Living Up to the Name: How PJ Circular Engineering Proves Its Climate Impact

July 31, 2025

When PJ Diesel Engineering rebranded as PJ Circular Engineering (PJCE), the goal was clear: signal a future-oriented commitment to climate-friendly and circular practices. But adopting the word “circular” wasn’t just a branding decision, it came with a responsibility to prove it. To confidently carry that name and meet compliance regulations, PJCE needed to document and quantify the climate impact of its remanufacturing processes.

PJCE specializes in circular engineering solutions for the maritime industry, focusing on extending the life of critical vessel components through high-quality remanufacturing. By giving parts a longer life, the company helps shipowners reduce costs, avoid downtime, and move toward more climate-conscious operations.

To support their new identity and reduce risk around sustainability claims, PJCE partnered with ReFlow to measure and verify the environmental benefits of remanufacturing. Through climate assessments, they can now clearly demonstrate the carbon savings achieved when customers choose remanufactured components over new ones.

Customer Overview

  • Company Name: PJ Circular Engineering
  • Industry: Maritime Service Manufacturer
  • Location: Denmark

Proving Circularity Is More Than a Name

For decades, PJCE has delivered remanufacturing solutions that extend the life of turbochargers, governors, and other maritime components, offering a lower-emissions alternative to new production.

But after rebranding, PJCE faced a new challenge: living up to the expectations built into their new identity. Customers, suppliers, and auditors increasingly expect sustainability claims to be supported by data, especially when it comes to Scope 3 emissions, which cover the indirect climate impact of purchased products and services.

To prove that their work was truly circular and minimize reputational risk, PJCE needed transparent, science-based documentation of how remanufacturing reduces emissions across the value chain. This became especially important as frameworks like the EU Taxonomy raise the bar for defining what truly qualifies as a circular or climate-aligned economic activity.

The Gap Between Practice and Proof

While PJCE’s remanufacturing practices clearly reduce material use and waste, the company had no standardized way to quantify carbon savings. Without verified data, it was difficult to:

  • Justify their use of the term circular in the new company name
  • Demonstrate Scope 3 emissions reductions to customers
  • Strengthen their position in a market that increasingly demands climate accountability

Verified Climate Assessments with ReFlow

To address this challenge, PJ Circular Engineering partnered with ReFlow to turn its green claims into verified, measurable insights:

  • Conducted Product Carbon Footprint (PCF) analyses for key remanufactured components using cradle-to-cradle methodology.
  • Compared the carbon impact of remanufacturing vs. producing new units across realistic vessel lifespans.
  • Built digital models of components in the ReFlow platform and validated data with ReFlow’s LCA specialists.
  • Ensured compliance with the GHG (greenhouse gas) Protocol and CSRD (Corporate Sustainability Reporting Directive) and emerging expectations under the EU Taxonomy for sustianble activites.
  • Provided customers with clear Scope 3 emission savings data for reporting and procurement decisions.

Results: Significant Carbon Savings Across Maritime Components

ReFlow’s climate assessments revealed the substantial carbon savings of PJCE’s remanufacturing solutions:

  • Turbocharger (Axial Type): Over a 20-year vessel lifespan, remanufacturing cuts carbon emissions by over 80%, saving 465,000+ kg CO₂e compared to new units.
  • Turbocharger (Radial Type): Remanufacturing reduces emissions by nearly 80%, saving 3,584 kg CO₂e over 20 years.
  • Governor: Extending the governor’s life cuts emissions by nearly 60%, avoiding 464 kg CO₂e over 20 years.
  • Cylinder Head / Cover Type: Remanufacturing achieves nearly 84% carbon footprint reduction, avoiding 6,461 kg CO₂e across a vessel’s 30-year lifespan.

These results gave PJCE the documented evidence they needed to substantiate their name change and strengthen their position as a credible circular supplier.

"We have since 1979 worked with circular repair methods without being able to document the savings in emissions. Since we joined the ReFlow platform in 2021, we have become data-driven with our emissions, resulting in increased competitiveness. We are very pleased with the easy-to-use and scientific platform and the high level of service from ReFlow. We would like to recommend this solution to our customers and suppliers anytime." - Anders Bruun, General Manager, PJ Circular Engineering A/S

Circularity Backed by Data

PJ Circular Engineering’s name change was more than symbolic, it was a statement of responsibility. By partnering with ReFlow, PJCE now has the verified carbon data to live up to that name, validate their circular practices, and reduce risk when communicating sustainability claims.

Their story shows how manufacturers can not only improve their climate impact but prove it.
