De los datos a la acción: Guía para usar la base de datos anti-incineración
Esta base de datos nace como una respuesta colectiva frente a la creciente ola de proyectos que promueven falsas soluciones para la gestión de residuos en América Latina y otras regiones del Sur Global. Incineradoras, plantas de “waste to energy”, co-procesamiento en cementeras o reciclaje químico, se presentan como respuestas técnicas modernas, pero en la práctica reproducen impactos profundos y desiguales sobre los territorios, las comunidades y los sistemas públicos de gestión de residuos.
En este contexto, las organizaciones sociales, ambientales y comunitarias no pueden enfrentar estos proyectos únicamente desde la indignación o la urgencia del conflicto, por más legítimas que estas emociones sean. La experiencia en los territorios ha demostrado que quienes impulsan estas tecnologías se amparan en lenguajes técnicos, estudios fragmentados y marcos regulatorios complejos que buscan desplazar el debate hacia terrenos donde las comunidades o siempre cuentan con herramientas suficientes para responder.
Esta base de datos surge, entonces, para equilibrar esa asimetría, poniendo al alcance de las organizaciones evidencia científica, académica y técnica que permita sostener las luchas desde argumentos sólidos, verificables y contextualizados.
El objetivo no es reemplazar la experiencia territorial ni despolitizar los conflictos, sino articular el conocimiento técnico con la realidad vivida. La quema de residuos no es solo un problema ambiental, tiene impactos económicos, sociales, sanitarios y políticos que se entrecruzan. Afectan presupuestos públicos, redefine modelos de desarrollo local, afectan la salud de las comunidades, debilitan el trabajo del movimiento reciclador y consolidan decisiones tomadas sin participación real.
Esta base de datos busca ofrecer una mirada integral de estos impactos, demostrando que las falsas soluciones no pueden evaluarse de forma aislada, sino como parte de un modelo que profundiza desigualdades y sacrifica territorios en nombre de la eficiencia.

Le zéro déchet comme stratégie climatique efficace : éviter les compromis de réchauffement liés à l’incinération
Le présent rapport évalue les impacts à long terme sur le réchauffement climatique de trois stratégies de gestion des déchets : les pratiques basées sur l’élimination classique (« Business As Usual » ou BAU) comme la mise en dépotoir ou en décharge, l’incinération et les pratiques zéro déchet comme le tri à la source ou le traitement des déchets organiques et des déchets recyclables. L’analyse se concentre sur trois contextes urbains, à savoir Lagos (Nigeria), Barueri (Brésil) et Quezon City (Philippines), et calcule les impacts prévus sur la température pour chacune des stratégies jusqu’en 2060 à l’aide de l’outil d’estimation des émissions des déchets solides (SWEET) et du modèle climatique FaIR (Finite Amplitude Impulse Response).
Reducing food waste at the local level
Zero Waste Europe, together with Slow Food created a briefing, aimed at providing support to local municipalities to help reduce food waste through a holistic approach enabling the transition towards a sustainable food system.
The guidance outlines the various actions that a municipality can implement to influence food waste reduction and stimulate its sustainable local food system. The guidance highlights examples of how similar policies have been successfully implemented throughout Europe.
Comprehensive Guidance for effective bio-waste management in the EU
The LIFE BIOBEST Comprehensive Guidance presents key policy recommendations to strengthen the EU legal framework for bio-waste management. Drawing from extensive research and stakeholder consultation, this document outlines three interconnected areas for improvement: boosting effective models for separate collection and recycling, promoting reliable markets for compost and digestate, and enhancing monitoring and enforcement of bio-waste regulations.
The guidance provides concrete policy measures to help close the gap between current practices and potential capture rates, addressing the fact that only 26% of kitchen waste is currently collected separately in the EU. It proposes specific legally binding targets, economic instruments, and monitoring requirements to support the EU’s transition toward more efficient bio-waste management and healthier soils.
Validated by 21 stakeholders representing 13 entities from across Europe, this document serves as a roadmap for EU policymakers working to improve bio-waste management.
A summary video presenting the key recommendations is available with subtitles in 11 EU languages.
Fighting climate change, one bio-waste bin at a time – how the #ForkToFarm project supports Montenegro’s environmental transition
In this interactive case study, we try to bring to life the work led by our member Zero Waste Montenegro during the #ForkToFarm project between 2024-25.
Montenegro continues to face significant pressure when it comes to its waste management, with organic waste central to this challenge as it represents around 40% of Montenegro’s waste stream. Most municipalities lack operational capacity and sufficient infrastructure for proper organic waste management. But this challenge is also an opportunity, given the speed at which decentralised, community-driven solutions can be implemented at a low cost to local authorities.
This case study combines data and qualitative analysis with visual footage and content of the work done by Zero Waste Montenegro over the last 2 years to improve the amount of organic waste which is composted rather than landfilled in its partner communities, which includes the capital city, Podgorica. It showcases the first working examples of decentralised organic waste solutions and their successful impact, with videos and interviews with the leaders behind these progressive policies.
NDC Tracker
GAIA’s NDC Tracker aims to provide quick data and country profiles through the lens of the Environmental Justice Principles for Fast Action on Waste and Methane, which guides policymakers on how to craft programs and policies for tackling methane that can also help address interconnected equity issues. With this tracker, we hope to support communities with monitoring country-level commitments and progress, identifying gaps and opportunities to advance this critical agenda.

Blending More Problems: Co-firing Biomass with Power Plants
Co-firing biomass is a technology that burns biomass alongside other fuels, typically coal, in existing power plants. This technology presents a different set of complexities and harms. In the context of ADB’s policy to support the early retirement of coal-based power plants—including decommissioning of coal-fired power plants and site redevelopment for new economic activity—co-firing of biomass with power plants, whether from energy crops or biomass waste, poses risks with long-term harms to air quality, local communities, ecosystems and efforts to address the triple planetary crisis of climate change, pollution, and biodiversity loss in a region most vulnerable to these interlinked threats.
