DuCoop invests in sustainable technologies for the Nieuwe Dokken, the new circular districts in Ghent. The cooperative DuCoop provides systems for decentralized water sanitation with water re-use, 4^thgeneration district heating and smart energy management. The company contributes to the climate ambitions of the city of Ghent, by closing the loops on water, energy and nutrients.

Calefa is a Finnish company specialized in the reuse of residual heat from industry by redirecting the excess heat from industrial processes either to the customer company’s own use or to the district heating network, instead of wasting it as condensed water or air.

The overall objective of the project is the "smart" exploitation of Petroleum Refinery Sludges (PRS) produced by the Refinery of Motor Oil Hellas in Corinth (Greece).

With FarmacoAmico, CiboAmico and Cambia il Finale, the HERA has moved beyond its core business to actively prevent medicines, food and bulky goods from becoming waste.

REDEL is an energy provider in Italy. Its activities comprise decommissioning outdated energy installations. The PVC Upcycling project aims to initiate a circular model for reclaiming resources by:

• de-manufacturing: recovering the PVC of electric cables coming from decommissioned energy plants;
• re-manufacturing: recycling of the same PVC in products.

VertECO consists of a vertical ecosystem (vertical constructed wetland) treating greywater from handwash basins, showers, and laundries.

To support ENEL’s transition towards a circular economy, its Global Procurement department aims to achieve a detailed understanding of the flows of its materials (components, environmental impact and recyclability of final products) through the EDP project, which involves its suppliers' commitment.

Enel is a prominent energy actor in Italy. As a result of its investment in renewable energy, 23 obsolete thermoelectric power plants and one mining area are to be decommissioned.
The Futur-E project aims to reconvert these outdated plants into local facilities satisfying criteria of innovation, social, environmental and economic sustainability.

Genesis Biopartner has built a plant for the co-generation of thermal energy (heat) and mechanical energy (electricity) from biogas in Romania.

Stimergy by using a liquid cooling and heat recovery system in server rooms or by decentralising its servers in "digital boilers" located in residential and public buildings recycles heat from data servers to water heating systems. Thanks to its liquid heat recovery system, Stimergy both reduces energy waste of servers and energy needs of water heating systems.
