 "sustainable carbon-banking bio-based material systems for the circular economy"

Coobio Circular Materials develops and manufactures high-value engineered solutions for the construction industry using bio-based by-products and co-products from the agricultural industry.

A key driver for using bio-based materials is the need to decarbonise the construction industry.

Coobio manufactures LigniCell Compressed Straw Board (CSB). This is a unique, high-performance, load-bearing board with great acoustic and thermal properties, extremely damage resistant, made entirely from compressed straw.

LigniCell can be used as internal partitioning or as part of high performance external wall build-ups.

In partitioning LigniCell:

  • replaces plasterboard
  • is extremely damage resistant
  • replaces stud work framing
  • has exceptional acoustic performance
  • is faster to install
  • can be supplied to any length up to 3.2m
  • no special fixings required
  • reduces waste
  • reduces cost

Coobio is innovating for the construction industry and will play a role in reducing emissions and improving energy efficiency.

Our LigniCell boards and partition systems are part of the solution.

Many architects and homeowners are convinced of the performance and long-term financial benefits of bio-based materials in construction. 

Our LigniCell bio-based insulation board and partition systems have much lower “embodied energy” levels compared with more conventional building materials.

Our source material is waste straw, which itself sequesters atmospheric carbon dioxide via photosynthesis.

“The beauty of bio-based materials is that they are often a byproduct of growing our food. We can build with carbon. Instead of seeing carbon as a problem, we can recast our relationship with it to one of positive innovation”, says Craig White, director of White Design

How it works:

LigniCell is formed by the application of heat and pressure to cellulose materials:

Heat causes naturally present moisture to be turned to steam.

The lignin which forms 25% of cell walls of all plants is liquified and the long chain molecules act as a bonding agent.

Pressure forces the materials together into a self bonded whole, thus straw becomes a load-bearing board.

After cellulose, lignin is the second most abundant renewable carbon source.

 

Coobio's LigniCell products are a step towards decarbonisation of construction. In Europe, households are responsible for 32% of greenhouse gas emissions and 42% of energy. Cement production alone contributes to 5% of manmade CO2 emissions.
