• the interdependencies between
water, energy and food security
• the synergies and competing uses
of water, land and energy-related
resources.
• a fundamental shift, from a mono
sectoral to a cross-sectoral, system
approach
• “Think out of the box”
• the Nexus approach challenges
existing structures, sector policies
and procedures.
• The three "supply securities" water,
energy and food to be protected
and used in a balanced manner.
The Urban nexus - a tool contributing to greater resource efficiency
A multi level and multi sectoral approach, highlighting:

approach sustainable (SDG No. 17)
• Colleges, training institutes and universities are the “cradle” for innovations
(living innovation labs)
• Students, trainers and professors - all of them “natural” multipliers.
• Training institutes concentrate on research, training and extension work
• Integrate Nexus approach into the curricula of training institutes and implement
within their extension work in collaboration with Municipalities
• Cooperation networking between training institutes to be established:
BISCAST/Philippines and King Mongkut’s University of Technology
Thonburi/Thailand (KMUTT), Chulalongkorn University/Thailand and
Mongolian University of Science and Technology (MUST), Indian
Administrative Training Institutes (ATI)

MYT® breaks household waste down into its
four components, treats them accordingly to
their specific material and extracts the
maximum potential from them.
MYT ® is an economical, reliable and low-
emission solid waste treatment system.
• With MYT ® the maximum energy and raw
material extraction from household waste is
possible.
• MYT ® is cost-effective, without negative
environmental effects.
Solid Waste management Concept
Waste to Energy

Profit with the innovative and intensively tested process:
• 97% recyclables - water, minerals, metals, fuels and biogas.

Vacuum sewerage systems have the least environmental
impact and the lowest carbon footprint of any municipal
sewerage system.
Vacuum sewerage systems are collecting waste-water by
vacuum means, thereby minimizing:
• Risks to the Environment
• Odor, Diseases, Contamination
• Energy & Water Use
Advantages of vacuum systems for investors & operators:
• Speed of construction is greatly increased
• Considerable savings in construction costs
• Much shorter construction period
• Pipelines laid in shallow and narrow trenches
• Closed systems with no leakage or smell
• No manholes along the vacuum line & lift stations
• One central vacuum station replaces several pumping stations
