Boart Longyear wireline core retrieval system, an innovation that revolutionized the diamond drilling industry by increasing productivity on the worksite and making tripping core from the bottom of the hole safer for the drilling assistant. Later named the Q Wireline System, the new core retrieval method introduced a level of productivity never before seen in the exploration drilling industry.

Informal e-recycling industry refers to small e-waste recycling workshops with few (if any) automatic procedures and personal protective equipment (PPE).
