Following the material trail across geopolitics, climate, circularity, and the industries shaping the future.
‘US President Trump is actively seeking the surrender or disposal of Iran’s enriched uranium stockpile, exploring pathways for Iran to either transfer the material out of the country or dilute it to avoid easing existing sanctions’.
The above news triggered my research and led me into the rabbit hole of the advanced materials industry.
I was trying to make sense of a series of seemingly unrelated headlines on war, supply chain disruptions, data centre establishments, gas price hikes, critical mineral shortages, and geopolitical tensions.
One article discussed critical minerals. Another focused on rare earth elements. A third covered geopolitical tensions and supply chain disruptions. Elsewhere, investors were talking about energy security, defence startups, battery manufacturing, semiconductors, and industrial sovereignty. In climate circles, conversations revolved around renewable energy, carbon removal, circularity, and industrial decarbonisation.
At first glance, these appeared to be separate conversations taking place in different rooms.
The Rabbit Hole Beneath the Headlines
The more I read, however, the more I realised that everyone was circling around the same issue: materials.
Not necessarily the kind that dominate headlines or conference stages, but the ones quietly sitting underneath them. The minerals inside batteries. The chemistry inside products. The polymers behind packaging. The compounds used in construction. The feedstocks powering manufacturing.
The further I dug, the clearer it became that materials are not merely another industry. They are the physical building blocks that underpin almost every industry we care about.
Like many rabbit holes, this one became impossible to ignore once I started connecting the dots.
What struck me most was not the scale of the opportunity. It was how familiar many of these conversations felt.
The Puzzle Pieces Were Already There
Over the last eight years, I have spent countless hours speaking with founders, judging startups alongside investors, attending climate events, talking to practitioners across different countries to understand local and global trends, sitting through accelerator showcases, participating in ecosystem conversations, and interviewing people building solutions across climate, sustainability, and impact.
At various points, I met founders turning waste plastic into polymers. Others were extracting critical minerals from battery waste. Some were transforming discarded plastic bottles into textiles. Others were experimenting with algae, seaweed, microbial systems, bamboo, agricultural residues, and mycelium.
There were people developing low-carbon cement, carbon-capturing construction materials, biochar composites, recycled polymers, sustainable dyes, alternative packaging materials, next-generation battery technologies, advanced water treatment systems, and a growing range of bio-based and regenerative materials.
At the time, I viewed each of these innovations through the lens of the problem they were trying to solve. Some belonged to waste management. Others sat within construction, energy, agriculture, packaging, textiles, water, or manufacturing. Each startup appeared to occupy its own niche, serving its own market and addressing its own challenge.
Only recently did I realise I had been looking at fragments of a much larger story.
The story was never about the individual industries. It was about the materials moving through them.
That distinction may seem subtle, but it changes everything.
When Everyone Is Looking at Different Pieces of the Elephant
One of the recurring frustrations I encounter in climate and sustainability conversations is how fragmented they have become.
- Climate professionals often discuss emissions.
- Sustainability professionals discuss ESG.
- Investors discuss sectors.
- Policymakers discuss regulations.
- Startups discuss products.
- Activists discuss justice.
- Educators discuss awareness.
All of these conversations are important. Yet they frequently happen in parallel rather than in conversation with one another.
As a result, many people entering the space feel overwhelmed.
- Students do not know where they fit.
- Professionals struggle to identify transition pathways.
- Investors struggle to separate credibility, validation, and long-term value from noise and hype.
- Founders struggle to understand adjacent opportunities, benchmark themselves globally, or identify opportunities to pivot and expand.
- Even experienced practitioners can find themselves trapped within their own disciplinary silos.
The more I explored advanced materials, the more I realised that the industry offered a surprisingly useful lens for understanding these intersections.
Looking Beneath the Product
A battery is not simply an energy or mobility story.
- It is also a mining story, a manufacturing story, a chemistry story, a recycling story, a geopolitical story, a supply chain story, and increasingly, a circular economy story.
- A solar panel is not merely a renewable energy product.
- It is also a materials challenge involving silicon, rare minerals, manufacturing capabilities, recycling systems, trade policies, and resource security.
- A data centre is not simply digital infrastructure.
- It is also a story about semiconductors, cooling systems, advanced materials, energy systems, water use, and supply chains.
Even the climate transition itself cannot be reduced to a single narrative.
Climate Change Is Also a Materials Problem
For years, climate change has largely been framed as an energy problem or a fossil fuel problem.Energy is undoubtedly central to the challenge. Yet the deeper I go into this work, the harder it becomes to view climate change solely through an energy lens.
Climate change is also a materials problem.
- It is a manufacturing problem.
- It is a consumption problem.
- It is a design problem.
- It is a systems problem.
And perhaps most importantly, it is a relationship problem.
- A relationship between extraction and regeneration.
- Between use and abuse.
- Between efficiency and sufficiency.
- Between growth and ecological limits.
Human civilisation has always depended on extracting resources from the natural world. The issue is not extraction itself. The issue is whether we can learn to operate within ecological boundaries while ensuring that future generations inherit functioning ecosystems rather than depleted ones.
That question becomes increasingly relevant as countries race to secure critical minerals, expand manufacturing capabilities, build energy infrastructure, and compete for strategic advantage.
