Summary
This study examines "shadow stadia"—old sports venues left behind by new developments. It explores their environmental impacts and proposes circular economy strategies to extend their lifecycle and inform future urban planning.
Area of Science:
- Urban Planning
- Environmental Science
- Sports Management
Background:
- New stadium development often overlooks the fate of existing venues, termed "shadow stadia."
- Shadow stadia face varied outcomes: repurposing, demolition with delayed redevelopment, or abandonment.
- The environmental and neighborhood impacts of shadow stadia are poorly understood due to limited research.
Purpose of the Study:
- To analyze the academic literature on the circular economy in relation to sports facilities.
- To categorize global shadow stadia and identify opportunities for integrating circular economy principles.
- To highlight future research needs for sustainable urban and sports venue development.
Main Methods:
- Literature review of circular economy advancements.
- Global case study categorization of shadow stadia.
- Analysis of opportunities for circularity integration in sports facility management.
Main Results:
- Current research on shadow stadia and their environmental impact is limited.
- Circular economy principles offer potential solutions for extending the life of existing sports facilities.
- A framework for categorizing shadow stadia and integrating circularity is proposed.
Conclusions:
- Addressing the lifecycle of shadow stadia is crucial for sustainable urban development.
- Integrating circular economy strategies can mitigate negative environmental impacts and enhance community value.
- Further research is needed to guide cities and sports organizations in managing the transition to new facilities.

Design Example: Sustainability in Concrete Building
223
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Sustainable Development
13.5K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Steel Manufacturing
780
Steel manufacturing is a multi-stage process that begins by smelting iron ore into cast iron in a blast furnace. This initial stage involves layering iron ore with coke, a type of fuel, and crushed limestone within the furnace. The coke is ignited with a high volume of air, leading to the creation of carbon monoxide, which acts to reduce the iron ore to pure iron.
During this smelting process, limestone plays a crucial role by forming slag. Slag captures impurities within the molten iron, such...

Stereotype Content Model
14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

The Phosphorus Cycle
38.6K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

The Carbon Cycle
39.5K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
