Techniques de la lutte à terre

Criblage par engin spécifique
Utiliser une cribleuse, couramment employée pour nettoyer les plages de sable, pour restaurer un estran pollué. Cette technique permet de récupérer du pétrole visqueux ou vieilli, ainsi que des déchets (algues... ).
La cribleuse est composée d'une lame d'attaque vibrante (prélèvement du sable), d'un tapis convoyeur tamiseur et d'un bac de réception des déchets. Le tapis est amovible et il en existe avec différents maillages. On peut ainsi choisir un tapis adapté à la taille des déchets qu'on veut récupérer.
Il est possible d'adapter un kit contenant des bandes transporteuses sur la cribleuse, afin de transférer directement les déchets sur une remorque.

If I were to name the things, I'd call them "beach skimmers" or "sand skimmers", at the risk of making them sound like a vehicle out of Star WarZ.

Similar contraptions - only floating - are used on the Seine to remove plastic bottles, twigs, bits of polystyrene, plastic bags, dead rats, and the like from the surface.
