Catalyst recycling is crucial for several reasons: 1. Economic Efficiency: Catalysts, especially those based on precious metals, can be very expensive. Recycling these materials can substantially reduce operational costs. 2. Environmental Impact: By recycling catalysts, we can diminish the need for mining and processing raw materials, which often have significant environmental impacts. 3. Sustainability: Recycling supports the sustainable use of resources, ensuring that valuable materials can be reused multiple times before disposal.
