 INTRODUCTION:-

In
the past few decades, solid waste management systems in Europe have involved
complex and multifaceted trade-offs among a plethora of technological
alternatives, economic instruments, and regulatory frameworks. These changes resulted in various
environmental, economic, social, and regulatory impacts in waste management
practices which not only complicate regional policy analysis. Systems engineering models and
system assessment tools, both of which enrich the analytical framework of waste
management. Considering
systems analysis models and tools in a synergistic way would certainly provide
opportunities to develop better solid waste management strategies leading to conformity
with current standards. In
the 21st century, the sustainable management of municipal solid waste (MSW)
will become necessary at all phases of impact from planning to design, to
operation, and to decommissioning. Such
an orderly evolution allows both waste management industries and government
agencies to meet common needs of waste management with greatest green
potential, to recycle materials out of waste streams, to enlarge the renewable
energy supply, to seek for more socially acceptable options, and to preserve
biodiversity and natural ecosystems simultaneously.

Systems
analysis techniques have been applied to handle MSW streams through a range of
integrative methodologies in the last few decades. A total of five system
engineering models and nine system assessment tools were formally classified in
this field to illuminate the challenges, trends and perspectives.

1.systems
engineering models including cost benefit analysis (CBA).

2.
system assessment tools
including management information system.

Systems analysis
techniques:- a
system can be a set of related components or sub-systems, which interact with
each other in some way. The properties of a system are defined by the whole of the
sub-systems, their characteristics, and their relationships.

Ø  Systems
engineering models:-
system arises from siting facilities, selecting technologies, and comparing
management options.

Ø 
Systems assessment tools:-
Most of the time, after
systems have been created and implemented, it is necessary to evaluate their performance
and consider how improvements could be made.

Methodology:-
Several types of SWM
systems in European countries can be identified and classified.

Ø  Waste
management systems in European countries: From a life-cycle point of view, an all-inclusive
MSW management system includes all essential operational units from collection,
to shipping, to treatment, to recycling, and to disposal. waste management
ractices tied to policies, institutional settings, fi nancial mechanisms,
technology selection, and stakeholder participation.

Findings:-

               MSW management is normally seen
as a major decision making issue with respect to sustainable development in all
local communities of the EU.This evaluates
the present situation of SWM systems in the EU countries in terms of waste
processing systems, policy and decision making issues.The southern countries
require more measures then the developed northern countries of Euroup.
