摘要
A survey of major chicken meat hatcheries in Australia was undertaken in 2008 to identify how hatchery waste is currently managed. A weekly average of 10.4 tonnes of waste is produced by chicken meat hatcheries. The cost of disposal （average $127/tonne） and availability of disposal sites is an emerging issue. The majority of hatchery waste is sent to land fill or for composting, with some rendered for use as pet food. Hatchery wastewater is mostly used for irrigation or disposed directly into the sewer. Most of the hatcheries have no environmental issues with hatchery waste on site but some report odour problems. Some hatcheries would like to treat the waste on site so that it could be sold as a commodity or to use methods to separate liquid from solid waste and recycle water.
