Recycling of composites

Aerospace

Composite materials are used in a wide range of applications such as aviation, automotive, aerospace and renewable energy industries. The composite content is growing in almost every engineering sector and many manufacturers of high value products are increasingly employing composites to take advantage of their strength, stiffness, durability, corrosion resistance and light weight. According to some experts, in 10 years, there may be more composite going into wind turbines than into all aircraft.

 

Parallel to this increasing demand, the issue of recycling of composites becomes paramount. According to the withdrawal figures from the worldwide Boeing and Airbus fleet, from 2015 onwards, a steep increase of decommissioned aircraft is to be expected.

 

The increasing use of carbon fiber reinforced polymers (CFRPs) has raised an environmental and economic awareness for the need to recycle the CFRP waste. The current and future waste management and environmental legislation require all engineering materials to be properly recovered and recycled, from end-of-life products such as aircrafts, cars and wind turbines.

 

Our technology for treatment and recycling of waste from composites values the complete waste from composites which is being generated during production in the aviation and other related industries (automotive, wind energy, sports equipment). It is also applicable to treat and recover the waste from decommissioned aircraft. Why not recycle and convert an expensive waste disposal into a profitable reusable material?

 

Waste from the use of composites that are produced in industry are the following:

  • Glass fiber fabric waste
  • Waste of carbon fiber rolls
  • Cured pieces that did not pass quality control
  • Pre-pegs (scrap) 

Our technology proposes the treatment of these types of waste and, after application of our process, the end products are oil (for electrical energy), carbon fiber and/or glass fiber.

 

Why use our technology?

  • Less cost involved during the treatment process
  • Absence of contaminating emissions
  • Improved pyrolysis procedures
  • Relatively low investment when compared with other methods
  • Less stages and equipment needed during the recycling process

 

Our process will obtain:

 

Carbon fiber:

61-62% Clean Carbon Fiber

27-30% oils

7-9% gas

 

Glass fiber:

65-68% Clean glass fiber

22-25% oils

5-8% de Gas
