The kick-off meeting for drawing up the Best Available Techniques REFerence document for Landfills (LAN BREF) took place as a hybrid event from 6 to 9 October 2025, gathering 166 experts—82 in person and 84 online—representing EU Member States, Norway, industry, environmental NGOs, the European Chemicals Agency (ECHA), and European Commission services. This meeting launched the process of developing a standalone BAT reference document specifically for landfills, reflecting their importance and complexity within waste management.

   On 17 August 2025, the European Commission published the Decision establishing the BAT conclusions for Waste Treatment (WT) in the Official Journal of the EU. This BREF focuses on waste treatment technologies but intentionally left landfills out of its scope. The decision to exclude landfills was made deliberately to allow for a dedicated and more comprehensive BAT document addressing landfill-specific issues, which is now being developed through the ongoing LAN BREF process.

   The new amendment of the existing regulation on TRS for pulp mills expands requirements for pulp mills in Chile. Currently, there are seven such facilities in this country, located from the Maule Region to Los Ríos.

   The Ministry of the Environment reported that the update of the Odour Emission Regulation for Pulp Mills has been published in the Official Gazette today, modernising the standards applicable to Kraft or sulphate pulp production, whose processes can generate odours that affect the quality of life of nearby communities.

   The Odour Management Strategy in Chile has resulted in regulatory advances, such as the first environmental odour standard for pig farming, but citizen complaints remain high.

   This study reviews the current state of odour management and outlines planned actions, including sector-specific emission standards and improved implementation. Future efforts will focus on stronger regulations, municipal management with community involvement, and integration with climate change policies. The goal is to enhance odour prevention and control, improving quality of life for affected communities.
