Use EPS to Produce Better Vehicles
Inside a veihicle, you can find EPS used as bumpers, seat panels, dashboards, arm rests etc. Why should EPS be used in a vehicle? In short, the reason is that EPS has the properties of shock absorption, insulation, light weighted and rapid moulding.
If you have tonnes of used EPS each week and are compacting it before sending it to landfill — you could be recycling it instead. There are several recyclers who take compacted EPS; some like WES in Redcar and the Wales Environment Trust in Newport reprocess EPS into a clean pellet that can be used in applications like coat hangers, picture frames and replacement hardwood. Others, most notably Enviro in Grimsby who will take used fish boxes, export the compacted EPS to the Far East where it is recycled and used in new products like disposable cameras and video cases.
If you have tonnes of un-compacted, used EPS each week, some recyclers will install a compacter on your site and then take the compacted material for recycling. In all cases, the recycler will collect the compacted material if you have a large enough amount to make the journey economically viable and in some cases they will pay for the compacted EPS.
Harden can offer complete solution to EPS recycling.
1. Trays of expanded polystyrene are
compacted for shipment.
2. The compaction of expanded polystyrene allows for a reduction by 30-50 times the number of shipments needed to move the material.
3. The compacted blocks of expanded polystyrene are shredded into flakes in preparation for introduction into the pelletizing extruder.
4. The shredded flakes of expanded polystyrene are converted back into the polystyrene pellet.
5. The polystyrene pellets are mixed with additives and color in the compounding pelletizer line and re-pelletized prior to introduction into the profile lines for profile production.
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
The answer depends on several factors and should be considered relative to the level of technology utilized during production as well as that of the landfill in which it ends up. According to a production research study initiated by Franklin Associates (33 year-old life cycle analysis and solid waste management firm), polystyrene’s production can be less harmful to the environment than paper production.
For paper, it takes 33 grams (g) of wood, 4g’s of fuel (oil or gas), and 1.8g of non-recycled chemicals to make a single 10.1g cup. Polystyrene uses 1/6th of all the total production elements of paper cups and only 3% of the chemical ingredients. Read more
There are two insulation types: EPS and XPS, are popular in a variety of installations for the entire building envelope. The use of EPS and XPS insulation in building construction offers great flexibility, compatibility, and thermal efficiency for use at all areas of a building envelope. Picking between the two will depend on particular use; choosing the appropriate type is critical for proper insulation performance.
EPS and XPS are resistant to moisture; however, XPS is more common for below-grade waterproofing and roof systems where insulation is placed over the roof membrane (IRMA, or inverted roof membrane assembly). The IRMA concept is also utilized for insulating building walls, where polystyrene insulation is placed over a barrier membrane, with the siding or cladding system installed over the insulation layer.
