Polystyrene recycling program is considered to change in policy of San Diego

Last July, San Diego became one of the cities to accept polystyrene containers as part of its curbside recycling program, which stood out among many cities that banned polystyrene products.

San Diego has decided to take a more commercial approach by allowing restaurants and other businesses to place containers deemed cost-effective in blue bins.



Considering more than 100 towns in California has banned polystyrene products, San Diego’s polystyrene recycling program last year surprised us all. State-wide bans have been under discussion for years, though so far this effort has not been successful.

Unfortunately, it is reported that San Diego Council has introduced a proposal to ban polystyrene containers recently.

This measure is not groundless, although polystyrene material is technically recyclable, But the recycling process turns out to be not cost-effective. San Diego's polystyrene recycling program costs the city about $90000 a year. The question remains as how to deal with food pollution and whether it is a good way to bring profits.



Some ban opponents are still making efforts to polystyrene recycling. They are trying to find more economically effective ways. By adopting professional foam recycling machines as GREENMAX foam densifier, many of the American counties has achieved foam volume reduction to reduce storage and transportation costs during the recycling process.

GREENMAX foam densiifer is a melting machine which can realize foam volume reduction at a ratio of 90:1. The crushing and melting processes turn loose foam waste into tight ingots that 90 times smaller than before. GREENMAX aims to make the recycling process simpler and more efficient.



The ability of GREENMAX technology to prevent waste polystyrene from landfills and create a sustainable foam material with global efforts of waste diversion and the move to a circular economy.
