Chemical Recycling of Plastics

At Tate Metalworks, we recognize the pivotal role that chemical recycling is playing in the circular economy and how the storage tanks and reactors we fabricate and construct play a major part in the process and storage. Chemical recycling, also known as advanced recycling, is the practice of taking waste plastic and transforming it through depolymerisation, pyrolysis or other chemical processes back into raw materials that can be used again as part of the circular economy.

Our tanks and pressure vessels are essential for transforming the plastic feedstocks, intermediate products and final outputs throughout various stages of the recycling process. Our expertise in designing, fabricating and erecting storage tanks and vessels complements the intricate nature of chemical recycling, ensuring seamless operations and optimal resource utilization.

2. Batch Reactors and Continuous Stirred Tank Reactors:  These reactors are the most important part of chemical recycling. This is where the chemical reaction occurs that breaks down the plastic and returns it to its raw material. Tate Metalworks specializes in the engineering and design of ASME pressure vessels required for this process. 

3. Intermediate Product Storage: During chemical recycling processes such as depolymerization or pyrolysis, various intermediate products are generated, including monomers, syngas and liquid fuels. Our storage tanks offer the capacity and flexibility to store these intermediate products temporarily before further refining or utilization. This ensures continuity in the recycling process and allows for efficient management of production flows.

4. Final Product Storage: Once the chemical recycling process is complete, the resulting products, such as recycled monomers, oils or gasses, need to be stored before being transported to downstream facilities or end users. Tate Metalworks' storage tanks are designed to meet the specific requirements of each product, ensuring compatibility, safety, and integrity during storage. Whether it's storing purified monomers for polymerization or syngas for energy generation, our tanks provide reliable containment and preservation.

5. Batch Processing and Mixing: In some chemical recycling operations, batch processing and mixing of feedstocks or intermediate products may be necessary to achieve desired compositions or reaction conditions. Our storage tanks can be equipped with mixing systems and other ancillary equipment to facilitate batch processing, ensuring homogeneity and consistency in chemical reactions.
