Homogeneous Household waste

Sulfur chemistry is important both in combustion and in the petrochemical industry. Most fossil fuels contain sulfur, and also biofuels and household waste have a sulfur content. As a consequence sulfur species are often present in combustion processes. Knowledge of gas-phase sulfur chemistry occurring in combustion has bearing on pollutant emissions and on system corrosion. Air pollution by SO2 still constitutes a major environmental concern and search for control techniques has motivated research also on high-temperature homogeneous sulfur chemistry. However, more recent work on sulfur chemistry has been concerned mainly with the effect of sulfur on other pollutant emissions, such as NO and CO, and with the SO3/SO2 ratio, which is important for the corrosive potential of the flue gas and for formation of sulfur containing aerosols. 

In this scenario, compostable bioplastics can play a key role. Typical examples are waste bags for the collection of household waste, disposable catering items nsed in fast-food restaurants and agricultural mulch films. Bioplastics do not need separation but can be collected and treated in a homogeneous way with the other organic waste, making the system more efficient.
