other factories as a heat source; fly ash from the coal-fired power plant is used as building
materials; and wastewater from the pharmaceutical factory is utilized for irrigating nearby
farmland.
② Cleaner Production Technologies: All resident enterprises have adopted advanced
cleaner production technologies, reducing energy and water consumption per unit output
while decreasing pollutant emissions. Additionally, the park actively promotes the applica-
tion of new energy sources, such as wind and solar power generation, further reducing reli-
ance on fossil fuels.
③ Community Engagement and Social Responsibility: The Kalundborg Eco-Industrial
Park places great emphasis on collaboration with local communities, regularly organizing
open-day events where residents are invited to tour and learn about the park’s operations.
Meanwhile, enterprises within the park actively participate in public welfare activities, fulfill
social responsibilities, and enhance their corporate image and reputation.
(3) Outcomes
The successful experience of the Kalundborg Eco-Industrial Park demonstrates that
industrial symbiosis and resource recycling not only improve economic efficiency but also
significantly reduce environmental impacts. According to statistics, the park saves energy
equivalent to reducing approximately 240,000 tons of CO2 emissions annually. Simultane-
ously, through water resource recycling, millions of cubic meters of freshwater are conserved
each year. The KalundborgModelhas become a benchmark case in the global circular econo-
my field, garnering widespread attention and acclaim.

Carbon Capture, Utilization and Storage (CCUS)

Carbon Capture, Utilization and Storage (CCUS) technology demonstrates significant
potential in reducing industrial emissions. It not only captures carbon dioxide (CO ) from
2
power plants and industrial processes but also enables utilization through various methods or
permanent storage, effectively lowering greenhouse gas concentrations in the atmosphere.
(1) Working Principles of CCUS Technology
CCUS encompasses three main stages: carbon capture (Capture), carbon utilization
(Utilization), and carbon storage (Storage). Each stage employs specific technologies and
methodologies:
(1) Carbon capture: Capturing CO at emission sources constitutes the first stage. Com-
2
mon capture technologies include:
Post-combustion capture: Applicable to traditional energy facilities such as coal-fired
power plants, using chemical absorbents (e.g., amine solutions) to capture CO from flue gas.

（2）Pre-combustion capture: Processes fuel before it is converted into syngas, typical-
ly used in conjunction with coal gasification technology, allowing more efficient separation
of CO2.
（3）Oxy-fuel combustion: Increases the oxygen ratio during combustion, resulting in
