Supercritical answer to waste oil found

Lubricating oils deteriorate and oxidize with use as well as accumulating particles from the engines and other machinery in which they are used. Ultimately, their effectiveness worsens and they begin to damage the components they were designed to protect they have to be replaced. Disposing of waste engine oil thus becomes a significant environmental concern. Waste lubricant cannot be simply disposed of as it is highly toxic to ecosystems and harmful to the environment and human health.
