Waste to Resource

Roy Research and Technology has invented a technology to recycle waste like asphalt or coal tar and solid waste to make products. Bitumen as asphalt or coal tar is available as bottom waste from petroleum refinery and steel industries. The process recovers hydrocarbons from left over asphaltic tar sand and converts them to products.

Recycle waste from petroleum refinery and steel industry to make :

  1. improving  the flotation and buoyancy of ships
  2. lightweight insulated and  sandwich panel
  3. insulated solar backing
  4. filler material for hollow structural   section
  5. encapsulation of nuclear waste
  6. building insulation
  7. composite material as bulletproof vest
  8. spray blanketing material for coal powder or mineral powder/stone chips during transpor
  9. encapsulation of nuclear solid waste.
  10. road carpeting and improving river side and ocean side embankment.
  11. low-cost energy conservation system  by utilizing agriculture based reactive product for roofing
  12. void filling like filling of steel tubes, channel to improve structural strength and prevent corrosion (this was tested and certified by Govt. of India’s Ministry of Defense.)

The technology was patented and published in the USA, Canada, Spain, Mexico, Japan, UK, Italy, France, Denmark, Brazil, Germany, India and describes the method of utilizing asphalt and coal tar through eco-friendly process.

In this process leftover hydrocarbon is extracted and solid bitumen waste is liquefied during fusion with hydroxyl fatty oil. This technology replaces CFC with ethanol reactivated eco-friendly blowing agent or cell former. The products absorbs sound excellently, with damping properties.

Roy Research and Technology’s invention under United Kingdom patent publication describes various solid waste materials as fillers with various properties. Waste metallic fillers, ceramic fillers, various clays fly ash, cinders, and various slag powders.

 The materials that can be used with this technology:

  1. Sand, soapstone, steatite, talc and clay.
  2. Fly ash, cinders, various slags, red mud form the aluminium industry) glass frits, calcium and   magnesium sulphates (paper industry wastes), poly-isocyanate pitch, fertilizer waste, molasses waste, copper mud and phosphate waste (fire retardant).
  3. coconut shell powder, cashew nut shell liquid (CNSL) resins, rice husks, straw powder, wood shavings and charcoal powder.
  4. Gypsum, limestone, calcite, dolomite, magnesite, basalt or granite powder (especially from deep strata like goldmines) and marble dust.
