Nano Crystalline Cellulose

Nano Crystalline Cellulose (NCC) is a primary building block of the cell wall of all living plants. NCC has high mechanical strength modulus of 150 GPa and tensile strength of 10 GPA in line with supreme synthetic material. NCC plays a major role in the structure of the cell wall giving plants their extraordinary strength exemplified by the gigantic dimensions of some forest tress such as Sequoia. This role can be adapted into man-made products utilizing NCC as a nano building block for the enhancement of existing materials and for the production of novel eco-friendly materials.

What is NCC good for?




Foams for composites
and insulation panels

NCC films for coatings
and optical properties

Gas barrier aluminum replacement
in food packaging

Displays







             
Reinforcing of paper
and paperboard

· Reinforcing of acrylic polymers



Additive to plastics
(biobased and synthetic) 

Additive to coating
and barriers materials

How to produce NCC?

NCC can be extracted from any plant material as well as bacteria and animals under controlled acid hydrolysis that lead to the formation of high-purity single crystals suspended in water in dimensions of 10-20 nm width and 100-500 nm length. 

Cellulose fibers contain amorphous and crystalline areas

Production of NCC from the fibers 

Melodea NCC production

We have developed a unique process that allows utilizing the sludge of the pulp and paper industry as the source for NCC. Pulp and paper mills sludge is produced in millions of tons worldwide as is both environmental and economic burden. A major component of the sludge is tiny cellulose fibers that are washed away during paper manufacturing. Our technologies allow the recovery of these fibers and convert them to valuable NCC product.

Main advantages of sludge as a raw material:

•Investment in fiber growing, collection and handling has already been done

•Most of the required energy and chemicals were already invested

•High availability, zero value

•Utilization of paper mills knowhow, infrastructure and utilities

•Paper mill sludge is converted into a valuable product

•Reduced carbon footprint of the industry 

We can also produce NCC from bleached pulp, and other cellulose sources such as flax and hemp fibers. We are currently enhancing our production capacity by establishing in Europe a production site with a capacity of producing 100kg/day of NCC (expected to be operative by the end of 2016).
