Environmental Applications of Microorganisms

376
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Design Example: Sustainability in Concrete Building

238
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...

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.

Electrical Energy01:10

Electrical Energy

1.3K
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules.

Healthcare Associated Infections II: Preventive Measures

3.1K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Bioremediation00:46

Bioremediation

20.7K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Area of Science:

  • Environmental Science
  • Public Health
  • Waste Management

Background:

  • Electronic waste (e-waste) represents the world's fastest-growing waste stream, posing significant environmental and health risks.
  • Increasing e-waste production drives substantial export from developed to developing nations, often undocumented.
  • Despite global recognition and policy efforts, a large fraction of e-waste remains unmanaged, accumulating in open dumpsites, particularly in Africa.

Purpose of the Study:

  • To estimate the total volume of e-waste in Africa for 2019, encompassing both locally produced and imported waste.
  • To identify the primary African recipient countries of e-waste and highlight nations of particular concern.
  • To underscore the need for improved waste management, regulatory frameworks, and enforcement to mitigate environmental contamination and human exposure.

Main Methods:

  • Utilized available data to calculate the total e-waste in Africa for 2019.
  • Acknowledged data limitations, including undocumented waste and discrepancies in reporting between formal and informal importers.
  • Identified key recipient countries based on available import and production data.

Main Results:

  • Estimated total e-waste in Africa for 2019 ranged between 3.4 and 5.8 metric tonnes (Mt), likely an underestimate due to data gaps.
  • Nigeria, Ghana, and Tanzania were identified as the main recipients of e-waste.
  • Kenya, Senegal, and Egypt were highlighted as countries of concern regarding e-waste accumulation.

Conclusions:

  • The current data on e-waste in Africa is incomplete, hindering precise estimations and effective management.
  • Inadequate waste management in recipient countries leads to severe environmental contamination and human health risks.
  • A coordinated regional and global approach, including strengthened regulatory frameworks and enforcement, is crucial for addressing the e-waste crisis.
