Measures for the prevention, recycling and elimination of waste
As major producers and users of building materials, the construction businesses of the Bouygues group operate reclaiming and recycling policies along with an eco-design policy aiming to manage this whole issue throughout the life cycle of products, and to optimise the use of building materials. The media and telecoms businesses produce waste electrical and electronic equipment (WEEE) and take appropriate action to collect and reuse these goods.
In France, the Bouygues group as a whole has improved the processing of its waste electrical and electronic equipment or WEEE (CPUs, laptops, screens, printers and servers) by outsourcing the entire task to ATF Gaia, a disability-friendly company, since 2010. Since the start of the contract, this initiative has collected 58,314 items of equipment (including 14,907 between October 2012 and September 2013). In total, 38% of the 526 tonnes of collected waste equipment was destroyed and 62% reused. In environmental terms, this has saved on 7,092 tonnes of CO2 equivalent and 21.5 million of litres of water since 2010.
Measures for the prevention, recycling and elimination of waste are handled by Bouygues Construction through its Ecosite policy.
Bouygues Construction has also set up a Waste committee that brings together experts from all entities with a view to designing a comprehensive strategy for waste recycling.
Additionally, schemes for reducing worksite waste, especially in civil works, have been put in place. Excavated debris is reused for making concrete, fill or for environmental site rehabilitation. These new procedures can reduce the volume of spoil produced on a worksite by as much as 95%.
For residential developments that are HQE® certified and for all of Bouygues Immobilier’s commercial property developments,
the Clean Worksite charter makes waste recycling mandatory, notably with the help of a waste management plan.
Recycling used electrical and electronic equipment is a major challenge facing Bouygues Telecom.
Reuse is given priority whenever possible, thus lengthening the useful lives of products and equipment. Bouygues Telecom has introduced procedures for controlling channels for recycling telecommunications hardware, by which equipment that has reached the end of its useful life can be put to the best possible use. Bouygues Telecom offers customers a handset recovery service through its stores, on its website and on the B&YOU website. Such handsets are either resold or recycled. After collection, handsets are sorted, tested and wiped of personal data by social enterprises. Handsets not in working order are recycled by specialists. The rest are repackaged and sold on.
Colas, a major producer and a significant user of building materials, has introduced a “recycled materials” indicator.
It measures Colas’ efforts in transforming waste into building materials. Recycling helps to reduce the extraction of aggregates (and hence the opening of new quarries) and the amount of landfill. In 2013, Colas recovered and recycled more than 11 million tonnes of materials, representing 13% of its total aggregate production, equivalent to the average output from 33 Colas quarries 3 more than in 2012. The tonnage of recycled materials and aggregates production both increased by 5%. As such, the ratio was more or less stable.
There are three benefits to recycling asphalt mixes:
- lower power consumption and a reduction in greenhouse-gas emissions,
- reduction in wastage by recycling a non-renewable raw material, and reuse of bitumen and aggregates,
- savings for the customer (often from the public sector), who can obtain the same high-performance roadways as before but at a lower cost.
To measure its waste management performance, Colas has introduced a specific indicator to track the management and elimination of waste oil arising from the activities of all its subsidiaries and lines of business. Waste oil is regulated as hazardous waste in most countries and is the main hazardous material generated by Colas’ activities. The indicator calculates the ratio of waste oil (hydraulic and engine lubricating oil) that is recovered, by an official certified channel or reused responsibly, to the total amount of oil purchased. The optimum level is assumed to be around 80%, taking into account oil consumption and combustion by plant and vehicles. Colas obtained a ratio of 70% in 2013, which was slightly higher than in previous years, amid steady improvements in the reliability of the indicator. ISO 14001 certifications and annual self-assessments using checklists take account of all waste management.
Since July 2013, TF1 has changed the way in which it manages waste produced.
Each item of waste has its own waste-tracking document. Waste produced fell sharply to 611 tonnes in 2013 compared with 965 tonnes in 2012.

A new lease of life for old hardware - Bouygues
To keep abreast of the latest technological advances, IT equipment is replaced on a regular basis. But what happens to obsolete hardware? Bouygues has tasked ATF Gaia to give its old IT equipment a new lease of life. It collects old hardware from all the Group's sites in France. Credits: -…
