Towards new frontiers in physics

PEG-SiC slurry recycling:

Indra Scientific has developed a comprehensive solution for the recycling of all waste from silicon wafer sawing operations.

The technology allows us to recycle ALL elements of the sawing slurry.

  1. -we recuperate all PEG

  2. -we recuperate all SiC. We remove SiC particles that are outside the size specification for the slurry. We recycle about 80% of the SiC to be used again in a new slurry. The remaining SiC will be used for other applications such as polishing.

  3. -we recuperate all Si and transform it into mono or poly crystalline PV or electronic grade Si

  4. -our process has a very low energy intensity

  5. -our process does not produce any waste water
