# Overview

Plasteax lays its foundation on three main pillars:

* Model 
* Database 
* API (application programming interface)

The **model** is the collection of methods and assumptions that allow for the calculation of granular information about the fates of plastic waste. The model is fed with high-quality data about global plastic production and trade, together with the most recent and available information about waste management practices in the countries of interest.&#x20;

By processing this data, the model is able to: (i) distribute the packaging waste generated among 6 packaging categories and 9 plastic polymers, and (ii) break down each of these elements in its possible end-of-life fates. For a more detailed description of the model underlying Plasteax, visit the [model page](/explainers/model.md).

Each time the Plasteax model 'runs', it produces data about at least one country, in at least one year; this data is then stored in the Plasteax **database**. The digital system that stores and structures the data produced.&#x20;

The **API** is the technology that allows users to interface directly with the database and allows you to query the entire, or just specific pieces, of the dataset. Visit the [API reference page](/api-reference.md) to learn more about the Plasteax API and how to use it. While for more details about the output produced by Plasteax we refer to the Plasteax output page. &#x20;
