Re-use is becoming part of consumer habits and helps reduce waste.

L’Administration de l’environnement

The Administration de l’environnement ‘s mission is to protect the environment and improve the population’s living conditions. It supports public authorities in decision-making by providing expertise and ensures compliance with environmental legislation. It oversees activities that may impact the environment, monitors and assesses environmental quality, and promotes the adoption of more sustainable practices. It also encourages innovation and the development of initiatives that contribute to the ecological transition.

The Environment Administration was created by the law of 27 November 1980, taking over the activities of the Water Division of the former Public Hygiene and Health Institute. Initially composed of the Water, Air and Noise, and Waste divisions, its responsibilities have evolved through successive reforms. A Classified Establishments division was added in 2003, while the Water Division was transferred to the Water Management Administration in 2004.

From 2010 onwards, the administration undertook a broad reorganisation process, supported by audits and consultations. This work led to the development of a reform project presented in 2014, finalised in 2015, and adopted by the Chamber of Deputies on 25 February 2016, marking a new step in the modernisation of the institution.

Emwelt.lu

Emwelt.lu is the official environmental portal of the Luxembourg government. It is managed by the Ministère de l’Environnement, du Climat et de la Biodiversité
, in cooperation with the relevant national administrations such as the L’Administration de l’environnement , l’Administration de la gestion de l’eau, and the l’Administration de la nature et des forêts.
The website serves as a central information platform on environmental issues in Luxembourg. It provides in particular:

• information on biodiversity and nature protection
• content on climate change and climate policies
• data and recommendations on water quality (drinking water, rivers, groundwater)
• information on air quality monitoring
• topics related to waste management, recycling, and the circular economy
• national environmental laws, regulations, and plans
• projects and initiatives linked to sustainable development, the European Green Deal, and the goals of the 2030 Agenda

Methodology

The interviews were conducted online via ILRES’ MyPanel, dan online survey panel in where registered members regularly take part in opinion polls and market research studies in exchange for rewards.
The survey was carried out among 1,497 residents aged 16 and over. The fieldwork took place in December 2025.

Key findings

The study shows that exchanges between relatives and friends remain the dominant practice, followed by digital solutions, which play an increasingly important role in connecting users. Physical shops, social media, and second-hand markets also continue to actively contribute to the circulation of goods, while associations and classified ads remain more secondary but still present channels.
The results highlight the main re-use channels used by residents:

• Friends and family (private donations) rank first with 28.5%
• Online platforms follow with 22.7%
• Shops and retail stores account for 14.1%
• Social media represent 12.5%
• Flea markets and second-hand fairs reach 9.8%
• Associations account for 5.1%
• Local newspaper classifieds account for 3.5%
• Other channels: 3.8 %

These data confirm that re-use is increasingly becoming part of consumer habits and is emerging as an important driver of the circular economy. By extending the lifespan of objects, these practices help reduce waste and limit the environmental impact associated with the production of new goods.

Through which channel do you most often engage in the re-use of objects?
