Expanded polystyrene does not contain toxic substances

One of the common properties of petroleum products is that they require more air to burn than trees and paper. Expanded polystyrene is no exception.

Accordingly, when expanded polystyrene is burnt in a simple incinerator a large amount of soot occurs because of the incomplete combustion that results from air deficiency.

However, if a sufficient amount of air is supplied in an exclusive incinerator, it generates almost the same amount of calories as kerosene and this makes it an effective clean fuel.

The ingredients of expanded polystyrene are only carbon and hydrogen, and substances which generate toxic gas, such as sulfur and chlorine, are not contained in it.

Chlorofluorocarbon gas is not used in the expanding agent.

Chlorofluorocarbon gas is not used in the expanding agent.

Ingredient beads contain an expanding agent in order to obtain a 50 times expansion.

The expanding agents used are hydrocarbon products, such as butane and pentane, and chlorofluorocarbon gas, which effects the ozone layer, has never been used in the beads method production of expanded polystyrene.

Gases generated at combustion Expanded polystyrene used for packaging household appliances and for food containers such as fish containers is made from only carbon and hydrogen, and therefore will turn into carbon gas (CO2), water (H20) and a bit of ash unless there is a sufficient amount of air used.
About toxic gases Corrosive gas (such as hydrogen chloride) which corrode incinerators and measuring instruments as well as toxic gases, such as chlorine gas are, not generated. No chlorofluorocarbon gas is used as an expanding agent because only butane, pentane and their compounds are used for the purpose.
Ash residue in incinerators Ash residue after complete combustion is less than 0.01% of the original weight, and it does not contain heavy metal such as lead and cadmium. Lead, cadmium, etc., are not contained in pigments and additives.
Heat release value Heat release value is 9,600 kcal/kg which is almost equivalent to heavy oil in terms of combustion energy. Kerosene 10,500 kcal/kg
Polyethylene 11,000 kcal/kg
Paper 3,800 kcal/kg
Wood 4,500 kcal/kg
