This transition demonstrates how material innovation can support both environmental responsibility and business performance.

Lower CO₂ footprint through material reduction 
Replacing heavy glass jars with lightweight DuoSmart™ PP pots substantially reduces material weight across the packaging lifecycle. The benefits include:

• Reduced CO₂ emissions associated with raw material extraction and processing
• Lower energy demand during production and transportation
• Maintained product protection and quality

This weight reduction forms the foundation of the environmental gains achieved through the transition.

Major logistics efficiency improvements 
Transport optimisation emerged as one of the most impactful outcomes of the material switch. Switching from glass jars to DuoSmart™ PP pots increases transport efficiency by over 330%, meaning glass requires more than four times the number of truckloads to move the same amount of product. 

This scaled impact includes:

• Fewer trucks on the road
• Lower transport related emissions per delivered unit
• Reduced fuel and logistics costs
• More efficient downstream distribution with higher quantities available per load

This is a clear example of how the right packaging directly enhances operational efficiency.

Improved durability, reduced waste 
The transition away from fragile glass eliminates breakage risks during handling, storage, and transport. Benefits include:

• Less product loss due to breakage
• Enhanced safety for supply chain teams
• More finished goods arriving on shelves intact

For high volume everyday items like jams and cucumber salads, durability translates into meaningful waste reduction throughout the value chain.

Results of transition 
Herkkumaa’s shift from glass to DuoSmart™ PP demonstrates how packaging optimisation can deliver measurable results across the value chain. Reduced packaging weight, improved transport efficiency, and lower breakage together contribute to lower emissions and a more efficient supply chain.
