Multriwell and gas conversion
Multriwell is a patented innovative degassing solution that stimulates biological activity in landfills. The resulting landfill gas is efficiently captured so that it can be burned or converted into sustainable gas or electricity. Moreover, by capturing this greenhouse gas it is no longer released into the atmosphere. This process is also known as Waste-to-Energy.

Soil protection

Tritech Natural is specialised in the development of bottom liners and other solutions for soil protection. We operate in a wide range of sectors, including landfills, landscaping, industry and infrastructure.

Waste-to-Energy and Waste-to-Value

We provide solutions for the construction of new landfills but also for the remediation of existing sites with environmental contamination issues. In addition to Trisoplast, our Multriwell® system is an effective solution for intensively degassing landfills and accelerating the biodegradation process. We convert the biogas that is produced, which is rich in methane, into a valuable source of sustainable energy. By capturing this greenhouse gas it is no longer released into the atmosphere. In addition, compensation is available for every tonne of CO2 saved through the CO2 emissions trading scheme, providing a welcome return on investment for both operators and investors. Waste-to-Energy and Waste-to-Value!
