In order to quantify and compare the environmental impacts caused by several
modern household waste management strategies in the federal state of Baden-Württemberg,
Germany, the Life Cycle Assessment (LCA) cradle-to-grave analysis, which accounts for the
material and energy flows during the life cycle of a product or service, has been applied. In the
case of household wastes, the environmental impacts through out the waste management chain
correspond to the sum of the impacts that arise during the end-of-life operations of each product
that leaves households as waste. The LCA carried out included the evaluation of the direct
impacts arising from household waste management strategies, as well as the benefits obtained
through the substitution of raw material and primary energy sources. The operations evaluated
include the collection and transportation of wastes, material and energetic recovery, anaerobic
digestion, residual waste treatment and final disposal. For the treatment of residual waste,
incineration, mechanical-biological treatment, and mechanical biological stabilization were
modeled, since they represent the state of the art in the Federal Republic of Germany in terms of
waste treatment technologies.

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
