The ProCat story started with catalytic converters.

Before ProCat became a trusted supplier of automotive cores, the business began by buying catalytic converters, valuable parts that many people saw simply as scrap, but which still had real material value and an important role within automotive recycling.

That early focus shaped the business from the beginning. It taught us how to identify value in used automotive components, how to handle parts responsibly, and how to build relationships across the recycling and remanufacturing industries.

The name ProCat comes from those early days.

But as the business grew, so did the opportunity.

From Catalytic Converters to Automotive Cores

Over time, ProCat expanded beyond catalytic converters and began handling a wider range of automotive core parts.

What started with one specialist area developed into a broader operation supplying reusable and remanufacturable components to businesses across the automotive industry.

Today, ProCat supplies a wide range of automotive cores, including engines, gearboxes, diesel injectors, diesel pumps, AC compressors, alternators, starter motors, EGR valves and power steering parts.

The business has grown, but the principle has stayed the same; valuable automotive parts should be recovered, reused and returned to the industry wherever possible.

Built on Experience, Trust and Supply

From our base in Darlington, ProCat has developed into a family-run automotive core supplier working with customers across the UK, Europe and worldwide.

We support remanufacturers, reconditioners, garages, mechanics and automotive businesses that need reliable access to quality core stock. Whether a customer is looking for specific OE part numbers, mixed pallets, regular supply or volume orders, our role is to help them source the right parts efficiently.

In the remanufacturing industry, availability matters. Having the right core at the right time can keep jobs moving, reduce delays and help businesses serve their own customers faster.

That is why ProCat has become more than just a parts supplier. We aim to be a dependable supply partner.

Buying Core Stock from Businesses

ProCat is also an active buyer of automotive cores.

We work with garages, mechanics, rebuilders, brokers, suppliers and automotive businesses that have used cores, surplus stock or regular volumes available.

Whether it is a small batch, mixed pallets or larger quantities, our team can assess the stock, provide a valuation and arrange collection where required.

This buying side of the business continues the same idea that started with catalytic converters: identifying value in used automotive components and making sure they are handled properly within the recycling and remanufacturing supply chain.

If your business has stock available, visit our Sell to us page to arrange a valuation or submit details.

Supporting the Remanufacturing Industry

ProCat sits at an important point in the automotive supply chain.

We help connect businesses that have core stock with the remanufacturers and reconditioners who can give those parts a second life.

This supports a more efficient, more sustainable industry. Instead of valuable components being wasted, they can be recovered, sorted, supplied and rebuilt.

From engines and gearboxes to smaller specialist parts, automotive cores play a major role in keeping vehicles on the road while reducing the need for unnecessary new manufacturing.

ProCat also supports customers across Europe through our European Core Supply service.

Recycling Has Always Been Part of Our Story

Because ProCat started with catalytic converters, recycling has always been part of the business.

The automotive industry produces a huge volume of used parts, but many of those parts still have value. Through core recovery, recycling and remanufacturing, they can be reused instead of discarded.

This closed-loop approach helps reduce waste, conserve resources and keep valuable materials and components in circulation for longer.

You can learn more about our approach on our Recycling and Sustainability page.

Where ProCat Is Today

Today, ProCat has grown from a catalytic converter buyer into a trusted automotive core supplier.

From our Darlington warehouse, we buy and supply automotive cores across the UK, Europe and worldwide. We work with businesses that need fair pricing, reliable stock, straightforward communication and a team that understands the industry.

Our business has changed over the years, but our purpose has remained consistent; to recover value from automotive parts, support the remanufacturing industry and help keep usable components in circulation.

That is the ProCat story.
