Regulations require bars and restaurants to recycle the vegetable oil used in their kitchens because it helps reduce pollution in our environment. 1 litre of oil contaminates 1,000 litres of water. Disposing of these oils in treatment plants can be a very difficult task and consumes a lot of energy. The oil, when mixed with other solids, leads to obstructions in the sewage system. It becomes food for rodents and encourages breeding.

NIMA number


-What is NIMA?
NIMA (Número de Identificación Medio Ambiental) is the code that uniquely identifies each and every one of the centres registered as producers* and/or waste managers.


NIMA is a code used at a state level, so all centres that produce, transport or manage waste, regardless of their location, have an associated NIMA that must be known by the public administrations and private entities with which that centre participates, thus allowing the electronic exchange of data between all participating actors.


NIMAs must be compulsorily referenced in the hazardous waste control documents used each time a hazardous waste is transferred from a production centre to a management facility.


In the same way that a NIF is associated with a company, the NIMA is associated with a centre, understood as one or several installations subject to different authorisations, located on the same site and whose holder is the same natural or legal person.


*Waste producer is defined as “any natural or legal person who has an activity that produces waste (initial waste producer) or any person who carries out pre-processing, mixing or other operations resulting in a change in the nature or composition of this waste”. (Article 3.i) of Law 22/2011 of 28 July 2011 on waste and contaminated soil)



-Who assigns the NIMAs?
The Autonomous Community where the centre is located will be in charge of registering the centre’s data and assigning its NIMA code.
As  registration, the Autonomous Community that owns the register will be in charge of updating and deleting it, which, as mentioned above, will be the one where the centre is located.

In Balearic Islands, NIMA are assigned by the Ministry of the Environment and Territory of the Balearic Government

List of producers from the Balearic Islands (external link to Balearic Government’s website)


-How are the centers coded?

The NIMA code is made up of a ten-digit numerical code, the first two referring to the INE (National Institute of Statistics) code of the province where the centre is located and the remaining eight digits will be managed by each CA as a counter.



(Art. 41 of Law 8/2019, on waste and contaminated soil of the Balearic Islands)

In application of the second transitory disposition of Law 8/2019 on waste and contaminated soils of the Balearic Islands, the communication procedure of waste production for inscription in the register can only be carried out telematically.


-REGISTRATION AS A PRODUCER OF WASTE. The formalisation of the communication prior to the start of the activity must be done through this link (external link to the Balearic Government website)

A new discharge is considered if the changes affect:

– Location of the place where the waste is generated
– For the start of hazardous waste generation. (New registrations or existing registrations that do not have hazardous)
– For starting to produce 10,000 kg/year of hazardous waste
– For going on to produce more than 1,000 tons/year of non-hazardous
– By change of CIF of the holder


NIMA PROCESSING FOR CUSTOMERS OF CA NA NEGRATA SA: We offer our customers the free advice for processing of the NIMA code (the customer will only have to pay the fee of the Balearic Government. Approx. 50,80 €)


To process it, you will have to contact us at this link. In order to carry out the procedure, the applicant must have the following requirements:

Digital certificate correctly installed (you can request it at the Tax Office or your tax consultant) and an updated operating system installed on your computer.

NIF of the holder or CIF of the company in a PDF. If you are a company, you must provide your CIF, administrator’s NIF and deeds, all in PDF format and separate files.

Send it to the email: residuos@reciclanegreta.com


-MODIFICATIONS OR WITHDRAWALS OF WASTE PRODUCERS. The modifications or cancellations of previous communications already presented, must be done through the following form (external link to the Balearic Government website).


Once they are registered as producers, they will be registered in Balearic Islands’ Registry of Production and Management of Resorts and will appear in the List of Producers that is published periodically on the Balearic Government’s website.

Warning: The correct communications will not be answered by letter, they will appear in the list directly.



Producers of non-hazardous waste that generate less than 1,000 tonnes per year and persons or entities that have obtained authorisation as managers of waste treatment facilities and that also produce waste as a result of their activity are exempt from submitting prior producer notification. Nevertheless, the above maintains the consideration of producers of waste for the other purposes regulated in the waste law or in any other regulation that affects them.


If you have any doubts, please contact our environmental technicians.
