction platform for flowers and plants, has also optimized its logistics processes to minimize the time between harvest and sale. Large logistics providers such as Dachser, Nagel, and Nordfrost have established specialized fresh produce departments tailored to the specific requirements of these product groups.
New forms of cooperation and platforms are revolutionizing fresh produce logistics. Aldi Süd has developed its own platform for the direct sourcing of fresh fruit and vegetables to shorten the supply chain and improve freshness. The food retailer Greenyard relies on integrated supply chains where all steps from producer to retailer are seamlessly coordinated. This vertical integration enables better planning and shorter lead times, which offers crucial advantages, especially for delicate fresh produce.
Retailers are investing heavily in their fresh produce logistics to gain a competitive edge. Edeka and Rewe are building new, state-of-the-art fresh produce centers where temperature-controlled goods can be handled under optimal conditions. These centers are typically divided into multiple temperature zones to meet the varying requirements of different product groups. At the same time, automated conveyor technology and intelligent warehouse management systems increase process speed, minimizing the time from goods receipt to delivery to stores.
Specialized logistics providers for fresh produce are gaining in importance. Companies like AT Frischeservice have specialized in specific product groups and regions and offer customized solutions. Dairy specialist Karwendel has developed its own logistics solution tailored to the special requirements of its delicate products. These specialists possess the necessary expertise and infrastructure to safely transport and store even the most demanding fresh produce.
Innovative solutions for last-mile delivery present a particular challenge, especially in the growing online retail sector for fresh food. Delivery to end customers requires specialized vehicles with multi-compartment refrigeration systems capable of maintaining different temperature ranges. Furthermore, insulated transport boxes, cooling packs with phase-change materials, and intelligent packaging solutions are being developed that can also bridge longer waiting times (for example, when the recipient is absent). Delivery windows are being defined with increasing precision to minimize time spent outside optimal refrigeration conditions.
Future prospects of refrigerated and fresh food logistics
The future of refrigerated and fresh food logistics will be significantly shaped by technological innovations. Autonomous vehicles could play a crucial role in the medium term, especially given the acute driver shortage in the logistics sector. Initial pilot projects for self-driving refrigerated vehicles are showing promising results, although considerable technical and legal hurdles still need to be overcome before widespread deployment. Drones and autonomous robots are already being tested for the last-mile delivery of temperature-sensitive goods, particularly in areas with difficult access or for time-critical shipments such as medical samples.
New cooling and insulation technologies will further improve the efficiency and reliability of the cold chain. Vacuum insulation panels, which offer significantly better insulation than conventional materials at a lower thickness, could considerably increase the energy efficiency of refrigerated vehicles and containers. Thermoelectric cooling based on the Peltier effect offers potential for compact, low-maintenance cooling solutions without moving parts. Phase-change materials, which absorb or release heat when temperatures change, can act as thermal buffers and compensate for short-term interruptions in active cooling.
Blockchain technology could revolutionize transparency and traceability in the cold chain. By immutably documenting all relevant data – from temperatures and locations to responsibilities – in a distributed database, all stakeholders can view the status and history of transported goods at any time. This not only facilitates quality control but also compliance with regulatory requirements. Furthermore, smart contracts could automatically trigger payments or activate insurance benefits when certain conditions are met or violated.
Changing consumer habits will continue to shape the demands on cold chain logistics. The ongoing trend towards fresh, unprocessed foods is increasing the demand for efficient fresh food logistics solutions. At the same time, growing awareness of sustainability is increasing the pressure on the industry to develop more environmentally friendly solutions. Online grocery shopping, which experienced a significant boost during the COVID-19 pandemic, places particular demands on the delivery of temperature-sensitive goods directly to end customers.
Global warming presents additional challenges for cold chain logistics. Higher average temperatures increase the energy demand for cooling and place greater demands on the insulation of transport vehicles and warehouses. Extreme weather events such as heat waves can lead to peak loads on refrigeration systems. At the same time, global production and trade structures for agricultural products are changing, requiring adjustments to logistics networks. The industry must therefore develop resilience strategies to address these challenges.
Increasing regulatory density will continue to shape cold chain logistics. Stricter regulations for food safety, environmental protection, and climate neutrality require continuous adjustments to processes and technologies. The EU taxonomy for sustainable economic activities, as well as national and international climate protection laws, will increase the pressure on the industry to reduce its CO2 emissions. At the same time, these regulations also offer opportunities for innovative companies that adopt sustainable technologies early on.
