Tolivac, Norba haven't made the rotary-screw machine for a couple of decades; they've fallen in with the trend toward intermittent compaction via the slide/sweep panel system you saw on the site. However, hybrid powertrain is a nice idea, "who says it's only for cars?" Probably saves fuel also.
Kuka originated in the 30s in Germany, first as a rotating drum with deep spiral blades, similar to a horizontal concrete mixer but with a loading aperture in a tailgate, the whole body enclosed in sheet paneling for soundproofing. In the UK, Lewin made a similar machine with sufficient differences to overcome patent issues. The Kuka Shark design was early 1960s, with a very significant difference: attached to the tailgate was a cone-shaped fixture with a spiral guide-plate around its outer circumference, the cone projecting inward into the body, and having a cutout opening at its bottom via which material was loaded. The body didn't have deep spirals any more; but instead a set of ribs at the rear of the cylindrical drum to engage the material and lift it into the drum, and a shallow spiral whose primary purpose was to assist getting the last of the load out during the discharge cycle at the landfill or transfer station.
Yes, this could and did grind up white goods admirably, along with anything else one cared to put into it. The operating principle was that as the load built up in the drum, the stationary spiral guide plate acted in the same manner as a revolving screw (the drum revolved around the screw; neat, eh?) to achieve an extraordinary degree of compression.
Best of all this one is still made today: Kuka was absorbed into the Faun organization, and you can find it on their website as the Faun Rotopress. That's a total historical lineage of nearly 70 years on the rotating-drum compactor design, and 40 years on the "Shark" principle. Simplest compactor design on the market anywhere.
By the way, the reciprocating ram with fall-back shield was also 1930s, in this case France, invented by Fernand Rey. Still used in static compactors and in continuous side-loading vehicles such as LoDal in the USA, so it now has 70+ years of history as well. In the UK this design was adopted by Shelvoke & Drewry for their Pakamatic in the 1960s, but alas, S&D are no longer in existence (I think Semat, the descendant of the Rey organization, is still around). S&D was truly the Rolls Royce of municipal vehicles, with world-class engineering & craftsmanship second to none, every machine manufactured the old way, by hand, one at a time, built-to-order.
