On Wednesday 22 April 2026, the City of Luxembourg (VdL) announced changes to its door-to-door biowaste collection system following its joining of the Minett-Kompost inter-municipal syndicate.

The initiative aims to simplify waste sorting and to encourage greater participation among residents, particularly as biowaste still accounts for nearly one third of mixed household waste.

The updated system expands the list of materials accepted in brown bins to include branches and woody waste, as well as cuttings from bushes, hedges and shrubs, in addition to kitchen waste and grass clippings.

VdL noted that by making biowaste sorting more attractive, it aims to increase citizen participation in brown bin collection, noting that biowaste still represents nearly one third of the weight of mixed municipal household waste (black bins).

The list of waste accepted in brown bins now includes:

  • garden waste and grass clippings, namely branches and woody waste; cuttings from bushes, hedges and shrubs; flowers and perennial plants; herbs and weeds; leaves, grass and potting soil;

  • kitchen organic waste, including leftovers; fruit and vegetable scraps; coffee or tea grounds; shells and crustaceans; and eggshells.

The VdL pointed out that it is no longer possible to place additional containers next to the brown bin. Only biowaste placed directly in the bin provided by the City will be collected during the weekly collection. If the volume of garden waste exceeds the capacity of the brown bin, the Hygiene Service offers a paid bulk collection on request or free disposal at the resource centre.

Once collected, the biowaste is transported to the Minett-Kompost facility in Mondercange, where it is treated through methanisation. This process converts biowaste into biogas and compost.

Kitchen organic waste and grass contribute to biogas production, while other garden waste acts as structural material that helps ensure suitable processing conditions. The remaining material is then recovered as compost. Garden waste from larger-scale works, collected on request, is shredded and processed into compost or wood chips for heating.

Through awareness-raising efforts and optimised collection management, the VdL said it aims to increase waste recycling rates, strengthen the production of compost and renewable energy, particularly biogas, and offer citizens the opportunity to reduce their waste collection tax.
