“…These activities are known to differ according to the location, demographics and nation. Even within the same country, big cities, small cities, suburbs and villages are known to differ in respect to the WM actions [Kayakutlu et al, 2017] In Poland, according to the current legal directives regarding the MWM, participation in an organised WMS has become a priority for all the country's residents. This article analyses the functioning of the WMS in the area of the selected municipality.…”

Waste disposal in landfill sites causes a potential hazard for the human health, as they release substantial amounts of gas, odours and pollutants to the environment. There have been vast reductions in the volume of waste being landfilled in many European countries and a reduction in the number of illegal landfills. The European Parliament's laws obliged the Member States to amend the national waste law; the main objectives of the implemented directives are to create the conditions for the prevention of excessive waste. Directive 2008/98/EC establishes, as a goal for 2020, that waste reuse and recycling reach 50% of the total waste produced. Poland, having joined the European Union, committed itself to implementing many changes related to waste management. The amendment of the law on the maintenance of cleanliness and order in the municipalities imposed new obligations regarding the waste management (WM) on the local government and residents. By adopting a municipal waste management system, the selected municipality made all its residents responsible for their waste. However, the fact of introducing changes does not solve the waste problem. The implementation of EU directives and the development of strategic documents such as the National Waste Management Plan (NWMP) have made a clear change in the WM approach. One of the changes was the establishment of selective collection of municipal selective waste (MSW), with the issue of collecting the waste by the residents being a priority. This work describes the legal context of selective collection of MSW as one of the most effective means of reducing the amount of waste being landfilled.

“…However, urban symbiosis brings not only opportunities but also bottlenecks. One of them is that it requires involvement from various stakeholders possibly holding conflicting objectives, which makes the overall decision-making process less straightforward and more complex (Kayakutlu et al 2017). In this view, other techniques like graph theory (Melese et al 2017) or agent-based modelling (He et al 2017) may be required to model complex decisions in a multi-stakeholder setting.…”

“…The DSM must allow a successful transfer of MSW management practices between counties, while considering local peculiarities and constraints. Extensive work is still required for the development of coherent MSW management solutions in an urban context in the presence of multiple stakeholders and decision factors (Kayakutlu et al 2017). Thus, the focus of this paper is on the development of a novel DSM for MSW recycling that is consistent with this analysis and the hierarchy of MSW management measures defined by (DIRECTIVE 2008/98/EC 2008.…”

The rapid expansion of urban populations and concomitant increase in the generation of municipal solid waste (MSW) exert considerable pressure on the conventional centralized MSW management system and are beginning to exceed disposal capacities. To tackle this issue, the conventional centralized MSW management system is more likely to evolve toward a more decentralized system with smaller capacity waste treatment facilities that are integrated at different levels of the urban environment, e.g., buildings, districts, and municipalities. In addition, MSW can become an important urban resource to address the rising energy consumption through waste-to-energy (WTE) technologies capable of generating electricity, heat, and biogas. This shift toward the combined centralizeddecentralized waste-to-energy management system (WtEMS) requires an adapted decisionsupport methodology (DSM) that can assist decision-makers in analyzing MSW generation across large urban territories and designing optimal long-term WtEMS.The proposed integrated DSM for WtEMS planning relies on: i) an MSW segregation and prediction methodology, ii) an optimization methodology for the deployment of multi-level urban waste infrastructure combining centralized and decentralized facilities, and iii) a multicriterion sustainability framework for WtEMS assessment. The proposed DSM was tested on a case study that was located in Singapore. The proposed WtEMS not only reduced the total operational expenses by about 50%, but also increased revenues from electricity recovery by two times in comparison with the conventional MSW management system. It also allowed more optimal land use (capacity-land fragmentation was reduced by 74.8%) and reduced the size of the required transportation fleet by 15.3% in comparison with the conventional MSW system. The Global Warming Potential (GWP) was improved by about 18.7%.

“…In order to implement the NWMP's guidelines, RWMP is being drafted in each Region which specify the integrated management of all waste generated in their geographical unit according to the objectives and forecasts of the NWMP (Kayakutlu et al, 2017). On this basis and the existing legislation, the RWMP is developed and implemented by the Regional Solid Waste Management Authority.…”

Using an online platform for the improvement of industrial symbiosis and circular economy (in Western Macedonia, Greece)

<p>The part of industrial ecology known as industrial symbiosis engages traditionally separate industries in a collective approach to competitive advantage involving physical exchange of materials, energy, water and by-products (Dounavis et al. 2015, Dounavis et al. 2016, Ravindran and Jaiswal 2016, Kourmentza et al. 2018, Keskisaari and Kärki 2018, Ayadi et al. 2018). The keys to industrial symbiosis are collaboration and the synergistic possibilities offered by geographic proximity. Industrial symbiosis includes initiatives in which two or more industrial entities develop both beneficial relationships and the circular economy (Chowdhury et al. 2018). Since, the symbiosis encourages the sustainable development and promotes the economy growth (de Jesus et al. 2018). This paper presents an online industrial symbiosis and circular economy platform created by a LIFE project (still ongoing) which aims to demonstrate the usefulness of a digital on-line platform at European level for the cataloguing, use and exploitation of industrial waste produced in a local area in order to improve the overall performance of industrial processes and circular economy in a local level. All this will happen both through the increased use of waste within the area itself and by the less dependence on the disposal of waste to be disposed of, taking into account the reduction of used raw materials and the reduction of waste itself. The platform will be created through the European LIFE M3P Project (Material Match Making Platform for the promotion of the use of industrial waste in local networks) which is still on-going and ends at the end of September 2019.</p>
