II. Description of the institutions involved in the data collection

Name of institution Description of key responsibilities

Add rows as appropriate.

III. Description of methods used

3.1. Single-use bottles placed on the market (Annex II, Table 1)

3.1.1. Description of the methodology for surveys and composition analysis

Where the weight of single-use bottles placed on the market is determined based on the weight of the waste generated from such products, a description of the methodology used for the sampling and the waste composition analysis referred to in Article 4.

Methodology used Variations taken into account Waste single-use bottles collected as mixed municipal waste Waste single-use bottles disposed of as litter

3.1.2. Description of any significant inconsistencies between the weight of single-use bottles placed on the market and the weight of packaging waste generated or any other related issues

Where appropriate, a description of corrective measures planned or taken.

Add rows as appropriate

3.2. Information on separately collected waste single-use bottles (Annex II, Table 2)

3.2.1. Description of the methods and sources for determining the weight of separately collected waste single-use bottles

Explain the practices that are taken into account for calculating the share of separately collected waste single-use bottles, and the methods for determining that waste single-use bottles collected together with other waste are of comparable quality to waste single-use bottles collected separately from any other waste. Include the documentation of the quality assurance systems and of the third party verification that are set up by the waste operators to verify that the conditions set out in Article 2(4)(b), points (i) and (ii), are fulfilled.

4.4 Differences in the data reported for the previous reference years

Significant methodological changes in the calculation method used for the current reference year in relation to the calculation method used for previous reference years, if any (in particular retrospective revisions, their nature and whether a break in the series has to be flagged for a certain year).

Add rows as appropriate

Where the reported data shows a greater than 10 % variation in relation to the data submitted for the previous reference year.

Reasons for the difference or the underlying cause for the differences in the weight of waste single-use bottles, single-use bottles placed on the market and/or waste single-use bottles separately collected.

Waste single-use bottles, single-use bottles placed on the market and/or waste single-use bottles separately collected Variation (%) Main reason for variation
