This dataset presents information on the most sold products in sampled grocery shops in Santa Cruz island, Galápagos. Data were collected in July and August 2023, from 13 grocery shops, including small, medium and large shops, as well as open markets. The dataset includes product name, manufacture location, manufacture date, product weight, type and weight of packaging and polymer type. The data were collected to explore alternatives for reducing inland plastic waste through a circular economy approach. This work is part of a NERC funded project (NE/V005448/1), that aims to reduce plastic in the Galápagos Islands and the Eastern Pacific.
