Ragui Ghali's inventions have been very significant and they involve using materials that are filling our landfills, to actually clean up the environment. Absorbent materials have many applications, such as absorbing oil spills and, believe it or not, dehydrating chicken manure. The first significant product developed by Mr. Ghali while working in his new lab as an insulating and packaging foam called Icynene. The isocyanurate molecules allow for high-temperature stability. Urea leads to fire resistance.
Flexibility is achieved with urethane.
It is cheaper than other insulating materials, will not burn in normal air, has no odour and will not release toxic substances. The next product that this inventor developed was called Spilkleen. Believe it or not, it is made from mainly old phone books. The key ingredient is the cellulose in the phone books. The phone books are finely shredded and mixed with binders to stop them from swelling when they absorb liquids.
