This document presents the results and conclusions of research which was performed within the scope of Task 3.2 - Sustainable road construction processes that include recycling of materials and use of industrial by-products, which is part of WP 3: IMPROVEMENT OF PAVEMENT STRUCTURE. It deals with the applicability of two types of alternative materials in road construction: firstly, aggregate from steel slag in wearing asphalt layers, and, secondly, aggregate from crushed building rubble in unbound layers.

A device and process for the remediation of water from small biological treatment plants. The invention envisages a remediation device for water remediation, which is connected to the outflow pipe of a small biological treatment plant (SBWTP), and connected to a water supply system for the consumers, consisting of a nano-remediation unit, oxidation units, and ion-exchange and filtration units. The process of water remediation is also envisaged, which leads to the purification of water to the quality of drinking water, the process comprising the steps of nano-remediation with zero-valent iron nanoparticles (nZVI), purification with oxidizing agents, ion-exchange purification and filtration on granular activated carbon. Finally, remediated water is suitable for all secondary human needs and for use in industry, for example concrete making.
