Rotawave Ltd has a patented microwave based
process that allows for the extraction of water,
petroleum products and organic oils at very low
cost from various resources, including oil drill
cuttings, refinery and food waste streams and biomass.

The technology is based on the advanced
simultaneous use of multiple electromagnetic
frequencies and a unique ceramic phase
separation drum. This maximizes heat and
mass transfer within the system hence reducing
plant size, material hold up and operating costs.
In addition the low intensity thermal regimes
required allow oils to be recovered with no
degradation. Solid end products vary from inert
minerals to high calorific value chars.

Rotawave's technology is finding application in
areas as diverse as activate carbon regeneration,
sterilization and rendering of food wastes,
pyrolysis, soil decontamination, and extraction of
oils from biomass and conversion into renewable fuels.
