UL 2809-2020 pdf free download.Environmental Claim Validation Procedure ( ECVP ) for Recycled Content. The efficiency factor is determined by subtracting the losses in the system due to leakage. processing efficiency, conversion efficiencies or any other factors which reduce the total pool of material available for allocation to consignments. Typically it is calculated by subtracting from bO% the sum of fractions lost to waste, converted to energy or any other losses which do not convert source material into final product leaving the system. All losses in the system must be included. When the conversion method used to convert from credits to mass product inherently includes overall system efficiency (for instance when using feedstock demand as a conversion factor) then the efficiency factor can be eliminated or set to 100% efficiency.
14.5.4 Allocation Each credit system shall use a tracking system for inputs and withdrawals from the system. Each entry in the tracking system must include at a minimum the following: the date of the entry. a record of the shipping documents for material going into the system, documentation of the source of material, documentation of the composition of the shipment (including the percent Defined Source content). the mass (or volume) of matenal in the shipment, conversion factors used to create credits for the shipment. and the number of credits added to the account. For withdrawals, the tracking system must record the date the credit is used. the identity of the material or substance carrying the recycled content, the conversion factors for converting credits to recycled mass units, the mass (or volume) of shipments of the material, the percent allocated recycled content being carried by the material, and shipping records. A percent allocated recycled content less than 100% is allowed. All shipping records shall be able to connect the credit or debit to an actual shipment of material. Total efficiency of material conversion within the system shall be measured and the available credits diminished by an amount equivalent to the efficiency losses of the system [efficiency factor) as specified in 14.5.3. Credits in the account shall have a lifetime of 365 days (366 if the period includes a leap year). In the absence of any another documented method, a first-in, first-out method for retiring credits will be used. Negative balances in the credit account are not allowed. If no credits are available, the outgoing material shipment cannot be allocated Defined Source content. Allocation of credits within the mass balance system boundary may be further directed or split based on process flow yields for different process co-products. Credits may be allocated to co-products based on the percentage yields of the co-product streams. Claims must state when yield splits are used for allocation of credits,
