Automated sorting system for advanced waste disposal

Objective



Objectives and content
Steadily increasing volumes of garbage and waste, exhaustable resources, and the increasing scarcity of landfill space call for economically and ecologically sensible solutions of the problems in all areas of waste disposal. Because the input material from the several collections is not pure on arrival, it has to be divided into different fractions manually at sorting lines in waste disposal plants. The optimum procedure is then first to separate the critical fraction of special refuse from the complete input material in order to pass it on to proper disposal or rather to corresponding recycling processes. The next step is to select as many valuable materials or different recyclable fractions as possible.
Present day waste sorting systems are mostly working manually ("handpicking") with a proceeding rough division by mechanical systems into two to three fractions. For reasons of profitability and the necessary humanization of workplaces, the aim in all areas of waste disposal must be the highest possible degree of automation of the sorting processes. Within the framework of this project, the aim is therefore to bring forward the plants in the area of demolition waste from manual picking to fully automated processes considering the arising amounts of waste in the European countries.
Here, special requirements must met the modular structure of the identification systems and of the handling techniques. This is the only way to guarantee flexible application also in other areas of the waste disposal industry as well as adaptability to different input materials, batches and changed boundary conditions. It has already become clear that such a sorting system should not be seen as detached from the total facility since the success of fully automated sorting considerably depends on the preparatory techniques of pretreatment and the separation of the material achieved this way. Only properly separated material offers the basic requirements for optimum identification and gripping of the objects and thus the chance of a fully automated solution of the sorting problems.
The result of this project will be a prototype sorting system realized in an application of demolition waste utilisation and able to detect and separate automatically valuable fractions from the mixed material stream. Additionally, the project will provide enough data for a transfer of the results to other sorting applications.
