Web-Resol Tudo sobre Limpeza Urbana e Resíduos Sólidos!
Tottori Ecotown 2020, an incorporated nonprofit organization in Tottori Prefecture, conducted a two-month pilot project (Dec. 2004 – Jan. 2005) which provided transportation services using eco-friendly shared bus-taxis powered by cooking-oil waste collected from households. Japan for Sustainability reports that the bus, called Inaba EcoLimo Waiwai Go-Go, made two round trips a day between Wakaba-dai (location of the Tottori University of Environmental Studies) to Karo via Tottori University, a route not covered by public transportation.
Passengers can ride without charge if they obtain membership in the "Be Nice to the Earth Club." Membership in this club is awarded to people who bring used cooking oil to collection sites at elementary schools, and to bus passengers who promise to perform eco-friendly activities such as volunteering for cleanups and buying green products at eco-friendly shops.
The NPO aims to set up a shared bus-taxi company co-organized by university students, residents and local businesses. The company will own buses powered by biodiesel fuel refined from used cooking oil, and run them in areas with inadequate public transportation. It hopes that local residents will eventually use this eco-bus instead of their private cars, reducing total use of fossil fuel use in the area. It also hopes that the bus service will encourage interaction between passengers

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...
