 Making material samples myself was the core part of the research process. It required making these (and actually many more) recipes, and trying to craft different physical forms to arrive at the important questions to ask biofabricated materials. Questions such as: when do you demould a bioplastic? How long does it take before it reached its final form and doesn't shrink anymore? Where does this recipe even come from? Is biodegradable necessarily more sustainable? Which factors makes a material sustainable? If it is sustainable, what other arguments might there be that make a material contested or controversial to use? 
 
-As a result of that process of making, wondering and questioning, [**a selection of 24 foundational recipes**](../outcomes/24_core_recipes/) is documented here, showing the research process, but also allowing anyone to start a physical sample archive with "new natural" materials. All these materials are easily and harmlessly absorbed by nature within 90 days and/or can be turned into compost, *without* controlled conditions that require industrial composting facilities. And/or the material can be re-used with no or little additional resources. Biodegradability as a sustainability label is too often used to greenwash e.g. disposable packaging materials, so these criteria were chosen as point of departure.

All of these materials are easily and harmlessly absorbed by nature within 90 days and/or can be turned into compost, moreover, most are home-compostable *without* controlled conditions that require industrial composting facilities following EU guidelines. And/or the material can be re-used with no or little additional resources.

 Three additional criteria were used to make the selection: it should be based on local abundance (ingredients sourced and/or produced around my location. Secondly, it should include a range of techniques, and lastly, these techniques should result in a variety of physical forms that makers and designers from different fields can recognize as semi-formed design materials.