The current geopolitical landscape reflects this tension perfectly.
Governments are investing heavily in domestic manufacturing. Nations are competing for access to strategic resources. Supply chains are being redesigned. Industrial policies are being rewritten. Investors are searching for opportunities in sectors that barely existed a decade ago.
At the same time, a parallel movement is emerging.
- Founders are experimenting with materials that capture carbon instead of releasing it.
- Researchers are designing alternatives to resource-intensive materials.
- Manufacturers are finding ways to transform waste streams into feedstocks.
- Engineers are recovering minerals from products that previously ended up in landfills.
- Biologists are turning living systems into manufacturing platforms.
- Designers are exploring products built for repair, disassembly, reuse, and regeneration.
Viewed together, however, they begin to resemble the foundations of a new industrial paradigm—one where waste becomes feedstock, carbon becomes a resource, biology becomes a manufacturing platform, and material circularity becomes a competitive advantage rather than a sustainability initiative.
The Taxonomy That Refused to Stay Small
That realisation led me to an exercise that was originally intended to be simple.
I decided to map the advanced materials ecosystem.
What I assumed would be a relatively straightforward categorisation exercise quickly turned into one of the most complex industry-mapping exercises I have undertaken. I am currently working through more than 150 sectors, subsectors, and intersecting domains, and every attempt to simplify the landscape seems to reveal another layer beneath it.
- Construction materials led to carbon-negative materials.
- Carbon-negative materials led to bio-based materials.
- Bio-based materials led to regenerative materials.
- Regenerative materials led to living materials.
- Living materials led to biomimicry.
Critical minerals connected to batteries, manufacturing, defence, electronics, mobility, and energy systems. Circular materials connected to product design, waste management, industrial symbiosis, and material intelligence.
The map kept expanding because the real world refuses to fit neatly inside categories.
By the time I stepped back from the exercise, I was looking at a landscape that stretched across low-carbon construction, circular materials, regenerative materials, critical minerals, advanced chemistry, sustainable textiles, carbon removal materials, energy materials, water materials, smart materials, water filtration materials, frontier materials, and material intelligence systems.
The taxonomy was useful.
But the exercise itself was even more valuable.
More importantly, it exposed a blind spot I increasingly see across climate, sustainability, startup, and investment circles. We often discuss technologies, products, and sectors, but rarely the material systems that connect them. Yet those material systems frequently determine whether an innovation can scale, whether supply chains remain resilient, and whether a climate solution can move from prototype to widespread adoption.
It reminded me how much complexity sits beneath the surface of the climate transition.
The Future Emerges at the Intersections
Many of the opportunities shaping the next few decades are emerging at the intersections between industries rather than within them.
The founder working on biochar may be contributing to agriculture, carbon removal, manufacturing, construction, and soil restoration simultaneously.
The startup recovering critical minerals from batteries may be operating within recycling, mining, energy security, defence, and circular economy conversations at the same time.
The company developing algae-based materials may be touching biotechnology, food systems, pharmaceuticals, manufacturing, packaging, consumer goods, and carbon management all at once.
The future rarely respects our categories.
It tends to emerge between them.

Beyond Climate Tech, Toward Systems Thinking
Perhaps that is why I find myself increasingly drawn toward systems thinking.
Systems thinking forces us to zoom out.
It encourages us to ask uncomfortable questions.
- If carbon can become a feedstock, a construction material, a polymer, an industrial input, or even a source of value, should we continue thinking about it exclusively as waste?
- If waste can become a resource, should disposal remain our default approach?
- If critical minerals can be recovered from batteries, electronics, industrial by-products, and urban infrastructure, how much of the resource challenge is actually a recovery challenge rather than an extraction challenge?
- If biology can help manufacture materials, what happens to traditional industrial models?
And if climate change is simultaneously an energy problem, a materials problem, a consumption problem, and a systems-design problem, why do we continue treating these conversations as separate disciplines?
I do not claim to have the answers.
In many ways, this taxonomy emerged because I was trying to organise my own confusion. The more I map these industries, the more I realise how much there is left to learn. Yet that uncertainty is precisely what makes this space so fascinating.
Mapping the Industries Beneath the Industries
We are witnessing the early formation of industries that could reshape manufacturing, supply chains, resource management, climate action, and economic development over the coming decades.
Some of these industries already have names. Many do not. Some will succeed. Others will fail.
What interests me most is not predicting the winners. It is understanding the systems that make those outcomes possible.
The more time I spend mapping emerging industries, the less interested I become in sectors and the more interested I become in systems.
Industries are useful categories. Systems are where reality lives.
Climate, sustainability, manufacturing, energy, defence, AI infrastructure, critical minerals, circularity, regeneration, and advanced materials are often discussed as separate conversations. Increasingly, I am convinced they are all chapters of the same story.
The challenge is not simply understanding the industries themselves but it is learning to see the connections between them before everyone else does.
If you are a founder, investor, family office, corporate venture capital leader, policymaker, researcher, foundation, ecosystem builder, or professional navigating these transitions, I would love to hear what patterns you are seeing.
Over the coming months, I will continue mapping emerging industries, frontier technologies, climate solutions, regenerative systems, and the often-overlooked intersections that connect them.
Because the industries shaping the future rarely emerge in isolation.
They emerge where disciplines collide.
