Environmental liability, sanctions and waste rules in Uruguay

Last verified: 2026-10-27 · Status: Stable

Everyone must refrain from acts that seriously deplete, destroy or pollute the environment, and whoever causes environmental damage in breach of the law is civilly liable for all harm and must restore the environment, or mitigate it if restoration is impossible. The Ministerio de Ambiente can demand guarantees, suspend activities, seize goods, suspend or cancel permits and fine from 10 UR to 50,000 UR (about US$483 to US$2.4 million), and anyone may sue to protect the environment as a diffuse interest. Under the waste law (Ley 19.829) every generator bears the cost of managing its waste through its life cycle, manufacturers and importers of special waste products carry extended producer responsibility, and open burning of waste is banned.

The rule

1. Individuals and companies, public and private, must refrain from any act that causes serious depletion, destruction or pollution of the environment; acts that breach the general environmental law or the other rules on the matters it covers are deemed to be such acts. Environmental damage means any significant loss, decrease or detriment caused to the environment. Environmental policy is based on prevention and precaution: where there is danger of serious or irreversible damage, lack of absolute scientific certainty cannot be invoked to avoid preventive measures.
Cost to do it: No fee; cost of environmental management systems proportionate to the risk of the activity.
Example: A tannery discharging effluent above permitted limits breaches the art. 3 duty because it contravenes environmental rules. / A foreign agribusiness cannot rely on scientific uncertainty to avoid preventive measures where serious damage is possible.Ley Nº 17.283 (General Environmental Protection Law), art. 3 and 6; Ley Nº 16.466 art. 3, Ley 17.283 art. 3 and 6, 2000-11-28 official text · verified 2026-10-27

2. Whoever causes depletion, destruction or pollution of the environment in breach of the law is civilly liable for all damage caused and must, where materially possible, carry out the actions needed to restore it. Where the damage is irreversible, the person responsible must take all measures for its maximum reduction or mitigation, without prejudice to administrative, civil or criminal liability. If the person responsible delays or resists restoration or mitigation, the authority may ask the court to impose daily penalties (astreintes) or impose them itself, at the offender's cost. Under the waste law, persons are liable for damage caused by waste management even if they hold the required authorizations.
Cost to do it: Restoration cost can far exceed fines; environmental insurance and contractual indemnities are the usual mitigants.
Example: A logistics company whose tank leaks fuel into a stream must pay for clean up and compensate neighbours, and faces daily penalties if it delays. / A foreign buyer of an industrial site should price historic contamination: holding a permit does not shield waste related damage under Ley 19.829 art. 62.Ley Nº 16.466 art. 4; Ley Nº 17.283 art. 16; Ley Nº 19.829 art. 62, Ley 16.466 art. 4; Ley 17.283 art. 16; Ley 19.829 art. 62, 2019-09-18 official text · verified 2026-10-27

3. To secure compliance the Ministry may issue acts and carry out works to prevent, stop, reduce, monitor and correct environmental harm; impose treatment of waste or emissions and self monitoring by generators; require a real or personal guarantee for compliance or for possible damage to the environment or third parties; order preventive suspension of a presumably dangerous activity while it investigates; and take precautionary seizure of objects or products of the presumed infraction.
Cost to do it: Cost of guarantees and self monitoring set by the Ministry; amounts are set case by case.
Example: A Uruguayan chemical plant may be required to post a bank guarantee covering possible damage before expanding. / A foreign mining company can have operations preventively suspended while the Ministry investigates a suspected spill.Ley Nº 17.283, art. 14; Ley Nº 19.889 art. 293 and 294, Ley 17.283 art. 14; Ley 19.889 art. 294, 2020-07-09 official text · verified 2026-10-27

4. Infractions of environmental rules are punished by fines from 10 UR to 50,000 UR. In addition the Ministry may: warn first time offenders for minor infractions; for non minor infractions, publish the sanction at the offender's cost in two national newspapers and one local newspaper; confiscate objects and products of the infraction and the vehicles, vessels, aircraft and equipment used, whoever owns them, or their market value if confiscation is impossible; and suspend for up to 180 days, or for serious, repeat or continuing infractions cancel, the registrations, licences, authorizations, permits or concessions under its competence. The Ministry may also bring the collective action for diffuse interests, which anyone interested, the public prosecutor and qualified associations may also bring to defend the environment.
Cost to do it: Fines from 10 UR (about UYU 19,408, US$483) to 50,000 UR (about UYU 97,038,500, US$2.41 million); plus confiscation, publication and suspension or cancellation of permits.
Example: A sand extraction company working without its permit can lose its trucks to confiscation and have its mining registration suspended for up to 180 days. / For a foreign investor the fine ceiling is about US$2.41 million, but cancellation of an operating permit can halt the business.Ley Nº 16.112 art. 6 as reworded by Ley Nº 19.535 art. 168; Ley Nº 17.283 art. 15 (literal D as reworded by Ley Nº 19.355 art. 509); Código General del Proceso art. 42, Ley 16.112 art. 6; Ley 17.283 art. 15; CGP art. 42, 2017-09-25 official text · verified 2026-10-27

