Division 1 The rate of recycled lead content is calculated as follows:

United Kingdom

$R_{Pb} = \frac{{Σ m}_{Pb output}}{m_{Pb input}} × 100$ , [mass %]

where:

R_Pb

calculated rate of recycled lead (Pb) from a recycling process for the purpose of Article 12(4) of Directive 2006/66/EC [in mass %];

m_{Pb output}

the mass of Pb in output fractions accounting for recycling is the share of Pb contained in these fractions which results from the recycling of lead-acid batteries and accumulators per calendar year [in tonnes];

m_{Pb input}

the mass of Pb in the input fraction entering the battery recycling process is defined as the yearly average Pb content of waste lead-acid batteries and accumulators multiplied by the input mass of lead-acid batteries and accumulators per calendar year [in tonnes].
