The Bottleneck in Used Tire Management
A cargo unit transporting from Bangkok to Laem Chabang carries an average of 1,200 used tires per month, with an average disposal cost reaching €45 per piece. This physical flow has traditionally been managed as industrial waste, but the new MOU between NX Logistics Thailand and Thai Bridgestone has transformed the practice into a circular supply chain. The original route was interrupted at the Rayong customs checkpoint, where the tires were subject to environmental assessment and differentiated taxation. The logistics infrastructure has been reconfigured to separate the flow into two directions: one towards the retreading area, and the other towards thermal recycling plants. The net cost of treatment is reduced to €18 per piece thanks to material recovery.
The key mechanism is the differentiation between tires that can be retreaded and those that cannot, using a specific HTS code (9026.30) which allows tariff exemptions for materials destined for recycling. This reconfiguration has reduced the average customs clearance time from 7 to 2 days, freeing up approximately 180 tons of working capital per month that was previously immobilized in temporary storage warehouses.
Reconfiguring the Chain: From Waste to Value
The logistics flow has been redesigned to separate tires based on their suitability for regeneration. According to the agreement, 45,000 units per year are directed to internal regeneration processes at the Thai Bridgestone facility in Ayutthaya, while the remaining 120,000 are sent to authorized thermal recycling centers in Thailand and Cambodia. Transportation is managed by a new 8.8-ton electric truck, the first of the NX Logistics Thailand series, which operates from the Bangkok Logistics Center with an operational range of 200 km.
This change of direction has generated an estimated annual saving of €3.1 million for the company. The tariff difference between managing tires as waste (€45/unit) and as recyclable raw material (€18/unit) represents the main driver of change. Furthermore, the digital traceability of the units through a blockchain system integrated with the Thai Department of Environmental Quality Promotion portal has reduced classification errors by 67%, reducing administrative penalties.
Strategic Intervention: Circular Hub in Rayong
The implementation of the agreement took place through the reconfiguration of the Eastern Seaboard Logistics Center in Rayong, which now houses a section dedicated to pre-recycling processing. The center received an additional investment of €2.4 million for the installation of automated disassembly lines and spectroscopic analysis systems for early tire classification. This infrastructure is not only logistical: it serves as an intermodal hub between road transport, regional railways, and sea transport.
The competitive advantage lies in controlling regulatory variables. While competitors operating in a linear mode must face increasing pressure from EU legislation on the circular economy (Directive 2023/1856), NX Logistics Thailand has anticipated the change with an infrastructure that is already compliant. The risk of exposure to regulatory bottlenecks has been reduced by 74%, while operating margins have increased by 9.3% thanks to material recovery.
Impact on Margin: From Cost to Leverage
The narrative suggests that sustainability is a burden. The data shows that tire recycling has generated a net operating spread of +€1.3 per unit transported, with a direct impact on the cost of goods sold. The measured KPI is material conversion efficiency: from 28% in 0024 to 67% in 0026, with a reduction in non-valued losses from 91,000 to 39,000 units per year.
The paradigm shift is evident: the physical infrastructure, initially designed for disposal, has transformed into a generator of added value. The working capital immobilized in the logistics flow has been reduced by 42 days compared to the status quo, with a positive impact on ROIC of +5.8 percentage points. Circularity is no longer a compliance strategy: it has become the main lever for mitigating systematic risks related to global regulation.
