The bank holding the bonds issued for the failed Mamtek project in Moberly is suing the company for $36 million. UMB Bank is holding the bonds because the city has defaulted on them. The bank also wants a receiver to be appointed to take over company assets before they can be sold. Mamtek planned to build an artificial sweetener plant in Moberly but the operation fell apart with a building only partly built and no jobs created. Mamtek has assigned its assets to a company to sell them.
