PolyU ISE and RIAM seminar named “Development and Assessment of Circular
Economy” was held on 20th Mar 2024. Prof. Hwong-wen Ma (National
Taiwan University) was guest speaker. His talk content structure was vision,
principle, objective, strategy, goal, target and development of the circular
economy.
In the beginning, Prof. Ma introduced “Vision” model named doughnut
economics that the first circle is environmental ceiling and the second circle
is social foundation. Its’ principle included resource efficient and climate
neutral.
Then he explained the objective for resource and impact decoupling. The
strategy named “Resource as a lever” was discussed that an integrated approach
to managing energy, raw materials, environmental and financial resources on a
sustainable and efficient basis over the full cycles of goods and services.
This strategy implemented as sustainable resource management (consumption
and production) from green economy efficiency to risk management resilience.
And then the goal was “how much resource efficiency needed” that closed
the gap by 50% to 70%. The target is retaining value through three models and
they were “Circular Design”, “Optimal Use” and “Value Recovery”.
After that the business models were discussed from circular supplies to
resource recovery. Circular Economy defined “Being restorative and regenerative
by design, keeping products, components, and materials at their highest value
at all times, through system-wide innovation of materials, products, business
models and value chain.”
The evolution of the terms for circular economy was showed. I like the
spaceship earth economics that implied earth is a spaceship.
Finally, the global trend on production, consumption, waste and
secondary materials were mentioned. There were five directions included i)
Product as focus, ii) Regulation and investment as driver, iii) Standardization
as scalability promoter, iv) Digitalization as connecter, and v) Collaboration
as path.
The summary diagram was demonstrated those directions relationship.
For circular economy, data collection is significant. Thus,
digitalization and industry 4.0 are important technology to be employed.
Prof. Ma also stated the change role of EPD that more focused on resource
efficiency together with environmental impacts.
Lastly, he introduced some research tools on the integration of
assessment methods including product and material flow analysis, resource and
waste input-output analysis, multimedia environmental fate modeling and life
cycle assessment and risk assessment.
He demonstrated material flow analysis in Taiwan.
As well as, liking driving forces and consequences showed in Taiwan.
At the end, the broad agenda was introduced that included environment,
society and economy.
In Q&A session, more than 100 participants joined this seminar
online. I asked questions about i4.0 and economy as well as customer behavior
for purchasing environment friendly product.
