Seaweed, a diverse group of marine algae, is abundant and grows in oceans worldwide, from tropical all the way to polar regions. Seaweed thrives in a variety of marine environments, attaching to substrates like rocks and coral, and flourishing in nutrient-rich waters. Seaweed is categorized into three main types: brown algae (Phaeophyceae), red algae (Rhodophyta), and green algae (Chlorophyta). Each type has unique properties and uses. For example, brown seaweeds like kelp (Laminaria) are known for their rapid growth and high iodine content. Red seaweeds such as dulse (Palmaria palmata) are rich in proteins and vitamins. Green seaweeds like sea lettuce (Ulva) are nutrient-dense and are often used in salads. The rapid growth rate and minimal resource requirements of seaweed make it a sustainable choice for biomaterial production, contributing to its potential as a key player in addressing environmental challenges​ .

In the coming years, we will see material passports finding their way into various sectors, construction seems to be leading the way currently. These digital documents are designed to accelerate material reuse, promote deconstruction over demolition, and integrate a circular economy within construction practices.

This is part 1 of my thoughts on material categorisation!

Over the last few months, I’ve been thinking a lot about how we categories materials and how complicated this can be! I’ve been needing to categories materials for various reasons, for a database I am building, for workshops I am writing. All in the aim to make materials and what they are made of easier to understand.

On a very sunny but chilly Saturday morning I had the pleasure of visiting Margent Farm, a Hemp farm located in Cambridgeshire in the UK. Margent Farm opens up their farm and family home a few times a year for visitors. It was well worth the trip, to explore the farm, try bread dipped in hemp oil and I learn a few unexpected things about Hemp and the challenges faced by those farming it.
