A：Used motor oil can be refined via processes like pre-treatment, heating, fractional distillation, catalysis, and decolorization and filtering. Benefits include environmental protection, resource conservation, and economic returns.

A：The valuable products obtained from pyrolysis oil distillation are diesel, asphalt, and non-condensable gases. Learn about the detailed distillation process and how DOING advanced pyrolysis oil distillation equipment ensures efficient results.

A：DOING group has new efficient environmental protection DY series waste plastic pyrolysis machine to recycle waste plastic.

A：Plastic to oil process is the thermal decomposition of plastic waste to fuel oil, carbon black and syn-gas in the absence of oxygen. The whole plastic to oil pyrolysis process is executed in waste plastic pyrolysis machines.
