(51)In order to take into account the risks related to a possible insufficient supply of a specific plastic waste for recycling that might lead to excessive prices or adverse effects on health, safety and the environment, the power to adopt acts in accordance with Article 290 TFEU should be delegated to the Commission in respect of adjusting the minimum percentages of recycled content recovered from post-consumer plastic waste. In evaluating the justification of such a delegated act, the Commission should assess well-reasoned requests from natural and legal persons.
