GIS Tools for the Optimization of Solid Waste Transport

Paper review

Objective
The objective of this study is to suggest the most effective routes for collection and transportation of solid wastes of district Cite El Habib.

Background
This case study was carried out in district Cite EL Habib in the city Sfax. This city is the second largest city of Tunisia. People in this city through their wastes in plastic bags in near containers and then it is collected by municipality. This study is carried out to perform a route optimization for the collection and transportation of solid wastes collected from different collection points. In this city the collection and transportation expenses account up to 75% of the total budget of solid waste management. Waste collection is carried out manually and mechanically.

Methodology
Arc GIS network analyst tool was used in the study. Global positioning systems (GPS) was used for tracking the routes of collection. Details of road maps, population density, municipality land use were obtained from google earth. Once all this data was obtained it was processed in to layers such as vector and rasters after that route optimization model was performed in Arc GIS network analysis.

Results
They suggested three scenarios S1, S2,S3 and compared them with existing scenario S0 they perceived that all the suggested routes are more effective than the existing one with respect to fuel consumption, time, work hour, and manpower.

  1. Undoubtedly a molder’s enter is key in aligning initiatives and injection molding machines. Another important feature hottest thongs of our machine park are gas injection expertise machines. Gas injection expertise capabilities by blowing gas, usually nitrogen, into plastic to be able to} mold it into particular shapes. This process permits us to create progressive, more versatile products of superior quality. Gas injection expertise additionally brings a number of|numerous|a variety of} extra advantages, similar to materials savings, decrease price of the products, decrease clamping pressure and a greener manufacturing process. Wittmann Battenfeld is our companion for innovation and technological development in plastic injection molding machines.
