Solid Foundations. Resilient Performance.
At Pernis Refinery, we believe every part of the barrel has a purpose. Our Bitumen and Heavy Residue Processing operations transform what many consider the “bottom of the barrel” into high-value materials essential for construction, road infrastructure, waterproofing, and industrial sealing.
With advanced residue upgrading technologies and robust environmental controls, we help industries build better, longer-lasting infrastructure—while reducing waste and emissions.
What Is Heavy Residue Processing?
Heavy residues are the densest fractions remaining after crude oil distillation. Instead of discarding or burning these materials, Pernis employs cutting-edge processing units to convert them into:
-
Bitumen (asphalt) for roads and roofing
-
Fuel-grade residues for industrial combustion
-
Petroleum coke for metallurgy and cement kilns
-
Blending components for marine fuels
These products play a key role in building economies—literally.
Our Bitumen Capabilities
As one of the most trusted suppliers of bitumen in the European industrial corridor, Pernis delivers a diverse portfolio of grades, including:
▪ Paving Grade Bitumen
Used in highway construction, airport runways, and major roadworks. Engineered for durability, weather resistance, and long lifecycle.
▪ Industrial & Oxidized Bitumen
Ideal for roofing, sealing, and water-resistant applications. Formulated to meet ISO and EN standards.
▪ Polymer Modified Bitumen (PMB)
Enhanced elasticity, resistance, and longevity for heavy-duty use. Ideal for climates with extreme temperature shifts or heavy traffic load.
Our bitumen is lab-tested, batch-traceable, and delivered hot or packed, depending on client needs.
Heavy Residue Utilization
Our bottom-of-the-barrel strategy focuses on minimizing waste while maximizing product value. Here’s how:
-
Vacuum residue is processed into marine bunker fuel components.
-
Resid coke is used in cement kilns and steel furnaces.
-
Blending residues are integrated into fuel oil supply chains.
-
Oxidized residue streams support the roofing and waterproofing industries.
By turning residue into resource, Pernis helps close the refining loop—and reduce the environmental footprint.
Where Our Products Go
We serve a wide network of clients across Europe and beyond, including:
-
National and municipal road construction agencies
-
Waterproofing and insulation manufacturers
-
Roofing membrane producers
-
Heavy industries (cement, steel, ceramics)
-
Shipping companies (for residual marine fuel blends)
With multimodal logistics, we can meet large-volume demands with precision and speed.
Sustainability at the Base
Traditionally, heavy residue processing has been linked with higher emissions and environmental concerns. That’s why Pernis Refinery invests in:
-
Low-sulfur residue desulfurization
-
Closed-loop bitumen handling systems
-
VOC recovery technologies
-
Carbon tracking and reporting tools
-
Green alternatives to traditional coke and bunker fuels
We align all operations with EU carbon standards and refinery best practices to ensure every product supports a sustainable infrastructure chain.
