Summary
A new model optimizes municipal solid waste (MSW) management by accurately predicting waste generation and system dynamics. This approach enhances planning for Beijing
Area of Science:
- Environmental Engineering
- Operations Research
- Data Science
Background:
- Municipal solid waste (MSW) management faces challenges due to increasing generation rates and system uncertainties.
- Accurate prediction and optimization are crucial for effective MSW planning in urban areas.
Purpose of the Study:
- To develop a novel two-stage support-vector-regression optimization model (TSOM) for enhancing MSW management planning.
- To improve the accuracy of predicting future waste generation and understanding system dynamics.
Main Methods:
- Coupling a support-vector-regression (SVR) model with interval-parameter mixed integer linear programming (IMILP).
- Evaluating four kernel functions (linear, polynomial, RBF, MLP) using prediction accuracy (PA), fitting accuracy (FA), and overall accuracy (OA).
- Analyzing two distinct waste management policy scenarios.
Main Results:
- The SVR model with a polynomial kernel achieved over 96% accuracy in predicting MSW generation rates.
- The TSOM effectively captured the dynamic, interactive, and uncertain characteristics of MSW management.
- Simulation results provide valuable insights for waste allocation and capacity planning.
Conclusions:
- The TSOM offers a robust framework for optimizing MSW management systems.
- Findings support policy adjustments to increase waste diversion rates and meet treatment demands.
- This model enhances decision-making for sustainable urban waste management.

Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...

Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
