Circular Economy and Sustainability
|July 12, 2022
Summary
This study maps the circular economy (CE) research landscape, identifying key themes like sustainability, bioeconomy, and waste management. It highlights the growing focus on Industry 4.0 technologies within the CE domain.
Area of Science:
- Environmental Science
- Economics
- Business Management
Background:
- The circular economy (CE) offers a sustainable alternative to the linear economy's resource depletion.
- A growing body of literature necessitates a structured overview of the CE field.
- This study provides the first systematic examination of CE knowledge and diffusion.
Purpose of the Study:
- To comprehensively analyze the knowledge base and diffusion pathways within the circular economy domain.
- To map the evolutionary structure, identify hot topics, and outline future directions of CE research.
- To provide scholars with a clear understanding of the CE field's genealogy.
Main Methods:
- Analysis of a Web of Science dataset comprising 5431 articles published from 1970 to 2020.
- Application of keyword co-occurrence network analysis for comprehensive domain review.
- Utilisation of Main Path Analysis (MPA) to examine four distinct path types (forward, backward, global, key-route).
Main Results:
- Identified six primary research themes: CE and sustainability, bioeconomy, CE practices, lifecycle assessment and industrial symbiosis, construction activities, and waste management.
- Revealed a recent surge in research connecting Industry 4.0 technologies with circular economy principles.
- The MPA successfully depicted the genealogy of CE research, illustrating its historical development.
Conclusions:
- The study provides a foundational map of the circular economy research landscape.
- It highlights emerging trends, particularly the integration of Industry 4.0 technologies.
- This research serves as a guide for scholars navigating the evolving field of circular economy.

01:17Passive Diffusion: Overview and Kinetics
693
Passive diffusion is a critical process that allows small lipophilic drugs to cross the cell membrane along a concentration gradient. This mechanism's efficiency depends on four primary factors: the membrane's surface area, the drug's lipid-water partition coefficient, the concentration gradient, and the membrane's thickness.
When administered orally, drugs establish a substantial concentration gradient between the gastrointestinal (GI) lumen and the bloodstream, expediting...

02:06Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

01:15Theories of Dissolution: Diffusion Layer Model
897
Dissolution, the process by which drug particles dissolve in a solvent, is explained by the diffusion layer model, a theoretical framework that simulates the absorption of oral drugs and allows us to analyze experimental data.
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...

01:17Dynamics Of Circular Motion: Applications
8.0K
Suppose a car moves on flat ground and turns to the left. The centripetal force causing the car to turn in a circular path is due to friction between the tires and the road. For this, a minimum coefficient of friction is needed, or the car will move in a larger-radius curve and leave the roadway. Let's now consider banked curves, where the slope of the road helps in negotiating the curve. The greater the angle of the curve, the faster one can take the curve. It is common for race tracks for...

01:25Design Example: Flow of Oil Through Circular Pipes
181
Understanding fluid flow behavior through pipes is critical in fluid mechanics, especially in applications like oil transportation through pipelines. Hagen-Poiseuille's law provides an exact solution derived from the Navier-Stokes equations for steady, incompressible, and laminar flow within a circular pipe. Hagen-Poiseuille's law helps determine the necessary pressure drop across a pipeline section by determining parameters like pipe length, radius, oil viscosity, and the desired...
