However about 15% of the produced waste are still disposed in landfills [1]. The Paperchain project comes up as an innovative demonstrative project that proposes factual applications for different underused PPI waste streams by proving the technical, economic and environmental feasibility on different sectors through implementation of five real scale pilots. [1] CELPA, Boletim Estatístico, (2019) (http://www.celpa.pt/wp-content/uploads/2020/11/BE_2019_WEB.pdf); The Portuguese circular case covers two types of construction materials: pre-cast concrete which is completely replaced by lime ash (CC1a) and bituminous mixture where the fine aggregate and filler is partial replaced by dregs and grits (CC1b). UNIQUE ENVIRONMENTAL TITLE (TUA) ARTICLE 32 OF DECREE LAW Nº 178/2006) LICENSING PROCESS A B C D After production, the precast concrete was discharged inside of columns and beams mould (A). During the discharge process, were installed thermal sensors (B) for strain and thermal internal monitoring in two beams. Once all the beams and columns were dried, SPRAL proceeded with land preparation as well as the installation of bases for columns fit (C). After the installation of the eight columns and the four beams resulted the final pavilion (D). E F G H I CC1a – PRECAST CONCRETE CC1b – ASPHALTIC ROAD The dregs and grits used on CC1b here dried (A) and sieved before the integration on the bituminous mixture. Once achieved the necessary moisture and dimension, the wastes were integrated in bituminous mixture and transported to NVG plant. Before the installation of the bituminous mixtures (reference, integrating dregs and grits) the underlying layer has prepared and cover with tack coat (B). The bituminous mixtures application at NVG facilities were made by Megavia (C). The asphalt preparation and application work was completed in 7 days, in the first week of March 2020 (D). ONE YEAR MONITORING OF ENVIRONMENTAL (LEACHATE) AND TECHNICAL (RESISTANCE) MONITORING Good technical performance No environmental issues (preliminary results) Legal constrains to overcome in favor of demonstrative project (behind paperChain) Raw material Lime Ash (≈ 3 ton) Pre-cast concrete preparation CC1a European Standard: EN 13225 Lime ash Limestone Pre-treatment (dry and sieve) Raw material Dregs & Grits (≈ 6 ton each) Transport Bituminous mixture preparation European Standard: AC 14 Surface CC1b Reference Dregs Grits ACKNOWLEDGMENTS More information of the Project: https://www.paperchain.eu/ LIFE-CYCLE ASSESSMENT PUBLIC DISSEMINATION ECONOMICAL ASSESSEMENT
