Thermodynamic Lifespan Modelling of Recycled PET under Circular Use Scenarios

A dataset compiled from 36 primary and contextual sources published between 2009 and 2026. It contains over 222 rows of thermal, molecular, mechanical, and thermodynamic properties for virgin and recycled PET, curated by Alexander Ugbodaga. The data supports research into polymer degradation and circular economy material flows.

Use Cases

• Model PET degradation kinetics based on recycling cycle count and processing temperature.
• Analyze circular economy material flows based on bottle-to-bottle pathway data.
• Compute entropy-based damage indices based on energy dissipated and entropy generation proxy.
• Characterize recycled polymer performance based on mechanical properties like tensile strength and cycles to failure.

Strengths

• Systematically compiled from 36 peer-reviewed sources (S01-S20, P001-P036).
• Includes over 222 rows of raw numeric data across eight structured sheets.
• Rows are classified by validation status (Accepted, Pending, Context only, Excluded) for flexible inclusion criteria.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown beyond the '222+ rows' mentioned, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the source studies from Europe, Asia, and North America.
