The variables with high partial non-response rate have to be analysed with caution because a significant proportion of the responses have therefore been imputed. Other elements are also to include, as precision of estimators and the fact to cross the variable or not with fields of diffusion.

Before any exploitation, it is also useful to assess the quality of the variables through their partial non-response rate and the confidence intervals provided in the survey quality indicators.

Below the ten variables with the hightest partial non-responses rates (between 34 % and 53 %) :
- Quantity of rubber waste;
- Quantity of mineral waste;
- Quantity of textile and leather waste;
- Quantity of equipment out of service;
- Quantity of chips, sawdust, bark and pallets;
- Quantity of canteen waste;
- Quantity of other non-hazardous waste;
- Quantity of used wooden crates;
- Share of packaging in other non-hazardous waste;
- Nature of other non-hazardous waste.
