Evonik Turns Spent Catalysts into Assets, Keeping 113,000 Tons Out of Landfill
Evonik, a global leader in specialty chemicals, has pioneered a sustainable approach to managing spent hydroprocessing catalysts. Traditionally viewed as hazardous waste, these catalysts are now being transformed into valuable assets, reducing trash and emissions.
Refineries worldwide generate thousands of tons of spent hydroprocessing catalysts annually. Historically, these were sent to landfill. However, Evonik's catalyst acquisition program has kept over 113,000 tons out of landfill by repurposing them.
Evonik's approach involves a tiered pricing system based on the composition and condition of the spent materials. This allows refiners to benefit economically from the reuse of these catalysts. The process involves using the spent catalysts as feedstock for Excel Rejuvenation Technology, reducing waste and emissions. This method is gaining traction in the industry as a smarter alternative to traditional disposal methods.
Metal reclamation has become the standard in this process, recovering valuable metals like molybdenum, cobalt, and nickel. These metals can be reused in the catalyst or metal industry. Evonik's method includes a comprehensive evaluation of the reuse potential of spent catalysts, turning them into strategic assets. This helps refiners close the loop in their operations.
Evonik's approach to managing spent hydroprocessing catalysts has proven successful, keeping thousands of tons out of landfill and recovering valuable metals. By turning waste into assets, Evonik is helping refiners reduce trash, minimize CO2 emissions, and avoid mining virgin metals. This sustainable approach is not only beneficial for the environment but also economically viable for refiners.
