Summary
This review analyzes 40 sets of municipal solid waste management indicators, identifying challenges in standardization. A new framework and a comprehensive list of 377 indicators are proposed for better global application.
Area of Science:
- Environmental Science
- Waste Management
Background:
- Municipal solid waste management evaluation has relied on indicators for decades.
- Existing indicator sets face challenges like data scarcity, lack of transparency, and homogeneity, hindering global standardization.
Purpose of the Study:
- To review and analyze existing municipal solid waste management indicators.
- To propose a new framework for integrated sustainable waste management indicators.
- To develop a standardized list of indicators for global application.
Main Methods:
- Documented and analyzed 40 sets of waste management indicators, assessing characteristics, strengths, and weaknesses.
- Classified indicators based on a new integrated sustainable waste management framework.
- Compared and consolidated indicators to create a single, comprehensive list.
Main Results:
- Identified 377 distinct indicators, with 49.3% focusing on technical aspects.
- The 'recovery' component (recycling, composting, incineration with energy recovery) had the most indicators.
- Found that indicator sets vary in type (qualitative, quantitative) and applicability level (municipal to international).
Conclusions:
- Standardization requires indicators useful across diverse geographical and economic levels.
- Effective indicator sets must include varied types, follow clear methodologies, and cover all relevant waste management aspects.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
