Cedar Rapids Gazette: A Coralville company that filed for bankruptcy protection amid a dispute with its lender has let go 40 employees. Zero Energy Systems laid off its entire production staff effective today. More layoffs are expected as the company winds down operations, the company announced on Monday. Zero Energy, which makes insulated concrete walls, filed for bankruptcy in late March after Iowa City-based MidWestOne Bank sued the company. The bank claimed Zero Energy had defaulted on its loans and owed the bank more than $16 million.
