treeseed Brownfields are abandoned, idled, or under-used industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contaminations.
In city planning, brownfield land (or simply a brownfield) is land previously used for industrial purposes or certain commercial uses that may be contaminated by low concentrations of hazardous waste or pollution and has the potential to be reused once it is cleaned up. Land that is more severely contaminated and has high concentrations of hazardous waste or pollution, such as a Superfund or hazardous waste site, does not fall under the brownfield classification.
In the United Kingdom and Australia, the term applies merely to previously used land.
