Summary
University students generate significant electronic waste, offering a valuable source of secondary metals. Exploiting this potential through improved collection could yield millions and support a circular economy.
Area of Science:
- Materials Science
- Environmental Science
- Circular Economy Studies
Background:
- Growing concerns about future scarcity of primary ferrous and non-ferrous materials.
- High ownership of Electrical and Electronic Equipment (EEE) in developed nations presents a source of secondary materials.
- University campuses, with high EEE consumption by young people, represent a potential resource for urban mining.
Purpose of the Study:
- To evaluate Small Household Appliances (SHA) as Distinct Urban Mines (DUM) within a UK university.
- To quantify student ownership, recycling, stockpiling, and discarding habits of SHA.
- To assess the monetary potential of SHA DUM at a UK level and propose exploitation methods for universities.
Main Methods:
- Quantitative survey to determine student SHA ownership and discarding behaviors.
- Estimation of ferrous and non-ferrous materials from discarded and stockpiled SHA.
- Conversion of material quantities to monetary values using secondary materials market data.
Main Results:
- 35% of SHA are discarded in general refuse, with broken personal care appliances frequently discarded due to hygiene and size.
- Working SHA are equally reused, recycled, or stockpiled by students.
- The University of Southampton has 189 tonnes of ferrous and non-ferrous materials available in discarded or stockpiled SHA.
Conclusions:
- Discarded and stockpiled SHA in UK higher education represent a potential value of approximately USD 11 million.
- Universities can contribute to a circular economy by exploiting SHA DUM.
- Improving user choice architecture with specific collection methods for broken SHA is recommended for DUM exploitation in higher education.

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...

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
