E meter analog w mix

Divided into common mechanical meters (analog) and modern electronic meters (digital). Additionally, classification can be based on the external material (e.g., shell-less, plastic shell, glass shell, etc.).

Recycling of old electric meters typically involves the following channels:
1. Public utilities: Many power companies regularly replace old meters, including upgrades to smart meters, resulting in a large number of discarded meters. These companies usually have their own recycling plans or collaborate with professional recycling companies to handle these waste meters.
2. Waste recycling centers: Some waste recycling centers or waste disposal plants accept old meters and disassemble them to recover metals and other valuable materials. Residents or businesses can directly deliver old meters to these recycling centers.
3. Professional e-waste recycling companies: These companies specialize in the recycling of electronic products, including waste meters. They typically possess professional equipment and qualifications for handling electronic waste, enabling them to safely disassemble meters and recover valuable materials.
4. Building demolition or renovation sites: During building demolition or renovation, a large number of meters are discarded, often with similar specifications and quality, making them suitable for recycling and processing.
5. Commercial and industrial sites: Some commercial or industrial facilities produce waste meters during upgrades or maintenance of their electrical infrastructure. These facilities usually collaborate with waste recycling companies to ensure proper handling of these discarded materials.

Valuable materials in waste electronic meters include:
* Metals: Copper (enamel-coated wires and copper wires), aluminum (used in some structural components), and steel (used in shells and structural components).
* Plastics: Shells and internal insulation components may be made of various plastics, which can be recycled and reused.
* Electronic components: In electronic meters, circuit boards contain various components, including low-grade circuit boards. These may contain silver, gold, palladium, and other precious metals, as well as copper and other recyclable metals.

Meters, as miscellaneous goods, require disassembly to become valuable metal waste. The disassembly process mainly involves manual disassembly and mechanical disassembly. Manual disassembly involves opening the shell, removing valuable metal components and electronic components, and categorizing them. Mechanical disassembly involves crushing the meter and then separating the shell (stainless steel, aluminum) and internal structural components, circuit boards, etc.

Meter waste is typically classified through trial disassembly.

Meters are mainly disassembled manually, suitable for areas with low labor costs. Disassembled materials include copper and circuit boards. Thailand and Malaysia have good copper prices, making them suitable destinations for selling meter waste to disassembly factories.

When trading meter waste, it is essential to ensure the consistency of the reported photos and actual goods, as well as the consistency of the reported location and actual shipment location. This is because meter waste has a high degree of variability, and prices heavily depend on information such as images and origin.
