Summary
Municipal solid waste management (MSWM) efficiency in China is generally low, with significant regional disparities. Improving MSWM requires tailored policies, as current approaches show limited impact, especially concerning waste classification.
Area of Science:
- Environmental Science
- Public Health
- Urban Planning
Background:
- Municipal solid waste (MSW) mismanagement poses significant public health risks globally.
- Effective municipal solid waste management (MSWM) is crucial for urban sustainability.
- China's government has implemented policies to enhance MSWM, yet efficiency studies remain scarce.
Purpose of the Study:
- To comprehensively analyze MSWM efficiency in China.
- To identify high-efficiency policy implementation routes for MSWM.
- To find breakthroughs for improving MSWM efficiency.
Main Methods:
- Introduction of the three-stage data envelopment analysis (DEA) model for accurate MSWM efficiency measurement.
- Application of the Fuzzy c-Means algorithm for cluster analysis of 33 typical Chinese cities.
- Elimination of external environmental and random interference factors.
Main Results:
- Overall MSWM efficiency declined from 0.575 to 0.544 after adjustments.
- Mean pure technical efficiency (PTE) decreased significantly from 0.966 to 0.611.
- Mean scale efficiency (SE) increased substantially from 0.600 to 0.907, with notable regional variations.
Conclusions:
- MSWM efficiency in China is low and requires improvement, with significant regional differences observed.
- Central and northeastern regions show lower PTE, while western regions exhibit higher SE.
- While MSW classification pilot programs show affirmative results, differential management strategies for various city types are recommended for enhanced MSWM efficiency.

02:22Structures of Solids
17.7K
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...

02:37Metallic Solids
20.6K
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.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

16.2K
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...

02:54Molecular and Ionic Solids
20.1K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

02:26Molecular Comparison of Gases, Liquids, and Solids
55.1K
Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...

01:01Energy Bands in Solids
2.0K
Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...
