Getting rid of waste, fuelling ships, and at the same time using residual energy to fuel a desalinator and produce water to irrigate fields – too good to be true?.
AGI reports that the proposal was made by Industriale Italia, a Neapolitan company that forecasts the use of an international patent for the construction of eco-friendly ships of various dimensions according to the quantity of waste it is able to receive and use (hundreds of tons a day) with a revolutionary system of energy recovery from solid urban and special waste.
In a report made by the company, it is emphasised that this technology as a perfect adaptability to working in the marine environment, both on ships as well as floating platforms, and can treat waste with a moisture ratio that does not exceed 20-22 per cent, with emissions lower than those set by law. There is also a decrease in ash production.
The design and construction of a multi-service ecological ship, moreover, would reduce costs connected to waste activities (gathering, transportation, disposal). There would also be a local monitoring service for the local administration for aspects concerning management of services and environmental impact. The project is also said to produce freshwater at no cost.

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...
