2.4 Step four: Determine the weight of designated materials for each product/service/activity

The first step is to determine all the material categories for which you are reporting and which material list to use when filing your annual steward reports using the WeRecycle Portal. The national material list (Part Three of this guidebook) and province-specific material lists have been developed to provide stewards with the option of filing nationally or provincially. The Portal User Guide provides instructions on how to select your reporting preferences using the national or provincial material lists.

Next you will need to weigh the packaging and identify packaging material type. Some stewards use a specially designed system or database, or use Excel spreadsheets.

There are several options for obtaining weights and material sub-categories where they are not already known. These include:

Option  1 – Obtain packaging data (the materials and their weights) from vendors or industry associations where available. If this method is selected, steps should be taken to ensure the accuracy of weights provided by the vendors. This could include a discussion with the vendor as to how the weights were obtained or testing the data for accuracy. Ensure that processes are in place to obtain accurate weights (i.e. not estimated weights) and material classifications.

Option 2 – Physically examine the packaging components to determine their weights and material categories. This may require the acquisition of a scale which is accurate at least 0.1 grams in order to obtain the weights of packaging materials.

For either option, care should be taken to exclude any materials that are not provided to the residential consumer as noted in sections 2.3.1 and 2.3.2. Please ensure you keep all supporting documentation  on the weights you have deducted or excluded from your reports..

Where products supplied include designated materials such as magazines or paper for general use (e.g. blank paper for printing), the weight of these designated materials should be included in the weights to be reported.

Please refer to section 2.5.2 if you are using the Average Bill of Materials (ABOM) method for reporting.
