Bitcoin Forum > Bitcoin > Mining > Hardware > Non-Bitcoin Uses for Old ASIC Miners?However, since you mention 'recyclers' specifically; there's quite a few people who sell major components of miners - e.g. individual blades of a miner that has a blade design, heat sinks, controllers, power supplies, etc. For those building or servicing their own miners, older boards to salvage chips from is also not unheard of. But this seems to be more sporadic than an actual business plan. There's little value in taking in old miners and then disassembling those for component resale.
Other than those,full recycling is the same as for most other electronics - i.e. if being processed well they'll separate out the major parts, heat sinks can be resold, fans can be resold, power supplies hold value, and pretty much everything else (PCBs including components) have everything desoldered, the components put on a conveyor belt, an optical system blows anything that looks like an IC off to one bin, everything else goes to scrap, that bin is then processed to reclaim precious metals like gold.
Not uncommonly, it just ends up on a landfill for future generations to deal with.
