With regard to the quantities of sludge, the data for 2020, as it has already been the case for 2018, are expressed as "dry matter". Since Luxembourg does not have a national conversion factor, the conversion factors as presented in the Eurostat working document WASTE WG 79/3.1 b (2008) were applied. A conversion factor of 0.2 was applied to the new EWC-Stat 4 category "Sludges and liquid wastes from waste treatment" (03.31), based on the approach in the abovementioned document. |

a) Annual reports Annual reports require many hours of data entry and checking before they can be reliably used as data sources. Furthermore, it is often the case that reports are only submitted to the Administration after several reminders. However, the greatest difficulty to overcome is double counting. To this end, data must be validated case by case. A methodology has been developed to eliminate as far as possible double counting when several shippers in succession are involved in the collection and shipment of the same waste (for example: company A collects and transports waste shipment F to a sorting or packaging facility, then shipper B transports waste shipment F from the facility to the final consignee; waste shipment F is included in the annual reports of both shipper A and shipper B. Based on the information presented above, double counting can be avoided as far as possible by following a well-defined methodology, the key features of which are as follows: - validation only of the quantities of waste transported where these figures are identical to the quantities of waste traded; - validation of the quantities of waste exported directly; - validation of the quantities of waste permanently disposed of or recycled in a national facility. In the context of the reports from waste shippers and traders, declarants must indicate whether the producer is the original producer of the waste or whether the waste comes from another collector or a waste recovery and disposal facility. This information also enables double counting to be eliminated. The Environment Administration converts data in the annual reports which are expressed in cubic metres, litres or units into unit weight according to its own correlation table. Thus, for example, the following conversion factor is applied in calculations involving inert waste: 1 m3 = 1.8 t. The NACE code is assigned to the producer by either the waste shippers/traders or the waste treatment facilities. Luxembourg attributes the waste to the producer (the party which produced the waste as a result of its activity) and not to the party which delivered the waste to a treatment facility. This explains the poor comparability of certain categories of waste in the different Member States (such as end-of-life vehicles, contaminated soils and dredging spoils). The allocation of end-of-life vehicles is fairly complicated. The vast majority of end-of-life vehicles come from private individuals. However, the collectors assign NACE code 45.112 Commerce to vehicles taken over by garages. Written off end-of-life vehicles are assigned NACE 38 by the shippers taking them to the shredders. The same problem was found in assigning a NACE code to polluted soils: Who is the producer? The oil company treating its service station, the drilling company or the consultancy organising and overseeing the work? In addition, in Luxembourg's case, the issue of the allocation of waste for which the communes are responsible has not been definitively resolved. Some employ private companies, others carry out their own collections. If the waste is collected by a private company, should it be attributed to private individuals or to communes? The same problem arises for waste generated by communal services: waste from cleaning roads, cemetery waste, waste from communal workshops, etc. In this context, for the purposes of simplification and consistency, inert waste is systematically assigned NACE Rev. 2 code 43.110 Demolition work. b) Double counting/primary waste-secondary waste Double counting is avoided as far as possible in order to obtain an accurate picture of the waste generated in Luxembourg. This applies to both primary waste and secondary waste. Waste is validated as new waste when its nature changes: Thus an untreated vehicle (160104) is counted when it enters a treatment plant, and is counted as secondary waste (160106) when it leaves the treatment plant to be sent to a shredder. This is not the case for cardboard entering a sorting facility and subsequently leaving the facility to be sent to a paper mill, as there is no change in the nature/composition of the waste. In the tables relating to waste generation (GENER) and treatment (TREATM), there may be very slight discrepancies between the totals (by waste, activity, treatment, hazardous and non-hazardous) calculated automatically by the Web Form and those obtained from the Environment Administration's internal calculation tables. This is due to the fact that the information is collected in kilograms and litres in Luxembourg. When they are converted to unit tonnes, the quantities are either rounded down or rounded up and then added together. c) Capacity of waste recovery and disposal facilities The capacity of waste recovery and disposal facilities is determined on the basis of several criteria: 1) The operational capacity authorised by the ministerial decree; 2) The amount of waste treated in 2014 as indicated in the annual report; 3) The capacity in Megagrams per hour: crushing and screening plants for inert waste notify their capacity in Megagrams per hour. This capacity is multiplied by eight working hours per day, 200 working days per year. The figure may vary according to the nature of the material to be treated; 4) Land treatment resulting in benefit to agriculture or ecological improvement (R10) covers only sewage sludge; 5) For backfilling, all concerned facilities have been analysed based on the Eurostat backfilling criteria, an the ones fulfilling the latter, have been inclueded under the treatment category 3b in the REGIO 1 webform. |

7.1. Timeliness | |||
Data are collected annually using standardised forms. The deadline for submission of annual reports is 31 March of the year following the reporting year. Companies are required to produce annual reports. Once the Administration has received the reports, their consistency is checked before inputting the data: this involves checking the consistency of the waste transported in relation to the type of waste, and the consistency of waste treatment methods according to the type of waste. If problems are detected, the values are compared to those of previous years or to data in the database of records of notifications on shipments of waste. If there is a discrepancy between the values, the establishment concerned is contacted to confirm the validity of the data. This is also the case if the annual report is incomplete. Depending on staff availability, reports are entered into a centralised database. In general, data entry takes two to three months. Data control and validation is carried out by someone other than the person who entered the data into the database. This allows errors made during manual data entry to be spotted. It takes around six weeks to verify and validate the data. |
