Koudera Town, in Japan‘‘s Hyogo Prefecture, started using toilet paper recycled from discarded confidential documents, including the town‘‘s, for its town hall restrooms in late May 2004. Japan for Sustainability reports that the toilet paper is manufactured by Nishinihon Eizai Co., a Japanese paper manufacturer that has similar contracts with 800 public offices and private companies, mainly in western Japan. Nishinihonn Eizai has had a contract with Koudera town since December 2003.
Classified documents from public offices and other enterprises are usually disposed of by incineration because recycling may lead to leaks of personal information and corporate secrets. The presence of metals such as staples or fasteners and widely fluctuating amounts for collection have also kept this kind of paper from being recycled.
To prevent information leaks, Nishinihon Eizai has introduced equipment that can dissolve confidential documents while still packed in cardboard boxes, and centrifugal separators to remove metal from the dissolved paper. The company started collecting secret documents for recycling into toilet paper in 1992. As the company gained a good reputation among customers, it has been able to collect more used paper, particularly since about 2000.
The company can obtain this used paper at low cost while its customers can reduce expenses for incinerating classified documents. In addition, some customers have successfully cut spending on toilet paper by directly purchasing recycled products from the company

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...
