Whether you are doing the work yourself or being assigned to a professional, you need to know how to dispose of the waste without risk to people or the environment.

Waste treatment at a construction site

31 million tons of toxic waste...

Building sites are responsible for 31 million tons of waste, of which 5.3 million are attributable to the work of individuals.
The degree of toxicity or harmfulness of these residues is more or less important. It is therefore imperative to treat them differently.

  • If you do the work yourself, have the refuse reflex: sort before you go there.
  • If you use a building professional: he is responsible for the waste he produces. To eliminate them, he can not use the circuit put at your disposal for the garbage but the specific ones which are authorized to him
  • Waste management has become complex - environmental protection obliges - and at the same time more and more expensive. You will inevitably see the impact on the invoice of the company.

Know how to sort your hazardous waste or not

The goal is to reduce the impact on the environment and reduce their volume.
The goal to reach?

  1. Take advantage of the waste itself through reuse, recycling or incineration with energy recovery.
  2. Only land "ultimate" waste, ie waste that can no longer be valued or reduce its polluting nature.
There are four major groups:
  • Inert waste: natural stones, concrete, bricks, tiles... Once landfilled, they do not undergo transformation. They can not burn, decompose or produce chemical reactions. They are nevertheless reusable for embankments for example. They account for just under 70% of the mass of construction waste.
  • "Non-hazardous waste" such as plaster, metals, untreated wood, floor and wall coverings. They are intended for re-use or recycling circuits or incinerators with energy recovery.
  • Packaging (PVC covers, boxes...) are recyclable.
  • Hazardous waste such as paint residues, glue pots, treated wood... They must be eliminated on suitable treatment sites. Mixed with garbage, they are a threat especially for people in charge of collection. They represent 5% of the total waste.

What to bring to the rubbish

You can get rid of small volumes of construction waste that pose no risk to the people doing the processing or to the environment in your trash. If, in your municipality, selective sorting has been set up in particular by the provision of skips, it should be respected.
Larger volumes such as rubble and dangerous products will have to be deposited in waste disposal, just like metals, glass and paper. The approach is important: it allows the recycling of products that can be recycled and the elimination of others with environmentally friendly treatments.
Inquire previously at the town hall to know all the address, opening hours and conditions of access to the rubbish. It is often necessary to have a card issued on proof of the domicile.

A waste like no other: asbestos

Inhalation of asbestos fibers can cause various serious lung diseases.
Also when asbestos is present as building materials in a building (flocking, heat insulation, false ceilings, roofing...), do not proceed, yourself, to its removal but call a qualified professional in accordance with the regulations.
To remove asbestos waste associated with inert materials that have not lost their integrity (such as pipes, siding, undamaged roofing elements), it is imperative to store and transport them with care and to find the appropriate elimination map (see box: for information). Thus, it is necessary to avoid any action on the waste that could release fibers (break, saw, drill, brush, rub...) and wet them to prevent the flight of these possible fibers. It is then appropriate to pack as tight as possible. All these operations must be carried out by being protected by means of gloves, goggles and a mask, to be disposed of as waste containing asbestos.

What not to do with its waste

Whether one does one's own work or one has to deal with a professional, one and the other, one must not:


    • burn garbage on site, even when it comes to wood;
    • abandon waste anywhere including burying it;
    • discharge liquid hazardous products into the wastewater system.
