Assessment of waste oil collection categories regarding suitability for material recycling and impacts of mobility and technical changes on the distribution and composition of waste oil collection categories (FKZ 3721 34 340)

The EU Waste Framework Directive establishes measures to protect the environment and human health by preventing or reducing the harmful effects of the generation and management of waste, reducing the overall impact of resource use and improving the efficiency of resource use (Art. 1.).

Article 21 specifically refers to waste oils and includes a) Separate collection, as far as technically feasible, b) Treatment according to Article 4 (waste hierarchy, i.e. according to the order of priority) and 13 (protection of human health), c) Keeping waste oils with different properties separate (mixing ban), as far as technically feasible and economically viable.

The regeneration to be given priority under Article 21 is defined as "any recycling process whereby base oils can be obtained by refining waste oils, in particular by separating the pollutants, oxidation products and additives contained in such oils." Article 21(4) states that "by December 31, 2022, the Commission shall examine the data on waste oils provided by Member States in accordance with Article 37(4) to determine whether measures can be taken to address waste oils, including the setting of quantitative targets for the regeneration of waste oils and any other measures to promote the regeneration of waste oils. To this end, the Commission shall submit a report to the European Parliament and the Council, accompanied, if appropriate, by a legislative proposal."

The project serves to prepare and accompany these measures at the national level and to review the calculation model used at UBA for material flow analysis. Against the background of progressive technical changes and before changes in the composition of waste oil, the following work in particular is to be carried out in the tendered project: a) Review of the existing collection categories / determination of which waste oils are suitable for regeneration, in particular examination of whether waste oils in collection categories 2 and 3 are suitable for recycling. For this purpose, waste oils are to be examined with regard to their composition, in particular with regard to contaminants (from additives as well as from use) and it is to be checked whether the allocation to the collection categories of Annex 1 of the Waste Oil Ordinance corresponds to the current technical possibilities for recycling. B) Review of the calculation model (back calculation model) for determining the waste oil quantity flows and updating of the calculations. C) Analysis and forecast of the effects of the current and in the near future expected mobility and technology changes (other oils, changed additive composition, increasing share of e-mobility, …) on the distribution and qualities of the collection categories. D) Development of recommendations for a revision of the Waste Oil Ordinance (e.g. cutting of the collection categories, definition of categories suitable for regeneration, target quotas) and estimation of the necessary compliance effort.
