Key points to the law and Japanese knotweed disposal:


Landfill: the landfill operator must be licensed to take Japanese knotweed, Landfill operators are regulated and have to comply with legislation; they need to understand the nature of waste and normally require material to be lab tested (soil test) which can take several weeks to complete.  The process of finding a landfill site and getting waste acceptance for Japanese knotweed disposal is all part of the service which PBA provide.
 
Haulage: off site Japanese knotweed disposal will require a waste transfer license. The  process of taking waste from the site of origin to landfill requires a duty of care where records and documentation are kept by all parties. When transporting Japanese knotweed lorries must not be over filled and waste should be covered.
 
Homeowners: it is not just commercial and public organisations that need to comply with waste regulations. Anyone found guilty of an offence will be liable so make sure you understand the laws behind Japanese knotweed disposal. Fundamentally you can't take Japanese knotweed to green waste transfer stations. You must not put knotweed material (roots, stems, leaves) in to your rubbish bin and burning or treating knotweed waste first will not make a difference.  Where home owners need to dispose of Japanese knotweed waste it is advisable that they contact PBA so an Environment Agency-compliant and affordable solution can be found.  
 
On site disposal:  It is possible to bury knotweed within the property it has originated from. Equally a process of sifting rhizome from soil can help to remediated land although informed advise should be sought. With on site disposal there are processes involved which need to be complied with if you are to remain within the law; if this is of interest PBA can advise further. Knotweed can be treated on site or relocated within the site of origin and then treated. Please contact PBA for further advice.
 
The Environment Agency's stance:  the Environment Agency  consider that  once land has been impacted with Japanese knotweed it will always be impacted. They favour on site Japanese knotweed control methods over off site Japanese knotweed disposal. This means that informed advice must be sought when considering an on site solution since the legacy of remediation must be robust. For example sifting rhizome from soil on its own does not remediate impacted land. Therefore if a developer then utilised such material within residential gardens it would only cause problems for future home owners.
