Last week, at the SCALE pavillion by Spectrum Impact at Chemtech 2026, we saw something quietly powerful take shape.
Together with altM, our
#ACTForEnvironment portfolio startup, we convened researchers, innovators, and industry leaders around a simple but ambitious question: Can agri-waste derived lignin move from the margins of materials science to the mainstream of industrial manufacturing?
As one of the most abundant biopolymers on the planet, agri-waste derived lignin holds promise as an alternative to petrochemicals. But promise alone doesn’t build markets. Pathways do.
As we went around the room, the group surfaced some compelling insights:
1. Application-led research is the unlock: Feedstock variability continues to slow down R&D and standardisation. Anchoring research in specific industrial use cases (resins, rubbers, bioplastics) can shorten development cycles and make scale more achievable.
2. Industry adoption needs real-world proof, not just potential: Lignin-based materials are advancing, but price competitiveness and PMF remain barriers. What’s missing is shared performance data that allows industries to compare lignin-based solutions against fossil-based incumbents with confidence.
3. Agri-waste to value is a strategic opportunity: Agricultural residues and biogas digestate can be converted into high-value materials; improving unit economics while reducing dependence on fossil inputs. This is where climate logic and business logic begins to align.
4. Environmental impact depends on systems design: Lignin can displace petrochemicals, but challenges like sulphur content and processing efficiency must be addressed thoughtfully if sustainability gains are to hold at scale.
But the most important thing that we all agreed on was that collaboration in this space is not optional - it is infrastructural. Open data, shared learnings, and ecosystem-wide coordination are essential to bridge R&D gaps and accelerate industrial adoption.
Our collective hope with altM is that this conversation doesn't stop here.
And so, this roundtable also marked the soft launch of the Lignin Innovation Network Collective (LINC) - a platform to bring together innovators, researchers, industrial manufacturers and ecosystem enablers to co-create a roadmap for lignin’s industrial future - not in silos, but as a shared transition.
At ACT, we believe climate innovation succeeds when innovation is grounded in real markets, waste streams become economic inputs and ecosystems are built through shared infrastructure.
We’re excited to see altM spark this community and look forward to witnessing where this collective takes lignin next!
