ANNEX II METHODOLOGY FOR CALCULATING MUNICIPAL BIO-WASTE SEPARATED AND RECYCLED AT SOURCE REFERRED TO IN ARTICLE 4(3) 1. The amount of municipal bio-waste separated and recycled at source shall be calculated by using the following formula: m MBWRS = Σ n ARUi × (m Fi + m Gi ) where: m MBWRS means the mass of municipal bio-waste separated and recycled at source; n ARUi means the number of active recycling units for the recycling of municipal bio-waste at source in subsample i ; m Fi means the mass of food and kitchen municipal bio-waste recycled at source per active recycling unit in subsample i ; and m Gi means the mass of garden and park municipal bio-waste recycled at source per active recycling unit in subsample i . 2. The number of active recycling units for the recycling of municipal bio-waste at source shall include only those recycling units that are used by waste producers. That number shall be retrieved from registers of such units or shall be obtained through surveys of households. 3. The amount of municipal bio-waste that is recycled at source per active recycling unit shall be determined through direct or indirect measurement of bio-waste entering active recycling units as specified in points 4 and 5. 4. Direct measurement requires measuring the input to the active recycling unit or its output under the following conditions: (a) the measurement shall be carried out, where feasible, by or on behalf of public authorities; (b) where the measurement is carried out by the waste producers themselves, Member States shall ensure that the reported amounts are subject to plausibility checks and are adjusted to the effect that the amount of bio-waste separated and recycled at source per person in no case exceeds the average amount per capita of municipal bio-waste collected by waste operators at national, regional or local level; (c) where the output of an active recycling unit is measured, a reliable coefficient shall be applied in order to calculate the amount of the input. 5. Indirect measurement requires measuring the following amounts through composition surveys of collected municipal waste, which take account of municipal bio-waste waste that is separately collected and of municipal bio-waste that is not separately collected: (a) the amount of bio-waste contained in collected municipal waste that is generated by households or in areas where waste is separated and recycled at source; (b) the amount of bio-waste contained in collected municipal waste that is generated by households or in areas with characteristics that are similar to the characteristics of households or areas referred to in point (a), where waste is not separated and recycled at source. The amount of municipal bio-waste that is separated and recycled at source shall be determined based on the difference between the amounts specified in points (a) and (b). 6. The methodology to determine the amount of municipal bio-waste that is separated and recycled at source per active recycling unit pursuant to points 3 to 5, in particular the sampling methods used in surveys to collect data, shall reflect at least the following factors: (a) the size and type of households that use an active recycling unit in the case of food and kitchen waste; (b) the size and management of gardens and parks served by an active recycling unit in the case of garden and park waste; (c) the available collection system, in particular the complementary use of waste collection services for bio-waste and mixed municipal waste; (d) the level and seasonality of municipal bio-waste generation. 7. Where the share of municipal bio-waste separated and recycled at source in all municipal waste generated is less than 5 % at national level, Member States may use a simplified methodology to calculate municipal bio-waste separated and recycled at source by applying the following formula: m MBWRS = n P × m BWpp × q RS where: m MBWRS means the mass of municipal bio-waste separated and recycled at source; n P means the number of persons involved in municipal bio-waste recycling at source; m BWpp means the mass of generated municipal bio-waste per capita; and q RS means a coefficient representing the share of municipal bio-waste generated that is likely to be separated and recycled at source in the total amount of municipal bio-waste generated. 8. For the purposes of applying the formula laid down in point 7 Member States shall ensure that: (a) m BWpp is calculated on the basis of surveys on the composition of separately collected and mixed municipal waste at national, regional or local level as appropriate; (b) q RS is determined by taking into account the factors listed in points (a) to (d) of point 6. 9. The formulas laid down in this Annex may be applied to all municipal bio-waste separated and recycled at source or only to food and kitchen municipal bio-waste separated and recycled at source. 10. The surveys to collect data for the purposes of applying the formulas laid down in this Annex shall be carried out for the first year of reporting on municipal bio-waste separated and recycled at source and thereafter at least every five years, and for other years whenever there are reasons to expect significant changes in the amount of municipal bio-waste separated and recycled at source. Member States may update the reported amount of municipal waste recycled at source for the years for which data is not collected by using appropriate estimates. 11. The surveys to collect data for the purposes of applying the formulas laid down in this Annex shall be based on representative samples and appropriate sub-samples. The results of those surveys shall be statistically significant according to scientifically accepted statistical techniques. 12. Member States shall take appropriate measures to ensure that the reported amounts of municipal bio-waste that is separated and recycled at source are not overestimated.
