A new website, Harvestmap (Oogstkaart in Dutch) at https://www.oogstkaart.nl is an online marketplace for industrial-scale redundant and second hand materials.

Harvestmap/Oogstkaart allows companies or individuals to list their supply of materials, components or even buildings to potential users. All materials, ranging from small quantities to continuous flows of industrial leftovers are represented.

Participation allows you to list your own supply, find available resources and provide tips to the community of users.

Oogstkaart, which is currently in beta, began in the Netherlands and has recently extended to the UK where material from the 2012 Olympic Park are listed.
