Summary
Scientific research on waste management shows a shift from incineration towards valorisation. Creating a circular economy requires prioritizing waste prevention, reuse, and recovery over elimination.
Area of Science:
- Environmental Science
- Waste Management Research
- Circular Economy Studies
Background:
- Global waste management presents significant challenges.
- Understanding research evolution is crucial for future strategies.
- Identifying key future issues in waste recovery is essential.
Purpose of the Study:
- To analyze the evolution of scientific research in waste management.
- To identify emerging trends and future challenges, particularly in waste recovery.
- To map the scientific landscape of waste management research.
Main Methods:
- Longitudinal bibliometric analysis.
- Scientific mapping using strategic maps.
- Thematic network analysis.
Main Results:
- The concept of incineration is declining due to social opposition.
- Valorisation is emerging as a broader, more encompassing concept.
- Research trends indicate a move towards circular economy principles.
Conclusions:
- Policy makers should aim for a zero-waste circular economy.
- Adherence to the waste hierarchy (prevention, minimization, reuse, valorisation, recovery, elimination) is critical.
- Future waste management strategies must integrate valorisation and circularity.

445
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...

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.

01:10Volatilization
613
Volatilization gravimetry is an analytical technique that measures the mass lost due to the volatilization of the substance. This technique is used to estimate the amount of volatile material in a sample. To perform this method, heat a known amount of the sample to a high temperature in a crucible or other suitable vessel. The volatile substance in the sample evaporates, and the vapor is completely expelled from the crucible either by heating the sample or bubbling a stream of inert gas through...
