BRISBANE, AUSTRALIA — An Australian expanded polystyrene recycler can double exports to China and South Korea if its owner can convince more retailers to hand over EPS waste.
Polystyrene Recycling Queensland, a unit of Brisbane-based Global Interests Pty. Ltd., operates five granulators at electrical goods
retail outlets in Queensland and northern New South Wales, which shrink waste EPS volume by 66 percent. The granules are transported to PRQ’s compacting plant, nine miles south of Brisbane’s central business district, where they are compacted into recyclable EPS logs and shipped to Asia.
Leo Sines, PRQ owner and managing director, said PRQ ships a container of EPS logs weighing up to 17 tons each week to Chinese and Korean manufacturers. Those manufacturers process it into various products, including photo frame molds, coat hangers, synthetic timbers, and spoons and cutlery. Read more
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

WASHINGTON — New York City’s proposed ban on polystyrene foam packaging could cost nearly $100 million annually and hurt businesses across the state, according to a new study.
The study, conducted by research firm MB Public Affairs on behalf of the American Chemistry Council, shows that such a ban could nearly double food service packaging costs — while doing little to actually reduce waste.
“Total costs to replace plastic foam foodservice and drink containers and trays with the lowest-cost alternative are estimated at $91.3 million [per year.] This level translates into an effective minimum average cost increase of 94 percent,” the study says.
“In other words, for every $1.00 now spent on plastic foam foodservice and drink containers, NYC consumers and businesses will have to spend at least $1.94 on the alternative replacements, effectively doubling the cost to businesses.” 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
Over the past 20 years, the establishment of local recycling programs, in conjunction with recycling initiatives from large companies that regularly deal with EPS, such as Wal-Mart, have proven that creative and collaborative solutions produce positive results.
According to AFPR, EPS recycling consistently maintains one of the highest recycling rates among all of the plastics families. Including rigid, durable polystyrene, and other grade materials, EPS post-consumer and post-commercial recycling represents 50% of all post-use polystyrene recycled in the U.S. This is a significant achievement when considering that prior to 1988, the alliance says, EPS recycling was virtually nonexistent.
