The Brazilian Biorenewables National Laboratory (LNBR) open-access facilities serve Brazilian and foreign researchers who wish to benefit from the experimental capabilities of the Laboratory to carry out their research. Research proposals are submitted through the User Portal system.

Important: The submission process described below is applicable exclusively to research in the public domain conducted by Academic Users, or by Industrial Users that do not seek intellectual protection for their research. Industrial users that want to use LNBR facilities for proprietary research may use them as a technological service or through collaborative R&D. Additional information on collaboration agreements and intellectual property rights can be found here.


Standard Proposal

The following describes the standard procedure for access to LNBR facilities. Each facility has its own submission proposal schedule. The proposal, to be evaluated by a Committee, shall request time for a specific experiment at a given facility. If approved, the user is granted time to execute it. Published results using data obtained at LNBR must acknowledge the use of the facility. The user must provide a copy of the article or thesis to LNBR.


The proposal submission begins with the user registration at the User Portal system. To create an account, the user must enter a valid e-mail address and click on the “access” button. For the first access, the user must provide personal and professional information.

Important: This registration step is done only once at any time, regardless of the proposal submission period. The information provided can be updated at any time.

Once registered in the User Portal system, the user must click on the link “Research Proposal-Submission and Preparation” and follow the instructions. The user must choose the National Laboratory and the facility of interest and complete an online form. After submission, the proposal will be automatically forwarded to the User Support Service (SAU).


The research proposal review process is divided into phases:

  • Phase 1: Internal evaluation of the proposal by the facility coordinator to judge the technical feasibility of the proposed experiment;
  • Phase 2: The facilities have an Internal Committee for Proposal Evaluation that evaluates and ranks the proposals according to the following criteria: scientific merit, staff experience, evaluation of proposals, and scientific publications from results previously obtained at LNBR. The highest-ranked proposals are recommended for time at the facility;
  • Phase 3: Internal evaluation by the safety committee, the proposal that presents safety risks will have to fill out a specific safety form to be evaluated by a safety committee that will make recommendations for the execution of the experiment.

Important: Given the importance of previous scientific results for the overall evaluation process, it is recommended that users update their publications both in the User Portal system and in the CNPEM Library database. Updates to the library database should be done by sending the complete bibliographic information to the Library (produçã Publications are included after verification by library staff and the facility coordinator.


Before submitting a proposal, it is recommended that users consult the website for available facilities, courses, services, and technologies, as well as specific recommendations for sample preparation, protocols, and other detailed specifications about the research proposal submission process. Consultation with the facility coordinator is highly recommended.

Only Ph.D. researchers can submit proposals. After user registration in the User Portal system, the submission pages will be available only to researchers with a Ph.D.


In the User Portal system

After approval of the research proposal, an e-mail is sent to the proponent with dates for scheduling and instructions, The proponent must confirm the team that will come to CNPEM, sign the term of commitment term, and fill out the safety training.

  • Team confirmation – The User Portal system provides the maximum number of users allowed at each facility. The proponent is responsible to accesses the system and to define and confirm the team;
  • Accommodation – A CNPEM hostel can accommodate researchers during the execution of the proposal. Reservations must be made to SAU – User Support Services through the e-mail After the request, the user will receive a confirmation e-mail if there is availability for the requested dates;
  • Term of commitment – A Term of commitment with rules and obligations to be followed in the realization of the proposal at CNPEM will be available for signature online. Without the signature of the Term of commitment it is not possible to access the facilities;
  • Security training – To access CNPEM all users must take the security training available in the User’s Portal system, in the request for arrival section. The release of the access badge to the facility is made only after the confirmation that the security training was done.

CNPEM’s Code of Conduct

During the experiment, the research proposal team must follow CNPEM’s code of conduct.

Sending of national and international samples

Users who want to bring samples or send them for the realization of the proposal at LNBR should contact the responsible for the facilities to verify the procedure.


  • Badge collection – To collect the badge to access the facility, the user must identify him/herself at CNPEM’s central gate and go to LNBR’s reception. If the arrival at CNPEM happens at night or on weekends and holidays, an access badge to the campus will be given at the front desk, and the user will be directed to LNBR’s reception desk to exchange the badge the following morning;
  • Housing key – The key must be picked up at check-in according to the arrival at CNPEM’s campus.

Payment methods

  • Cash;
  • Debit card;
  • Bank account deposit.

Wi-Fi Access

One week before coming to CNPEM to carry out the research proposal, the User’s Portal system sends an e-mail to all participants of the proposal, with information about the wi-fi access login for use during the period of the proposal. CNPEM is also part of the EDUROAM network to serve external researchers. Questions or problems with Wi-Fi access can be directed to SAU (User Support Services).


After the research proposal is completed, it is strongly recommended that the User fill out the Infrastructure and Services Evaluation Form that is available in the User Portal. It is the responsibility of the proposer and the principal investigator (PI) to make good use of the data made available and distributed to his collaborators.

Important: the user must declare the use of LNBR facilities in any article, thesis, or other published material that uses data obtained in the realization of his proposal. Users must also cooperate in providing such information when requested.
