Automatic summary, not yet reviewed
- A new eighth additional provision in the Waste Act exempts from administrative authorization the use of transformed animal flour as fuel in cement kilns, ceramic plants or thermal power stations. Facility owners must notify the environmental body of their Autonomous Community for registration.
- Quantity limits are set: in cement or ceramic plants, the flour cannot exceed 10 % of each plant's production capacity. In thermal power stations, it cannot exceed 10 % of the energy generated when waste is used as fuel, or 5 % when fossil fuels are used.
- If the facility already holds the required operating license, starting to burn this flour is not a substantial modification. The owner only needs to notify the competent authority.
- Autonomous Communities may adopt additional environmental protection rules, including requiring authorization. They may also exempt other similar activities, such as burning this flour in other incineration facilities or recovering the fats extracted during processing, notifying the Ministry of the Environment.
Who it affects
- Cement and ceramic product factories: They can use this flour as fuel without prior authorization, subject to limits and prior notification.
