Web-Resol Tudo sobre Limpeza Urbana e Resíduos Sólidos!
In the Bavarian district of Deggendorf, the Donau-Wald waste management administration union (ZAW) have introduced an ‘‘electronic sheriff‘‘ to reduce the amount of contaminants that find their way into the organic waste bin.
Passauer Neue Presse reports that using a detector that is attached to the refuse collection vehicle, it can be ascertained whether or not the bin only contains organic waste. The measuring device is able to detect whether stray materials such as metal bottle tops are present. As part of the pilot scheme, householders will be issued with green and yellow cards: the green card means that the contents of the bin are fine, while the yellow card denotes that there are materials in the bin that do not belong. From November, red cards will be issued to householders who persistently throw away non-organic waste in the green bin. In this case, the bin will not be emptied and the offender will have to find alternative means of disposal.
The pilot scheme is currently running in Deggendorf and the town of Passau. For years the ZAW has been reporting an increase in the amount of contaminants in the organic waste bin, from 1.65% in 1997 to 3.85% between January and May of this year. According to Karl-Heinz Kellermann, director of ZAW, the costs of dealing with contaminated organic waste last year were in the region of EUR150,000. If the new technology proves to be effective, then customers will benefit from the savings in the long run.
The ‘‘electronic sheriff‘‘ costs EUR40,000 and has already been successfully employed in other regions. Once the test phase comes to an end, the ZAW will need to decide whether or not to adopt it permanently

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...
