Eco-innovations
At Environet, we care about the environment. Our goal is to be a zero-waste, carbon-neutral business whilst delivering environmental benefits for our clients, namely the removal of harmful invasive plants

Our Xtract™ method
Our goal is to protect local environments from invasive plants using eco-friendly methods. Going one step further, we’re focused on harnessing the extraordinary ability of invasive plants such as Japanese knotweed to absorb carbon, reducing CO2 levels in the atmosphere.
We recognise our business activities create waste and emissions to land, air and water which we seek to mitigate as best we can. We don’t like adding excessive amounts of dangerous herbicides to the environment, that find their way to watercourses. As far back as 2008 we thought it eco-crazy to dig up knotweed infested soils from one site only to dump it in a landfill site, many miles away. We wanted a zero-waste solution, so thinking caps went on and our R&D team came up with XtractTM, our screening process to separate and remove knotweed, that today saves thousands of tonnes of perfectly good soil filling up precious landfill sites across the UK.


Biochar from knotweed
The Xtract™ process results in tonnes of rhizome and root material being removed from the ground every year. We hate waste, so got the R&D team deciding how best to deal with this plant material. The R&D breakthrough came with the production of biochar from invasive weeds. We created a prototype biochar retort which pyrolyzes the material, rendering it inert.
A few additional steps create biochar, a superb soil conditioner which improves soil fertility and yields of desired plants. But more importantly, the biochar is 99% carbon, captured from the atmosphere by the invasive plants and then stored in the ground where it remains for hundreds if not thousands of years – carbon sequestration its called by climate scientists.
Carbon Capture & Storage (CCS)
Carbon capture & storage (CCS)


Japanese knotweed
- Invasive & destructive
- Displaces native flora
- Not welcome in the built environment


Rhizome extraction
- On-site remediation
- Zero herbicide use
- Zero waste to landfill
- Quick & effective


Biochar production
- Destroys rhizome
- Stores captured carbon
- Creates soil conditioner

Soil conditioning
- Improves soil health
- Long term carbon storage
- Restores soil fertility
- Increased yields
Climate change scientists call this carbon sequestration or carbon capture and storage (CSS) and recognise it as a positive in tackling climate change.
We’re proud to have pioneered eco-innovations that mean as a business, we are well on the way to being carbon-neutral and hopefully carbon negative in the future.

What our clients say
Reviews
Richard responded to my email asking…
“Richard responded to my email asking for identification from pictures of the plants, immediately. This service is free of charge. All they ask for is a donation to a charity, which is really nice of them. Would definitely recommend them.”
Lovely company
“Lovely company. I am buying a flat in a high risk japanese knotweed area and spotted some suspicious looking shoots in the garden. Emailed photos to Environet who responded super speedily to reassure me it wasn’t knotweed. They asked for a donation to one of their justgiving charities instead of charging a fee for identification which is such a lovely idea!”
I contacted Environet Uk to discuss my concern about Japanese knotweed.
“I was advised how their identification system operated and was asked to send clear photographic images by email, which I did. Within 3 hours, I received a response. Very impressed by the professional manner this was dealt with. Thank you.”
Fantastic identification service!
“Fantastic identification service! I received an email response 1 hour after I sent the company an email with photos. I was advised that the weeds in the photos were not Japanese knotweed which was a huge relief.”
Japanese knotweed identification
“I Can’t fault how professional this company is I spoke with a very professional lady on the telephone that gave me all the information and support we needed.This was followed up by a assessment of some pictures which has given us the piece of mind we need. Thank you”
