The self-made multi-millionaire's life in the region started when he moved to Worcester in the 1950s. He built up the successful Worcester Heat Systems business, which was bought by Bosch in 1992, before turning his attentions to the rugby club.
Mr Duckworth was previously awarded the OBE for services to rugby and the community and was made a Freeman of the City of Worcester in 2008.
He is one of the original benefactors of the city's Acorns Children's Hospice and is a founder of the Duckworth Worcestershire Trust, dedicated to the conservation, protection and enhancement of the natural and built environments for the people of Worcestershire.
Mr Duckworth said: "On this occasion it was wonderful to receive my CBE from the Princess Royal at Windsor Castle, where only a few presentations are made.
I was absolutely delighted when the Princess Royal immediately recognised me and commented that the honour was well-deserved.
"She is very involved in rugby and Wooden Spoon and visited Sixways in November 2009 so it was fantastic to see her once again.
"The CBE came totally out of the blue but I am obviously delighted to be awarded this rare honour."
