Polyhydroxyalkanoates (PHAs) are a unique class of biobased and biodegradable polymers produced through microbial fermentation of sucrose. Unlike conventional plastics, PHAs break down naturally, making them an environmentally friendly alternative to traditional plastics. 

Chematur is the exclusive global licensor of Bioextrax PHA technology. The process is an entirely biobased process where PHA is produced in a fermentation process and then extracted biologically in a patented cost-effective method. The unique features of the technology are: 

• it is completely bio-based, free of chemicals and solvents 

• it is universal, can work with all PHA producing bacteria and with all PHA types 

• it has higher biodegradation rate compared to other bioplastics 

• it produces intact PHA granules, without molecular weight loss and with native amorphicity. 

• it is a unique and GMO-free process, which increases the conversion rate between sucrose and PHA, allowing for a significantly lower production cost for PHA. 

• it offers a low production cost through low consumption of energy, water and chemicals. 

it produces valuable co-product: Single- Cell Protein (SCP), which has high commercial potential in applications such as animal feed, human nutrition, and other industries.

Chematur’s DNB technology is less complicated to our well-known and well-proven pump-nitration technology for DNT. As benzene is far less reactive than toluene during the nitration, the DNB process is a safer and simpler than the DNT process.

Chematur’s pump-nitration technology is inherently stable and operates at a point where energy needs to be added (by pumping) for the reaction to continue. Excessive heat is rapidly removed from the system by inline coolers. A state-of-the-art control system monitors all important parameters continuously, and process interlocks will shut off the process if any deviations are identified. This is the safest nitration technology on the market.

Chematur’s (patented pump-nitration) technology for the di-nitration of toluene is a well-proven technology, with more than 10 plants built. Additionally, Chematur possesses extensive experience in the tri-nitration of toluene, which is a slightly different yet related technology.

Chematur’s pump-nitration technology operates at a point where energy needs to be added (by pumping) for the reaction to continue, making it inherently stable. The system efficiently removes excessive heat through inline coolers. A state-of-the-art control system continuously monitors all important parameters, and process interlocks are in place to shut off the process if any deviations are detected. As a result, this technology is regarded as the safest nitration technology available on the market.
