2.1. Data description | ||||||||||||
The waste generated and treated in Romania is delivered in three data sets: Data set 1: Waste generation by waste category (EWC-STAT) and economic activities (NACE), tonnes/year; Data set 2: Waste treatment by waste category (EWC-STAT) and treatment category, tonnes/year; Data set 3: Number and capacity of recovery and disposal facilities (per NUTS 2 region), tonnes/year and cubic metres.

Data is collected from waste generators, collectors and companies that treat waste, as described at 3.1 |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3.4. Data validation | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Companies that report data on waste generation and treatment fill in specific questionnaires within the Integrated Environmental Information System that is managed by NEPA. Validation procedures include: i) primary logical and mathematical validation rules in each questionnaire; ii) specific plausibility checks for each type of questionnaire (waste codes, quantities, R / D codes etc.); iii) comparison between years for the same respondent; iv) cross-checking between different types of questionnaires; v) specific validation rules recommended by EUROSTAT. Differences between 2020 and 2018 in terms of waste generation and treatment (both for hazardous and non-hazardous waste) are due to changes in economic activities – some activities ceased in 2020 (this is the case also for mining activities), whilst other new activities started in 2020. There have been also cases of waste reclassification from hazardous to non-hazardous. Differences between generated and treated quantities come mainly from changing the waste code during the treatment flow, changing the hazardous status into non-hazardous, ceasing the waste status after a treatment step. |

Questionnaires are filled in on-line by companies. EPAs correct and validate at local level (it is an arithmetic control and a logical control of the data, e.g. plausibility check based on amount of waste quantity / employees / NACE code / comparability with the last year). Then NEPA aggregates, process and validates data at national level, according to the Manual / Guidelines on waste statistics. The IT software from EIS has also certain primary validation rules, both arithmetic and logic. |
