EPS is a highly visible material because it is bulky and predominantly white, and this highly visible feature makes it easy to produce a large amount of used EPS that is discarded. In fact, EPS is only urban solid waste 0.1% of the material (garbage).
And there are several EPS disposal ways which can be used to deal with the polystyrene.
EPS is 100% recyclable, and the annual recovery of tens of thousands of tons. The recovered EPS can be mechanically reduced to 50-60% or reduced by 90% by heat, and the compressed or hot-blown material can be made into recycled polystyrene particles and used to make hanger, Replace hardwood with CD racks.
Another way to extract value from the use of plastic is to recover energy from clean burning and to prevent waste from flowing into the landfill. The effective method of maximizing the use and benefit of plastic resources is to burn waste to produce electrical or thermal energy. This method has been widely used in Asia, Europe and other regions.
EPS has a very high heat value, one kilogram of foamed polystyrene contains energy, equivalent to 1.3 liters of heated fuel. In a household trash can store more than a year of waste, that contains enough to heat 500 bath water or let the TV boot 5000 hours of energy.
Such EPS waste management methods do not emit toxic substances. This is a modern plant for high temperature incineration, byproducts for steam, carbon dioxide and very low non-toxic ashes, which are less polluted than traditional campfire. So far, we believe that landfill is the final option in all waste management practices. If EPS is buried, it means that we have not made good use of natural resources through recycling or energy recovery.
However, if there are no other viable options, EPS can also be safely put into the landfill. Because it is inert, non-toxic, stable, and will not break down, so EPS will not form methane in the atmosphere or any other chemical substances, it will not pollute the groundwater.
