Bio-based synthetics are NOT free from fossil fuels

Plus, communication examples and a reading list that will make you a pro in no time.

Welcome to The Crisps–your weekly newsletter on anti-greenwashing and honest fashion communication. In this issue, let’s get into greenwashing examples and myths about bio-based synthetics.

Whenever we talk about fossil fuel-based materials in fashion, we’re faced with three perspectives. Some ditch synthetics altogether. Some plea that they can’t go without them. Others swear by bio-based synthetics as THE solution to cut the dependance on fossil fuels.

But in the discussion around which material is best, critical aspects are missing. We rarely talk about the coal burned to produce heat for dyeing, drying and other processes or the fossil fuel-derived inputs used in material processes and finishes. Those are used whether it’s for synthetic fibers, natural materials or bio-based synthetics.¹

Last week, we touched on where fossil fuels are hiding in the fashion industry (in case you missed it, you can read it here). This week, we wanted to share what a “fair” phase-out of fossil fuels in fashion could look like. While writing this issue, we realized that the phase-out of fossil fuels needs an ENTIRE issue on its own. So we are preparing it for another day where we will dive ultra-deep into the topic. Pinky promise!

For this week, we look at myths about bio-based synthetics and share some greenwashing examples of “preferred synthetics” with you. Plus, we’ve curated an additional reading list with trustworthy sources that will make you a pro about fossil fuels (in fashion) in no time.

3 myths about bio-based synthetics

1. Myth: All bio-based synthetics are “eco-friendly”.

Reality: Not necessarily true. While bio-based synthetics can be derived from renewable resources, the overall environmental impact depends on various factors such as cultivation practices, processing methods, and end-of-life disposal. Agriculture for bio-based feedstocks can involve changes in land use, water consumption, and the use of fertilizers or pesticides. Additionally, processing methods and transportation contribute to the overall environmental footprint. While bio-based materials aim to be more sustainable, it’s important to understand that they can still have negative environmental impacts.²

2. Myth: Bio-based synthetics are biodegradable in all environments.
