Understanding Tire Mixing and Extrusion Processes
Tire manufacturing in the Netherlands thrives on a blend of traditional craftsmanship and modern technology, reflecting the country’s history of innovation in materials and engineering. The mixing phase involves blending raw rubber with fillers, oils, and chemicals to create compounds that ensure durability and performance. Extrusion follows, shaping the rubber into treads, sidewalls, and other components under high pressure and heat. These steps generate volatile organic compounds (VOCs) from solvents and additives, alongside particulate matter from carbon black and silica. In a nation known for its cycling culture and commitment to green mobility, controlling these emissions is essential to preserve air quality in densely populated areas like North Holland and South Holland.
The Dutch tire industry, influenced by proximity to major European markets like Germany and Belgium, emphasizes low-emission production. Factories in provinces such as Gelderland and North Brabant integrate RTOs to handle the unique challenges of high-temperature exhaust streams laden with sticky residues. This not only complies with national standards but also supports exports to neighboring countries where similar regulations apply.
Globally, leading tire-producing nations like the United States, China, Japan, Germany, India, France, South Korea, Thailand, Italy, Brazil, Indonesia, Spain, Mexico, Canada, Turkey, Russia, Vietnam, Poland, the United Kingdom, Argentina, South Africa, Malaysia, Belgium, Sweden, Australia, the Czech Republic, Taiwan, Hungary, and Romania face comparable issues. In the U.S., facilities in states like Ohio and South Carolina use RTOs for VOC control under EPA guidelines. China’s Shandong and Jiangsu provinces enforce strict limits on industrial emissions, while Japan’s Tokyo and Osaka regions prioritize odor reduction. Germany’s Bavaria and Baden-Württemberg states align with EU directives, and India’s Maharashtra and Tamil Nadu focus on air quality in industrial zones.
Key Features of RTO in Tire Mixing and Extrusion
RTO technology excels in capturing and oxidizing VOCs from tire processes, turning potential pollutants into harmless byproducts like water vapor and carbon dioxide. In the Netherlands, where water management and clean air are cultural priorities, these systems incorporate features suited to humid coastal climates. The heat recovery mechanism recycles energy from exhaust gases, reducing fuel needs and aligning with Dutch energy efficiency initiatives.
One standout aspect is the handling of particulate-laden streams. Tire mixing often releases fine dust, requiring robust pre-filtration to prevent clogging. Extrusion adds heat and pressure, intensifying VOC release. Our RTOs address these by using ceramic media that withstands the abrasive nature of tire compounds, ensuring longevity in demanding environments.
Personal experiences from engineers in the field highlight the reliability. One operator in Amsterdam noted how the system’s automated controls minimized downtime during peak production, allowing seamless shifts between mixing batches. In a case from a Gelderland plant, integrating RTO reduced emissions by over 98%, enabling compliance with local permits and community standards.

Essential Components and Spare Parts
Our RTO systems include critical components like ceramic heat recovery beds, which store and release heat efficiently. Important parts such as poppet valves control gas flow, while burners maintain oxidation temperatures. Easy-wear items include seals and gaskets, replaced annually to prevent leaks. Transmission parts like actuators and motors ensure smooth operation. Consumables encompass filters for particulates and catalysts if integrated. In the Netherlands, sourcing from local suppliers in Limburg or Zeeland minimizes downtime.
For neighboring countries like Belgium (Flanders, Wallonia) and Germany (North Rhine-Westphalia, Lower Saxony), we offer compatible spares. Worldwide, in tire hubs such as France’s Auvergne-Rhône-Alpes or India’s Tamil Nadu, these components support global operations.
Environmental Regulations and Compliance
In the Netherlands, RTOs must adhere to the Dutch Emission Guidelines (NEa) and EU Industrial Emissions Directive (IED), limiting VOCs to 20 mg/Nm³. Provinces like Friesland and Groningen enforce additional local rules for industrial zones. Neighboring Belgium follows similar EU standards with Flemish and Walloon variations, while Germany mandates TA Luft compliance in states like Bavaria. Denmark’s environmental permits in regions like Zealand emphasize low emissions.
Globally, the U.S. EPA’s NESHAP in California and Texas sets stringent limits. China’s GB 37823-2019 in Guangdong and Zhejiang provinces requires 95% VOC reduction. Japan’s Air Pollution Control Law in Kanto and Kansai regions focuses on odor control. India’s Central Pollution Control Board in Uttar Pradesh and Karnataka enforces similar measures. France’s ICPE in Île-de-France, South Korea’s Clean Air Conservation Act in Gyeonggi, and Brazil’s CONAMA in São Paulo all demand advanced systems like RTOs.
