Abstract

Combined plastic and paper waste (paper envelopes with plastic window, large envelopes made from paper with plastic air bubble, etc.) are not recyclable by current technologies. The storage is the only viable alternative to disposal, but in this case a series of issues arise by the release of pollutant compounds into the leachate. It has been studied the possibility of using this non-recyclable waste by including it in the structure of composite materials that have applicability in the field of constructions. Current paper presents the results obtained in the analysis of leachates from combined plastic and paper waste before being included in the matrices of composite materials and after applying this recovery process. The comparative analysis of the results highlights the environmental impact of each category of waste. Keywords: combined waste of plastic and paper, composite materials, leaching, environmental impact

Highlights

  • Combined plastic and paper waste (paper envelopes with plastic window, large envelopes made from paper with plastic air bubble, etc.) are not recyclable by current technologies

  • Combined plastic and paper waste are not recyclable by current technologies

  • Sample codes were as follows: P1 - paper envelope with plastic inside; P2 - paper envelope with plastic applied externally; P3 blend of paper envelopes with plastic window; P4 - polypropylene grinding (PP) with 5% combined plastic and paper waste (CW) ; P5 - high density polyethylene (HDPE) grinder with 5% CW; P6 - composite material obtained by injection of HDPE and 5% CW; P7 - composite material obtained by injection of HDPE blend and 15% CW; P8 - composite material obtained by injection of PP mixture and 5% CW; P9 - composite material obtained by injection of PP mixture and 15% CW

Summary

Introduction

Combined plastic and paper waste (paper envelopes with plastic window, large envelopes made from paper with plastic air bubble, etc.) are not recyclable by current technologies. The purpose of this paper is to highlight the reduction of plastic and paper combined waste impact on the environment by their inclusion in composite materials intended for the field of constructions.
