Hi Mr. Isaac,

Thank you kindly for taking the time to complete and share your proposal for Ecovon here. Personally, I love your combination of creating a more sustainable building material while also providing a new revenue stream for the coconut sellers of Ghana.

Question - are there any structures currently using your materials? 

Also, I found your informational video on YouTube showing how you make the new boards. Sharing it here so others can benefit from it as well - 

Best of luck,

Hello Drew

Thanks for the awesome commendation and the comments you made on my project. I hope that you will share Ecovon You tube video on your social media networks and other platforms to help Ecovon gain international recognition, support and funding from climate change related organizations and investors interested in funding green startups. Thank you

Regarding to your question, Ecovon have given samples of our prototype to furniture producers or carpenter for their applications and the feedback were amazing. Thank you

How large is the supply of raw materials (coconut husk and bagasse)?  I understand that it would be a good problem to have but what happens if you run out of raw materials due to demand for your product?

Also, are there any comparable/competing products on the market now?

Very interesting idea,

Hello Toby

Out of the annual national production of 224 million nuts, 179 million (80%) were produced by smallholders from an area of 36000 hectares (Arkhurst 1991). Ghana is the 16th largest producer of coconut in the world and also has 0.6% of the world share; Ghana also produces 366,183 tons in 2013 according to fact fish from Food and Agriculture Organiztion (FAO).
Ghana is also one the leading countries in the production of sugarcane in the world and as such Komenda sugar factory was constructed as result of Ghana endowment in sugarcane farming

The competitors of Ecovon project will be wood-based particleboard and fibreboard and others for building and construction or for other purposes

Dear Isaac, 

Similar to Drew's original question what are examples of these coconut and sugarcane based biomass materials being used in industrial applications? What are the barriers to allowing the rest of industry to also use them in other applications within building materials and energy uses? For Example:

  • Cost 
  • Material Properties needed for various applications that these materials do not meet certain requirements for 
  • lack of education on these materials in their respective markets. 


I would provide additional information about each of these within the challenges portion of the proposal. 

Best Regards,

Hi Isaac Brenya,

Thanks for submitting a proposal to Climatecolab challenge. I understood your proposal in more detail by going through the video shared by Drew Depriest above. I recommend you to add a few images to the proposal so that readers can relate to your description. I think the proposal is good & scale able. 

Thanks & regards
