FinnZa – Gate 5

Brief Technology Description

The Gate 5 Energy System (G5ES) is a highly scalable carbon neutral, thermal, non-incineration, process that can efficiently keep a variety of biomass and waste, namely; sewage sludge, fecal material, food waste and animal manure (together called “residuals”) out of the environment by transforming the residuals into renewable energy, potable water and other usable by-products without using fossil fuel or grid electricity. The G5ES dries and mills residuals into a finely powdered biofuel that is combusted in a biomass boiler. The heat produced in the process powers a turbine that generates continuously available renewable electricity in excess of the G5ES’s parasitic energy load.

Next Steps Required

FinnZa/Gate 5 want to prove the G5ES technology in South Africa and need to partner up with a wastewater treatment plant or industry producing problem waste with high calorific value, as well as potential financial partners. The first unit in South Africa will be build on a trailer in order to be mobile and will be able to be moved between test locations.  The G5ES will be manufactured in South Africa under license form Gate 5 Energy Partners and this unit can be as small as handling 7 wet tonnes per day, with no upper limit.

Company Background

It is a collaboration between two companies. FinnZa is a South African owned company operating in the renewable energy sector in Southern Africa. FinnZa and Gate 5 Energy Partners, Inc. are working to finalize an exclusive license for the use of Gate 5’s sustainable energy infrastructure in South Africa. Gate 5 Energy Partners, Inc. of Irvine, California, USA has been developing the live changing Gate 5 Energy System over many years and are now ready to roll out this technology worldwide.

Detailed Technology Description

The diagram illustrates a G5ES treating biosolids at a WWTP employing anaerobic digestion. However, the preferred feedstock for the G5ES would be primary sludge/WAS, which would produce significantly more sustainable energy than biosolids because of its higher latent energy content (~ 2x). The G5ES can easily be configured to operate on primary and waste activated sludge (WAS) alone or in combination with other residuals.



Energy Recovery

Sustainable Power Production

Technology Applications

Water treatment plants where sludge is accumulated.


Testing and Demonstration Results

Although there is no operational G5ES today, the design has undergone rigorous evaluation by multiple third-parties and has been confirmed by letter dated December 16, 2011 from Crystal Presley-Willis of the California Energy Commission, which in 2011 accepted Gate 5’s technology as “appropriate for industrial demonstration” (see appendix). The following summaries of G5ES technology assessments are provided:
