The investment has helped the Worcestershire business boost its facility by a third, with an additional 15,000m2 added to the site.
This will help the firm grow its mushroom sales from its current output of 500t a week.
Although no new jobs would be created initially as a result of the investment, it could lead to jobs later, a spokesman for Walsh Mushrooms told FoodManufacture.co.uk.
‘Vital for growth’
The firm’s md Padraic O’Leary said the investment was “vital” for the long-term future business in “order to grow the business that has been in Evesham for over 30 years”.
The investment also included £160,000 on solar panels which would provide 60% of Walsh Mushrooms’ electricity requirement.
This is in addition to the £225,000 spent on the existing building earlier this year, the firm said.
