+# Dataset Creation
+
+The [BIGPATENT](https://huggingface.co/datasets/big_patent) dataset is the source for this dataset.
+
+In a first step, abstracts of BIGPATENT were filtered by the terms "plastics" and "polymer". The resulting "Plastics" dataset contained 64.372 samples.
+
+In a second step, the 64.372 samples were filtered by terms which define "green plastics". 
+
+"Green Plastics" are defined by the list of terms: 
+"degrada", "recycl", "bio", "compost", "bact", "waste recovery", "zero waste", "sustainab", "Bio-Based", "Bio-Degradable", "Renewable", "Green Plastics", "Renewable",  "Degradable", "Compostable", "Bio-resorbable", "Bio-soluble", "Cellulose", "Biodegradable","Mycelium", "Recyclability", "Degradability", "Bio-Polymer", "reuse", "reusable",  "reusing", "Degradation", "Multiple Use", "Bioplastic", "Polyhydroxyalkanoates", "PHA", "Polylactide", "PLA", "Polyglycolide", "PGA"
+(some terms might repeat)
+
+The group of "Green Plastics" containing 5.598 rows was labeled as 1. 
+
+An equal amount of samples (=5.598 rows) were randomly chosen from the "Plastics" dataset was defined as "Not Green Plastics" and labeled as 0. 
+
+Both groups ("Green Plastics" and "Not Green Plastics") were merged together.
