Web-Resol Tudo sobre Limpeza Urbana e Resíduos Sólidos!
The Board of Education of Masuda City, Shimane Prefecture in western Japan, has launched a project to recycle milk cartons from school lunches at elementary and junior high schools in the city. Japan for Sustainability reports that the project, started in September 2004, aims to raise schoolchildren‘‘s awareness about the need to establish a recycling-based society.
A total of 4,700 two-hundred-cc milk cartons are consumed every week (Monday to Friday) at the 27 elementary and junior high schools in the city. Before the recycling project began, these cartons were collected by the dairies for incineration. However, Shimane prefecture issued a notice calling for a halt to milk carton collection by dairies, so the board decided to embark on this project. In its six elementary schools having 200 or more students, forth, fifth and sixth graders have started recycling. In its 10 junior high schools and 11 elementary schools having fewer than 200 students, all students have been recycling. The board plans to extend the project to all students in all 27 schools in fiscal 2005.
Students rinse, cut open and dry the used cartons. Each school then bundles the cartons in the school kitchen. They are sent to a used-paper collecting wholesaler in Hiroshima Prefecture after going through intermediate treatment by a private recycler. Paper manufacturers in Ehime Prefecture or Tokushima Prefecture, western Japan, recycle the cartons into toilet paper.
When the project started, the students learned why they should collect used milk cartons and how they are recycled. Now the students seem to be pleased to participate in the activity

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...
