With open facilities, the Brazilian Biorenewables National Laboratory (LNBR) serves Brazilian and foreign researchers who wish to use the experimental stations of the Laboratory to carry out their research. Research proposals are submitted through the User Portal system.

Important: Industrial users follow their own process to use the facilities of LNBR for proprietary research. For more information see the Industrial Information. 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.


Standard Proposal

This is the standard procedure for access to LNBR facilities. The submission of proposals is carried out according to the submission schedule of each facility. The user requests time for a specific experiment in a facility. The proposal is evaluated by an Internal Committee for Evaluation of Proposals. If approved, the user is granted time to execute the research proposal. Results published using data obtained at the LNBR must acknowledge and thank the user for the use of the facility, and provide a copy of the article or thesis to the LNBR.


To begin the process of proposal submission, it is necessary for the user to register in the User Portal system. To create an account in the portal, the user must enter a valid e-mail address and click on the “access” button. In his first access, the user must provide personal and professional information.

Important: This registration needs to be done only once, can be done regardless of the proposal submission period, and 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 indicated, choosing the National Laboratory and the facility for submission. Online completion of a general form will be required. After submission, the proposal will be automatically forwarded to the User Support Service (SAU).


The research proposal review process is divided into different 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 of the proposals and experience of the staff, evaluation of previous proposals, and scientific publications based on results obtained previously at the LNBR. The best-evaluated proposals are recommended to receive time to use the facility;
  • Phase 3: Internal evaluation by the safety committee, the proposal that presents a safety risk for execution will have to fill out a specific safety form and pass through the evaluation of a safety committee that will make recommendations for adaptation for the execution of the experiment.

Important: Given the importance of previous scientific results for the overall evaluation process of the proposals, it is recommended that users check and 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 being checked by the library staff and the facility coordination.


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. Consulting information with the facility coordinator is also highly recommended.

The research proposer must have a Ph. 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 for confirming the team that will come to CNPEM, signing the commitment term, and filling out the safety training.

  • Team confirmation – The team that will come to CNPEM may contain the number of members allowed by the facility, the User Portal system is parameterized with the number determined for each facility. The proponent is the one who accesses the system to define and confirm the team;
  • Accommodation – CNPEM has an accommodation facility to accommodate researchers during the period of the proposals. For those who want to use it, reservations must be made to SAU – User Support Services through the e-mail After the request, the user will receive an e-mail with the confirmation or not of the reservation;
  • 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 part. 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 remove 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 next morning;
  • Housing key – The key must be picked up at check-in according to the arrival at CNPEM’s campus.


Every day with no entrance time restriction.

  • Mon to Fri – 8 am to 5 pm – User Support Services (SAU);
  • Mon to Fri – 5 pm to 8 am (during the night) – Central Entrance;
  • Saturdays, Sundays, and holidays (24 hours) – Central Entrance;
  • When there is a need to change apartments for any reason, the request should be made to SAU- User Support Services and outside office hours at the central gate to check availability.


During the week:

  • Mon to Fri – 8 am to 5 pm – User Support Services (SAU);
  • Check-out must be done until 9:30 am on the day of departure.

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.
