Attis Innovations’ primary focus is on developing technology that takes advantage of processing rapidly renewable plant-based energy crops and otherwise low value agricultural byproducts for conversion into higher value products. Attis has evaluated many forms of agricultural and industrial biomass and believes it has identified an untapped component within each, lignin, that is expected to have a significant impact on multiple markets.
Lignin is a natural polymer that is present in all vegetation sources. Lignin is one of the most abundant natural plant-based polymers on Earth, second only to cellulose, and if recovered effectively, lignin’s unique properties allow it to compete in value and usefulness to that of fossil fuels.
Lignin is the component within all plants that protects and provides structural integrity to the plant’s cells and is inherently very difficult to efficiently isolate and recover. Generally speaking, traditional pulp and paper producers and cellulosic fuel producers have historically viewed lignin as a hindrance as they have found it to be expensive to extract, purify and convert into useful products. Most cellulosic ethanol and pulp and paper producers elect to simply burn the lignin as a low value energy source.
Attis is looking to capitalize on this waste stream by deploying what it believes is the most advanced lignin recovery process in the market. The process will play a vital role in enabling businesses and industries to capitalize on lignin’s boundless untapped value.Traditional Lignin Recovery Technology
Lignin and lignin recovery is not new; however, currently available lignin recovery methods take the partially abused lignin that exists in byproduct streams of pulp, paper and cellulosic fuel production systems and unfortunately abuse it even further as they recover and attempt to purify it into a usable form. These ineffective recovery methods damage the usefulness of what was once an incredible natural polymer.Attis Innovation’s Technology
The Attis lignin recovery process is unique in that it more delicately extracts and purifies lignin. In doing so, the resulting recovered lignin is a meltable thermoplastic material. This melt flow characteristic is unique to Attis and has not been demonstrated by any other known recovery method.
Additionally, during the Attis process, functional additives can be introduced in situ that allow the lignin to perform better in a myriad of applications.
Even more impressive is that Attis’s highly efficient recovery systems require significantly less capital than the highly abusive lignin recovery systems that precede it. Attis is opening the door for industries to capitalize on lignin’s impressive properties and cost effectively introduce bio-based content into their portfolio.Scalable to as low as 200 Tons per day Biomass Input
The Attis technology is uniquely scalable to allow cost effective processing at flow rates as low as 200-tons per day.
To put this in perspective, fifteen-thousand-acres of farm land can often supply enough woody biomass or residual crop residue to supply a 200 ton per day Attis system.
The opportunity to process at small capacities allow cost effective processing of many agricultural byproduct streams such as bark, sawdust, pecan shells and rice hulls.
Attis’ ability to process at small scale not only opens the door for new lignin-based materials but also allows for the introduction of new pulp fibers that otherwise could not be recovered cost effectively. As most pulping facilities require massive economies of scale to justify the capital intensive one-hundred-year old processing technologies within; they often require input feed rates in excess of three thousand tons per day. This eliminates a vast majority of biomass opportunities and therefore eliminates the ability to source uniquely desirable pulp materials.
Summary of the advantages of Attis Innovations' lignin recovery:
- Low CAPEX
- Low OPEX
- Highest Lignin Quality (meltable thermoplastic material)
- Scalable down to 200 ton per day systems
- Significant increase in the revenue generated from biomass
