Municipal Waste Management

Summary The article discusses the transformation of the municipal waste management sector in Poland, taking place during 2011- 2013, upon the case study of the Świętokrzyskie Region. The pivotal assumptions of the new model of municipal waste management in Poland are: the change of the owner of municipal waste that became communities, the improvement of the municipal waste collection, transportation and processing, and finally regionalization that means the division of the territory of Poland into municipal waste management regions. The research conducted among local authorities of the Świętokrzyskie Region has revealed that the system solutions applied in the field of municipal waste management, being currently implemented in Poland, though they are not free from socio-economic threats, lead to the fulfilment of the waste hierarchy, including the increasing levels of recycling and the reduction of bio-waste disposal.

Selective Collection

Social and economic changes make it necessary to put in a great deal of conscious effort to shift towards a closed-loop economy, where waste provides a source of raw materials. The low level of selective collection of municipal waste poses a challenge in many countries, including Poland. One of the major causes of the problems in Poland lies in the fact that waste collection points (WCPs) do not have adequate waste containers. The paper aims to put forward a proposal to improve the operation of WCPs. Seeking for new solutions, it is necessary to account for the conditions under which the bodies responsible for waste management take their decisions. They have to comply with the legislation in force, and at the same time, choose the options that generate the lowest costs. The study concerned a typical residential district with housing in multi-family buildings. For two fill rate variants and four emptying schedules, the number of above-ground containers was calculated. Two variants: for above-ground containers (variant I) and for semi-underground containers (variant II), were compared in terms of operating costs and investment outlays. The proposed increase in the number of above-ground containers, and additionally providing semi-underground containers, will contribute to increased engagement of the local community in the selective collection of waste.

Proposed Model

PurposeWaste production and related environmental problems have caused urban services management many problems in collecting, transporting and disposal of waste. Since collecting and transporting waste are important parts of waste management budget, it is necessary to apply an appropriate method to reduce costs of collection. The aim of this study is to design a new model for urban waste collection vehicle routing problem with time windows and energy generating from waste.Design/methodology/approachA multiobjective model is presented with the objectives of minimizing cost of waste collection, reducing emissions from environmental pollutants and increasing income of recycles trade and energy recovery. Concerning the complexity of the model and its inability to solve large-scale problems, hyperactive genetic algorithms and multiple objective particle swarm optimization are applied.FindingsThe proposed model not only affects costs and income but also reduces the emissions of environmental pollutants. To solve the formulated model, multitarget approaches are applied on the processing site of Kermanshah city as a case study. The solutions of these algorithms and the exact method of partial constraints are compared and the outcomes are verified by numerical analysis by solving various examples in small, medium and large scales. The proposed model helps to collect urban wastes in the shortest possible time in addition to reducing the total cost, revenues from the sale of recycled materials and energy generation.Research limitations/implicationsWaste collection is related to VRP issue. Considering the environmental requirements in waste management, the concept of green supply chain is approached. This study provides a better understanding of urban waste management by examining various articles and combining economic and environmental dimensions. Waste management with a green approach and energy production from disposable waste involves many common stakeholders.Practical implicationsThis study suggests that proper waste management can generate revenue from municipal waste. Moreover, it reduces cost of collecting and emission of environmental pollutants. These findings could motivate companies to waste management with a sustainable approach.Originality/valueThe proposed model boosts the current understanding of the waste management and energy generation of waste. The paper adds additional values by unveiling some key future research directions. This guidance may demonstrate possible existing and unexplored gaps so that researchers can direct future research to develop new processes.

Abstract The paper presents a review of legal conditions regarding the process of municipal waste collection. An analysis of systems and solutions for the management and monitoring of a fleet of vehicles that can be used in the operation of means of transport during the implementation of the municipal waste process was carried out. The paper presents a coherent concept of ICT system for the optimization of the municipal waste collection process in a small-sized municipality. The proposed system can be used by companies responsible for waste collection, transport and service companies participating in the waste collection process.

The paper presents a coherent concept of ICT system for the optimization of the municipal waste collection process in a small-sized municipality. The proposed system can be used by companies responsible for waste collection, transport and service companies participating in the waste collection process. By basing the system on commonly available elements and services (Internet, GSM and GPS), its installation and operation is fast, simple and does not require large financial outlays.

In the present article is shown the use of Maple program for processing of data describing the position of municipal waste sources and topology of collecting area. The data are further processed through the use of graph theory algorithms, which enable creation of collection round proposal. In this case study is described method of waste pick-up solution in a certain village of approx. 1,600 inhabitants and built-up area of approx. 30 hectares. Village has approx. 11.5 kilometers of ride able routes, with approx. 1 kilometer without waste source. The first part shows topology of the village in light of location of waste sources and capacity of the routes. In the second part are topological data converted into data that can be processed by use of the Graph Theory and the correspondent graph is shown. Optimizing collection route in a certain graph means to find the Euler circle. However, this circle can be constructed only on condition that all the vertices of the graph are of an even degree. Practically this means that is necessary to introduce auxiliary edges – paths that will be passed twice. These paths will connect vertices with odd values. The optimal solution then requires that the total length of the inserted edges was minimal possible, which corresponds to the minimum pairing method. As it is a problem of exponential complexity, it is necessary to make some simplifications. These simplifications are depicted graphically and the results are displayed in the conclusion. The resulting graph with embedded auxiliary edges can be used as a basic decision making material for creation of real collection round that respects local limitations such as one way streets or streets where is the waste collection is not possible from both sides at the same time.

The annual amount of cemetery waste in Wrocław does not exceed 1% of generated municipal waste. The largest amount of cemetery waste is generated in autumn months. For the Osobowicki cemetery, the total volume of containers for selective waste collection has doubled since 2013 and now constitutes 49% of the total volume of containers. Research of the content of selected waste containers revealed the segregation of glass, plastics and biodegradable waste in the range from 81% to 92%. For the St. Lawrence cemetery the volume of containers for selective waste collection constitutes only 6% of the total volume of containers there. Despite these difficulties, the degree of separation of glass and plastics is very high (from 89% to 94%). Increase of the volume of containers for biodegradable waste would reduce the high share of green fraction (from 22% to 38%) in non-biodegradable waste containers.
