As a landfill site manager, your aim is to ensure the safe and sustainable operation of your landfill site. On the other hand, you also wish to generate the maximum possible income. To serve both those goals, we are pleased to introduce Multriwell®: a revolutionary method for gas extraction that is efficient, environmentally-friendly, safe and profitable.

The Multriwell system consists of a close-knit network or grid of vertical and horizontal flexible wells for maximum gas extraction, combined with a capping construction. This system ensures the optimum flow of all extracted gas, without loss or emissions into the atmosphere. This sustainable and low-maintenance system enables you to extract more gas from your landfill site in a shorter time than using traditional systems.

The perforation of the waste by the Multriwell system accelerates and intensifies the biodegradation processes in the landfill site. As a consequence, the site can be transferred to new – e.g. recreational – use more safely and sooner.

The advantages of Multriwell

Optimum gas extraction

Shortly after putting the Multriwell system into use up to even 10 times more gas can be extracted compared to the traditional system. On the one hand this is achieved thanks to the close-knit grid of flexible wells that creates a larger flow area surface and as a consequence a faster gas discharge. On the other hand, placing the type V Multriwell’s in a close-knit grid, the leachate present in the landfill site is distributed more evenly and poorly accessible areas within the waste are penetrated and thus more successfully reached. The result is a bio reaction that in turn leads to higher and faster production of landfill gas. In addition, the Multriwell system enables you to adjust the manifolds to extract the optimum percentage of methane. Using the highly cost-efficient Multriwell system your investment generally should pay for itself within a couple of years.

Sustainable energy

By connecting the system to a generator you can even generate sustainable energy or heat from your waste!

Multriwell and the landscape

Multriwell is a very attractive system not only for you but also for the environment. Multriwell for example does not require the installation of unattractive and easily-damaged gas wells that blot the landscape. In addition, the manifolds are embedded so that the only point visible in the landscape is a manhole cover.
