Four themes are addressed in the survey:
- The volume and nature of waste produced
- Waste treatment and cost
- Obstacles to waste management and prevention
- The level of information on existing waste management schemes
Two final questions concern:
- ISO 14001 certification
- The obligation to report releases

The establishments belong to the following sections of the Nomenclature of Economic Activities in the European Community (Nace rev. 2) :

H : transport and storage
I : accommodation and catering
J : Information and communication
K : financial and insurance activities
L : real estate activities
M : specialized, scientific and technical activities
N : administrative and support services activities
O : Public administration
P: teaching
Q : Human health and social action
R : Arts, entertainment and recreation
S : other service activities

Number of employees
1 : 1 to 9 employees
2 : 10 to 49 employees
3 : 50 to 199 employees
4 : 200 employees or more

The individual data represent one line per establishment responding to the survey. Most of the variables are qualitative and make it possible to count the establishments that carry out a particular waste prevention or management practice. Some variables are quantitative and are expressed in m³ (volume of waste produced) or in euros (amount spent on waste treatment).
The data published in an Insee Flash are percentages by sector of activity and size of institutions.

The interrogation unit is the establishment, identified by its SIRET number.

The statistical population is that of active and operating Hauts-de-France establishments (except for establishments in Section O of the administrations where non-operators are also included) with 1 or more employees in the tertiary sector (NACE Sections G to S -- Rev2).
