Waste management

Special categories of waste

Waste oils

Waste oil is any oil (plant, animal, mineral, synthetic, industrial, insulation, and/or thermal oil) which is no longer usable for its originally intended purpose.

We differentiate between waste cooking oils and waste lubricating oils.

Waste cooking oils which are degradable and represent non-hazardous waste, comprise all oils resulting from the catering and hospitality sector, industry, trades and crafts, medical services, public services, and other similar activities where more than 20 meals per day are prepared. They are a valuable raw material for the production of biodiesel.

Waste lubricating oils are hazardous waste because 1 litre of oil can contaminate one million litres of water, or permanently pollute the soil because, in general, lubricants are not biodegradable. They represent a valuable raw material because they can be regenerated and used as the raw material for the production of fresh lubricating oils, or in the process of material recovery they can be used to obtain esters used in the production of soap, washing agents and similar. Waste lubricating oils are also a valuable energy generating product in power and

production plants with installed equipment power greater or equal to 3 MW, because this type of recovery prevents environmental pollution.

Waste oils management includes the procedures of collection, pre-treatment/conditioning, and their regeneration or material recovery and energy recovery.

In the process of waste oils management it is prohibited to:

  • discharge waste oils into surface wasters, ground waters, coastal waters, and drainage systems,
  • dispose and/or discharge waste oils detrimental to the soil, as well as any uncontrolled discharge or residues from the waste oils treatment,
  • recover and/or dispose of waste oils causing air pollution above the thresholds stipulated in the regulations in force, and which affect human health, and flora and fauna,
  • collect waste oils into containers that are not duly equipped for holding waste oils.


Waste oils, as one of special categories of waste, have to be collected separately and stored in adequate containers separately for other types of waste.

It is prohibited to mix different categories of waste oils, mixing with other hazardous waste containing PCB/PCT.

Collection of waste oils includes collection, temporary storage, pre-treatment/conditioning, sorting and transport of waste oils from holders to the entities authorised for recovery and/or disposal of waste oils.

Authorised collector of waste oils is a legal or natural person – tradesman that pursuant to the Act on Sustainable Waste Management holds a licence for pursuing the activity of waste oils collection, and under the provisions of the Ordinance on the management of waste oils has concluded with the Fund the contract on collecting waste oils.

They are obliged to accept waste oils from the holders of waste oils and to hand them over free of charge to the company authorised for recovery and/or disposal of waste oils. In the case of collected waste oils for which there is no company in Croatia authorised for material recovery and/or thermal recovery and/or disposal of waste oils, the authorised waste oils collector is obliged to organise, with prior approval of the Fund, recovery and/or disposal of the waste concerned outside the Republic of Croatia and is entitled to the reimbursement of costs.

The holder of waste oils shall hand over the waste oils to the authorised collector together with the completed consignment note and the report on physicochemical properties obtained from a licenced laboratory in the case of quantities exceeding 1 tonne/year, or (if the quantity is less than 1 tonne) supply the declaration on physicochemical properties.

Upon the acceptance of waste oils from the holder of waste oils, the authorised collector is obliged to validate the consignment notes.


Waste recovery is any procedure the main result of which is useful waste recovery when waste replaces other materials that would normally be used for that purpose, or waste that is prepared to fulfil that purpose, in the factory or in the wider economic context.

Waste oils recovery means regeneration and material recovery procedures in which new products are produced, or which allow reuse of waste oils or thermal treatment, i.e. energy recovery of waste oils.

Authorised waste oils treatment operator is a legal or natural person - tradesman holding a licence to pursue the activity of recovery and/or disposal of waste oils, and has a concession for recovery and/or disposal of waste oils.

Authorised recovery operator is obliged to accept from the collector all collected waste oils in category I and II free of charge and validating the consignment note, and to recover them pursuant to the provisions of the Ordinance on the management pf waste oils.


Collecting all generated waste oils and their recovery and/or disposal for the purpose of environmental protection and protection of human health.


Importers and/or introducers of fresh lubricating oils in the Republic of Croatia, and producers of new lubricating oils in Croatia – persons subject to the fee, when they place fresh lubricating oil on the market as an individual product pay to the Fund the fee for the management of disposal of waste lubricating oils, in the amount of 1.00 kn/l.

The amount of the management fee is stipulated in the provision of Article 23 of the Ordinance on the management of waste oils, and the tariff code for fresh lubricating oils on which the management fee is charged are listed in ANNEX 1 to the Ordinance.

The amount of the reimbursement fee for the management cost paid by the Fund to the authorised waste oils collectors for the quantities of waste oils that were collected and handed over for recovery and/or waste oils quantities exported for disposal are laid down in Article 16(4), and Articles 29 and 31 of the Ordinance on the management of waste oils.
