The design team

"Delivering precision, collaboration, and clarity at every stage of your project. Our expertise ensures integrated design and seamless coordination for successful outcomes."

who are we?

Since 2022, the Bio-Drive Design Team has been advancing the anaerobic digestion industry with high-quality CAD and engineering solutions. Starting with William Crewe-Turrell and Josh Mold, and joined by Mariangela Velasquez de Spirito in 2024, the team combines precision, creativity, and sustainability. Together, they integrate advanced design with optimised processes, delivering efficient and environmentally conscious solutions for projects ranging from large-scale to small-scale systems.
