« Warmth from Waste : potentiel de production de chaleur à partir des déchets | «Réseaux de Chaleur et Territoires

Trois associations européennes impliquées dans le domaine de l’énergie (CEWEP, ESWET et Euroheat&Power) publient, à travers la plate-forme DHC+, un livre blanc sur le potentiel de développement conjoint des réseaux de chaleur et de la valorisation énergétique des déchets sous forme de chaleur, au niveau européen.

En France, le projet de loi de transition énergétique prévoit de renforcer la valorisation énergétique des déchets non valorisables sous forme de matière. En Ile-de-France, l’ADEME et ses partenaires placent la récupération de chaleur fatale (incluant donc la chaleur issue des déchets) en source prioritaire à mobiliser, avant d’examiner les sources renouvelables comme la géothermie ou la biomasse. Il s’agit en effet d’une source d’énergie locale, qui est produite de toute façon, et donc perdue si on ne l’exploite pas.

Executive summary

The Background Paper for project development on District Energy from Waste, created by three associations active in the energy field (CEWEP, ESWET and Euroheat & Power through the DHC+ Technology Platform), aims to serve as a basis for any future European or national project development, in particular under the Horizon 2020 Framework Programme.

The Paper identifies the potential for enhancing the collaboration between the District Heating and Cooling (DHC) sector and the Waste-to-Energy (WtE) sector across Europe. The results are presented in the form of a list of activities that could be developed at the European level along with their respective potential impact.

In 2009 the European Council set the objective for the EU to decarbonise its energy system by at least 80% below the 1990 level by 2050 without affecting general economic growth. The Directive on Energy from Renewable Sources (RES Directive) sets a 20% target for renewable energy by 2020. Current EU targets on waste will be revised during 2014 and are likely to become more ambitious: the amount of waste sent to landfill will be reduced and the demand for more sustainable waste treatment will increase. A scenario which could help to fulfil all these targets is the increased exploitation of synergy between WtE and DHC.

Waste represents a local, cost effective, secure and sustainable energy source which is already used in some DHC systems, allowing them to deliver affordable energy and reducing primary energy consumption.
