Recycling systems.Even after our extensive pre-show discussion in May of new recycling and size-reduction equipment, we turned up some additional new systems in Chicago for reclaiming EPS (Encapsulated PostScript) A PostScript file format used to transfer a graphic image between applications and platforms. EPS files contain PostScript code as well as an optional preview image in TIFF, WMF, PICT or EPSI, the latter being an ASCII-only format. , making plastic lumber, and washing bottles. And several suppliers not known primarily for recycling equipment announced plans to market film-scrap reclaim systems.
RECLAIM EPS FOAM
Erema North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. Inc., Topsfield, Mass., divulged details about a new way to reprocess re·proc·ess

To cause to undergo special or additional processing before reuse.
Verb 1. EPS foams. A dedicated system handles the melting, degassing degassing
adj related to degasification, the process by which dissolved gas is removed from water or other liquid solutions. , filtration, and pentane pen·tane

2. In keeping with: according to instructions.
3. Helmut Bacher, managing partner of Erema's Austrian parent company, the line also relies on "a sophisticated density control system," which monitors mixing/cutting torque in the densifier.
From the TVE, a gear pump A Gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps however are also widely used in chemical installations to pump fluid with a certain viscosity. feeds cleaned and degassed melt into a second 35:1 extruder, where pentane is metered in along with a nucleating agent and other additives. This liquid-cooled regassing extruder also serves as a heat exchanger to drop melt temperature rapidly and "freeze the gas" into the PS, says Bacher.
Also new from Erema is a downstream system for making plastic lumber or other profiles in direct extrusion. This segmented haul-off works much like a corrugator with a series of mold blocks continuously forming the profile in-line with the reclaim system.
IMPROVED WASH SYSTEM
In other turnkey systems news, John Brown Recycling Systems of South Attleboro, Mass., talked about the latest improvements to its wash system. Now the company's multi-stage wash section takes a "continuous counter-flow" approach, meaning that the reclaim and wash water move in opposite directions and that the reclaim moves in a slurry from one stage to another. This way, explains vice president James Glenn, the constantly flowing reclaim comes in contact with cleanest water as it progresses through the system. The continuous wash system comes in versions from 1000 to 3000 lb/hr.
IN-PLANT FILM RECLAIM
Three domestic machinery suppliers have established new relationships with offshore makers of in-plant film-reclaim systems:
* Alpine American, Natick, Mass., is representing Gamma Meccanica, an Italian maker of film-scrap repelletizing systems.
* Battenfeld Gloucester Engineering Co., Gloucester, Mass., announced it will market the Horai Hi-Pelleter from Japan. This compact unit densifies and then pelletizes film. Blown film product manager Bill Hellmuth notes the system is especially suited to film operations using grooved-feed extruders, which are intolerant to fluff.
* LCI LCI Livable Centers Initiative
LCI Life Cycle Inventory
LCI Landing Craft, Infantry
LCI La Chaine Info (French cable news channel)
LCI Lean Construction Institute
LCI Lions Club International of Charlotte, N.C., will market the Combi system built by Germany's Plastmachines GmbH. The unit consists of a densifier and short-barreled extruder/pelletizer.
