English to Spanish Tech/Engineering Environment & Ecology Contrato de servicio para la limpieza de una ciudad

En este mismo contrato aparacen estos dos términos. Supongo que son algún tipo de recipiente para tirar basura, pero contenedor ya me aparace con anterioridad y no sé cómo traducirlos. Ahí va el contexto:

"Drop Box or Skip,"sometimes known as a “skip”, “roll-off” or “debris box,” means a wheeled or sledded Container or Compactor, generally with a capacity of six (6) to fifty (50) cubic meters, suitable for storage of Solid Waste, Recyclable Materials or Compostable Materials that is separately serviced by a truck, which Transports the Drop Box and the materials contained within to a Disposal Site, Processing Site, Transfer Station, or Composting Site.

Muchas gracias por adelantado.
