Recycling systems.

ACTION INDUSTRIES, INC.

Systems from Munchy Ltd. of the U.K. consist of reclaim extruder, filtering device, die-face pelletizer for air- or water-cooled pellets, and manual and automatic feeding systems. Handle all thermoplastic film, sheet, nonwovens, bottles, flake, and blocked-bag cut-outs from 50 to 2200 lb/hr. Washing and drying systems available in sizes to 2500 lb/hr.

New P65 Vented Mini Munchy repelletizing extrusion system reclaims film that has a high percentage of ink coverage, high moisture levels, or additives that can react during processing. The 132-lb/hr system comes in air-cooled and water-cooled versions, uses a 16:1 L/D screw, and draws 29 kw.

AEC/HYDRECLAIM

Specializes in in-line direct-recycle film-scrap reclaim systems, repelletizing systems, and gravimetric blending systems.

AMERICAN KUHNE INC.

Complete recycling systems from Kuhne Anlagenbau GmbH sort, wash, filter, and extrude 100% recycled film or sheet in a one-step process. (Also distributed by O/K International Corp.)

AUSTRONIC INSTRUMENTS INC.

Indumat recycling system for film, tape, monofilaments, bags, etc. A shredder, which preheats the material while cutting it into small pieces, is linked directly to the extruder. Preheating material saves half the horsepower in subsequent extrusion. Coarse filter ahead of the double slide-plate fine filter in the extruder removes large contaminants and thus prolongs life of fine filter. Hot die-face or strand pelletizing completes the process. Outputs to 2500 lb/hr.

BARTEX RECYCLING

Lines from Sikoplast GmbH are custom-built for most plastics. Use proprietary grinding and drying technology and a conical single-screw extruder connected to a polycondensation reactor, which upgrades PET's I.V. from 0.66 to 0.80. Also systems for recycling scrap into blown film, pipe, or profile.

LOUIS P. BATSON INC.

Revive systems from Sant' Andrea Novara of Italy process mixed resins contaminated with 5-20% paper, 5-8% aluminum, 510% wood, and 1-5% organic matter. Systems mix and extrude a narrow sheet 0.250.5 in. thick, which is hot-melt granulated for injection or extrusion. Includes shredder, granulator, 30:1 L/D extruder with 12 temperature zones, rolls, Ph-neutralizing water tank, hot-melt granulator, cyclone dryer, and deduster. Processes 220-990 lb/hr, depending on density.

JOHN BROWN RECYCLING SYSTEMS KVAERNER U.S. INC.

Complete recycling systems for post-consumer PE film and PET or HDPE bottles. Produce clean flake or pellets at 1000 to 3000 lb/hr. Include bale breakers, granulators, materials handling, and prewash, hot-wash and hydrocyclone separation systems. Also complete extrusion, polymer filtration, and pelletizing systems (strand or water-ring), plus system-wide control packages.

ECO-FOCUS, INC.

License Partek Corp.'s HDPE recycling line, which has a proprietary "single-pass" granulation system that produces uniform square flake with minimal fines. Two granulators each process up to 2500 lb/hr. A bale breaker and rotating trommel remove loose caps and dirt. After granulation comes an enclosed, high-shear, cylindrical washing tank. Next, a hydrocyclone removes "heavies" like PVC, PET, metal, and dirt. After spin drying, kinetic-energy scrubbers remove labels and glue. Dust and fines are removed by two aspirators. Flake is metered into an extruder with a vacuum pump that draws off moisture and volatiles. Melt is filtered with rotary screen changers and water-ring pelletized.

EREMA NORTH AMERICA INC.

Complete repelletizing systems for in-house, post-industrial or post-consumer plastics recycling. Patented "warm-feed" system predensifies, size reduces and prewarms scrap before it enters the extruder. This minimizes heat history, resulting in low-material degradation. Recycling systems include automatic back-flushing screen changers or continuous "laser" filter systems, depending on the type and amount of contamination in the scrap.

Systems available for PE, PP, PA, PET and most other materials at rates from 200 to 3000 lb/hr.

GALA INDUSTRIES, INC.

Recycle systems include equipment to wash, rinse and dry recycle materials removing dirt, loose paper, and chemical solutions. Rates from 10 to 5000 lb/hr. Centrifugal dryers process up to 100,000 lb/hr of material. Underwater pelletizers also available to pelletize reclaimed thermoplastic materials. (See ad p. 164.)

HAFNER INDUSTRIES, INC. (HII)

Proprietary chemical technologies treat and reclaim waste plastic mixtures. Most systems are closed-loop and handle two or more plastics such as HDPE, PVC, PET, PP, PUR, and PS, with or without water, oils, paper, metal, and glass. Systems produce plastics comparable to their virgin counterparts. Offers to license its technology or to form joint ventures.

MERRITT DAVIS CORP.

Polycycle Year 2000 line recycling system for film bales, rolls, slabs, and small purgings allows one-step size reduction without a granulator. New shredder design feeds a single-screw extruder and pelletizer using hooks to grab and cut material and a ram to feed shredded material to extruder. Extruder can be 3.5- to 10-in. diam. with 48:1 L/D and optional venting. Systems can be tailored for throughputs from 600 to 10,000 lb/hr.

MODERN MACHINERY OF BEAVERTON

Cryogenic cleaning system uses liquid nitrogen and water for flotation/separation. No soaps or caustic chemicals. Ground material is fed into the cryogenic chamber, where its temperature is reduced to -200 F. Brittle material is metered into a high-speed impacter where contaminants are drawn off by aspiration. Clean material is auger-fed to the float/sink process that separates PET from HDPE. Hot-air spin drying is followed by screening to remove PVC and fines. Capacities of 1000 and 2000 lb/hr.
