What’s Required
Switzerland’s Ordinance on the Avoidance and Disposal of Waste, commonly referred to as the ADWO, establishes mandatory requirements for preventing waste and ensuring that unavoidable waste is recovered or disposed of safely and efficiently.
The ordinance applies to waste generators, construction companies, industrial operators, recycling businesses, waste-treatment facilities, landfill operators, municipalities and cantonal authorities.
Key requirements include:
Preventing waste wherever technically and economically feasible.
Separating recyclable materials from other waste streams.
Prioritising preparation for reuse and material recovery over energy recovery or disposal where this produces a better environmental outcome.
Ensuring that waste is treated using environmentally compatible processes.
Sending waste only to suitable and authorised recovery, treatment or disposal facilities.
Complying with technical standards for waste-treatment plants, incinerators and landfills.
Characterising or testing waste where its composition or disposal route is uncertain.
Maintaining operating records, waste analyses and documentation required by the competent authority.
Managing construction and demolition waste through appropriate separation, treatment and recovery procedures.
Separating excavated and removed materials according to their contamination status and intended disposal route.
Recovering valuable materials, including metals, mineral fractions and phosphorus, where specific recovery duties apply.
Preventing hazardous substances from entering unsuitable recycling streams or being deposited at facilities that are not authorised to receive them.
Operating waste facilities according to approved operating regulations and state-of-the-art technical standards.
Swiss environmental legislation places waste prevention first, followed by preparation for reuse and material recovery when these options are technically possible, economically viable and environmentally preferable.
Important Deadlines
The ADWO does not establish one universal annual compliance deadline. Most duties apply continuously or are triggered by specific activities, projects or authority decisions.
Important timing requirements include:
Before construction begins: Project owners may need to prepare a waste-management plan where substantial quantities of construction waste are expected or where contamination is suspected.
Before waste is transferred: Waste must be correctly classified and directed to a facility authorised and technically capable of receiving it.
During construction and demolition, required waste streams and excavated materials must be separated, documented, and managed according to their properties.
During facility operation: Treatment plants and landfills must continuously meet their permit conditions, technical standards, monitoring requirements and operating rules.
After facility closure: Landfill operators may remain responsible for monitoring, maintenance and aftercare for the period determined by the authorities.
Authority deadlines: Cantonal authorities may set binding dates for investigations, corrective actions, infrastructure upgrades or changes to waste-management practices.
From 2026: The amended ordinance introduces mandatory phosphorus recovery, including partial recovery from sewage sludge and full recovery from animal and bone meal.
From spring 2026: Amendments strengthen the priority given to preparing waste for reuse and material recycling within the Swiss waste hierarchy.
Businesses should also verify applicable cantonal rules because local authorities may establish additional operational, reporting and permitting deadlines.
Current Status
The ADWO is currently in force.
It entered into force on 1 January 2016, replacing Switzerland’s former Technical Ordinance on Waste. It has subsequently been amended several times to strengthen resource conservation, recycling, disposal security, energy recovery and the circular economy.
The ordinance forms part of Switzerland’s broader federal waste-law framework alongside:
The Environmental Protection Act.
The Federal Act on the Protection of Waters.
The Ordinance on Movements of Waste.
The Ordinance on the Return, Take-Back and Disposal of Electrical and Electronic Equipment.
The Ordinance on Beverage Containers.
Regulations concerning prepaid disposal fees for batteries and glass containers.
Cantonal waste legislation and permit requirements.
The cantons primarily carry out implementation. The Federal Office for the Environment supports and coordinates cantonal enforcement, develops implementation guidance and carries out direct federal enforcement in certain areas, including transboundary waste movements and some waste-financing systems.
Further amendments are expected as Switzerland implements its strengthened circular-economy framework following the 2024 revision of the Environmental Protection Act and related legislation.
Penalties for Non-Compliance
The ADWO does not contain a single standalone penalty schedule for every type of infringement. Enforcement generally occurs under the Environmental Protection Act, cantonal environmental laws, facility permits and binding authority decisions.
Possible consequences include:
Administrative orders requiring corrective action.
Requirements to separate, remove, treat or properly dispose of waste.
Suspension or restriction of waste-handling activities.
Refusal, amendment, suspension or withdrawal of facility permits.
Mandatory waste investigations or laboratory testing.
Remediation or clean-up obligations.
Recovery of inspection, treatment, disposal and remediation costs.
Administrative fines.
Criminal sanctions for serious or intentional environmental offences.
Liability for environmental damage or contamination.
Closure or restriction of a landfill or waste-treatment installation.
Authorities may also require an operator to upgrade its facilities, revise operating procedures or stop accepting particular waste streams until compliance has been restored.
Examples of Known or Potential Violations
Examples of conduct that may breach the ADWO include:
Sending recyclable waste directly to disposal when material recovery is required and reasonably feasible.
Mixing hazardous or contaminated waste with clean waste to reduce its apparent contamination level.
Delivering waste to a facility that is not authorised to receive that category of waste.
Disposing of waste in an unauthorised location.
Failing to separate construction and demolition waste into required fractions.
Reusing contaminated excavated material without the necessary assessment or protective measures.
Depositing waste in a landfill category that is not approved for that material.
Operating a waste-treatment facility without the required cantonal permit.
Accepting waste that falls outside a facility’s authorised operating scope.
Failing to conduct required waste analysis before treatment or disposal.
Providing incomplete or inaccurate information about a waste stream.
Failing to maintain required operating records or monitoring data.
Exceeding technical limits for waste accepted at a landfill.
Failing to recover materials where recovery is legally required.
Improperly storing waste in a manner that creates risks to soil, groundwater, surface water or air.
Failing to implement ordered corrective measures within the deadline set by the authority.
Operating a landfill without complying with monitoring, sealing, drainage or aftercare requirements.
Failing to prepare or follow a required construction waste-management plan.
Whether a specific activity constitutes an offence depends on the waste type, facility permit, applicable cantonal rules and the circumstances of the case.
