Are low transition temperature mixtures (LTTMs) the new designer solvents?

Many chemical processes need solvents, but their use is under considerable pressure. Many are considered unsafe and environmentally unfriendly. Solvents rank highly on the list of damaging chemicals because they are volatile and escape easily. These emissions cause losses of an estimated 6 billion Euros per year for solvent make-up, which is a strong incentive to minimize their use.
