The presented study describes the challenges that is performed on the basis of the EU-Georgia Association Agreement in the waste management sector of Georgia. Georgia set ambitious targets for waste recycling. The Vision of the Waste Management in Georgia is: "Georgia to become a preventing and recycling society". It would be necessary to establish waste separation systems in immediate proximity to paper, plastic, glass and metal waste sources. So, the enterprises must be to be able to do more recycling as much as possible. Waste recycling is that sector of business, which must be developed rapidly, in order to cover at least those minimal needs, which the country's waste management sector is being faced today. The planned measures will result in significant challenges of the country's local authorities, universities, business and the whole society in the near future. With the aim of supporting and studying the current situation in waste separation and recycling within the framework of the project "Supporting Small and Medium Enterprises", Imereti Scientists Union SPECTRI try to collaborating all stakeholders based on the Quadruple Helix Model. For identifying the problems and needs of the recycling was performed a survey of business entrepreneurs involved in this field, to study the prospects of development of recycling and demonstrate effective mechanisms for promoting mutual cooperation with governmental and non-governmental sectors. ; The presented study describes the challenges that is performed on the basis of the EU-Georgia Association Agreement in the waste management sector of Georgia.

For decades, significant work has been conducted regarding plastic waste by dealing with rejected materials in waste masses through their accumulation, sorting and recycling. Important political and technical challenges are involved, especially with respect to landfilled waste. Plastic is popular and, notwithstanding decrease policies, it will remain a material widely used in most economic sectors. However, questions of plastic waste recycling in the contemporary world cannot be solved without knowing the material, which can be achieved by careful sampling, analysis and quantification. Plastic is heterogeneous, but usually all plastic waste is jointly handled for recycling and incineration. Separation before processing waste through the analytical approach must be applied. Modern landfill mining and site clean-up projects in contemporary waste management systems require comprehensive material studies ranging from the macro-characterization of waste masses to a more detailed analysis of hazardous constituents and properties from an energy calorific standpoint&mdash ; where, among other methods, thermogravimetric research coupled with life cycle assessment (LCA) and economic assessment is highly welcomed.

For the next century to come, one of the biggest challenges is to provide the mankind with relevant and sufficient resources. Recovery of secondary resources plays a significant role. Industrial processes developed to regain minerals for commodity production in a circular economy become ever more important in the European Union and worldwide. Landfill mining (LFM) constitutes an important technological toolset of processes that regain resources and redistribute them with an accompanying reduction of hazardous influence of environmental contamination and other threats for human health hidden in former dump sites and landfills. This review paper is devoted to LFM problems, historical development and driving paradigms of LFM from 'classical hunting for valuables' to 'perspective in ecosystem revitalization'. The main goal is to provide a description of historical experience and link it to more advanced concept of a circular economy. The challenge is to adapt the existing knowledge to make decisions in accordance with both, economic feasibility and ecosystems revitalization aspects. (C) 2016 Elsevier B.V. All rights reserved.
