EPS Compactor Contributes to the EPS Recycling Industry
The improvement of EPS recycling rate is said to be a result of the application of EPS compactors. In Canada, it is reported that the recycling rate of EPS packaging increased from 12% in 2009 to about 31% last year. Meanwhile, the recycling rate of food packaging increased to 32%.
According to the CPIA’s vice president, the main contributor to this improvement was the EPS compactor. By reducing the size of EPS waste, the shipping and collecting cost of EPS was greatly reduced and this opened up new opportunities for the EPS industry. In short, EPS recycling rate increased with the help of EPS compactors.
Equipments used for EPS recycling
It is reported that more than 93 million pounds of EPS was recycled during calendar year 2012 and the number is supposed to increase steadily. The EPS recycling procedure will not work at least not so effective without the help of EPS recycling equipments including EPS shredder, EPS compactor, EPS pelletizing machine etc.
Opportunities/Threats of EPS
-Durability / Sustainability
-Strong / light material
-Economic and competitive
-Plastics Image in General
-Lacking supporting evidence reports
-Added value by the productshape
-Low qty production series / higher variety
-Energy Efficiency regulation (Passive buildings)
-Competitors working on Weaknesses
-Renewable materials, like PLA
-consumer / retailer pressure
-Demand for high variety/ low quantity
-One component solution
What did they do?
Compress and reuse waste
• Pillows and some parts of the lounges are now made from fabrics and foam left over from other parts of the manufacturing process.
• A foam compactor have been installed to reduce the volume of waste needing to be stored and transported for recycling or disposal.
• Plastic, cardboard and timber packaging is reused or recycled.
• Foam is purchased cut to size, reducing the volume of offcuts.
• Timber frames have been redesigned so that the raw material is used more efficiently.
Why did they do it?
Waste was the starting point. The cost of waste disposal was significant enough to prompt the company to rethink manufacturing processes.
What are the outcomes?
Material costs have reduced because the new product designs use raw materials more efficiently.
Overall the volume of waste sent to landfill has reduced by 50%, and the cost of waste disposal has been cut by 70% due to changes in waste handling charges.
What were the costs and savings?
The foam compactor cost $6,000 to install. Combined with more efficient product design, the company is saving $180,000 per year. Overall, the payback period was less than six months.
Basically, the EPS from packaging is white in material and it has two types mainly clean post consumer
or dirty post consumer. This box is normally used in order to sustain the temperature level in its box. The
other accepted polystyrene materials are serving school trays, polystyrene cups, plates and bowls, packaging
used to protect electronic and computers, egg cartons, and small packaging of peanuts.
Study revealed by Naguchi et al., 1998, there are three methods used to recycling the EPS. Mechanical
recycling usually requires the combination of high temperatures & shear stresses (energy consumption).
Chemical recycling usually requires depolymerisation of the recycle material through solvolysis and thermal
catalytic (Melo et al., 2009). Read more
EPS foam is low-cost because it is mostly air. It can be printed upon, so therefore it is a good marketing piece. In the overall viewpoint it is a very good product. It can meet a lot of requirements for our customers.It is an excellent performer as a material. It has not had performance shortcomings that you would find in a paper cup or in alternative plastic materials. The foam cup is a good insulator for both hot and cold beverages.
The way it utilizes air and merges the beads together to form the insulated wall allows the hot beverages to remain hot without burning your hand or requiring a further insulated barrier between the two. For cold beverages it retains the cold. so your cup won’t sweat as a paper cup may do. Its make-up is very good from a performance standpoint.
There hasn’t been enough emphasis on the recycling of polystyrene foam due to market conditions and the low-cost of virgin resin to produce these products. However, as these issues have been raised.
The alternative materials, both plastic and paper, are certainly available. But when you look at the overall assessment of EPS foam it brings a total package, so to speak, to what the consumer needs. It is low-cost; it is functional. Again, you are using very little material compared to some of these alternatives. It’s mostly air. Its performance can’t be beat at this point. We’ve looked at a number of competitor paper products and they don’t offer the same insulation properties. They can’t be recycled to any great extent because of the polyethylene coating on the inside of the cup. As a result you are paying for something that is much more expensive to produce. It is more expensive to require restaurants and businesses to carry those lines of products. They are not as efficient as EPS foam and, ultimately, they cannot be recycled into other products.
