Web-Resol Tudo sobre Limpeza Urbana e Resíduos Sólidos!
The Woodlawn Bioreactor has now (April 2007) been in operation 2.5 years and
has gone through a variety of operational issues which have generated management responses to
ensure that the objectives of the facility, namely the orderly disposal of 480,000 t of waste per
annum; the expected generation of energy and, finally, the avoidance of environmental impacts
is achieved. This paper describes the issues encountered which include initial waste saturation
with acid sulfate rich runoff and groundwater inflows; H2S generated OH&S issues, the
competition of sulfur reducing bacteria with methanogens and the maintenance of effective gas
harvesting, gas generation and monitoring. During this process a great deal has been learned
about the processes within the waste mass and how these can be controlled and utilized. An
essential element of the learning process has been and will continue to be, the focus of
monitoring on parameters which reflect the processes which are sought to be managed to achieve
optimal benefit

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...
