IMPLEMENTATION OF ENVIRONMENTALLY SOUND TECHNOLOGIES FOR
RE-REFINING/RECYCLING OF WASTE OIL/SLUDGE OIL/USED
The used oil and waste oil management has always been an
environmental concern to our government and the
governments of all countries around the world.
Considering the adverse impact of dumping the used oils
and waste oils into soil or water drains resulting in
severe damage to the environment, the Government of
India Central Pollution Control Board (CPCB) and the
state governing body - Maharashtra Pollution Control
Board set targets to regulate the reprocessing/reuse of
hazardous wastes by application of
environmentally sound technologies.
in May 2003 the CPCB and MPCB made it mandatory for
recycling of hazardous waste collection and processing
units to obtain registration for the reprocessing of
such wastes. The technology requirements to be complied
by the re-refining/recycling industries for used oil and
waste oil are defined by these two entities.
ENVIRONMENTALLY SOUND TECHNOLOGIES (ESTs)
Technology and standards for re-refining / recycling
of used oil and waste oil in an environmentally sound
manner. ESTs stipulated in the HW Rules are as under:
- Vacuum distillation with clay treatment
- Thin-film evaporation process
- Vacuum distillation hydro-treating
- Any technology approved by the MoEF (Ministry of
Environment and Forests).
