The main objective of the project is to demonstrate that artificial lightweight aggregates (*) can be obtained from the mix of WWTP sludge and sludge from the natural aggregates extraction process for application in construction/infrastructure and gardening/ horticulture.
The specific objectives of the project are as follows:
• To develop an alternative sludge management process that facilitates recovery, in accordance with European Commission environmental policies (Directive 2008/98/EC. Article 4.1.b).
• To design and construct a pilot plant for the manufacture of artificial lightweight aggregates.
• To establish the technological and environmental parameters necessary for the new products, in accordance with applicable Spanish and European legislation.
• To validate project results technologically and environmentally, through lifecycle analysis of the products obtained and their use in the applications envisaged within the framework of the project.
• To promote the use of the artificial lightweight aggregates produced as a result of sludge recovery.
(*) Light aggregates are natural or artificial products with a density of less than 1200 kg/m 3 , which are used in multiple applications: to obtain lightweight construction elements and/or insulating materials, gardening/horticulture etc.
The project comprises 11 main tasks or actions. One of these is a preparatory action; two are associated with the monitoring of technical, environmental and socioeconomic indicators; one is related to dissemination and communication; one relates to management and coordination, and the six remaining actions are associated with technical areas.
