GreenMantra Technologies, a cleantech company headquartered in Brantford, Ontario, recently announced it was expanding product offering to include a polymer additive for wood plastic composite (WPC) lumber.  The company calls the polymer additive Ceranovus.

“We are excited to offer the benefits of these additives to the WPC market,” said Carla Toth, senior vice president, sales and marketing for GreenMantra. “Industry trials combined with third-party testing validate that Ceranovus polymer additives generate value for WPC manufacturers who are seeking to lower overall formulation costs and improve operational efficiency.”

Ceranovus A-Series polymer additives can provide WPC manufacturers with both formulation and operational cost savings. And since they are made from 100 percent recycled plastics, Ceranovus additives increase the recycled content of a finished product, enhancing its sustainability profile.

GreenMantra’s Ceranovus polymer additives are also used in polymer-modified asphalt roofing and roads as well as in rubber compounding, polymer processing and adhesive applications.  Its Ceranovus A-Series waxes and polymer additives are certified by SCS Global Services as being made with 100 percent recycled post-consumer plastics.


GreenMantra utilizes catalytic pyrolysis to convert waste plastics to its various products.  A catalyst is a substance that initiates or accelerates a chemical reaction without itself being affected.  Pyrolysis is the chemical decomposition of a substance by heating that occurs spontaneously at high enough temperatures.  It takes place in the absence of oxygen so no combustion occurs.

Like other plastic-to-products companies, GreenMantra’s technology is propriety.  This is often the case since plastics-to-products companies keep information on the type of catalyst used, its optimum concentration, and operating temperatures of pyrolysis system closely guarded.

About GreenMantra

GreenMantra Technologies is the world’s only company creating high-value additives and specialty chemicals from waste plastics. The company’s products add value as processing aids by improving throughput and reducing manufacturing costs, and as additives through enhancing the performance of finished products. By creating value from plastic waste, we are helping to drive a more circular economy where plastics are beneficially reused rather than landfilled.

GreenMantra was incorporated in January 2010 and founded by Pushkar Kumar, a metallurgical and materials engineers who also has an MBA.
