Deepdives | SYMBIOSIS festival 2021

DWGWD (148 of 187)

Symbiotic relations emerge in good conversations. That is why we organize 6 deepdives during SYMBIOSIS festival 2021 on the 19th of November, connected to themes that entrepreneurs, partners and designers in and around BlueCity work on. You are invited to be part of these conversations. Get your ticket and reserve your seat at one of these coversations at the entrance of the festival! Be on time, since we have limited capacity per conversation. The deepdives take place from 3.30 to 4.30 pm.

Contradictions in chemistry: God-given or man-made?

Arie Hooimeijer (PaperInnovator), Lori Goff (Outlander Materials) & Barbara Schrammeijer (University of Applied Science).

The EU single use plastic ban says that something is made from plastics when a polymer does not occur in a natural ecosystem. Only polymers are allowed which are made by nature. This means PLA is not allowed under the European plastics ban. How can circular chemistry, or even bio-circular chemistry play a role in finding solutions for this wicked problem? When nature makes a polymer, it is allowed, like chitin. Synthetic polymerisation: when it is done in a bioreactor would not fit within this legislation. Join the conversation to connect with fellow professionals on this topic and together get a better understanding on what needs to be done and who can play what role.

Regenerative seaweed production & supply chain

Marjanne Cuypers-Henderson (BlueBlocks), Anne Boermans (Zeefier) & Kelp Blue
Seaweed as a resource for products provides answers for many major questions: since we can grow seaweed in coastal areas, it offers additional space to the areas of land we currently use for renewable resources and food production. Also, the applications to replace chemical fertilizers, plastics, food, feedstock, fibers and pharma are immense. The challenge is to organize the production chains in such a way that biodiversity is not harmed, but supported. How can we organize this from the very start of the seaweed economy in a regenerative way, and what is needed to accomplish this?

Using invasive species as resource 

Jos Poolman (Rotterdam University of Applied Science) & Charl Goosens (VARTA LAB)
River lobster from the Americas, Japanese knotweed and Giant Hogweed: there are several species that are already quite dominant in the Dutch ecosystems. The action group Stop Invasive species works on reducing this dominance to give back space to ingedinous species. Yet there is also a call to embrace their power and use them as a resource. The Giant Hogweed could provide beautiful resources for the pharmaceutical industry for instance. How can we better collaborate and what is needed for this?

Hemp Economics

René Sauveur (Pantanova), Joost van der Waal (Ecobouwschool) & Dyveke Kok (HempCollective)
The excellent potential of the hemp plant as a green material – it has been in the spotlight for quite some time now. The reason being for the numerous useful possibilities provided by the plant (textile fibers, food, oil, building material), as well as the amazing quality of the fibers and the benefits the plant can bring to the environment and the soil. Yet, the plant still fights against an image of being “drugs” and the current Dutch and European legislation prevents whole cropp valorisation. How can the hemp economy get back into business and how can different actors collaborate in a better or smarter way?

Products from the wetlands: connecting city and agriculture

Klaske Postma (VanHier), Emma Raaijens (FlipTheCity) Marloes Arkesteijn (Province of South Holland)
In all peatlands around the world, there is a severe problem with prolapsing of the soil. This causes leakage of CO2 from the peat into the air, and causes damage to the fertility of the already sour lands as well as to the cities and villages built on these peatlands. There is one systemic solution that is found by scientist in the past twenty years: reswamping the peatlands. This entails a drastic change for the existing entrepreneurs (farmers!), landowners, flora and fauna. There are stronger collaborations needed to speed up this change and to investigate how hinterland and cities can better collaborate to find new income models, new products and application of current organisms from these wet peatlands, such as cattail and duckweed. Two entrepreneurs from BlueCity work on products from these sources. Join when you are already working on this challenge, or when you are interested in how you can become part.

Biocircular textiles

Richele Wind (HAN Biocentre), Anna Wetzel (designer and volunteer @The Linen Project) & Michiel Scheffer (professor @ Wageningen University)
Traditional ways of making textiles gain popularity again since these save water, resources and lots of chemicals. One of the interesting projects of the past years is The Linen Project: a community of stewards growing flax in Arnhem and processing it together into linen, investigating in the process how their practice influences their perceptions of value and their relationship to ground, material and physical labor. What insights emerge from these practices? How does this relate to the fact we need to scale up and aim for rapid transformation of the fashion industry? And what role do enzymatic processes have in bringing back textile production in Europe & in our region?
