There is an essential system in urban life, which is often ignored by people, but all of us can't live without it, that is the garbage recycling system. The implementation of waste classification is not only related to everyone's living environment and the economic use of resources, but also an important embodiment of the level of social civilization. However, in many cities in the United States, EPS foam is an embarrassing presence in municipal waste.



The waste classification system in the United States has been very mature, and blue recycling bins can be seen everywhere on the streets. However, these trash bins clearly indicate that they will not accept foam#6 (a term of EPS foam), which is due to the difficulty of natural degradation and landfilling cost of EPS foam. The original intention of waste classification is to make the environment better, but EPS foam is difficult to degrade for hundreds of years. If it is continuously treated by landfill, it may go against the original intention.



According to the data of the EPSIA, the United States causes 155000 tons of waste EPS foam a year, but the average monthly recovery is only 5167 tons, and the recovery rate is very low. Many state governments began to issue EPS foam bans, hoping to curb the white pollution caused by EPS foam waste. However, with the arrival of covid-19, many of these prohibitions have been shelved or postponed. In this case, perhaps recycling is more effective than elimination?

GREENMAX, a famous recycling company in North America and located in California, also holds this view. Founded in 2010, the company has been in the field of recycling for ten years and is committed to contributing to foam recycling. In fact, it did. The EPS foam densifier designed by GREENMAX takes the hot-melt technology as the core and the crushing technology as the basic. It can efficiently process EPS foam and compact it into EPS foam ingots, which can be used for granulation.



Sphere Renewables is one of the largest manufacturers, suppliers, and solution providers of key components in the renewable energy industry in North America. It cooperates with GREENMAX to help promote its EPS foam recycling business. Sphere Renewables once paid more than $3000 a month for garbage disposal due to the management of EPS foam. However, the purchase of GREENMAX EPS foam densifier not only saves storage space through the compression of EPS foam volume but also saves a large amount of waste management fee.



Is EPS foam really a prohibited existence? Neither GREENMAX nor Sphere Renewables, which effectively uses EPS foam densifier, obviously think so. EPS foam is not so much waste as a resource. Without EPS foam densifier treatment, it is a waste that cannot be degraded for hundreds of years, while with the recycling system of EPS foam densifier, it will become a popular granulation raw material in the recycling market, which depends on the attitude towards EPS foam recycling. Therefore, It needs technologies such as EPS foam densifier. in addition, the traditional recycling concept should be changed. 

In the future, it is believed that the foam in municipal waste will be reasonably recycled and utilized due to the continuous emergence of companies with a sense of environmental responsibility such as GREENMAX, and the continuous development of recycling machines such as the EPS foam densifier.
