This paper presents a method for optimizing the household waste collection system supported by Geographical Information System (GIS) tool for the sector 1of district El Bousten of Sfax commune, Tunisia. The ArcGIS Network Analyst based model is applied for the purpose of improving the collection process effectiveness, namely, the household collection bins’ reallocation along with the vehicles’ tour optimization procedure in terms of distance and time. Results indicated a reduction of 25, 83% in route and 21, 5 % in the time spent of collection along with fuel consumption savings. These findings show that GIS based model tends to exhibit significant improvements as to the collection and transportation system, therefore, to its economical and environmental costs.

The One

Separate waste collection and recycling are at the basis of today’s wastemanagement. This helps the reduction of landfilled waste, which aims to reduce soil, water, and airpollution, on the one hand, and to cut down on the depletion of resources for new production, on theother. A large portion of household waste comes from the so-called “widespread waste”, whichincludes packaging waste. Legislation at European and national levels sets specific goals toovercome this problem. Separate waste collection is carried out by municipalities via wasterecycling companies, which set up and operate systems for separate collection. Citizens are at theheart of the efficient functioning of these systems. A separate waste collection system of this kindhas been established in the municipality of Stara Zagora in Bulgaria. The objective of this paper isto present the results of a questionnaire survey of the system’s users to establish their awareness andattitudes regarding the process of separate waste collection. The results can be used to improve thesystem.

New System

Nowadays the usage of source separation waste collection system is essential for all organisations. This paper describes a case of introduction of such a system at a university of applied sciences (UAS) in Tallinn. The project started in September 2015. The main goals of the project were to reduce the number of garbage cans in the UAS, reduce the amount of unsorted household waste and inform the school community about the significance of waste sorting and relevant environmental matters. The first step of the project was to execute a full waste audit in UAS to identify precise waste quantities which occurred on daily basis. During the week the environmental technology students weighed and sorted all the waste in all premises of the UAS. Based on the collected data, the new system comprised of 19 waste collection points with sorting instructions and adequate volume. The total number of garbage cans was reduced by 46% and mixed household garbage cans by 72%. The final step was to analyse the efficiency of the new waste collection arrangements. Results showed that the new system was well accepted and 80–85% of waste was sorted and collected in the new waste collection points.

Cloud Applications

Moving to Industry 4.0 involves the collection of massive amounts of data and the development of big data applications that can ensure a quick data flow between different systems, including massive amounts of data and information collection from smart sensors, and sending them to cloud applications that allow real-time data monitoring and processing. Securing and protecting the transmitted data represents a big issue to be discussed and resolved. In the paper, we propose a new method of data encoding and encryption for cloud applications using PNG format images. The proposed method is described in comparison with one of the classical methods of data encoding and transmission used currently. The paper includes a case study in which the proposed method was used to collect and transmit data from an automated waste collection system. The results show that the proposed method represents a secure, fast and efficient way to send and store the data in the cloud compared to the methods currently used. The proposed method is not limited to being used only in waste management but can be used successfully for any type of manufacturing system from smart factories.
