About 15 years ago I decided to prove that Japanese Knotweed could be composted. I very carefully took a bin bag full from some waste ground and chopped it up into a 600 litre tumbler where it got very hot with shredded hedge, roadkill and waste bread. It decomposed just the same as any other plant.

However I would not recommend ordinary (or law-abiding) composters to do the same. I was extremely careful and did it just to prove a point.
