Improving the beneficial use of waste material from a vegetation source, a biomass is fermented to produce a bio-fuel and carbon. The bio-fuel can be at least ethanol and bio-diesel and the resulting carbon can used to produce ink for printers. When the biomass is tree matter, a biocatalyst can extracted from the tree matter prior to fermentation. A component of the biocatalyst is used to cleanse internal combustion engine exhaust emissions by spraying the biocatalyst onto a exhaust emission gas. The sprayed exhaust emission gas can be filtered and the filtration by-product can be collected.
