Powered by STX Group
As part of STX Group, Marine Olie operates within a broader global ecosystem of environmental commodities and climate markets.
This connection strengthens our ability to link physical feedstock flows with regulatory-driven and sustainability-led demand. While Marine Olie focuses on the sourcing, handling and processing of oils and fats, STX Group provides access to global trading networks, environmental products and market intelligence.
Together, this enables us to support customers across interconnected markets—where feedstock quality, logistics, sustainability criteria and regulatory frameworks increasingly shape demand and pricing.
Our History
Marine Olie was founded in 1967 as a trading company focused on fish oils, reflecting the market structure and demand at the time.
As global markets evolved, the company expanded into vegetable oils and fats, broadening its scope to serve a wider range of industries and applications.
Over time, additional capabilities such as storage, blending and laboratory analysis were introduced, allowing Marine Olie to respond to increasing requirements around product specifications, quality control and supply chain management.
The integration into STX Group in 2024 marks the latest step in this development—positioning Marine Olie within a broader market landscape where physical feedstocks and environmental commodities are increasingly connected.
What Matters to Us
We support the transition towards more sustainable value chains by enabling the use of renewable and waste-based feedstocks across different markets.
Our focus is on ensuring that these flows meet increasingly stringent sustainability criteria, while maintaining operational reliability and transparency across the value chain.
We continuously adapt our capabilities to meet evolving market and specification requirements.
Through blending, handling and analytical expertise, we enable feedstocks from diverse and variable supply sources to meet the consistent specifications required by end-markets. This allows customers to manage input quality, reduce operational risk and optimize performance in their applications.
We work in close collaboration with customers, suppliers and partners to optimize flows across sourcing, processing and end-use.
By combining market insight with operational capabilities, we support long-term relationships that create value through consistency, flexibility and reliable execution.
Quality in Practice
Quality is embedded throughout our operations, from sourcing and aggregation to blending and delivery.
Our laboratory capabilities allow us to analyze and monitor feedstock characteristics, ensuring that materials meet both customer specifications and regulatory requirements across different markets.
This integrated approach enables us to manage variability in upstream supply and deliver consistent, specification-compliant outputs suited to a wide range of applications.
