[Stoves] Biogas backpack

[Paul Olivier]

A.D.

In many developing countries in Asia food waste is routinely collected from
large cities and fed to pigs.
Very few cities in Asia are predominantly vegetarian.
BSF larvae, in any case, do not require meat in their diet.
In fact if there is too much meat, this is not good for larval growth and
development.
Rearing larvae and red worms do not attract vermin and other creatures,
because these creatures have no access to the site.
I suggest that you read carefully what I have written on pigs, BSF larvae
and red worms.
Also keep in mind that cultivating pigs, BSF larvae and red worms are not
the only strategies one might employ to keep food waste within the
food/feed chain.

Thanks.
Paul
