Nowadays industrial companies are getting more and more aware of the fact that a huge amount of the energy consumed every year goes unused and lost in the form of waste heat. Despite the fact that awareness is raising, incentives are available and that waste heat recovery technologies are generally mature and market-ready, heat recovery measures are still unimplemented at industrial level, mainly due to non-technological barriers, and in particular to the lack of reliable data related to heat consumption and waste heat recovery potentials, as well as to types, costs and benefits of heat recovery practices. The aim of this work is to fill such informational gap for the textile sector, providing a knowledge base elaborated on the basis of real industrial data gathered via a massive survey, and allowing further elaborations from the authors and academics. ENEA, the Italian National Agency for New Technologies, Energy and Sustainable Economic development, has in fact seized the opportunity to gather a relevant amount of data related to heat consumption, uses, potentials and recovery practices on the second deadline imposed by the Italian Legislative Decree n°102 of the July 4, 2014, which established periodic mandatory energy audits for large and energy intensive enterprises. Methodology and main results of data analysis are presented, providing a solid basis for both companies willing to identify and evaluate potential heat recovery opportunities for their processes, thus enabling knowledge transfer and practices sharing, and academics and policy makers willing to estimate recovery potentials. Consumption data for the textile sector are presented together with the quantification of main heat uses, allowing the identification of most relevant sub-sectors in terms of waste heat potential; heat recovery practices described in the energy audits are then analysed and characterized from a technical and economic point of view.

Abstract
Nowadays industrial companies are getting more and more aware of the fact that a huge amount of the energy consumed every year goes unused and lost in the form of waste heat. Despite the fact that awareness is raising, incentives are available and that waste heat recovery technologies are generally mature and market-ready, heat recovery measures are still unimplemented at industrial level, mainly due to non-technological barriers, and in particular to the lack of reliable data related to heat consumption and waste heat recovery potentials, as well as to types, costs and benefits of heat recovery practices. The aim of this work is to fill such informational gap for the textile sector, providing a knowledge base elaborated on the basis of real industrial data gathered via a massive survey, and allowing further elaborations from the authors and academics. ENEA, the Italian National Agency for New Technologies, Energy and Sustainable Economic development, has in fact seized the opportunity to gather a relevant amount of data related to heat consumption, uses, potentials and recovery practices on the second deadline imposed by the Italian Legislative Decree n°102 of the July 4, 2014, which established periodic mandatory energy audits for large and energy intensive enterprises. Methodology and main results of data analysis are presented, providing a solid basis for both companies willing to identify and evaluate potential heat recovery opportunities for their processes, thus enabling knowledge transfer and practices sharing, and academics and policy makers willing to estimate recovery potentials. Consumption data for the textile sector are presented together with the quantification of main heat uses, allowing the identification of most relevant sub-sectors in terms of waste heat potential; heat recovery practices described in the energy audits are then analysed and characterized from a technical and economic point of view.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
