INTRODUCTION

Integrated Solid Waste Management (ISWM) is a comprehensive waste reduction, recycling, composting, and disposal program.

ISWM involves evaluating local needs and conditions, and then selecting and combining the most appropriate waste management activities for those conditions.

The major ISWM activities are waste reduction, recycling and composting, and combustion and disposal in properly designed, constructed, and managed landfills.

What is Integrated Solid Waste Management?

Why Is Solid Waste Management a Challenge?

Waste generation increases with population expansion and economic development.

Uncontrolled dumping and improper waste handling causes a variety of problems, including

1. Ground water contamination

2. Attracting insects and rodents

3. Flooding due to blocked drainage canals

PROJECT DETAILS

The General Algebraic Modeling System (GAMS) is specifically designed for modeling linear, nonlinear and mixed integer optimization problems.

GAMS is especially useful for handling large, complex, one-of-a-kind problems which may require many revisions to establish an accurate model.

GAMS handles dynamic models involving time sequences, lags and leads and treatment of temporal endpoints.

GAM Models:

GAMS supports the following basic model:

LP Linear Programming

MIP Mixed-Integer Programming

NLP Non-Linear Programming

MPECMathematical Programs with Equilibrium Constraints

CNSConstrained Nonlinear Systems

DNLPNon-Linear Programming with Discontinuous Derivatives

MINLPMixed-Integer Non-Linear Programming

QCPQuadratically Constrained Programs

MIQCPMixed Integer Quadratic ally Constrained Programs

Purpose

The purpose of the model is

To assist in selecting strategies that minimize the cost of waste collection, transportation, operation, and disposal.

To extend earlier solid waste management models by considering a relatively new type of waste disposal, in addition to other more standard disposal methods already included in a number of optimizationmodels.

Depending on climatic, demographic, social and economic factors, composting facilities can divert 10-35% of the residential solid wastestream from the landfill alternative.

To includes the revenues produced by the sale of composting material generated by the facility.

To derive an overall solid waste strategy for a community, including the allocation of solid waste to several alternative modes of treatment, such as recycling, incineration, landfill, and composting.

To identify the optimum sites for a combination of these facilities.
