Just bought box of Ecover powder. Jolly good, less manufacturing than tablets (or am I deluding myself there?), no plastic wrappers, and easy to use less for smaller washes and soft water.
But.
Powder box is full volume and weighs 1200g, yielding 12 standard washes (100g per wash).
Tablet box is about 3/4 volume and weighs 960g, yielding 16 standard washes (60g per wash)
So the powder is at least 65% more fuel-expensive per wash to ship from Europe where it's made.
WTF? Is there some reason powder can't be made of tablet stuff, just loose? (God knows it reverts to powder fast enough in an opened wrapper.)
