| Abstract: | We characterise US materials exchanges by means of an exploratory survey, with 63 respondents classified by materials handled, organisation type and implementation strategy. Few respondents handle hazardous materials; instead, most focus on pre-consumer items such as building materials or post-consumer durable goods such as furniture. Non-profit organisations and state/local government agencies predominate in this niche, which fills a gap between ubiquitous for-profit scrap recyclers and used-merchandise stores. There are three distinct implementation strategies: passive listers of materials; active brokers, who become involved in each transaction; and those who take possession of materials for storage and display in a warehouse. Warehouse operations typically have a local focus and a loyal customer base, whereas passive listing services serve larger areas and are undergoing consolidation. Passive listing services appear to be relatively marginal enterprises, although the adoption of Internet technology is improving their viability. |
