Scrap Chip

The term "scrap chip" refers to two distinct industrial sectors: electronic integrated circuits (ICs) for precious metal recovery and metal machining shavings for foundry reuse. Both markets are currently driven by circular economy initiatives but differ significantly in value and processing.

1. Electronic Scrap Chips (Gold Recovery)

This market focuses on extracting gold, silver, and palladium from obsolete electronics.

* Market Trends: There is a widening value gap between "legacy" ceramic scrap ($16–$18/kg) and modern plastic ICs ($3.50–$4/kg) due to the higher gold content in older components Alibaba.

* Product Insights:

* High-Value Units: Ceramic CPUs (e.g., Intel 186/286/Pentium) are the most sought-after due to thick gold plating Alibaba.

* RAM & ICs: Gold-fingered RAM modules and IC chips stripped from motherboards are standard trade items.

* Supplier Landscape: Suppliers are often international recycling firms located in regions with high e-waste inflows, such as FR and UG .

2. Metal Machining Scrap Chips (Swarf)

This sector involves processing metal waste (chips, swarf, or shavings) from CNC machining, milling, and drilling for direct return to foundries.

* Market Trends: Sustainability mandates are pushing factories toward "on-site" processing. Compacting loose chips into briquettes reduces logistics costs and improves "melt yield" by minimizing oxidation during remelting BirimrecyclingSciencedirect.

* Product Insights:

* Processing Equipment: Briquetting machines ($4,000–$60,000) are the core hardware used to densify loose aluminum or steel chips into manageable blocks .

* Ancillary Tools: Shredders and screens are used to pre-condition the waste before briquetting.

* Supplier Landscape: Dominance by specialized machinery manufacturers in China (e.g., Henan and Jiangsu regions), focusing on high-pressure hydraulic briquetting technology .
