Waste heat recovery from exhaust gasses with high particle or chemical content addresses an opportunity into a very specific market with hundreds of thousands of potential users, where the bigger segment is represented by the steel making sector but many other industries can benefit from this technology.

One goal of the LIFE HI4S project is indeed to expand its replicability, focusing on similar off-gas streams processes typical of energy intensive industries such as ceramic, foundry, glass, cement production, where most of the energy is used as heat.

LIFE HI4S project technology will meet stakeholders needs of energy efficiency and savings by providing effective solutions to recover great amount of waste heat at reasonable costs.

Proper identification, engagement and needs understanding of any stakeholders will be a key factor for the success and the exploitation of the LIFE HI4S project.

Stakeholders’ involvement therefore will be present from the very first stage of the project.


Main stakeholders and first industry involved, as technology user and as thermal energy storage material provider. The sector interest goes beyond the heat recovery technologies since the project also address the use of steel wastage.

The sector includes steel making companies, relevant associations and clusters.


The results of the project could be relevant for any energy intensive industry where energy input used to produce heat led to common heat waste along the process.

EIIs stakeholders are mainly from foundry, ceramic, cement, glass and chemicals manufacturing sectors.


Engineering companies could be important stakeholders in order to implement LIFE HI4S project as a cost-effective solution to improve industrial processes or to design new production plants.


LIFE HI4S project solution can lead to energy efficiency improvements, potential savings and source of income for ESE new production plants.


The project goal is to ensure collaborations and potential application and replicability also outside the steel sector.

The priority will be to engage with European sectors associations, local energy and environmental agencies, supply chain organizations to build connections and pilot projects.


One of the main goals of the LIFE HI4S project is to develop a technology that could be included among the Best Available Technologies (BAT) for iron and steel production, and to be considered a part of a European list of clean technologies that could benefit from regulation, environmental funding or tax reduction.


LIFE HI4S project solution can lead The development and exploitation of LIFE HI4S technology will address waste heat reuse in the steel production and energy intensive industries that are usually perceived by the general public as high polluting sectors in terms of emissions, noises, fumes and dirtiness.

LIFE HI4S project will lead indirectly to pollution decrease thanks to a reduction of energy consumption, and thus to the related emissions, during the production process.
