How to make it work
GIZ NEXUS: INTEGRATED RESOURCE
MANAGEMENT
•
The nexus approach aims at contributing to sustainable development
through the integrated planning and management processes of the key
sectors of energy, water, and food security.
•
The project is providing technical advice to municipal
administrations/planning offices to oversee the design, planning and,
where possible, implementation of practical nexus initiatives
•
Bantan Waste-to-Energy model is an example of converting burden
(solid waste) into resource for electricity production – solving
environment and social problem while achieving profitable ecological
business model

BANTAN’S (SSLTES) MODEL REDUCES ENVIRONMENT
AND SOCIAL IMPACT
Sustainable Sanitary Landfill to Energy System (SSLTES)
Landfill lining - Protection of leachate contaminating the soil
Leachate Collecting and Treatment – Reduces odor from leachate and preventing untreated leachate
being discharged into the environment
Landfill Gas Collecting and Utilization – Reduces odor from landfill gas and green house gas effect (20
x CO2)
Daily (soil) Cover and Small Open Area (Working Surface) Dumping Method – Reduces possibility of
wind blowing away the garbage, reduces insects and other animals, reduces odor, reduces possibility of
fire
Final covering (when the landfill cell is closed) – Reduces the production of leachate through
precipitation
Landfill Rehabilitation Plan – Allows the land to be reused for landfilling, and extract valuables from the
old garbage: RDF, Daily Cover, Fertilizer, and sellable metals and glass etc.
Usage of Leachate and decomposed organics as fertilizer – Enable the surrounding landfill area to be
used fro growing vegetation – plants which are not within the food chain.
