INTRODUCTION:-Inthe past few decades, solid waste management systems in Europe have involvedcomplex and multifaceted trade-offs among a plethora of technologicalalternatives, economic instruments, and regulatory frameworks. These changes resulted in variousenvironmental, economic, social, and regulatory impacts in waste managementpractices which not only complicate regional policy analysis. Systems engineering models andsystem assessment tools, both of which enrich the analytical framework of wastemanagement.
Consideringsystems analysis models and tools in a synergistic way would certainly provideopportunities to develop better solid waste management strategies leading to conformitywith current standards. Inthe 21st century, the sustainable management of municipal solid waste (MSW)will become necessary at all phases of impact from planning to design, tooperation, and to decommissioning. Suchan orderly evolution allows both waste management industries and governmentagencies to meet common needs of waste management with greatest greenpotential, to recycle materials out of waste streams, to enlarge the renewableenergy supply, to seek for more socially acceptable options, and to preservebiodiversity and natural ecosystems simultaneously.Systemsanalysis techniques have been applied to handle MSW streams through a range ofintegrative methodologies in the last few decades.
A total of five systemengineering models and nine system assessment tools were formally classified inthis field to illuminate the challenges, trends and perspectives.1.systemsengineering models including cost benefit analysis (CBA).
2.system assessment toolsincluding management information system.Systems analysistechniques:- asystem can be a set of related components or sub-systems, which interact witheach other in some way. The properties of a system are defined by the whole of thesub-systems, their characteristics, and their relationships.Ø Systemsengineering models:-system arises from siting facilities, selecting technologies, and comparingmanagement options.
Ø Systems assessment tools:-Most of the time, aftersystems have been created and implemented, it is necessary to evaluate their performanceand consider how improvements could be made.Methodology:-Several types of SWMsystems in European countries can be identified and classified.Ø Wastemanagement systems in European countries: From a life-cycle point of view, an all-inclusiveMSW management system includes all essential operational units from collection,to shipping, to treatment, to recycling, and to disposal. waste managementractices tied to policies, institutional settings, fi nancial mechanisms,technology selection, and stakeholder participation.Findings:- MSW management is normally seenas a major decision making issue with respect to sustainable development in alllocal communities of the EU.This evaluatesthe present situation of SWM systems in the EU countries in terms of wasteprocessing systems, policy and decision making issues.The southern countriesrequire more measures then the developed northern countries of Euroup.
