[Digestion] Digestion of Honey Waste

[Duncan Martin]

A wide variety of packing materials can ve used a substrates for microbial
growth in an AD filter.

A bed of limestone (or any rock) is cheap and would work well but-  would
have a low voidage (~35%). This would make the digester ~3 times bigger,
which would cost a lot more. It would also be a lot heavier.

The best packings are manufactured plastic shapes, which are stable and have
over 90% voidage.

Scrap materials could be used instead - much cheaper but a larger volume
would be needed to get the required surface area, so again the digester
would need to be bigger. Again, the net cost would probably be higher.
