E meteres digital no cover

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.)

The recycling of discarded electric meters typically involves the following channels:
1. Public utility companies: Many power companies regularly replace old meters, including upgrading to smart meters, which generates a large number of discarded meters. These companies usually have their own recycling plans or cooperate with professional recycling companies to handle these discarded meters.
2. Waste recycling centers: Some waste recycling centers or waste disposal plants accept discarded meters and dismantle them to recover metals and other valuable materials. Residents or businesses can directly deliver discarded meters to these recycling centers.
3. Professional e-waste recycling companies: These companies specialize in the recycling of electronic products, including discarded meters. They usually have professional equipment and qualifications for handling electronic waste, allowing them to safely dismantle meters and recover valuable materials.
4. Construction demolition or renovation sites: Building demolitions or renovations often discard a large number of meters, usually of similar specifications and quality, making them convenient for recycling and processing.
5. Commercial and industrial establishments: Some commercial or industrial facilities also generate discarded meters during upgrades or maintenance of their electrical infrastructure. These facilities usually cooperate with waste recycling companies to ensure proper handling of these discarded materials.

Valuable materials in discarded electronic meters include:
- Metals: Copper (enamel-coated wires and copper wires), aluminum (used in some structural components), and steel (used in the shell and structural components).
- Plastics: The shell 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 valuable components, belonging to low-grade circuit boards. These may contain silver, gold, palladium, and other precious metals, as well as copper and other recyclable metals.

Electric meters, as mixed goods, require dismantling before becoming valuable metal waste. The dismantling process mainly involves manual and mechanical dismantling. Manual dismantling involves opening the shell, removing internal valuable metal components and electronic components, and classifying them. Mechanical dismantling involves crushing the meter and then separating the shell (stainless steel, aluminum) and internal structural components, circuit boards, etc. through sorting.

Discarded meter waste is typically detected through trial dismantling and classification.

Electric meters are primarily dismantled manually, making them suitable for dismantling in areas with lower labor costs. The dismantled materials include copper and circuit boards, which are in high demand in countries like Thailand and Malaysia with good copper prices. Therefore, discarded meter waste is suitable for sale to dismantling factories in Thailand and Malaysia.

When trading discarded meter waste, it is essential to pay attention to the consistency between the reported photos and actual goods, as well as the consistency between the reported location and actual shipping location. This is because discarded meter waste has a high degree of variability, and prices are heavily dependent on information such as images and origin.