5. The State and all public and private persons must minimize waste generation and manage waste according to the law. Every generator of any type of waste is responsible for its management at all stages and bears the cost, except as the law provides, and may use third parties only if they are duly authorized. The Ministerio de Ambiente regulates the generation, collection, transport, storage, trade, recycling and other recovery, treatment and final disposal of all waste, following the waste hierarchy. From the law's promulgation, open burning of waste is prohibited, as are animals and outsiders entering landfills.
Cost to do it: Cost of contracting authorized waste carriers and treatment; no general fee in the law.
Example: A Montevideo restaurant must hand its waste only to authorized operators and bears the cost of doing so. / A foreign manufacturer that hires an unlicensed carrier remains responsible as generator if the waste is dumped.Ley Nº 19.829 (Integrated Waste Management), art. 6, 7 and 52; Ley Nº 17.283 art. 21 as reworded by Ley Nº 19.996 art. 265, Ley 19.829 art. 6, 7 and 52; Ley 17.283 art. 21, 2019-09-18 official text · verified 2026-10-27

6. Only persons registered with the environment ministry may manufacture or import products subject to special waste rules. Manufacturers and importers bear extended responsibility for managing the special waste their products generate, except where the products are taxed by the specific internal tax (IMESI) under the law. Retailers and other distributors of these products, including packaging, must accept their return at the end of their useful life as set in the management plans. Importers and manufacturers using non returnable packaging must minimize its volume and weight, and the Executive may restrict or ban certain packaging materials. The law is regulated by Decreto Nº 213/025 of 20 October 2025.
Cost to do it: Cost of registration and of joining or funding a take back programme for the products concerned.
Example: A tyre or battery importer must be registered and finance the collection of end of life products under its management plan. / A US consumer goods company importing into Uruguay should budget for packaging take back obligations and possible material restrictions.Ley Nº 19.829, art. 39, 40, 41 and 44, art. 39 to 44, 2019-09-18 official text · verified 2026-10-27

7. Export of waste is prohibited to Basel Convention parties that have banned its import, to any State that has not consented in writing to the import of hazardous or other Basel waste or where there is reason to believe the waste will not be managed soundly, and where the Executive declares that domestic facilities are sufficient or that scarcity of the materials would harm the economy. Infractions of the waste law are sanctioned under Ley 16.112 art. 6, Ley 16.466 art. 4 and Ley 17.283 art. 15.
Cost to do it: Same sanction scale as other environmental infractions, up to 50,000 UR (about UYU 97,038,500, US$2.41 million).
Example: A Uruguayan recycler cannot ship hazardous scrap to a country that has not given written consent under the Basel procedure. / A foreign trader exporting waste from a Uruguayan free zone needs the importing State's written consent where Basel rules apply.Ley Nº 19.829, art. 63 and 68, art. 63 and 68, 2019-09-18 official text · verified 2026-10-27

Worked example

Spill case: a plant spills effluent into a river. The Ministry orders preventive suspension (Ley 17.283 art. 14 D), fines the company, say, 5,000 UR (about UYU 9,703,850, US$241,329), publishes the sanction at its cost and orders restoration; delay triggers daily penalties (art. 16), and neighbours or an NGO may sue for the diffuse interest (CGP art. 42).
Packaging: an importer of bottled drinks must minimize packaging weight and participate in the take back scheme set in the management plans, and retailers must accept returned packaging (Ley 19.829 art. 40 and 44).
Due diligence: a buyer of a factory site discovers buried waste. Whoever caused the damage must restore it (Ley 16.466 art. 4), successors of landholders are jointly liable for works done without the required environmental authorization (Ley 16.466 art. 11), and a permit does not exclude liability for damage from waste management (Ley 19.829 art. 62), so the buyer should secure indemnities and a price adjustment.

Step by step

Map emissions, effluents, hazardous substances and waste streams and check permits for each.
Use only authorized waste carriers and treatment operators and keep traceability records.
Check whether your products or packaging fall under special waste rules and register as manufacturer or importer.
Budget for guarantees, self monitoring and take back programmes required by the Ministry.
In acquisitions, run environmental due diligence, including contamination and permit history, and negotiate indemnities.
Prepare an incident response plan to stop harm quickly and start restoration, reducing exposure to daily penalties.

Common traps

Permits do not exclude civil liability for waste related damage.
Confiscation can reach vehicles and equipment owned by third parties, such as leased trucks.
Serious or repeated infractions can lead to cancellation, not just suspension, of permits.
Any interested person or NGO can sue to protect the environment as a diffuse interest.
Open burning of waste is banned, including on rural properties.
Fines are set in UR and rise with wage inflation.
