Introduction

Makersite has consistently integrated the GreenScreen method for Safer chemicals. The method is designed to identify chemicals of high concern and safer chemical alternatives through chemical hazard assessment. 

A more detailed insight into the method can be found on https://www.greenscreenchemicals.org/method.

Note: The GreenScreen results are automatically added to Product Groups and Substances once a CAS number is added and the is on the regulatory lists included in the GreenScreen.

Overview

Assess the substance risk for Acetone (liquid), and compare the Acetone GreenScreen score to the material Alternative Butanol. 

  1. Search for the Acetone (liquid) data set 

  2. Open the data set in the Analyse view

  3. Compare to other data sets (Butanol)

  4. MCDA results

Step 1

Please see the description of Search Bar Functionality for how to find data sets. 

Step 2

After searching, open the Dataset and scroll down till you reach the Greenscreen list translator score.

In the screenshot below is the explanation of the result table taken from Greenscreen handbook.

The risk type goes from very low (vL) to very high (vH)

Step 3

In the Information and Tool panel select 'Compare this to other datasets' to start a MCDA comparison.

Click on 'Add Dataset' in the top right corner of the pop-up and search for 'Hexane', ensure you select the Premium EcoInvent dataset, check the tick box in the top left corner of the Hexane dataset then select the blue 'Compare Product' button.

After adding Hexane, select the blue 'Analyze across dimensions' button, this will open to the MCDA page. You will find the criterion 'Hazard' compares the GreenScreen impact of the two materials.

 

Step 4

The criterion is calculated by simply adding values from 1-5 to the risk types and adding these up. The higher the number the more risk is assigned to the substance. 

The approach does not consider different weightings for different hazard groups. This is indicated through the extension 'Dimensionless'.
