How Prismo Cut EPD Timelines in Half with KarbonWise

Challenge

Accelerating EPDs for market compliance

Prismo is a market leader in paints and coatings, primarily serving the road marking industry. The company’s products focus on road safety and include road markings for highways, surface coatings for car parks, pedestrian crossings and EV charging bays, high friction surfacing systems that improve braking performance and are also used on airport taxiways and runways, and bituminous products such as asphaltic plug joints and sealants for asphalt roads.

In short, Prismo creates “everyday surfaces that need to last.”

Although the company had previously completed EPD calculations, the earlier process was slow. As Gavin, Technical Director at Prismo, explained, “The last time we calculated EPDs, the process was quite long-winded. It took a long time.”

With new Danish regulations requiring EPDs for thermoplastic road marking tenders, Prismo needed a faster, more flexible system it could manage internally to meet tight submission deadlines.

“We needed to process a lot more products and find a system that we could run ourselves.” - Gavin, Technical Director

Solution

Partnering with KarbonWise for expertise and pace

The collaboration began when Gavin was contacted by KarbonWise. The first project focused on preparing EPDs for two thermoplastic road marking products for the Danish market.

From the outset, KarbonWise provided structured guidance and proactive support across every stage of the process. The team managed full cradle-to-gate calculations, environmental impact assessments, and the creation of the draft EPDs.

“It was a real pleasure to work with KarbonWise. The team are very knowledgeable. They understand the software, the subject, everything. They’re experts.” - Gavin, Technical Director

Consistent guidance throughout

The KarbonWise team not only led the technical process but also maintained constant communication. As Gavin noted, “They guided us through the calculation, even checking in regularly to see if I needed more support. I didn’t have to chase them.”

Overcoming the Verification Challenge

Once the calculations were complete, the third-party verification stage became a bottleneck. The external verifier was slow to respond, delaying progress.

Even then, KarbonWise remained involved, using the network to expedite communication and push the process forward. Gavin credited KarbonWise for “chasing and pushing them a lot” to ensure the verification was completed on time.

“KarbonWise stayed on top of the verification process right until it was signed off. Their persistence made a big difference.” - Gavin, Technical Director

  Gavin described the experience as “second to none,” noting the balance of deep expertise, proactive communication, and practical software usability

“They’re the real experts in their subject. I’ve learned a lot from working with them and they’ve been very supportive every step of the way.” - Gavin, Technical Director, Prismo

Summary

By partnering with KarbonWise, Prismo delivered verified Environmental Product Declarations for two thermoplastic road marking products in record time, meeting urgent Danish regulatory needs. The KarbonWise team combined expert calculation support, cradle-to-gate analysis, and hands-on verification management to ensure a smooth process from start to finish. The collaboration not only improved efficiency but also built in-house knowledge, enabling Prismo to scale its EPD work across future products with confidence.
