Plastic is a rich hydrocarbon product. The only concern is PVC. If the plastic waste material contains PVC, the best way to treat it is by steam decomposition. It is the most accepted process in the chemical industry. Green Fire uses a similar method to deal with plastic waste containing PVCs. During the PVC reaction, the PVC will produce a large amount of HCl, which unless removed, will shorten the life span of the system. To remove the chlorine, the GFS must, in processing of the material, add some additives to prevent the oil combining with the chlorine.
We recommend that the customer never process PVC as a single feedstock, it should be blended with other waste materials such as coal, rubber, organic matter or PP, PE, HDPE. In the processing of plastics, the major by-product is fuel-oil.
Only a small amount of carbon is produced (depending on plastic type). It may be less than 2%.
The yield rate of fuel-oil is about 30% ~ 70% depend on the plastic type.
The quantity of wastewater depends on the amount of chlorine but it can easily be neutralized prior to disposal.
