GMS XPS / EPS Recycling Plants

GMS Plastic Machinery Pvt. Ltd., has developed many models of Compact Fully Automatic Recycling Machine especially for EPS / XPS waste wherein one must feed the scrap material and collect the finished granules from the other end of the machine.

GMS is aware how to feed EPS/XPS waste to our extrusion equipment without degrading the waste. GMS offers special design Screw and barrels which permit homogeneous mixing, consistency of colours, etc. The GMS Online Olio Dynamic Screen Changer permits reduction of downtime of plant and can be changed with a flick of a button within seconds. This permits increase in output and reduction in wastage, downtime, power consumption and increase in output.

The Water Ring Hot Die Face Cutter Unit reduces wastage due to thread breakage which is more than 5% in strand pelletising equipment. It permits Compact Dry granules, Consistent size, Virgin alike round pellets shape. The finished granules can be easily compared to virgin alike material because it has the same feel and look like any natural granules.

Recycling as everyone knows is a great boon to the environment. Advanced Technology as compared to traditional recycling has many advantages:

• Requires lesser labour and operators,
• Fully Automatic Plants with clean room features,
• Granules can be directly bagged,
• No manual contact during processing,
• Reduced scrap generation during processing,
• Even round pellets,
• Lot of Waste during strand breakage,
• Lot of waste during Filter Change in terms and time, energy and production,
• Lot of gases remain trapped in the granules due to un-vented Extruders,
• Colour Variation due to degradation during Filter change.
• Reduced MFI as compared to advanced GMS Technologies,

The lines are energy efficient because power consumption is very less as compared to any traditional Recycling Lines. There is also indirect Energy efficiency using GMS technology as reprocessed material provide higher output as against Granules produced from traditional machines. We have conducted a case study on cost effectiveness to a processor:

• A moulder using Injection Moulding Machine producing Buckets, can achieve 3 Cycles a minute or 180 cycles per hour.
• The same machine when using recycled granules made from our technological advanced equipment in Ratio of 20:80 (20 being recycled, 80 being Virgin) can achieve 220 cycles per hour.
• But when using recycled granules made from traditional recycling equipment with cylindrical shaped and uneven granules mixed with virgin material in the same Ratio of 20:80 can achieve only 150 Cycles per hour.
• This means a clear savings of 10 to 12% in energy consumption only. Over and above there is additional savings in terms of time and labour.

Another advantage of GMS advanced technology over traditional technology is when you recycle Light Weight waste. With Traditional Technology you first need to produce lumps, grind them, and then recycle them again to achieve final granules or use a mother baby (Double Stage recycling) machine which depletes the quality. GMS recycling Machines are Single stage machines which give higher output using a single extruder with lower power requirements and higher quality Granules.

EPS / XPS recycling were a huge problem especially with the very low (0.2 to 0.6) density waste. Thermoformed Article producers and Insulation Sheet producers were selling of their waste edge trims at very low prices and loosing on expensive polymer. On the other hand, with the surge in polymer prices, processors decided to adopt in house recycling because it would not only benefit them in saving cost of raw material but prevent them from selling of the scraps at extremely low rates.
