Dismantling Computers and Global Supply Chains
Six years ago, the speaker was invited to give a talk to 60 primary school students (9-10 year olds) during their science week. Initially unsure of what to present, he decided to have the children dismantle old computers from the 1990s. The activity, while chaotic, revealed the global nature of manufacturing.
Example: A graphics card taken from one of the computers had components manufactured in Taiwan (chip), Germany (memory chips), and Mexico (assembly).
This exercise demonstrated how a global supply chain could be mapped from a scene of "utter destruction," highlighting the interconnectedness of manufacturing processes across different countries. This experience inspired the speaker to write a book about manufacturing.
The Complexity of Simple Products: Toilet Roll
The speaker initially planned to start his book with the iPhone but realized a simpler product would be more effective in illustrating manufacturing complexity. He chose toilet roll.
Details: Even a simple product like toilet roll requires fibers from different regions: soft fibers from South America and strong fibers from Scandinavia. The trees take 40 years to grow. The wood is processed into pulp, transported across the sea, and then sprayed onto rollers.
This example demonstrates that even seemingly basic items have surprisingly complex and geographically dispersed supply chains.
Supply Networks for Complex Products: Cars and Airliners
The speaker contrasts the toilet roll with more complex products like cars (30,000 components) and airliners (3-6 million components).
Research: The speaker's colleague, Alexander Brinrop, created maps illustrating the intricate supply networks for cars and airliners. Each dot represents an organization, and each line represents the movement of materials.
These maps reveal the vast scale and complexity of modern manufacturing, with components sourced from numerous companies and factories worldwide.
The Shipping Container and Global Logistics
The speaker emphasizes the importance of the shipping container (69 years old) in enabling global trade.
Statistics: The port of Felixstowe handles 4 million shipping containers annually. Over 220 million containers are in transit globally each year.
The shipping container has facilitated the cheap and efficient transportation of goods, connecting factories and enabling complex global supply chains.
The Dark Side: Lack of Resilience and Environmental Damage
The speaker identifies two major problems with the current manufacturing system: lack of resilience and environmental damage.
Example: The Suez Canal blockage by a single container ship disrupted 10% of global trade for six days, illustrating the vulnerability of the system.
Environmental Impact: The transportation of goods generates significant pollution from diesel, kerosene, and petrol. Overproduction and waste exacerbate the problem.
Three Industrial Revolutions in Two Minutes
The speaker summarizes 250 years of industrial history:
- First Industrial Revolution: Interchangeable parts enabled mass production.
- Second Industrial Revolution: The assembly line (inspired by disassembly lines in abattoirs) increased production volume.
- Third Industrial Revolution: Automation, initially physical (robots) and now cognitive (AI), reduced dangerous and difficult jobs.
Three Reasons for Optimism
The speaker presents three reasons for optimism about the future of manufacturing:
- Innovation: Humans are adept at innovation, as demonstrated by the evolution of mobile phones from bulky devices in the 1980s to the smartphones of today.
- Example: The speaker shows a large 1980s mobile phone and contrasts it with modern smartphones.
- Breaking the Rules: Modern manufacturing, including 3D printing and AI, allows for both high volume and high variety, moving beyond the traditional trade-off.
- Example: Personalized medicine, such as cancer treatments where cells are extracted, reprogrammed, and re-injected, demonstrates personalized manufacturing.
- Zero-Waste Factories: Factories can be designed to eliminate waste by finding value in every input and byproduct.
- Example: A sugar beet processing factory transformed itself into a zero-waste facility, using byproducts for bioethanol production and heat/CO2 for ripening tomatoes (and later, medicinal cannabis).
Conclusion: Manufacturing a Better World
The speaker concludes with a call for a more sustainable and responsible approach to manufacturing. He believes that continued innovation, personalized manufacturing, and the development of zero-waste factories can lead to a better future.
Key Statements:
- "We have to manufacture things, we need things, we want things, that's not going to change frankly, perhaps we could have a bit less."
- "We want the factories to become the places that you want to have at the end of your road because the not only do they produce good products the byproducts of what they produce is valuable to the local community or to others."
The speaker expresses optimism based on the awareness and enthusiasm of the younger generation, who are increasingly interested in secondhand goods and repairing items. He believes that with their help, a better manufactured world is possible.
