Fish?

We are also planning on building an ornamental fish farm.

The effluent from the digester, which is a nutrient rich liquid that drains out the side, can be diluted and added to the water the fish are swimming in to improve their environment.

If this is successful, and the fish survive, then they can be sold as a source of revenue.

Crazy united statians and their fish-fetishes.

I guess they are pretty...

What is a BIOGAS DIGESTER?

When I tell people I am going to Peru to build a biogas digester, they always want an explanation.

What is it?
How does it work?
WHY?!

I can answer some of these now, but by the end of the trip I should be able to give a better account.

What/How/Why?

A Biogas Digester is basically an airtight tank of biodegradable material. Through a process called anaerobic digestion (WITHOUT OXYGEN) this material decomposes at a relatively fast rate, producing METHANE! The methane can be collected from the top and subsequently burned as a cooking fuel.

This not only provides a sustainable source of fuel, but the sludge leftover in the tank can be used as a Nitrogen rich fertilizer. Plus it helps control waste build-up near dwellings.

Cool!
