7.2. Design and operation of fly biodegradation facilities
Another important issue which must be considered is the large amount of heat and volatile by-products that are released during the most intensive phases of biodegradation. The difference between the temperature of substrate with larvae and ambious environment may be as large as 12.5 °C (Zvereva, 1984), which places substantial demands on the air conditioning system.
To provide additional security for the biodegradation facility, egg-production and biodegradation areas could be separated into smaller subunits, for example each with a processing capacity of 1 t of raw manure. Such structure would allow easier management of some potentially serious problems, e. g. infectious fly diseases or invasion by parasitoids which could seriously threaten fly colonies. Independent management of these subunits would allow convenient quarantine of affected areas with little impact on the remaining operation.
