Bio-Content Analysis

Bio-Based Content

* BioBlack® toner is made using a bio-based resin with a proprietary patent-pending toner formulation. The bio-based resin in turn is made using various agriculturally derived materials, which may include corn, cottonseed and soy. Analyses run by an ISO-17025 accredited independent laboratory using the ASTM-D6866 method showed that the bio-based content of BioBlack® toner is as high as 34% (Different cartridges may require different toners with different bio-based content levels, some of which may be lower than 34%).

Petroleum Usage

While the ASTM-D6866 method cites a precision of +/-3%, these results indicate that the amount of bio-derived carbon in BioBlack® toner is far greater than the OEM (0% for HP® 4350™ and P2015™, tested in April 2009) for the same amount of carbon in toner.

The ASTM-D6866 method is similar to the radiocarbon dating method, which measures the amount of carbon-14, which exists in bio-based materials, but is non-existent in fossil-based materials such as petroleum.
