How do abattoirs typically treat and dispose of their waste streams
(solid and liquid)?

Hi! Thanks for the question.

Our first link provides a description of the different waste
treatments for abattoirs or slaughterhouses. This is a very important
link since it discusses the basics of waste treatments for abattoirs.

Recycling - "Composting of solid waste such as turned windrows and
aerated static pile are most suited to the treatment of meat plant
waste."

"Disposing of industrial solid waste is arranged in several ways,
including disposal to the local council's landfills."


Biofiltration - "Biofiltration is very effective for managing odour
problems. All odorous gases are released underneath the ground to a
biofilter bed. The biofilter bed is constructed of materials such as
concrete, blockwork and earth, and the beds layered with products such
as compost and rice hulls, coarse gravel, sand, pinebark and
woodchips. Microorganisms in the bed break down organic and inorganic
odours in aerobic microbial activity under damp conditions
(humidification of odours)."

Incineration - "Some abattoirs may wish to dispose of sludge and other
wastes by incineration. Coal fired boilers may also be used in the
rendering process. All fuel burning equipment will release greenhouse
gases."
