• 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

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

Wastewater Collection - Vacuum Sewer Systems

Why Vacuum Sewer Systems?
