Hi Eugene,

Not sure you have heard about these companies:

  • Be More 3D: From Spain but technology has been used in Africa
  • 14 Trees: a joint venture between Swiss-based building material manufacturer, LafargeHolcim, and the UK’s development finance institution, CDC Group.
  • Icon (US based but have worked with non-profit New Story to provide shelter in Mexico)
  • Apis Cor (designed by Russian engineer Nikita Chen-yun-tai)
  • Wasp (Italian based. Might be higher price wise) 
  • Not sure if this company could be interesting for your project: Winsun 3D Builders
  • This organization thinking huts created a school pilot. 
  • Cobod. Europe based

This news article features a list (including some companies mentioned above) of 13 house construction 3D printers.

There are also companies working on building affordable homes with recycled materials. Let us know if you would like to know more.

Water hyacinth is a major problem invasive plant.  Are there any examples of where the plant is used successfully in a circular economy or high impact project?

Hello, yes we have made thermoplastic composites using the protein fraction and fiber cellulose as reinforcing agents. Our company ALGIX uses algae and macrophytes, such as water hyacinth, to displace oil and plastic in consumer products.  You can check out our website at www.bloomtreadwell.com

Hi Barbara,
Thank you Peter Schelstraete for linking.
Indeed we just started working on a 3 year project "From plastic soup to veggie soup" in the UNESCO Waddensea area. It is focused on reducing plastic use and developing biobased products. The products are designed by regional creative product designers in cocreation with SMEs, students and inhabitants in the region. The idea is to develop nicely looking icon products inspired on regional elements, together with people in the region so people are proud of these products. We work with farmers to enhance the use of rotating crops use for product to help the biodiversity, or use agri waste. We create open source maker industry workspaces, educate smart hands, attract launching customers, advise legal authorities on their policies and set up circular business models.
Our working method is called The Local Value Chain which we developed the last few years working on projects in preserving crafts in Europe, circular design education, bio based design, sustainable design festivals, inclusive design, etc.
Hope this will help a little on how we work, if you would like more info, please let me know!
yrs, Eileen
