Miss Hoyle said: "I'm so excited about the show, I've done a few beauty pageants but this one is the most important to me. It's a really well-known event and the best thing about it is that it also fits in with my philosophy about being green."
Young women from England, Scotland, Wales and Northern Ireland will be vying for a chance to represent their country along with more than 100 others at the world finals of Miss Earth, one of the biggest international beauty events.
"The thought of being up there answering questions is quite scary and I've got to prepare an outfit made out of totally recyclable materials, which I think I'm going to enjoy," said Miss Hoyle.
Brother Alex, 16, and parents Terry, 68, and Gwen, 55, will be making the trip up the M1 to support their daughter.
Miss Hoyle, a nursery practitioner, said "All my friends and family are up for coming up so it will be pretty spectacular if I win. My brother has taken a keen interest too, now he has realised the amount of pretty girls on show."
Finalists organise tree planting events and get involved with community projects through Girls4Trees, which gives funds generated through the Miss Earth final to UK projects.
The winner will receive prizes including a collection of Aqua Green Eco swimwear made from recycled material, a photoshoot, five outfits from Tcharakoura, a wardrobe of gowns to wear at the world final, Earthnicity natural cosmetics, an Annibee eco bag and a makeover.
Along with the title of Miss Earth the overall winner will have the opportunity to work as an ambassador for environmental protection campaigns worldwide and promote animal protection and environmental awareness.
