Production of waste follows mankind along its history, but population growth, the culture of consumption and disposable items have led the problems to critical levels. Waste has become a global problem, and there is no simple solution to solve it. All nations are involved and developing countries face hard and costly decisions in their transition periods. Many have so far misdirected the collected waste, generating health and public sanitation problems, which must be urgently addressed and solved by municipal authorities to assure proper waste processing, eliminating dumps and irregular landfills. The purpose of the work was to investigate practical aspects and feasibility of waste processing centers (WPC) with power generation when replacing dumps and landfills. The study was carried with 645 municipalities and a population of 44 million inhabitants. Results show that dumps and landfills require lower investments but have increasing levels of operational and post-shut down maintenance costs, besides sanitation and environmental problems. Concerning financial performance, public management, space, health and sanitation criteria, WPC plants show better results, provided emissions control systems are available and comply with standards in force. Technical, economic, social and environmental aspects can be better managed and they offer better results than dumps and landfills.
Following the presentation, participants will be able to develop a better understanding on how dumpsites and landfills can be replaced by waste processing centers, with advantages in developing countries and emerging economies.
