JLR Disposal
JLR Disposal, or simply JLR, was a company which specialised in corporate waste disposal. JLR was owned by Jack Robertson, who described it as very efficient and very highly-rated internationally.
By 2018, JLR Disposal was taking the waste from Sheffield Hallam University lab, including their aborted experiments and spider carcasses. The company stored the waste into disused mines, on top of which a luxury hotel was built later. Robertson explained this decision with JLR being "a little overzealous in cutting corners and worried about keeping the bottom line instead of doing the right thing", but shifted responsibility from himself, saying that he just was signing contracts.
