LCA — environmental impact study summary

Summary information taken from:

A Benchmark Study of the Zero Waste Cups, The LCA Centre, 2020.

Addendum to the Benchmark Study of the Zero Waste Cups (ReCiPe), The LCA Centre 2019.

About this summary

The data in this summary are taken from two studies carried out by The LCA Centre

Overview

All of the information in this summary is taken from two extensive environmental impact studies carried out by The LCA Centre for Bockatech:

• A Benchmark Study of the Zero Waste Cups (ISO: 14040 &14044), 2020 Covering: Global Warming Potential (GWP), Cumulative Energy Demand (CED) and Water Resource

• Addendum to the Benchmark Study of the Zero Waste Cups (ReCiPe), 2019 Covering: 18 environmental mechanisms

Dual wall paper cup PE lined Incinerated CN Single use

Single wall paper cup PE lined Incinerated CN Single use

Additional cups covered by the studies included: PP, PET ,rPET, PLA, PLA composted, PE/Paper/PE

Normalisation

Cups analysed in the studies had different capacities. These have been ‘normalised’ by applying a scaling factor. All results are for 1L cups.

Locations

For travel distances, the theoretical use locations were sites in the Netherlands.

Washing systems

Cup washing including transport, how cups are cleaned and additives used affects environmental impacts. How and where washing takes place depends on how and where cups are provided. Three wash systems have been analysed that account for most popular use scenarios:

Wash system 1 ‘Closed loop’: clean cups are delivered to the food service provider, used cups are taken away and washed using a commercial conveyor dishwasher for return.

Wash system 2 ‘Wash at venue’: cups are owned and washed by the food service provider on site. Washers used for this system are a single tank dishwasher 2.1 and glasswasher 2.2.

Wash system 3 ‘Bring your own’: customers buy, wash (using a domestic dishwasher) and return with cups.

Data and modelling

OpenLCA version 1.8. software was used for modelling and calculation of the impacts. Where appropriate, bespoke data has been obtained or measured. All other data has been taken from the EcoInvent V3.4 (2017).

Other environmental impacts

Analysis covering multiple environmental impact factors found the ZWC to be most sustainable overall

Benchmark study — GWP, CED and Water Use

“Analysis of the Zero Waste Cup showed it to be the most sustainable solution for hot and cold drinks overall.

The full study compared cups made with the new technology to both reusable (e.g. heavy plastic, glass and ceramic) as well as single use (e.g. PE lined paper, PLA lined paper, PET, PP and PLA) alternatives.”

Benchmark study addendum — ReCiPe covering 18 environmental mechanisms

“Zero Waste Cups came out as the preferred solution in a broad scope environmental ReCiPe study that covered the impact of popular reusable and single use cups across eighteen mechanisms”
