How to Use a Waste Carrier to Take Japanese Knotweed Off-SiteĀ 

Japanese Knotweed is an invasive plant that can cause significant damage to buildings and other structures if left untreated.

The plant can grow up to three meters in height, and its roots can extend up to seven meters below ground level. As such, Japanese Knotweed requires specialized treatment, and it is classified as controlled waste under the Environmental Protection Act 1990. If you need to remove Japanese Knotweed from your property, you must use a licensed waste carrier to transport the waste off-site. In this article, we will explain how to use a waste carrier to take Japanese Knotweed off-site.

What is a Waste Carrier?

A waste carrier is a licensed company or individual who is authorized by the Environment Agency to transport controlled waste. If you need to transport controlled waste, you must ensure that you use a licensed waste carrier. This requirement applies to both commercial and domestic waste. By using a licensed waste carrier, you can ensure that your waste is being transported and disposed of legally and safely.

How to Find a Licensed Waste Carrier

To find a licensed waste carrier in your area, you can use the Environment Agency’s public register. The register allows you to search for waste carriers by name, location, and type of waste they are licensed to carry. Once you have found a licensed waste carrier, you should check that their license is valid and up to date.

Preparing Japanese Knotweed for Transportation

Before you transport Japanese Knotweed off-site, you must ensure that it is properly prepared. This includes cutting the stems down to ground level and removing all soil and roots from the plant. You must also bag the waste in heavy-duty, labelled bags to prevent any cross-contamination. Japanese Knotweed waste bags should be clearly marked as “invasive plant waste” and display a hazard warning symbol.
