Segment 2: Case Study Analysis (30 min)
NOx Emissions from Ships
Hong Kong was the first in Asia to mandate low-sulfur fuel for ocean-going vessels at berth. This initiative has significantly reduced maritime emissions in the port area.
Prompt:
Evaluate whether this strategy would work in a rural vs. urban setting. Consider the infrastructure requirements and economic implications.
Blue Ocean Policy
A comprehensive policy framework aimed at improving coastal water quality through enhanced sewage treatment, marine debris management, and ecosystem restoration.
Prompt:
Evaluate whether this strategy would work in a rural vs. urban setting. What are the key differences in implementation challenges?
Food Waste/Sewage Recycling Facility
Hong Kong's first food waste-to-energy facility converts organic waste into biogas for electricity generation while producing nutrient-rich compost.
Prompt:
Evaluate whether this strategy would work in a rural vs. urban setting. Consider scalability and community engagement factors.
Segment 3: Design Challenge (10 min)
Activity: Work in pairs to draft a 3-step action plan to reduce waste in a Hong Kong residential complex.
Design Challenge Guidelines
- •Consider waste separation strategies
- •Think about community engagement
- •Explore partnerships with local businesses
