An abattoir is a slaughterhouse where animals are killed and butchered for their meat. Modern abattoirs require pens to hold animals humanely, a slaughter area, and facilities to process the meat into portions and products ready for sale. Proper planning is important - an abattoir should be at least 500 meters from dwellings and have good road access. The minimum site area is 1800 square meters to accommodate all required modules laid out in a rectangular format.
