Question juridique clé
Whether the waste center satisfied the site-binding requirement of Art. 24 LAT outside the building zone
Solution extraite
The record was too incomplete to determine whether the project was objectively site-bound and whether suitable alternatives in the building zone existed.
Motifs extraits
The cantonal court had not sufficiently clarified the needs of the facility, possible variants within the building zone, and whether a partial solution or cooperation with other waste centers could make a forest site unnecessary.
