2. Company Profile
• Based in The Netherlands
• Main workfield: construction of
scientific landfills, remediation of
previous dumpsites.
• Specialist soil protective provisions
and landfill degassing technology
• First landfill construction in 1995
• Worldwide supply of patented
technologies in partnership with
local specialized companies.
• Track record: >12 Mio m2 wordwide

3. Protective measures for Soil, Groundwater and
Atmosphere go hand in hand with Waste to Energy
2. Leachate => Isolate, collect, treat, prevent
1. Landfill (methane) gas => Isolate, collect  Waste to Energy
3. Durable isolation and far-reaching
degradation of organic waste
=> minimum aftercare

4. Trisoplast >99% natural mineral mixture
Sand 1,000 kg
Bentonite 130 kg
(dry clay powder)
Polymer 2.6 kg
(dry grains from big-bag)
Ready mixture
(watercontent 7 – 10%)

12. Our company and India
• All Trisoplast barriers in the Netherlands (>90% of total) of last 7
years are build with bentonite from Gujerat as well as various of
our international projects.
• While visiting India contacts to National Solid Waste Association of
India and to Indian Institute of Technology Bombay started over 7
years ago.
• Participation as a speaker on first NSWAI Landfill Conference in
Coimbatore in 2009.
• Extensive research study ITT Bombay on performance of
Trisoplast has been performed.

13. Future of our company in India
• Quality of Landfill technology in India is very poor and very price
driven, if any measures are taken at all.
• Lack of proper specifications for mineral barriers by regulators.
• Shortage of suitable clay materials for construction of landfill
barriers. Inferior materials and alternatives are used.
• Converting landfill gas to energy can create high value and can
give considerable financial support to financing the construction
and exploitation of new artificial landfills and the remediation of
old dumpsites.

14. Future of our company in India
• Our know-how, Trisoplast and Multriwell technology can
contribute largely to the national mission on clean India by
creating high quality solutions for the construction of artificial
landfills and remediation of dumpsites while creating high Value
resulting from intensive degassing and waste to Energy at the
same time.
