Single-handed sailing circumnavigation, as it was contained within the southern hemisphere; however, he made the first single-handed passage of the three great capes, and indeed the first successful single-handed passage of Cape Horn. With only three landfalls, Vito Dumas described the legs of his trip as the longest that had been made by a single-hander, and in the most ferocious oceans on the Earth. Organised single-handed yacht racing was pioneered by Britons "Blondie" Hasler and Francis Chichester, who conceived the idea of a single-handed race across the Atlantic Ocean. This was a revolutionary concept at the time, as the idea was thought
Single-use bioreactor will be continuously reused. The plastic bag that is used instead of a culture vessel is a disposable, as well as all the integrated sub-assemblies like sensors, tubing, and stirrers. The bag and all its parts are mainly made from plastics that are derived from petroleum. Current recycling concepts are mainly focused on incineration, to recover the energy originated from the petroleum as heat and electricity. Most of the petroleum would be burned anyway in power plants or automobiles (citation required). Burning of the single use components of bioreactors creates a detour through biochemical engineering during their life cycle that
