Paper waste sludge (PWS) is merely a waste of paper industry. PWS contains a large content of pulp cellulose but almost cannot find any valuable application. Without appropriate treatment, PWS cannot be disposed to the environment because it can be bio-dicomposed and fermented that makes ordor smell and organic polution. In our solution, PWS is hydrolyzed with a small amount of acid, then fermented to form thick layers of bacterial cellulose (BC). BC can be collected easily from the fermentation mixture. This is a valuable materials that can be applied for many applications, such as in bio-material synthesis, medical, water treatment processes, packaging, fashion, etc. Some well-known superior properties of BC are biodegradable, good mechanically durable, high biocompatible, non-toxic, etc. To illustrate a potential usage of BC from PWS, we partially hydrolyzed it to obtain nano crystal cellulose (CNC), which is currently known as the most advanced bio-material in the world. CNC is stronger than steel, lighter than wood, transparent film formable, biodegrable, non-toxic, etc. Basic analysis confirmed the feasibility. Although Biomass is in early stage, we already have customers like Anbinh paper industry and Mitsui Chemicals Qroup.

Biomass has taken advantage of waste from the paper processing industry to create new biological materials, which are highly applicable in industries such as: Bio-plastics, Paper, textile, Membrane technology, Nano Tech, Sustainable Packaging. And this radical technology is pending for intellectual property right. With a huge market size not only in Vietnam but also in over the world, when special industrial waste from industries such as paper and fashion are all a big problem globally, this solution brings a breakthrough biotechnology, we can see this solution to make the world a better place for a green planet. In addition, the business model of the enterprise is oriented to the production of raw materials as input materials for plastic enterprises, equipment manufacturing, etc.
