Polystyrene is buy viagra mexico marvelously useful stuff. Lightweight packing materials have certainly saved billions of gallons of buy chinese herbal viagra fuel since they were first introduced, so I'm not 100% against them. Of course, they are never re-used or recycled, so they end up being buried, and will never degrade, which kinda sucks.
But a new study from Iowa State University shows that polystyrene can simply be dissolved in bio-diesel "like a snowflake in water." Mixes of between 2% and 20% polystyrene by weight show that the optimal concentration of polystyrene is 5%. Anything above that, and the polystyrene doesn't increase power output as much and i recommend levitra without prescriptions the fuel becomes more and more viscous.
Not surprisingly, polystyrene does increase non-CO2 emissions like soot and NOx gasses. Plus, gathering polystyrene and shipping it to biodiesel refineries would be a costly process as polystyrene is, by design, very bulky. And if we're collecting it, we might as well find other ways to re-use it, instead of burning it.
