In Alaska there has been little or no market for the fish waste produced by the fish processors and in some cases it has become  an environmental problem. Each year Alaska produces 1 billion lbs (454 million kgs) of fish of which approximate 1/3 is waste in ther form of the head and guts, and it's tipped back into the sea. In Kake this will now be turned into biogas, RNG and ogrganic fertilizers.

Biogas  will add an additional $800,000  a year to our income and create 16 new jobs in Kake

Global NRG is able to extract the CO2 from biogas so that it has the same methane content as natural gas (RNG or Renewable Natural Gas) that can then be used as not only a heating and cooking fuel, but also as a transport fuel, for generating electricity in remote villages and possibly an alternate fuel for the fishing boats.

The  process also produces a nitrogen rich water as a by-product and a nutrient fertilizer, both of which will be used in the greenhouses

Producing biogas involves what otherwise would be waste product, so it is a positive gain for all concerned.

How biogas is manufactured

Fish waste and other organic matter are fed into temperature controlled digesters in the absence of oxygen where they are fermented. During the two stage fermentation a methane gas is given off which is captured, cleaned and stored ready for distribution.


Biogas is used for cooking, generating electricity, heating and as a transport fuel.

Using biogas for cooking in Kake will drop the cost of living, the gas can be used as a transport fuel, as an alternative to diesel, for generating affordable green electricity in other remote villages cutting the State government's need to subsidize electricity prices.
