Another variety is the green technology development park, where the emphasis is more on the sharing of knowledge. Another common EIP is the kind organized around materials recovery (e.g., a Resource Recovery Park) or around another anchor facility, like a core industry or infrastructure facility for wastewater treatment or energy production (Lowe, 1997). Some of the anchors are large industrial enterprises, while some parks are oriented much more to small and medium-sized firms. Some parks are privately owned and run, some coordinated by the state.
