Circular Bioeconomy
“Circular economy as an industrial economy that is restorative or regenerative by value and design”
– How the Ellen MacArthur Foundation defines the circular economy
1
Carbon Absorption – Teaming Up with Photosynthesis
Nature lays the foundation for PaperShell’s circular system. Through photosynthesis, trees absorb CO₂ from the atmosphere, converting it into biomass. This natural carbon capture process reduces greenhouse gases while supporting ecosystems. PaperShell aims that this captured carbon remains stored in long-lasting materials, preventing it from re-entering the atmosphere.
2
Residue Transformation – Upcycling Industrial Byproducts
PaperShell’s raw material utilises residues from the forest and packaging industries — wood chips, sawdust, and offcuts that would otherwise be turned into short-lived products or waste. These residues are refined into kraft paper pulp, keeping valuable resources in circulation.
3
PaperShell Kraft Paper – Impregnated with Biobinder
The kraft paper pulp is further processed into kraft paper rolls, forming the base material for PaperShell’s production. At this stage, the paper is pre-impregnated with our proprietary biobinder, ensuring a 100% biogenic composition.
4
Paper In – Product Out
This pre-impregnated kraft paper serves as the raw input material for PaperShell’s fully automated production lines. The kraft paper is cut, stacked and compressed under heat and pressure, transforming it into 100% biogenic components without compromising on strength and durability.
5
Use and Reuse Phase
PaperShell components enter their intended applications, replacing fossil-based and carbon intensive materials across industries such as automotive, furniture, and architecture. Their durability and functional performance ensure a long lifespan, making them a viable ecological alternative for climate negative materials.
6
Closing the Loop – Biochar conversion
At the end of their lifecycle, PaperShell components can transformed into biochar through pyrolysis – a thermal decomposition process that breaks down organic materials at high temperatures in an oxygen-limited environment. This effectively locking the carbon content of PaperShell components into high quality biochar.
7
Return to Life – Enhancing Soil Health
This biochar produced from PaperShell components becomes a valuable soil enhancer, improving water retention, nutrient availability, and microbial activity. It becomes a hotel for beneficial microbes and mycelium. When integrated into agricultural or forestry soils, it can support plant growth, enhance biodiversity, and increase long-term carbon storage, contributing to healthier, more resilient ecosystems.
