**6. Conclusions**

The present LCI modeling of municipal solid waste management (MSWM) systems in Kosodrza, community of Ostrów, Poland case study was given according to PN-EN ISO 14040.

This study is focused on the operational results recorded in 2015, as defined in the goal and scope.

It should be noted that LCI work was performed using the secondary data obtained from integrated permit legislated for waste landfill in Kosodrza, community of Ostrów in Poland.

The results may be useful for MSWM in Poland. In the methodological approach regarding databases, boundaries were transparent and fully documented. Moreover, the results of this study can help MSW management authorities and practitioners to solve environmental and technical aspects and decision makers to understand the nature of the LCA. In addition to LCI, these data can be used to assess life cycle impact assessment (LCIA) as the next step of LCA methodology, and finally, full LCA should be conducted. The LCIA provides the analysis of collected data to evaluate contributions to various environmental impact categories. The final LCA of a modern MSW landfill should include the uncertainty of waste compositions.

 The LCI study allows to identify and understand LCA approach from the view of further research work with a view to reduce the negative impact of *waste on* the environment as well as to reduce the negative impacts on ecosystems, on human health or on natural resources.

However this study has examined a case at the country level. This case study could be used by other domestic and international LCA studies of solid waste management systems.

The results obtained from this study can move the LCI on the waste management process one step forward and will assist in developing environmental awareness in the development of the National Waste Plan.
