RFP Title


Technology to Reduce Rubber Odor
RFP Description

NineSigma, representing a large global manufacturer of automobile parts, seeks technologies to reduce rubber odor. Specific targets include deodorants or compounding agents for producing odorless reclaimed/vulcanized rubber products, and technologies for eliminating rubber odor components that can be incorporated in reclaimed rubber manufacturing lines.

Key Success Criteria


  • Target materials
    • Vulcanized rubber (ethylene propylene diene rubber)
    • Reclaimed rubber (rubber reclaimed by cutting, heating, and devulcanized rubber)
  • Target odor components
    • Ethylidene-norbornene, thiophene, sulfide, amine, aldehyde, alcohol, thiazole, etc.


Technology requirements

The Client seeks technologies for either one or both of A and B below:


A. Technologies to reduce odor caused by sulfur or polymers during the manufacture of reclaimed/vulcanized rubber products

  • Odor reduction level:
    • Reduces odor from 4 to 3.5 on the six-point scale for odor intensity (see website below):
      • Preferably improvement of odor intensity to 2 or less eventually by the improvement of the proposed technology and combination with other technologies.
  • Preferably reduction of both odors caused by vulcanized compounding ingredients and by polymers.
  • Preferably no deterioration in appearance and performance of final product.


B. Technology to eliminate rubber odor substances generated during the manufacture of reclaimed rubber products.

  • Reduction level of the above target odor ingredients:
    • Reduces odor from 4 to 3.5 on the six-point scale for odor intensity
      • Preferably improvement of odor intensity to 2 or less eventually by the improvement of the proposed technology and combination with other technologies.
  • Preferably capable of continuous processing
  • Even better if the odor of the final product can be reduced by eliminating rubber odor components generated during the manufacturing process.

The Client aims to achieve targets by combining the proposed technology with their own know-how and technologies as needed. Accordingly, proposals not meeting the above requirements at this point are welcome.


Proposer requirements

  • Submission of data showing odor reduction effects
  • Capable of conducting sample or demo tests.
Possible Approaches

Possible Approaches

The Client expects technologies such as the following approaches, but is open to others:

  • Deodorants that can be blended into rubber
  • Improvement of vulcanizing compounding agents
  • Improvement of reclaimed rubber manufacturing process
  • Various deodorizing techniques:
    • Ozone deodorization
    • Adsorption
    • Plasma deodorization
    • Photocatalyst deodorization
    • Biological deodorization
Approaches not of Interest

The following approaches are not of interest:

  • Reduction of the additive amount of vulcanizing compounding agents
Items to be Submitted


Recently, the significance of rubber recycling technology has been increased to build a sustainable recycling-oriented society. The Client is engaged in the development and manufacture of automotive parts made of vulcanized and reclaimed rubber. In the Asian market, which has been growing increasingly important in recent years, a tendency to avoid rubber odor has prevented the widespread use of reclaimed rubber with strong odor. The Client has been developing the technology to reduce the odor of reclaimed/vulcanized rubber. Expecting that there exist promising technologies for solving this problem around the world, the Client decided to invite proposals to accelerate technology development.


Notes on Response

Proposal shall have clear points and should not include confidential information. Supplemental files may be submitted in addition to the proposal.


Response evaluation

The client will evaluate all responses with the following criteria.

  • Overall scientific and technical merit
  • Approach to proof of concept or performance
  • Economic potential of concept
  • Realism of the proposed plan (action items, timeline, roles, deliverables, cost estimation)
  • Potential for proprietary position
  • Respondents’ capability and related experiences


Anticipated Project Process

After the submission due date, the client will review all submitted proposals. NineSigma will send the review results to each proposer 6-8 weeks after the due date. The client possibly asks clarifying questions before selecting the most suitable candidates for collaboration. The client will select best candidates through evaluations. During the selection process, the client may execute NDA with selected respondents, seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreements with the selected respondents and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.
