Harnessing energy from waste
As a subsidiary of Séché Environnement operating under a public service delegation, Alcea Nantes has operated a waste recovery unit serving the greater Nantes area since 2012. Here, we recover industrial and household waste from the region, transforming it into energy.
The facility handles three categories of waste:
- household waste
- non-hazardous waste generated by businesses
- medical waste generated by healthcare establishments and professionals across the region
This potentially infectious medical waste (PIMW) is handled within a specific treatment channel to avoid operators coming into any contact with it.
Alcea endeavors to recover the energy produced by burning this waste as:
- heat – connected to the Centre Loire heat network (87km), the facility generates enough heat to supply the equivalent of 41,000 homes (including apartments, swimming pools, and hospitals), representing 56% of the need served by the network.
- electricity – since 2014, we have been transforming a portion of this energy into electricity using a special turbine. Our waste plays a key role in generating renewable energy as by harnessing this energy source, we become less reliant on fossil energy.
And that is what the circular economy is all about!

Harmoniously combining biodiversity and industrial activity in Alcea's gardens
The Alcea teams take care to provide refuges and habitats essential to the long-term survival of local species (including insects, birds, small mammals), such as bird boxes, insect hotels, shrubbery and green spaces. In partnership with the Ligue de Protection des Oiseaux, we monitor changes in bird, bat and plant populations. Involved in the Sustainable Practices to Protect Nature launched by the Group, we also implement initiatives to raise awareness among our teams (a guide listing the nature walks in the local area, an in-house gazette, and directives to reduce consumption and waste).

Preserving natural resources
In order to preserve natural resources, we make use of rainwater collected in a 450 m3 basin in our processes (for example to clean medical waste containers).

Harnessing the full potential of waste to benefit the local area
Each day, Alcea receives waste from 24 towns around the greater Nantes area. Non-recyclable waste is destroyed so as to recover the metal contained therein, generate energy and protect the environment.
