Web-Resol Tudo sobre Limpeza Urbana e Resíduos Sólidos!
Smedlunds Miljösystem intends to turn each bag of dried kitchen rubbish into a quantity of biogas sufficient to keep a car running for 3.2 kilometres (2 miles), Bohusläningen reports. Swedish.com reports that a small residential area in Guldheden has already agreed to try out the method.
"The technology removes around 80 percent of the water contained in household waste, which leaves us with manageable garbage that doesn‘‘t need to be collected too often. And fewer transports mean environmental gains," Lars Smedlund told the newspaper.
Rather than making weekly rounds, a suction truck would need to come to the area just twice a year to collect the rubbish.
"Transport needs are minimized both by the fact that it doesn‘‘t weigh much and can be stored for a long time," said Smedlund.

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...
