For almost 30 years, the Metropolitan Government of Nashville and Davidson County has been relying on one of the more innovative approaches to waste management. Since the early 1970s, the now 1,000 tons per day WTE facility has been the primary energy source for supplying steam and chilled water for a downtown district energy system serving some 39 buildings. A recent review of alternatives has resulted in Metro deciding to close the facility and replace it with a more traditional district energy supply system and at the same time re-engineer its solid waste management programs to include more efficient collection and recycling programs. This paper will present the planning process and analysis that were done; describe the key factors that led to Metro Nashville’s decisions; detail the procurement and development process that has been initiated; and outline the timetable for implementing the decided upon changes. The authors believe this case study will provide insights for other WTE projects that from time to time struggle with peaceful co-existence with other elements of integrated solid waste management. The authors have been serving as advisors to Metro throughout this process. Mr. Gershman has recently been designated by Metro as its overall Project Manager for its District Energy System.

This article analyzes the evolution of integrated solid waste management systems in small and medium cities of the state of Rio de Janeiro. For this purpose, we applied the Modified Solid Waste Management Condition Index (ICGRm), calculated by a spreadsheet with 40 environmental indicators. A field study was carried out to evaluate ten cities in the state of Rio de Janeiro, among twenty already investigated in a survey carried out in the years 2007-2008. The cities were classified as adequate or inadequate according to the ICGRm scores (range from zero to ten points). The comparative evaluation revealed that four cities presented positive evolution, but only slight, while six cities presented worse scores. In the specific case of Brazil, it shows that public managers have not yet given proper priority to solid waste management, although six years have passed since the establishment of the National Solid Waste Policy through Law 12,305/2010. Ten of the cities evaluated reached the level of management considered adequate by the applied method, either in the evaluation in 2007-2008 or 2016, and some showed slight improvement.
