Environmental Progress
STX Group is a global environmental commodities trader offering physical and financial solutions across compliance and voluntary systems for energy, fuels, gas and carbon markets.
Used cooking oil (UCO) and recycled frying fat are collected from restaurants, food processors and industrial kitchens. Marine Olie connects collectors and processors through a reliable supply network.
Recycled frying fat and UCO are sustainable feedstocks for biodiesel, HVO and other biofuel production. Using waste oils reduces reliance on virgin vegetable oils.
Our supply chain ensures traceability and quality control from collection to delivery, supporting the circular economy in the oils and fats sector.
