Herbicide-free weed control with Weedingtech

Weedingtech, the world-leader in supplying herbicide-free systems for controlling unwanted vegetation, has just received an investment from environmental fund manager, Earthworm.

Earthworm’s £2.2m investment comes at a time when the herbicide-free sector is gaining huge traction around the world. The widespread use of traditional chemical herbicides like glyphosate has long been challenged, with international concerns about its impact on the environment and the potential threat it poses to human health.

Recent legislation around herbicides, and their use in built up public spaces, is increasing as the topic comes under ever greater scrutiny from the general public. Governments and regulators are increasingly restricting the use of these chemicals in cities, leaving the organisations that manage those cities in need of new technology.

Launched in 2011, Weedingtech has a vision to create highly-effective, environmentally-friendly systems for managing outside spaces, which are safe to use around people, animals and waterways, and available for organisations who want or need to reduce their reliance on traditional chemical herbicides.

Foamstream – Weedingtech’s patented process – is a unique combination of hot water insulated by a bio-degradable foam (made from natural & renewable plant oils and sugars) to kill unwanted vegetation. It is used extensively across the Americas, Europe and Australasia with clients including New York City Parks, The London Borough of Hammersmith and Fulham, The London Borough of Southwark, and Unified School Districts up and down the Californian coast.

Leo de Montaignac, Weedingtech CEO, commented on the funding: “We believe the investment from Earthworm recognises two key things. Firstly, the success Weedingtech has had to date supplying the market with a popular and essential alternative to traditional chemical herbicides. And secondly, the global high-growth potential that the herbicide-free sector holds as organisations increasingly look to reduce their reliance on traditional chemical herbicides.
Weedingtech was founded on very similar values to Earthworm in that we wanted to develop and supply products that benefit the environment. It’s an exciting time to be in this sector and we are delighted to have a new investor who shares our vision and values.”

Earthworm Investment Manager, Laurence Blair, said of the investment: “Weedingtech is just the sort of business we are looking to support. It is vital for responsible businesses that are greener, cleaner and safer for the environment to have the opportunity to make their mark.”
