Converting biomass into urea fertilizer

Biomass technology can be used for various useful purposes because there are different conversion methods enabling production of various useful materials. One of the very interesting new technologies comes from Florida-based BioNitrogen Corp.

This company patented its brand new technology which enables them to convert biomass feedstocks into urea fertilizer.

The company announced that this technology is capable to convert 1,000 tons of residual biomass, among other also sugarcane bagasse, palm waste, corn stover and rice hulls, to produce 520 tons of granulated urea with 46 percent nitrogen content.

In the process of conversion biomass gets dried, cleaned, ground and then gasified which leads to production of synthetic gas (syngas). Once the gas is produced it gets cleaned and is afterwards processed through catalytic reaction stages to produce the fertilizer.

It is also important to mention that any byproducts of the vent streams are recycled back through the system to produce electricity and 60 tons of ash, which is sold as a concrete additive.

Bryan Kornegay, president and chief financial officer of BioNitrogen said how "this patent is a key intellectual property asset and the one that significantly enhances our competitive position in the marketplace.”
