Optimizing municipal solid waste management in industrial ports: A case study of source separation implementation.

With the acceleration of industrialization and population growth, there has been a notable surge in municipal solid waste (MSW) production globally. This necessitates the development of efficient waste management strategies that align with sustainable economic, environmental, and social goals. Implementing sorting and source separation policies serves as foundational steps toward optimizing material flow and resource utilization.

An ISM approach to overcome the participation barriers in the waste source separation-a case study: Urmia University Campus.

A procedure developed to identify and facilitate the implementation of waste source separation strategies applicable in higher education centers, as a prerequisite for the expansion of recycling programs. The target materials proper to be separated were selected based on quantitative/qualitative analysis of waste produced on the Nazlou Campus of Urmia University, Iran (as a case study). The barriers to implementation of the program were identified using the interpretive structural modeling (ISM) methodology.

Landfill Leachate Treatment Through Coagulation-flocculation with Lime and Bio-sorption by Walnut-shell.

Due to the environmental consequences corresponding to leachate penetration, a sequence of inexpensive conventional processes proposed leachate treatment. The main objective was maximizing the COD and heavy metal removal efficiencies while minimizing generated sludge volume and material consumption rate. Walnut-shell adsorption complements lime treatment by eliminating heavy metals and low molecular-weight organic compounds.

Energy consumption and relative efficiency improvement of Photo-Fenton - Optimization by RSM for landfill leachate treatment, a case study.

The main objective of this study is to investigate the application of Photo-Fenton process to treat landfill leachate with minimum energy consumption and maximum COD removal efficiencies, simultaneously. Accordingly, an operational assessment of Photo-Fenton process was conducted in terms of variables, namely oxidation pH, [HO]/[Fe] molar ratio, and Fe dosage. The Central Composite Design (CCD) based on Response Surface Methodology (RSM) was applied for statistical analysis and optimization of target parameters.

Application of quadratic regression model for Fenton treatment of municipal landfill leachate.

The effectiveness of Fenton process in municipal landfill leachate treatment, as a pre- or post-treatment approach, has been demonstrated. However, no general recommendations of universal validity could be made in the term of optimized conditions affecting Fenton process. At the first stage of this study, collected leachate samples from Aradkooh site, Tehran, Iran, were investigated using one-factor-at-a-time method to find out optimum coagulation pH and flocculation time values.

Evaluation of the main parameters affecting the Fenton oxidation process in municipal landfill leachate treatment.

The aim of this study was to investigate the use of the Fenton oxidation process for treating leachate from a municipal solid waste landfill collected from Aradkooh site, Tehran, Iran. The focus of the study was to evaluate the process performance by COD removal efficiency. Results indicate that the optimum amounts of oxidation parameters in the Fenton process were as follows: oxidation pH = 4, H(2)O(2)/Fe(2+) molar ratio = 4-5, Fe(2+) ion dosage = 11,200-19,600 mg L(-1) and oxidation time = 20-30 min.
