Facts about EPS in Landfills
Will EPS Degrade in Landfills?
EPS products do not degrade in landfills. However it may surprise you that the commonly known “degradable” matrials like paper even food waste do not degrade in most landfills neither. How come? Actually, there are three types of landfill fields nowadays including anaerobic bioreactor landfill, aerobic landfill and semi-aerobic landfill. The most popular landfill across the world is the first kind which is easier to build and maintain. But the low expense comes at the cost of some trade-offs. One of the problem it brings is that air is deprived in these landfills which makes degradation harder for not only nondegradable materials like EPS but also degradable materials like paper.
Current situation of EPS in Landfills
It is reported that the largest component in landfills is paper (50%) while plastic constitute about 10% of the waste. In Europe, EPS products are completely banned from landfills. It is the original manufacturer who is responsible for the management of EPS waste. The land available for landfill is very limited compared to the rapid increasing amount of waste. I One of the reason for countries banned it from landfills should be that EPS is made light weighted which means its weight-volume ratio is very small. By using EPS compactors its weight can be up to 90 times bigger with the same volume. This should be benificial for the landfilling or recycling of EPS.
