Geographical representativeness description The ZEDA is located in southwest of Tianjin, which is the largest renewable resource processing industrial park in China.
Reference year 2016
Name
waste Polystyrene recycling; the recycled Polystyrene; mechanical recycling ; waste Polystyrene
Use advice for data set When using this data set, users should take into account the specific year of the data (2016) and the geographical location of the process (ZEDA in Tianjin, China). It is important to ensure the recycling process data relevance to the assessed product system and its geographical market. Methodological adjustments may be required for a different temporal or geographical context. Additionally, users must consider the inclusion of the end-of-life phase, particularly the potential environmental benefits linked to waste polystyrene mechanical recycling as opposed to disposal or incineration.
Technical purpose of product or process The recycled polystyrene described by this data set is intended for reintegration into the production cycle as a raw material substitute for virgin polystyrene. It is primarily used for manufacturing various plastic products where material quality allows, such as packaging materials, insulation, and household items.
