APPLICATIONS

CAPS & CLOSURES

PHA can be used for high performance caps and closures. We have an environmentally friendly solution for small packaging items that often end up in the oceans. Caps are in high demand worldwide, with the global plastic caps and closures market estimated to reach $39 billion in 2021.**

TEXTILE FIBERS

PHA can be formed into biodegradable biopolyester fibers for the $2 trillion fashion industry.* A sustainable a l te rnat i ve to pet ro leum-based polyester, our naturally occurring biopolyester can be used with other natural textile materials to produce a truly sustainable product.

TECHNOECONOMIC & LIFE CYCLE ANALYSES

TEA: challenges

•  Literature studies

•  Refining inputs at early-stage

•  Selecting platform for model

•  Working with partners on models

TEA: our model

•  Goal: show that we can be competitive with current polymers

•  Uses Excel

•  Easily modifiable

•  Demonstrates that our cost can be <$1/lb

•  Shows sensitivity to personnel, scale

LCA – Why haven’t we done one?

•  We haven’t needed to – yet.

•  When we do one, we want to do it well – and that’s hard.

LCA: we haven’t needed one – yet.

•  Focus on critical path

•  Investments to date haven’t required full LCA

•  Alternate environmental accounting

•  Mixed responses to LCAs

LCA: when we do one, we want to do it well – and that’s hard.

•  Expensive!

•  Quality of output depends on inputs

•  Difficult to fully define process at early-stage

•  Hard to account for scale-up (change in efficiency & equipment)

•  How to choose boundaries

What would help us complete these analyses?

•  Funding earmarked for LCAs for early-stage companies

•  Workshops/webinars geared towards start-ups

•  Guidelines for preparation
