Internship - R&D Engineer - Recycling of SiC-based refractory materials (M/W)

  • Research and Development
  • France CAVAILLON
  • Internship
  • Posting date : 11/10/2021

Position description

Refractories are strong materials which can resist elevated temperatures and corrosive atmospheres. For these properties, Saint-Gobain provides high quality refractories to be used as wall protection materials in waste incinerators. Despite its high performance, after several years the refractory lining is damaged due to the extreme conditions and needs to be disposed. Conscious of ever-increasing environmental constraints, Saint-Gobain aims at reducing waste from spent refractories while saving resources. The goal of this 6-months internship is to find solutions to improve the recycling of SiC-based refractory materials.


Thus, your main tasks will be:

  • To study the quality of end-of-life refractory materials collected from waste-to-energy plants and propose adapted recycling solutions to recover clean secondary raw materials, based on a literature review.
  • The second part consists in conducting experimental campaigns to identify levers for the samples recycling. This work would include some physical preparation (grinding, sieving, etc.) and chemical treatments.
  • The last objective consists in reintroducing the clean secondary raw material in optimized proportions in new refractories. Such an approach would enable the production of low-carbon emission solutions with a well-managed lifecycle while keeping performance comparable to the original product.
  • The intern will be expected to develop working relationships with colleagues and collaborators in order to meet the objectives and presents/report his results to the different collaborators in english.


  • You are in your third year of an engineering school specializing in chemistry
  • You have basic English skills
  • You master the Office package (Word, Excel, PowerPoint)
  • You are recognized for your effective communication, your teamwork, your adaptability, your curiosity, your problem-solving, your work ethic and your integrity

Additional Requirements

Saint-Gobain, a world leader in the housing and construction markets, designs, manufactures and distributes high-performance building materials and materials that provide innovative solutions to the challenges of growth, energy efficiency and environmental protection.
