SYSTEM TECHNOLOGY DESCRIPTION

The KUG/NESNA Waste to Energy (WTE) Technology uses a biomass gasification system called "slow pyrolysis" and recycles tars, oils, and solids back into the process. This only then produces syngas, ash and char as products. The system has received favorable reviews from several independent technology evaluation bodies.

CURRENT STATE OF DEVELOPMENT

The most technologically and operationally advanced WTE system is the German designed KUG System. The KUG System is currently operating in a 4 ton-per-day Pilot Plant in Forst, Germany with a production scale facility constructed and operated in the past. The gasification unit has logged thousands of operating hours.

TECHNOLOGY AVAILABILITY

The KUG Technology is a core technology for use in recycling renewable energy systems by municipalities, agricultural and similar organizations that find themselves with excess carbon-based wastes. The technology can cleanly gasify wate products and renewable feedstocks such as tires, plastics, MSW and wood for electricity generation. These potential feedstocks are any renewable carbon-based waste and biomass available from a variety of sources.

The goal is to convert waste to electric or simliar energy at remote locations. The technology process and system inputs and outputs are suitable for use at remote locations and potential exists for global deployment.

ADVANTAGES OF THE KUG GASIFIER

Direct Injection of Syngas into Gas Turbine Engines - KUG Technology has been approved for direct use of synthetic fuel gas in a gas turbine. The use of unique gas scrubber design cleans the syngas to natural gas standards
Continuous Process - The KUG Gasifier processes feedstock continuously and produces syngas 24 hours a day. This is essential to provide fuel for engines
High Efficiency of Therma Conversion - The KUG Gasifier only uses 18 to 22% of its own fuel gas to drive the pyrolysis reaction leaving 78 to 82% of the energy for export. This is done with a unique multi reactor design that extracts all volatile gases from a feedstock before it exits the system
Feedstock Flexibility - The KUG Gasifier can convert all forms of carbon waste into energy. Rubber, plastic, MSW, biomass, auto shredder residue, waste oil, sludge, etc. There is no minimum size for feedstock and maximum size is two in² with a target moisture content of 20%
Natural Gas Quality Syngas - The Gaas Technology Institute of Germany has approved syngas from the KUG system as a replacement for natural gas. Syngas produced from various feedstocks have ranged from 500 to 1500 BTU per cubic foot in energy value
Flexibility - Uses include: power generation, LNG, hydrogen, alcohols, liquid transportation fuels, chemicals
No Tar Residue - The KUG system has internal tar cracking reactors that breakdown tars and use them to produce more syngas
Char Recycle - The KUG system operates at a low temperature enabling the char by-product to be recycled for its carbon content. The form of char depends on the beginning feedstock. Waste tires yield a carbon black char, Biomass yields charcoal or Biochar and plastic yields a coke char
Very Low Emissions - The only emissions from the process are syngas, char and burner exhaust. The emissions from engines burning the syngas are comparable to engines using natural gas. The system meets California air emissions standards
Low Pressure - The system operates at 50 millibar. There is no need for high pressure vessels keeping manufacturing costs low
Modular Construction - The system is delivered as a skid mounted module shortening construction and startup time. Modules can be added as customer energy needs increase
Multiple Models - There are five reactor designs ranging from 4 to 160 TPD making energy generation possible at remote locations near feedstock
Pilot Plant - KUG operates a pilot plant for actual project feedstock testing to optimize the design efficiency of each project
Experience - KUG has operated the pilot plant for over 20 years and has built a commercial scale plant providing technology scale up

NESNA Renewable Energy Products

Slow Pyrolysis gasification offers the possibility to produce energy from waste materials at a very high efficiency. NESNA has partnered with Germany based KUG and NEX Energy Systems Global (NESG) to offer a demonstrated non-combustion gasification technology to produce a high-quality syngas product with very high calorific value and no tar, dioxins or toxins. A multi reactor design and multi-stage gas cleaning system produces a high-quality syngas that is interchangeable with natural gas. Tests at the German pilot plant have been performed on all types of carbon-based waste feedstock demonstrating the reliable functionality of the KUG technology. The characteristics of the product gas (low nitrogen content, high hydrogen and methane content) allow many other uses of the gas. In addition to power generation, research projects concerning the production of SNG (synthetic natural gas), Fischer-Tropsch Diesel, Ethanol and H² extraction are successfully ongoing.
