Green light for green weed control

Green light for green weed control: Greentown Environmental Ltd and Weedingtech’s Foamstream have been chosen by Dublin City Council for the provision of herbicide weed control across the Dublin City area.

It is the first contract of its kind in Ireland, with the council making the bold decision to move away from herbicide-based weed control and seek greener alternatives. Greentown has been carrying out weed control for Dublin City Council since 2010, initially as a subcontractor before securing the principal contractor role in 2014.  Greentown is a weed control company, not a chemical company, and in 2017 they started exploring glyphosate alternatives.

In 2018 they trialled several chemical-free methods and Foamstream was the clear winner.  With a strong belief in this product, Managing Director John-Ross Armstrong decided to heavily invest in the equipment required to carry out this service to its full potential. “We are responsible weed control providers and we wanted to source a viable alternative, so we have this as an option to offer our clients.” He says. “We are conscious that there has been a shift towards greener methods, and we wanted to ensure we have a solution and that we are the market leader.”

Foamstream is an innovative approach to weed control and has the desired benefit of being completely herbicide free.  Its patented low-pressure process combines heat with biodegradable foam, making it safe for use around people, animals, and delicate environments.  The foam is created through a mixture of plant oils, wheat proteins, and sugars. It is supplied by Furlong Equipment, the exclusive importer and distributor of the solution to help organisations in Ireland make outdoor areas greener, cleaner and safer. They customise the machines for county councils and public works and, for Greentown, modified the skid unit to load on the truck, and added an extendable boom.

A representative of Dublin City Council was asked why the council made this decision.

“Action 9 of The Dublin City Biodiversity Action Plan 2015-2020 states the Council should: ‘Prepare and implement a pesticide reduction strategy within Dublin City Council.  The use of herbicides and pesticides by Dublin City Council will be examined, minimizing, and where possible, eliminating their use. This will require a clear and well-thought-out series of actions, which does not entail an overnight switch to a new regime, but rather a structured step-by-step approach. However, as part of the Dublin City Biodiversity Action Plan 2015-2020, Dublin City Council will develop a transparent strategy for minimizing pesticide use, which will be an exemplar for other organizations and authorities within the City’. As part of this minimisation programme, Dublin City Council sought tenders for alternatives methods for the control of weeds other than the use of glyphosate in line with Dublin City Council Biodiversity Plan.”

The method behind Foamstream is the longer a plant is kept in the kill zone (temperatures above 57˚C) the better.  By providing a layer of foam to the water, its acts as an insulator and holds the heat from the water in the kill zone for long enough to penetrate the leaf’s waxy outer layer, and travel down the stem and into the roots. This severely damages the plant, either killing it or causing it to die back.  The main benefits to using this kind of treatment are used in all weathers, on any surface, all-year-round. It delivers instantly visible results and is herbicide free.

“Foamstream is a great alternative to traditional methods. It has immediate effects on roadside verge weeds and uses organic means to do so.” Says Dineka Maguire, Greentown’s Dublin Divisional Manager. The weeds overtime then decompose naturally leaving streets weed-free.  The public have responded positively to this service and are delighted to see an alternative to herbicide-based methods. Members of the public are at first curious as to how the machine works, however, once we engage with them, they are delighted we are Foamstreaming their streets.”
